Aims. This article aims to review the literature published to date on the types, current use, the biomechanical effects and adverse effects of maternity support belts for low back pain during pregnancy, to identify future research directions. Background. Lumbar/pelvic support belts are frequently recommended for the prevention and treatment of low back pain during pregnancy. Design. Systematic review. Methods. MEDLINE, CINAHL, the Cochrane Library and patents databases were electronically searched. Results. Maternity support belts belong to one of the four main types of maternity support garments, which are widely commercially-available. Current research showed limited evidence in support of the commercial maternity products regarding the effectiveness in the prevention and/or treatment of low back pain during pregnancy, other than that from the manufacturers. However, potential stabilisation effect of maternity support belt was demonstrated in some studies. Adverse effects reported include increased pain, fetal heart rate changes, skin irritation and discomfort. Conclusions. There is insufficient scientific evidence to conclude that wearing maternity support belts reduces pregnancy-related low back pain and/or pelvic girdle pain. Future research directions in the area of biomechanics and physiology are recommended. Relevance to clinical practice. This review provides comprehensive understanding of the effectiveness of maternity support belts for the relief of low back pain during pregnancy which will facilitate healthcare professionals in providing evidence-based advice to their patients.

Aims. To compare the physical fitness levels of Hong Kong and mainland Chinese school children and to study the association between any differences and their respective lifestyles. Background. Genes and lifestyle are both factors contributing to health. Hong Kong is a Chinese city with distinctive lifestyle features such as a different diet and different entertainment and education from the rest of China. Using samples of the same ethnicity and investigating differences in the physical fitness parameters between Hong Kong and mainland Chinese school children might reveal the impact of some lifestyle factors on health. Design. Survey. Method. Primary school children (n = 522) were recruited. Demographic data were collected by questionnaire. Physical fitness tests were carried out. Results. Significant differences were found in height, body weight, sit and reach, long jump, running 50 m and lung capacity. Hong Kong children were found to be taller and heavier at ages 6 and 7, but heavier with similar height to that of mainland children at ages 8-12. Other results showed better physical fitness on the part of mainland children. Discussion. Although the people of Hong Kong share the same ethnicity as the majority of mainland Chinese, the eastern-mixed with-western diet, education and entertainment of Hong Kong children differ greatly. The findings in terms of physical fitness revealed variations in body build, flexibility, cardiovascular function and muscle power between the two groups. Conclusion. Lifestyle could possibly be a key factor and predictor of physical fitness, providing strong evidence to support the interaction between lifestyle and genes in their impact on our health. Relevance to clinical practice. Lifestyle could possibly be a key factor and predictor of physical fitness and health outcomes. The finding of this study may enhance the identification of healthy lifestyle which may improve health outcomes in children. [ABSTRACT FROM AUTHOR]

Aim. The aim of the present study is to review the effects of caffeine abstinence on the quality of sleep. Background. Insomnia is a common problem and abstinence from caffeine is the most popular component in sleep hygiene advice. However, there have been inconsistent results relating to the effectiveness of caffeine abstinence in improving sleep. Design. Systematic review. Methods. We browsed several electronic databases and reference lists of articles about the correlation of caffeine consumption and sleep deprivation. We selected the articles according to predefined inclusion and exclusion criteria. Two reviewers assessed the quality of trials, which were selected according to the Jadad quality assessment scale. We included the trials scoring three or above in the systematic review and extracted their data. We assessed the heterogeneity of the studies before we considered whether or not to combine the studies' results. Results. Three randomised control trials fulfilled the selection criteria among which two trials scored >=3 on the Jadad scale. We included these two trials in our systematic review. The designs and outcome measurements of these two trials were not homogeneous, therefore, we did not combine their results. Instead, we conducted a critical appraisal. In one trial, caffeine abstinence was associated with significant lengthening of sleep duration (p < 0·01) and better sleep quality (p < 0·05). In another trial, subjects had less difficulty falling asleep on days when they drank decaffeinated coffee (p < 0·05). Conclusions. The results showed that caffeine abstinence for a whole day could improve sleep quality. Thus, health practitioners were recommended to include caffeine abstinence in the instructions for sleep hygiene. Relevance to clinical practice. This study demonstrates the effectiveness of caffeine abstinence in improving sleep quality. It provides evidence for the practice of including caffeine abstinence in sleep hygiene advice.

Aims. (i) To provide a profile of the clients who have used the Integrative Health Clinic's services, (ii) to determine the clients' extent of satisfaction with the services received and (iii) to assess whether integrative therapies can/should be recommended to other clinics. Background. Based on the integration of various health paradigms and the use of health promotion strategies, our Integrative Health Clinic in Hong Kong provides a range of different therapies for integrated symptom management. The integrative therapies are derived from conventional, complementary and alternative medicine. Design. Postal survey, followed by routine data analysis. Method. Hong Kong Chinese clients attending a residential community health clinic were surveyed about health status and satisfaction towards the services received. Results. A total of 489 clients (30.8% were male and 69.2% female) were registered with the clinic during the study period. The mean age (SD) was 47.8 (15.4) years. The customer satisfaction survey found that traditional Chinese medicine consultation was the most frequently used modality of the Integrative Health Clinic, followed by pain management. Out of the 489 clients, those who attended the Integrative Health Clinic only once in the study period for an annual health assessment and those who died during the period were excluded from the survey, giving a total of 276 eligible clients. Out of the 276 clients, 52.5% (128) responded to the survey that asked them to evaluate their satisfaction with the services received at the clinic and the performance of the clinic's practitioners who interacted with them. For practitioner performance, the percentage of respondents who gave a rating of satisfaction was found to range between 86.3-64.3%, while the percentage of respondents who gave a rating of dissatisfaction ranged from 13.7-35.7%. Overall, the survey found that most aspects of the Integrative Health Clinic's services were rated as satisfactory. Conclusion. The overwhelming satisfaction of clients with the services they received at the Integrative Health Clinic suggests that this integrative health services model could be considered for adoption in other clinics in Hong Kong and perhaps the region. Relevance to clinical practice. It is necessary to review the use of integrative therapies so as to provide more data for the evaluation of this increasingly popular modality of health services.

AIM: To evaluate the sensitivity of mean absolute amplitudes of the thoracic and the abdominal signals as a prompt indicator of the occurrence of sleep apnoea events. BACKGROUND: To provide symptomatic management of sleep apnoea, a reliable method of detecting sleep apnoea is essential to ensure that the intervention can be applied only when needed. It is also crucial to identify the threshold for the trigger of an intervention using a deployed sensor. DESIGN: Twenty-six subjects aged between 18-65 years who were diagnosed with obstructive or central sleep apnoea underwent an overnight sleep study. METHOD: Signals of nasal and oral airflow, thoracic and abdominal efforts and pulse oximetry level were recorded using a polysomnography device. RESULTS: With a 95% CI, the overall area under the receiver operating characteristic of the thoracic signal, the abdominal signal and the combination of the thoracic and the abdominal signals were 84.56, 87.48 and 90.91%, respectively. Using -20, -25 and -30% as a cut-off point, the sensitivity values of thoracic signal, abdominal signal and combination of the thoracic and the abdominal signals ranged from 70.29-86.25% and the specificity values ranged from 74.82 to 90.09%. CONCLUSIONS: Using mean absolute amplitude analysis, the results of this study showed that combination of the thoracic and the abdominal signals achieved the best overall and individual performances compared with thoracic signal and abdominal signal. Overall, thoracic signal, abdominal signal and combination of the thoracic and the abdominal signals have a good performance with an receiver operating characteristic value higher than 80%. The thoracic and the abdominal signals were good parameters for the identification of the occurrence of sleep apnoea, being as quick as the nasal airflow signal. RELEVANCE TO CLINICAL PRACTICE: These results suggested that sleep apnoea events could be identified through constant monitoring of the patient's thoracic and abdominal signals. Knowledge of these signals could help nurses to manage sleep apnoea in patients. [ABSTRACT FROM AUTHOR]

Aims and objectives. This study uses two models of nursing practice, conventional and modular design, to compare nursing activities, hand hygiene, time efficiency and nurse-patient satisfaction in medical and surgical wards. Background. Learning from the SARS epidemic pointed to the importance of quality nursing practice considerations that minimize cross-transmission of infection while maximizing patient-focused care. Hence, a modular nursing model was adopted. Design and method. This study comprised pre- and postintervention phases. Data collection tools to evaluate modular nursing practice included a work sampling observation checklist, focused group interviews with nurses, questionnaires addressing nurses' perceived competence and caring attributes, a patient satisfaction questionnaire, and a hand hygiene audit. A series of education sessions were conducted between the two phases. Quantitative and qualitative analyses were used for data triangulation. Results. Modular nursing practice, focusing on continuity of care, led to changes in the nature of direct care activities and improvement in patient/family education frequency. Also, a general increase in nurses' hand washing frequency was noted. However, when nurses perceived time pressure, a lapse in hand hygiene compliance was found. Because of human resource and inefficiency issues, some nurses in the studied wards did not embrace geographical separation for infection control. Positive correlations were found for nurses' perceived infection control practice competence and their perceived caring attributes. Relevance to clinical practice. In examining nursing practice models within complex clinical situations, the significance lies not only in the model's effects but also in other operational outcomes. [ABSTRACT FROM AUTHOR]

AIM AND OBJECTIVE: Like other health-care workers, Hong Kong nurses had their professional knowledge and skills seriously challenged during the SARS outbreak. Could current nursing practices support the care of SARS or SARS-like patients in the future? If not, alternative practices would be needed. Providing a preliminary understanding, this paper compares the conventional with different nursing delivery models in a simulated SARS ward and focuses on nurses' efficiency, infection control practices and views of the two models. DESIGN AND METHODS: This study was conducted in three phases. First, a baseline understanding of nursing practices was achieved through four workflow observations. In an eight-hour day, four research assistants observed nursing activities in the medical and fever wards. These data were used in the second phase to construct two sets of clinical vignettes, pertaining to SARS patient care in both conventional and alternative practice models. These scripts were discussed with nine nurses of various ranks from the hospital under study for their expert validation and input. In the third phase, nurse participants and patient actors enacted the vignettes in a simulated setting. Video-taped observations and four nurse participant interviews were employed. Observational data were analysed through descriptive statistics and independent t-tests. Textual data were coded and categorized for common meanings. RESULTS: Conventional practice from the findings consisted of cubicle and named nurse nursing. While the former reflected modified team and functional nursing, it did not confine patient care within a cubicle as suggested by its name. The latter depicted a modified primary nursing approach in a team, with delegation of care. Preliminary findings concerning infection control and nurse satisfaction revealed that the alternative model had an advantage over the conventional. RELEVANCE TO CLINICAL PRACTICE: This study findings lay the foundation for clinical trials, which would evaluate the significance of patient-care quality, cost-effectiveness and better human resource management by restructuring current nursing practices.

In 2003, severe acute respiratory syndrome (SARS) came to be recognized as a newly emergent form of disease that is highly contagious. The aim of this study was to describe the perceptions of nurses with SARS in Hong Kong, as the perceptions of nurses who have suffered from SARS have not been studied. Ten nurses who had suffered from SARS were interviewed, either face-to-face or by telephone, about their subjective experiences. These interviews provided in-depth, descriptive data, which were analysed using content analysis. Nine broad categories were identified: uncertainty, information control, feelings of anger and guilt, lack of preparation and fear of death, feelings of isolation and loneliness, physical effects, support, change of perspective of life, and change of perspective of nursing. Although the dreaded disease affected the nurses tremendously, both physically and psychologically, it has also had its positive side. As a result of experiencing the illness, the participants came to treasure relationships, health and everyday life more. In caring for patients, they came to see the world more from the perspective of the patients. They found that they need to take the time to reassure patients and families and to seriously listen to all of their concerns. [ABSTRACT FROM AUTHOR]

AIM AND OBJECTIVE: To explore in depth the experiences of nurses' caring for SARS patients in Hong Kong. BACKGROUND: Severe Acute Respiratory Syndrome (SARS) dramatically demonstrates the global havoc that can be wreaked by a newly emerging infectious disease. The current literature either has a predominantly biomedical focus or deals with the psychological impact on healthcare workers. Published studies on the lived experience of nurses caring for SARS patients are currently lacking. DESIGN: A phenomenological design. METHODS: Using methods consistent with Husserl's philosophy, eight Registered Nurses working in three regional hospitals in Hong Kong were invited to participate in sharing their lived experience of caring for SARS patients and data were analysed using Colaizzi's approach. RESULTS: The three major themes explicated were: the various emotions experienced in caring for SARS patients, the concept of uncertainty and revisiting the 'taken for granted' features of nursing. CONCLUSION: These themes, when taken together, describe the essence of the voyage undertaken by nurses who cared for SARS patients during the outbreak. The findings of this study indicate that extensive and ongoing support is needed to prepare and enable nurses to care for SARS patients during a crisis and make it easier for nurses to deal with the various uncertainties. RELEVANCE TO CLINICAL PRACTICE: The essence of caring for SARS patients is highlighted in this study. The experience of caring for SARS patients prompts nurses to find meaning in their experience(s), and to develop knowledge and attitudes on how best to care for patients and prepare for a new crisis in the future. This paper considers a more in-depth understanding of the lived experience of nurses during the crisis and the relevance of this perspective for education and support of nurses.

This paper explores students' views of an online learning initiative within a post-registration degree in nursing in Hong Kong. A self-administered questionnaire was used for data collection. One hundred and ninety eight students completed the study. Online learning was seen to be convenient allowing students to study at their own pace and time. Students reported that online learning enabled them to hold a higher level of accountability for their own learning and to learn independently. Not all experiences were positive. A major hindrance to online learning was the inadequate opportunity for human interaction which was deemed necessary for establishing peer support and developing in-depth group discussion on subject matter. These findings provide a guide for further development and improvement in online teaching and learning methodologies. [ABSTRACT FROM AUTHOR]

PURPOSE: To assess the extent of and reasons for non-attendance in the Orthopaedic and Trauma Specialist Outpatient Department. METHOD: The first stage was a retrospective survey and the second stage was a structured face-to-face interview. RESULTS: In stage 1, monthly statistics (12 months) were reviewed. There were no significant statistical differences between the attendance and default counts/rates and the seasons, except the default rate (F = 5.537 (3,8), P = 0.024). The mean default rate ranged from 17.6 to 20.62% over the four seasons. April-June had the lowest mean default rate. In stage 2, 50 subjects were recruited randomly; 25 had attended the clinic and 25 had not. There were no significant differences in the demographic characteristics between the two groups or in the ratings of the attitudes towards the various professional groups. However, those who did not attend the clinic expressed most dissatisfaction with the waiting time, the quality of consultation, and the facilities in the waiting area. DISCUSSION: Although the exact waiting time was not recorded, this did not stop us from evaluating the work process with the aim of shortening waiting time and improving the quality of that time. To develop measures that shorten waiting time, it was necessary to review the functional process of a consultation session. The quality of waiting time can be enhanced by rearranging the waiting areas, providing more chairs, improving the lighting, and ensuring the cleanliness of the toilet facilities. An education programme that adopts a behavioural approach is suggested to help clients appreciate the value of follow-ups. [ABSTRACT FROM AUTHOR]

Background. To contain severe acute respiratory syndrome, the Hong Kong Hospital Authority set a policy that stipulated there should be no visitors to hospital wards. A helpdesk service was established with the goal of providing immediate emotional and communication support to relatives while severe acute respiratory syndrome patients were isolated during the acute phase of the illness.Aim. This study describes the results of a rapid assessment of the effectiveness of a helpdesk service designed to meet the immediate needs of relatives of severe acute respiratory syndrome patients in Hong Kong.Design. Survey.Method. Eighty-three respondents, representing about 46.3% of relatives (179), attending the helpdesk on the day of the study were recruited. Service evaluation data was collected using a self-administered questionnaire completed by respondents.Results. Nearly 100% of respondents who used the service found the delivery service with on-site counselling useful for alleviating their anxiety. However, about half of these relatives complained of insufficient information regarding the patient's condition and progress. The majority of respondents were satisfied with the service. In describing the most important traits of the service providers, caring and enthusiasm were mentioned most frequently by respondents who stated that they were very satisfied with the service.Conclusion. The results support the value of the service, and demonstrate that the service is effective in meeting relatives' immediate needs. These needs include information, aid in fulfilling their role as caretaker for the patient (delivering prepared soup) and psychological support. The results suggest that facilitation of visitation of patients by relatives via video conferencing and education of the public on the nature and course of severe acute respiratory syndrome to reduce the social stigma of having a potentially life-threatening disease should be introduced in Hong Kong.Relevance to clinical practice. The results highlight important attributes that helpers (nurses) should have in order to alleviate the suffering of severe acute respiratory syndrome patients and their relatives.

The present prospective survey was conducted in a 1200-bed hospital to examine postoperative patients' current pain intensity, most intense pain experienced, satisfaction with postoperative pain management, and differences regarding pain and satisfaction levels. All adult patients admitted to a hospital in Hong Kong for surgery, except those receiving local anesthesia, were eligible to enter this study. The patient outcome questionnaire developed by the American Pain Society was used to solicit data about patients' pain and satisfaction with pain relief. The subjects were 294 postoperative patients. Approximately 85% complained about varying degrees of pain during the 24 h prior to the assessment of their pain. When interviewed, most patients complained of mild to moderate pain (median = 2 on a 10-point scale), while the median for 'worst pain intensity' was 5. Approximately 80% of the subjects indicated that both the nurses and physicians reminded them to report pain when it occurred. Only 143 (48.6%) agreed that the nurses and physicians sufficiently emphasized the importance of pain relief. Those who received acute pain services, provided by anesthetists, reported lower levels of current pain intensity. Over 65% of the subjects were satisfied with all levels of health care providers, regarding their postoperative pain management. [ABSTRACT FROM AUTHOR]

To investigate whether the application of manual pressure to the injection site before intramuscular injection reduces pain. An experimental study with intrasubject comparison was conducted using manual pressure to reduce pain associated with intramuscular injection. Seventy-four subjects, participating in an immunization vaccination campaign, were recruited by convenience sampling from a university. They were required to receive two doses of vaccines via intramuscular injections. One was given in a conventional way, i.e. without manual pressure being applied prior to the injection (control condition). The other was given with manual pressure being applied prior to the injection (experimental condition) for 10 seconds. The two conditions were randomly allocated for each subject. The instrument for measuring the perceived pain intensity was the Pain Intensity Verbal Rating Scale (Cantonese). To ensure the consistency of manual pressure being applied to the injection site, a mechanical pressure sensor device was used to record the manual pressure being applied. The mean manual pressure applied was 190.82 mmHg (SD=5.25). Results demonstrated a significant difference in the perceived pain intensity for experimental and control conditions. Subjects with manual pressure applied before injections reported lower pain intensity scores, whilst those without the application of manual pressure before injections reported higher pain intensity scores. Applying manual pressure to an injection site before performing an injection could be an effective means of decreasing pain intensity. [ABSTRACT FROM AUTHOR]

For many hospital patients, the experience brings pain and anxiety. Unfamiliar surroundings, various diagnostic and therapeutic procedures, and the sight and sounds of medical procedures exacerbate pain and anxiety. To block off the anxiety-inducing sights and sounds of hospital surroundings and create a pleasing environment, the therapeutic potential of visual stimulation as a nursing intervention was investigated. In a randomized, controlled, cross-over study, pain was produced by a modified tourniquet technique in 46 healthy volunteers. Subjects were randomly allocated to two groups (Group V and Group B) with subsequent cross-over. Those in Group V watched a soundless video display of natural scenery during tourniquet inflation, whereas in Group B subjects watched a static blank screen. Pain threshold was defined as the time when subjects reported the first detectable pain, whereas pain tolerance was the time the pain was reported to be intolerable and deflation of the tourniquet was requested. With the use of visual stimuli, there was a significant increase in pain threshold (P < 0.05) and pain tolerance (P < 0.01). Gender and the sequence of visual stimuli did not have any significant effect on pain threshold and pain tolerance. Further studies specifically addressing level of anxiety and physiological data correlated with pain scores and visual stimuli are needed. The findings have implications for nurses and other healthcare professionals to use various visual stimuli as positive adjuncts to other methods of pain relief and for different pain conditions in clinical areas.

The purpose of the study was to explore the diagnostic reasoning process among nursing students with different learning environments. A case-study design was adopted. Twenty subjects were randomly drawn from the last year of a pre-registration nursing programme in two institutions, 10 from a university and 10 from a nursing school. They were asked to complete the Bigg's Study Process Questionnaire and identify the differential diagnosis for the three simulated scenarios. The results showed no significant difference in study approaches between the two groups. Two subjects from the university made an incorrect differential diagnosis, as did one from the nursing school. Subjects from the university showed a mix of horizontal (66.6%) and vertical reasoning patterns (33.4%), while those from the nursing school used horizontal (100%) reasoning patterns. The results indicated that all subjects from the nursing school adopted backward chaining strategies (horizontal) for decision-making, i.e. hypothesis-driven. About a third of the subjects from the university adopted forward chaining strategies (vertical), i.e. data-driven. The study did not show any particular advantages from either of the two learning environments in terms of study approach. However, it highlighted the variations in decision strategies among students in the university setting. [ABSTRACT FROM AUTHOR]

Background: Nurses with a strong professional self-concept tend to exhibit a positive mindset and strong work engagement, delivering high-quality patient care. Although numerous quantitative studies have examined the factors impacting professional self-concept, there remains a limited exploration of these factors from the perspective of nurses themselves., Methods: This qualitative descriptive study uses the PERMA theory and Social Cognitive Theory as the theoretical framework. Semi-structured interviews were conducted with 15 nurses from six public hospitals in China. The data were analyzed thematically using a combination of inductive and deductive approaches., Results: Nurses' understanding of professional self-concept could be divided into four categories: professional identity, competence, care, and knowledge. Factors influencing nurses' professional self-concept were categorized into eight subthemes in three domains: (1) personal factors, including psychological qualities and attitude towards the nursing profession; (2) occupational-related behavioral factors, including role-oriented behavior and knowledge-oriented behavior; and (3) work environment and external factors, including external evaluation and perceptions of nurses, time allocation, nursing work tasks, work atmosphere, school education, and perceived supports., Conclusions: This study found that, although nurses had different personal experiences, their perceptions of professional self-concept were similar. Nurses' professional self-concept is a multidimensional concept and involves various factors, such as personality, work-related characteristics, environment, and family. To thrive in a nursing career, nurses must discern the factors that can enhance or hinder their professional self-concept. By identifying and adjusting these factors, personalized support and positive interventions can be tailored to meet nurses' specific needs, which ultimately nurtures their professional development., Trial Registration: This study was registered on December 14, 2022, in the Chinese Clinical Trial Registry (ChiCTR2200066699) as part of our ongoing study., (© 2024.

Background: Children's overall psychological well-being is a concern for parents and adults worldwide. Mindfulness appears to be a promising intervention for enhancing children's psychological well-being, and its effectiveness has been well-documented. However, there is a paucity of data on the feasibility and acceptability of implementing mindfulness-based interventions (MBIs) for children; this is a crucial factor in determining whether MBIs can be utilized to benefit children. The aim of this study was to determine the feasibility and acceptability of implementing MBIs among Hong Kong children., Methods: Seventy-eight children (mean age = 9.06, SD = .375) were recruited from a primary school in Hong Kong and received MBIs in a single session that lasted about 2 h. The intervention's feasibility was determined in terms of retention rates, while acceptability was based on qualitative feedback from the children., Results: The results show that there were high retention rates (96%). Qualitative analyses of children's feedback revealed that they experienced enhanced well-being, and enjoyed and benefited from the interventions., Conclusions: This study shows the high feasibility of MBIs in children, supporting the conduct of an efficacy trial to examine the effects of MBIs among children. Support from school teachers and measures to raise and maintain children's interest in mindfulness could facilitate the conduct of a study., (© 2024. The Author(s).)

Aim: To identify latent profiles of nurses' subjective well-being (SWB) and explore its association with social support and professional self-concept., Design: This study used an online survey and cross-sectional latent profile analysis design., Methods: A total of 1009 nurses from 30 hospitals in Guangdong Province, China, were selected using convenience sampling. An online questionnaire survey comprising the following scales was distributed: Index of Well-Being, Nurses' Professional Self-concept Questionnaire and Multidimensional Scale of Perceived Social Support. Nurses' SWB was examined and categorized into profiles using nine Index of Well-being items as explicit variables and ordinal logistic regression analysis was performed to explore factors related to the distinct categories., Results: Nurses' SWB was divided into four latent profiles: extremely low, low, moderate and high. Regression analysis showed that social support and professional self-concept influenced SWB. There were statistically significant differences in age, title, working years, social support and professional self-concept among nurses in the different well-being categories. Ordered logistic regression analysis showed that social support and professional self-concept are associated with different SWB profiles., (© 2024 The Authors.

Background: Frailty is an aging-related syndrome leading to high mortality in older adults. Without effective assessment and prevention of frailty, the incidence of frailty and relevant adverse outcomes will increase by 2050 as worldwide populations age. Although evidence suggested heart rate variability (HRV) is a potential measure of frailty, the role of HRV in frailty assessment remains unclear because of controversial findings. This study examined the effects of posture on HRV parameters in non-frail and prefrail individuals to understand the role of HRV in assessing frailty., Methods: Forty-six participants aged ≥ 50 years were recruited between April and August 2022. Frailty was defined using Fried's criteria. HRV was measured in standing, sitting, and lying postures, respectively, using a Polar Watch, and analyzed using Kubios HRV Standard 3.5.0 (Kubios). The five most commonly used parameters were examined, including standard deviations of all normal-to-normal intervals (SDNN), root mean square of the successive differences (RMSSD), low frequency (LF), high frequency (HF), and LF/HF. Independent t-tests and Mann-Whitney tests were used for inter-group comparisons. Friedman tests were used for intra-group comparisons across postures., Results: The non-frail group showed significant differences in HRV parameters across postures (all p < 0.05), whereas the prefrail group did not demonstrate any difference (all p > 0.05). The differences in the non-frail group included higher RMSSD and HF in the lying posture compared to those in the standing posture (29.54 vs 21.99 p = 0.003, 210.34 vs 96.34 p = 0.001, respectively), and higher LF and LF/HF in the sitting posture compared to those in the lying posture (248.40 vs 136.29 P = 0.024, 1.26 vs 0.77 p = 0.011, respectively)., Conclusions: The effects of posture on HRV were blunted in the prefrail group, which suggests an impaired cardiac autonomic functioning. Measuring the effects of posture on HRV parameters may contribute to frailty assessment. However, further evidence from larger cohorts and including additional HRV parameters is needed., (© 2023.

This pilot study aimed to explore the impact of a compassion-oriented training program on Personal Care Workers (PCWs) in a nursing home. A mixed-methods approach was used, including pre- and post-questionnaire surveys to measure changes in compassion, and in-depth interviews and daily diaries to explore PCWs' perceptions and experiences. A convenience sample of five female PCWs from a nursing home in Hong Kong participated in the study. The quantitative results showed that the PCWs experienced a decline in compassion after participating in the program. The qualitative data analysis identified three themes: (1) the multifaceted nature of compassion, (2) barriers and threats to compassion, and (3) transfer of skills at the workplace. Overall, These findings highlighted the complexity of implementing effective compassion training programs in nursing home, and emphasized the importance of recognizing the multifaceted nature of compassion and addressing barriers and threats to compassion in the workplace., Competing Interests: Declaration of Competing Interest The authors declare that there are no potential conflicts with respect to the research, authorship, and/or publication of this article., (Copyright © 2023 Elsevier Inc.

Objective: To examine (1) the effectiveness of polylactic acid (PLA)-based biomaterials in wound healing, (2) their effects on wound infection prevention, and (3) their safety compared with existing biomaterials., Data Sources: Data sources included PubMed, MEDLINE, Cochrane Library, CINAHL (Cumulative Index to Nursing and Allied Health Literature), CNKI (China National Knowledge Infrastructure), WEIPU, and WANFANG databases., Study Selection: Investigators included 14 studies discussing the effects of PLA-based biomaterials in cutaneous wound healing published from 2000 to 2021., Data Extraction: Authors extracted the following information from the selected studies: general information, study type, type of wound, PLA-based biomaterials and techniques, study period, outcome measures, and results., Data Synthesis: Polylactic acid-based biomaterials may promote wound healing through wound area repair, collagen deposition, angiogenesis, and cell activities, which are related to the good biocompatibility, biodegradability, and moisture management properties of PLA. A proper product structure may also help. Both the native PLA materials and PLA blends seem to be antibacterial, although more evidence is needed for the native PLA products. Because there was no severe adverse event or obvious cytotoxicity observed in the included studies, PLA-based biomaterials are likely safe., Conclusions: Polylactic acid-based biomaterials may be good wound dressing materials, although more evidence is needed to support their broader application in wound care., (Copyright © 2023 the Author(s).

Background: To explore the effects of Ving Tsun (VT) sticking-hand training on knee joint proprioception and leg muscular performance among community-dwelling middle-aged and older adults., Methods: Thirty-three middle-aged and older adults were randomly assigned to either the VT or control group. The VT group received sticking-hand training twice/week for 3 months. Data were collected before and after the intervention period. The primary outcome was knee joint repositioning error, which was measured using knee joint active repositioning tests. The secondary outcomes included the maximum muscle strength and time to maximum muscle strength of the major leg muscles., Results: No significant group, time, or group-by-time interaction effects were found for the knee joint repositioning error (p > 0.05). The maximum muscle strength of the knee flexors increased over time in the VT group only (p = 0.038). In addition, the time to maximum muscle strength in the hip extensors and flexors increased over time in both groups (p < 0.05). For the knee extensors and flexors, the time to maximum muscle strength increased in the control (p = 0.027) and VT (p = 0.019) groups, respectively, over time., Conclusions: VT sticking-hand training could improve the maximum muscle strength of the knee flexors but could not attenuate the age-related deterioration in leg muscle contraction speed nor improve knee joint proprioception among community-dwelling middle-aged and older adults., Trial Registration: ClinicalTrials.gov NCT03318289.

Rationale: The 21st century has seen vast flows of displaced people. In the year 2020 alone, an estimated 11.2 million were forcibly displaced as a result of persecution, conflict or generalized violence. The torment and fear of war, persecution and threat to life, whether in the home country, during the process of fleeing, or in the post-migration host country, can be extremely traumatic to these marginalized populations. Hong Kong is not a signatory to the 1951 UN Refugee Convention, but the territory has signed the 1967 UN(CAT) which requires the former colony to allow people who flee for their lives to have their cases processed in Hong Kong. Currently there are around 14,000 cases in Hong Kong, some of whom have been in Hong Kong for more than a decade, waiting for their claims to be processed, living on meagre government subsidies and with no right to work., Objectives: The paper examines the mental health of asylum-seekers and refugees in Hong Kong and the factors associating with their mental health., Method: A sequential mixed methods approach was conducted among asylum-seekers and refugees in Hong Kong between October 2019 and mid-2020. It comprised a pilot quantitative survey conducted with 47 participants, and follow-up qualitative interviews with 16 of the 47 participants. Survey results were analyzed using statistical measures while the qualitative in-depth interviews were thematically analyzed to identify emergent patterns and categories., Results: Results from the quantitative data identify 52.2% of the asylum-seekers taking part as having symptomatic anxiety, 55.3% as having symptomatic depression and 54.3% as having overall problems. Qualitative results show that asylum-seekers and refugees cited lack of work and poverty as key factors affecting their mental health and well-being. Fear of being sent home was expressed by respondents who were married or having children for the fear of being separated from each other., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.)

This study compared the effectiveness of tai chi (TC) muscle power training (MPT), TC alone, MPT alone, and no training for improving the limits of stability (LOS) and motor and leg muscular performance and decreasing falls in children with developmental coordination disorder (DCD). One hundred and twenty-one children with DCD were randomly assigned to the TC-MPT, TC, MPT, or control group. The three intervention groups received TC-MPT, TC, or MPT three times per week for 3 months. Measurements were taken before and after the intervention period. The primary outcomes were the LOS completion time and dynamic LOS scores. The secondary outcomes included the Movement Assessment Battery for Children-Second Edition total test score and percentile rank, knee muscle peak force and time to peak force, and the number of falls. None of the interventions affected the LOS test scores. Improvements in the peak forces of the knee extensors and flexors were demonstrated in the TC (p = 0.006) and MPT groups (p = 0.032), respectively. The number of falls also decreased in these two groups (p < 0.001). Thus, clinicians may prescribe TC or MPT for children with DCD to increase their knee muscle strength and reduce their risk of falls., (© 2022. The Author(s).)

Background: Adaptive postural control is an important yet underexamined area in children with developmental coordination disorder (DCD). This study compared adaptive postural responses between children with DCD and those with typical development., Methods: This was an exploratory cross-sectional study. Fifty-two children with DCD (aged 6-9 years) and 52 age- and sex-matched children with typical development participated in the study. Their adaptive postural (motor) responses were assessed using the Adaptation Test (ADT) on a computerized dynamic posturography machine. The sway energy score (SES) for each ADT trial and the average SES of five trials for both toes-up and toes-down platform inclination conditions were recorded., Results: The SESs were lower in the DCD group than in the control group in ADT toes-up trial 1 (p = 0.009) and on average (p = 0.044). In the control group, the SES decreased from trial 1 to trial 2 for both the ADT toes-up (p = 0.005) and toes-down conditions (p < 0.001)., Significance: Adaptive postural responses were absent in children with DCD, and these children used less force (i.e., sway energy) to overcome postural instability. Therefore, both adaptive balance and neuromuscular training should be factored into rehabilitation programs for children with DCD., Competing Interests: Declaration of Competing Interest No potential conflict of interest is reported by the authors., (Copyright © 2022 Elsevier B.V.

Objective: to develop an integrative learning program for people with dementia., Method: a methodological study was conducted using Delphi technique to develop the learning program, followed by a feasibility test. An expert panel was invited to develop the integrative learning program based on the neuroplasticity and learning framework. A feasibility test was conducted to evaluate the implementation of the program in two centers after the training of personnel who run the program. Verbatim transcripts of case conferences were coded, analyzed, and collapsed into themes and sub-themes by consensus., Results: there was no indication for content modification during the period of program implementation. Qualitatively, the participating older adults showed improvement in communications, emotions, connectedness with self and others, and well-being., Conclusion: the integrative learning program was uneventfully implemented with promising results. The program is ready for full-scale research on its efficacy in multiple centers to obtain more robust evidence.

Objectives: To identify typology of pain coping in older adults and to see whether the coping types or patterns were associated with pain, physical health, and mental health outcomes., Methods: Six hundred and fifty six Chinese older adults were recruited on a convenience basis from social centers in Hong Kong. A 14-item Brief Pain Coping Scale (BPCS) was constructed on the basis of the Chronic Pain Coping Inventory. Outcome measures included pain intensity, pain disability, pain-related cognitions, depressive symptoms, health-related quality of life, and health and physical functioning (in terms of chronic illnesses, basic and instrumental activities of daily living, and self-rated health). Coping typology was identified using latent class analysis., Results: A 3-class solution based on BPCS provided the best fit to data. Class 1 used almost all coping strategies on a daily basis, Class 2 used the strategies less frequently, whereas Class 3 adopted few strategies. Yet, Class 3 was basically indistinguishable from Class 1 across the outcome variables, even though the participants had more chronic illnesses and poorer instrumental activities of daily living than those in Class 1. Class 2, however, had the poorest outcome profiles, reporting more pain, disability, depression, and health-related quality of life than the other two classes. The differences in coping could not be explained by the differential effectiveness of coping strategies across groups., Conclusion: The way coping was used, and the way it was related to pain, mood, health and functioning outcomes, varied substantially across individuals. Implications for coping skills interventions are discussed.

Background: Health literacy, the ability to access, understand, evaluate and apply health information, was found to contribute to positive health outcomes, possibly via promoting healthy behaviours. However, the specific pathways linking different health literacy skills to health and well-being have remained unclear., Methods: A cross-sectional survey with structural questionnaires was administered among 2236 adults in Hong Kong (mean age = 46.10 ± 19.05). Health literacy was measured by HLS-Asian-47. Participants' physical conditions and subjective well-being were predicted by health literacy and health behaviours with structural modelling path analysis., Results: Health literacy in finding and understanding information showed a direct effect on enhancing physical health, while applying information capacity had an indirect positive effect via promoting health behaviours, which was moderated by sex. Only among women, this indirect effect predicting fewer physical symptoms and better well-being was significant., Conclusions: Different health literacy dimensions showed distinct direct and indirect pathways in influencing health for men and women. Based on the findings, skill trainings should be developed to enhance both gender's abilities of finding and understanding health information, while the ability of applying health information should also be improved for modifying lifestyle and promoting health, particularly for women., Patient or Public Contribution: Two thousand and two hundred thirty-six adults from different districts of Hong Kong participated in the study, and responded to questions on health literacy, behaviours and health status., (© 2021 The Authors.

Background and Objectives: The 22-item Chronic Pain Self-efficacy Scale (CPSS) measures three domains of pain self-efficacy: pain management, physical functioning, and coping with symptoms. This study aims to develop a short form (CPSS-SF) that retains the multidimensional structure of the instrument., Research Design and Methods: Six hundred sixty-four community-dwelling Chinese older adults aged 60-95 years with chronic pain completed a survey. Confirmatory factor analysis (CFA) was conducted on the 22-item CPSS. Regression analyses were performed to examine the items' correlations with criterion variables. After CPSS-SF items were selected, the performance of CPSS-SF subscales in terms of accounting for pain-related outcomes was compared with the full version., Results: CFA supported a modified 3-factor model of the CPSS. On the basis of factor loadings on the 3 dimensions and the items' correlations with pain intensity and pain disability, 11 items were selected for the CPSS-SF, which correlated at .97 with the full version. Regression analyses showed that the associations of the CPSS-SF subscales with pain intensity, pain disability, depressive symptoms, instrumental activities of daily living, and physical and mental health-related quality of life, were indistinguishable from their full-version counterparts., Discussion and Implications: The CPSS-SF is a valid instrument that can be used in lieu of the full scale. Its availability will facilitate the assessment of pain self-efficacy in research and clinical settings due to its brevity but strong psychometric properties. However, the current evidence is limited to Chinese older adults; more research is needed to ascertain its validity in other age and cultural groups., (© The Author(s) 2019.

Background: Prior research has found poor health among construction workers is related to poor nutrition and low fruit and vegetable consumption. Promoting nutrition knowledge can improve dietary behaviors, but nutrition education among construction workers is limited. We evaluated the effectiveness of nutrition education on fruit and vegetable consumption among construction apprentices. In this pilot evaluative study, 36 construction apprentices enrolled in skill training programs received two 1.5-hour nutrition classes. Twelve questions addressing healthy eating knowledge and behavior were administered at baseline, after intervention, and at three months follow-up. After intervention, daily fruit consumption improved from baseline (mean (s.d.) =1.42 (0.55)) to post intervention (mean (s.d.) =1.72 (0.70)) ( p < 0.05) and to three months follow-up (mean(s.d.) =1.94 (0.83)) ( p > 0.05). After intervention, daily vegetable consumption improved from baseline (mean (s.d.) =1.67 (0.59)) to post intervention (mean (s.d.) =1.97 (0.74)) ( p < 0.05) and to three months follow-up (mean (s.d.) = 2.19 (0.82)) ( p > 0.05). Younger construction apprentices showed better healthy eating knowledge at post intervention and three months follow-up ( p > 0.05). Working in normal hours showed better healthy eating knowledge at post intervention but not at three months follow up ( p > 0.05). Both age groups and working hours did not show significant differences on healthy eating behaviour. Nutrition education implemented as a three-hour session within skill courses may possibly promote fruit and vegetable consumption among construction apprentices. Further research with control group is required to support the findings in this study.

Objective: To evaluate the effects of Ving Tsun (VT) sticking-hand training on upper-limb joint position sense and muscular performance in community-dwelling middle-aged and older adults., Methods: Thirty-three adults were randomly allocated to either a VT group or a control group. The VT group received VT sticking-hand training twice per week for 3 months. Measurements were taken before and after the intervention period. The primary outcome was elbow-joint repositioning error, which was measured by an elbow-joint passive positioning and active repositioning test using a universal goniometer. Secondary outcomes were upper-limb muscles' peak force and time taken to reach peak force as measured by a hand-held dynamometer., Results: No significant time, group or time-by-group interaction effects were found for elbow-joint repositioning error or upper-limb muscle peak force outcomes. Shoulder flexor time to peak force decreased by 33.8% from pre-test to post-test in the VT group ( P  = 0.007). Shoulder abductor, internal and external rotator, and elbow extensor times to peak force decreased by 30.0%-35.9% in the VT group ( P  < 0.05) and by 30.4%-37.1% in the control group ( P  < 0.05)., Conclusions: VT sticking-hand training does not improve elbow-joint position sense or the maximum strength of upper-limb muscles in middle-aged and older adults. However, VT can improve shoulder flexor muscles' time to reach peak force in these populations. VT had no obvious effect on the time required to reach peak force in other shoulder muscles and elbow extensors., Competing Interests: The authors declare no conflicts of interest., (© 2020 Chinese Nursing Association.

Background: Adaptive balance control is often compromised in children with developmental coordination disorder (DCD). Neuromuscular training (NMT) is commonly used in clinical settings to improve neuromuscular control and hence balance performance in these children. However, its effectiveness has not been proven scientifically. This randomized controlled study aimed to explore the effectiveness of NMT for improving adaptive balance performance and the associated leg muscle activation times in children with DCD., Methods: Eighty-eight children with DCD were randomly assigned to the NMT or control group (44 per group). The NMT group received two 40-minute NMT sessions/week for 3 months, whereas the control group received no intervention. The outcomes were measured at baseline and 3 and 6 months. The primary outcome was the sway energy score (SES) in both the toes-up and toes-down conditions as derived using the Adaptation Test (ADT). Secondary outcomes included the medial gastrocnemius, medial hamstring, tibialis anterior and rectus femoris muscle activation onset latencies during ADT, measured using surface electromyography and accelerometry. Data were analyzed using a repeated measures analysis of covariance based on the intention-to-treat principle., Results: At 3 months, no significant within-group or between-group differences were noted in the SESs for either group. At 6 months, the toes-down SES decreased by 6.8% compared to the baseline value in exclusively the NMT group (P = .004). No significant time, group or group-by-time interaction effects were observed in any leg muscle activation outcomes., Conclusions: Short-term NMT failed to improve adaptive balance performance and leg muscle activation times in children with DCD. Further studies should explore the clinical applications of longer-term task-specific interventions intended to improve the adaptive balance performance of these children.

Objective: The Pain Catastrophizing Scale (PCS) measures three aspects of catastrophic cognitions about pain-rumination, magnification, and helplessness. To facilitate assessment and clinical application, we aimed to (a) develop a short version on the basis of its factorial structure and the items' correlations with key pain-related outcomes, and (b) identify the threshold on the short form indicative of risk for depression., Design: Cross-sectional survey., Setting: Social centers for older people., Participants: 664 Chinese older adults with chronic pain., Measurements: Besides the PCS, pain intensity, pain disability, and depressive symptoms were assessed., Results: For the full scale, confirmatory factor analysis showed that the hypothesized 3-factor model fit the data moderately well. On the basis of the factor loadings, two items were selected from each of the three dimensions. An additional item significantly associated with pain disability and depressive symptoms, over and above these six items, was identified through regression analyses. A short-PCS composed of seven items was formed, which correlated at r=0.97 with the full scale. Subsequently, receiver operating characteristic (ROC) curves were plotted against clinically significant depressive symptoms, defined as a score of ≥12 on a 10-item version of the Center for Epidemiologic Studies-Depression Scale. This analysis showed a score of ≥7 to be the optimal cutoff for the short-PCS, with sensitivity = 81.6% and specificity = 78.3% when predicting clinically significant depressive symptoms., Conclusions: The short-PCS may be used in lieu of the full scale and as a brief screen to identify individuals with serious catastrophizing.

The study aimed to investigate Chinese adults' nutrition label literacy in Hong Kong. It employed a web-based survey with structured questions. A total of 368 Chinese adults aged 18-59 participated in the survey and their nutrition label literacy was measured by the Newest Vital Sign (NVS). About two-thirds (68%) of the participants had limited nutrition literacy skills. Although they were able to identify correctly the calorie and sugar content of food products, 44% and 48% of them had difficulty in determining the consumption of calories and serving food sizes respectively. Another finding from the survey was that those with lower education level and of older age had significantly lower mean nutrition label literacy scores, which indicated that they were at higher risk for food insecurity. The findings showed that the nutrition label literacy level of Hong Kong's general public is quite low. This study can provide insights for nurses and healthcare professionals on how to educate people with lower education level and/or of advanced age to use nutrition labels more effectively and to further nutrition label literacy study and research, particularly in Hong Kong., (© 2018 John Wiley & Sons Australia, Ltd.)

Background: Hand hygiene prevents cross-infection and is the most effective defense against contagious diseases. Preschoolers, without proper hand hygiene skills, are a vulnerable group to such diseases. The aim of this study was to evaluate whether hand hygiene compliance training of preschoolers in Hong Kong improves their hand hygiene knowledge and performance, and whether the training reduces their absenteeism resulting from influenza symptoms., Methods: This was a quasi-experimental study with a pretest-posttest design. A total of 110 preschoolers participated in a program consisting of 4 training sessions on hand hygiene. Before and after the program, their hand hygiene knowledge was assessed by 10 true or false questions, and their handwashing skills were assessed by photos of their hands taken before and after handwashing. Before handwashing, a fluorescent stain gel was used to cover their hands. To determine whether a causal relationship existed between compliance and absenteeism, the preschoolers' absenteeism data were collected during a period of 3 months for analysis., Results: Significant differences were found in hand hygiene knowledge on handwashing steps, duration, and after playing with toys. Percentage increases were recorded for 8 questions. There was significant improvement in hand hygiene performance on the fronts and the backs of fingers, thumbs, and fingertips (P < .05). The findings showed a decrease in absence rates with influenza symptoms for the month before (31%), during (30%), and after (25%) the completion of the program in all participating schools., Discussion: After the training program, the participants' hand hygiene knowledge and performance considerably improved. They washed their hands more thoroughly and there was a significant reduction in absences owing to influenza., Conclusions: Good cooperation between schools and families is found to be important in helping students build positive attitudes and habits, even in performing simple routines like hand hygiene., (Copyright © 2018.

Construction workers undertake demanding physical work and face high risk of injuries in poor working environments. This case-control study investigated the extent of their musculoskeletal pain incidence at work. A total of 2021 construction workers in different trades were interviewed on-site in a survey from December 2017 to December 2018. The survey results revealed that the pain prevalence of the subjects in the last 24 h was 10.6 %. The worst and top most common pain spots caused by work were central lower back, left/right shoulders, and knees. Regarding pain management, their most common method was to ignore the pain (21.4%). The average percentage of pain relief after receiving treatment in the 24 h was 37.12%. Besides, significant differences were found between the pain and non-pain groups regarding their employment duration in current job or their average sleep duration in the 24 h. The study showed that those with multiple and bilateral pain sites had pain interference on their living activities.

Background: The demand for more creative and innovative nurses and together with the rapid expansion of nurse education in Mainland China have called for new approaches to student learning. Challenge Based Learning, an active student-directed approach was incorporated into an elective course in an undergraduate nursing programme. Initially, the students were given some big ideas about the real world. They worked together in small groups to identify the most challenging problems from these ideas, develop some innovative solutions, formulate an action plan for a selected solution, carry out the actions and evaluate the outcome., Objectives: To evaluate the effectiveness of Challenge Based Learning on students' creativity and innovativeness., Design: Quasi-experimental., Settings: A medical university in Guangzhou, China., Method and Participants: A convenience sample of 48 undergraduate nursing students from the bilingual class, who enrolled in the elective course, Innovation and Creative Thinking was invited to participate in the evaluative study. They completed the Creativity and Innovation Effectiveness Profile before and after the course., Results: Apart from descriptive statistics, the mean scores of the Creativity and Innovation Effectiveness Profile between the pretest and posttest assessments were analyzed using the Wilcoxon signed ranks test. The results showed that the mean scores of all 7 domains (i.e. creative consciousness, levels of curiosity, pattern breaking skills, idea nurturing ability, willingness to experiment and take risks, courage and resilience and energetic persistence) of Creativity and Innovation Effectiveness were significantly higher in the posttest., Conclusion: Students can enhance their ability to innovate and create through learning. The successful practical experience of using CBL in the study provides a good reference for nurse teachers who want their students to be self-directed, creative and innovative., (Copyright © 2018 Elsevier Ltd.

This study compared the shoulder muscular performance and lean mass between elite and recreational swimmers.Thirty elite swimmers (mean age ± standard deviation = 23.1 ± 3.5 years) and 21 recreational swimmers (mean age ± standard deviation = 20.8 ± 2.1 years) participated in the study. Maximum muscle strength and time to maximum muscle strength of shoulder flexor, extensor, abductor, and adductor muscles were measured using a handheld dynamometer. Lean mass of the arms and body (excluding the head) were measured using dual-energy x-ray absorptiometry (DXA).Results revealed that compared with recreational swimmers, elite swimmers had higher maximum muscle strength of the shoulder flexor, extensor, abductor, and adductor muscles (all P < .001). The time to reach maximum muscle strength of all shoulder muscles showed no significant difference between the 2 groups (P > .05). The lean mass values in the left arm (P = .037), right arm (P < .001), and whole body (P = .014) were higher in elite swimmers than recreational swimmers.Elite swimmers had greater shoulder maximum muscle strength compared with recreational swimmers though the time taken to reach maximum muscle strength was similar between the 2 groups. Elite swimmers also showed a higher lean mass in both arms and their entire body when compared with recreational swimmers. The results may be useful for recreational swimmers who intend to advance to professional level, and for talent identification and early development of elite swimmers.

Self-efficacy has been consistently found to be a protective factor against psychological distress and disorders in the literature. However, little research is done on the moderating effect of self-efficacy on depressive symptoms in the context of chronic pain. This cross-sectional study aimed to examine if pain self-efficacy attenuated the direct relationship between pain intensity and depressive symptoms, as well as their indirect relationship through reducing the extent of catastrophizing when feeling pain (moderated mediation). 664 community-dwelling Chinese older adults aged 60-95 years who reported chronic pain for at least three months were recruited from social centers. They completed a battery of questionnaires on chronic pain, pain self-efficacy, catastrophizing, and depressive symptoms in individual face-to-face interviews. Controlling for age, gender, education, self-rated health, number of chronic diseases, pain disability, and pain self-efficacy, pain catastrophizing was found to partially mediate the connection between pain intensity and depressive symptoms. Furthermore, the relationship between pain intensity and depressive symptoms was moderated by pain self-efficacy. Self-efficacy was also found to moderate the relationship between pain intensity and catastrophizing and the moderated mediation effect was confirmed using bootstrap analysis. The results suggested that with increasing levels of self-efficacy, pain intensity's direct effect on depressive symptoms and its indirect effect on depressive symptoms via catastrophizing were both reduced in a dose-dependent manner. Our findings suggest that pain self-efficacy is a significant protective factor that contributes to psychological resilience in chronic pain patients by attenuating the relationship of pain intensity to both catastrophizing and depressive symptoms., Competing Interests: The authors have declared that no competing interests exist.

Background: Volleyball digging techniques may cause pelvic injuries among female volleyball athletes. Pelvic padding and Kinesiology Taping (KT) may reduce impact force and pain and improve posture during a fall. This study examined the effects of pelvic padding and KT on pain perception, fall kinematics, and kinetics among female volleyball athletes., Methods: Twenty-four female volleyball athletes were exposed to two pelvic padding scenarios (with and without padding) and two KT conditions (with and without KT applied on the rectus abdominis muscle) during a fall in the forward direction. The maximum impact force during landing and maximum acceleration of the pelvis were registered using a force platform and an accelerometer, respectively. The maximum lumbar (hyper) extension angle, forward reach distance, and total fall time were measured by video analysis. Pain level was quantified using a visual analog scale., Results: The application of pelvic padding (with and without KT) reduced pain when compared to the no padding condition (p < 0.008). Applying KT alone reduced forward reach distance when compared to the 'pelvic padding and KT' condition (p < 0.010). In fact, when both pelvic padding and KT were applied, participants reached further when compared to the 'no pelvic padding and no KT' condition (p < 0.001). No significant main and interaction effects were found in all other outcomes., Conclusions: Volleyball shorts with pelvic pads are recommended for female volleyball athletes to reduce pain in the digging maneuver and may help to increase their forward reach distance. However, KT is not recommended as it reduces the forward reach distance and cannot reduce pain or improve fall kinematics and kinetics., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Purpose: A deterioration in bone strength and balance performance after breast cancer treatment can result in injurious falls. Therefore, interventions need to be developed to improve the bone strength and balance ability of breast cancer survivors. This cross-sectional exploratory study aimed to compare the bone mineral density (BMD), balance performance, balance self-efficacy, and number of falls between breast cancer survivors who practiced qigong, breast cancer survivors who did not practice qigong, and healthy individuals., Methods: The study included 40 breast cancer survivors with more than 3 months of qigong experience, 17 breast cancer survivors with no qigong experience, and 36 healthy controls. All the participants underwent dual-energy X-ray absorptiometry scans to measure their lumbar spine, total hip, femoral neck, and total radius BMDs. The participants also underwent a timed one-leg stand test to measure their single-leg standing balance. The participants' balance self-efficacy was assessed using the activities-specific balance confidence scale, and the number of falls experienced by each participant was assessed in a face-to-face interview., Results: The lumbar spine, total hip, femoral neck, and total radius BMDs were similar between the 3 groups ( P > .05). The breast cancer-qigong group outperformed the breast cancer-control group by 27.3% when they performed the one-leg stand test on a foam surface ( P = .025), and they also had a higher balance self-efficacy score ( P = .006). Nevertheless, the numbers of falls were comparable between the 3 groups ( P > .05)., Conclusion: Qigong may be a suitable exercise for improving the balance performance and balance self-efficacy of breast cancer survivors.

Background: Studies have shown that physical interventions and psychological methods based on the cognitive behavioral approach are efficacious in alleviating pain and that combining both tends to yield more benefits than either intervention alone. In view of the aging population with chronic pain and the lack of evidence-based pain management programs locally, we developed a multicomponent intervention incorporating physical exercise and cognitive behavioral techniques and examined its long-term effects against treatment as usual (i.e., pain education) in older adults with chronic musculoskeletal pain in Hong Kong., Methods/design: We are conducting a double-blind, cluster-randomized controlled trial. A sample of 160 participants aged ≥ 60 years will be recruited from social centers or outpatient clinics and will be randomized on the basis of center/clinic to either the multicomponent intervention or the pain education program. Both interventions consist of ten weekly sessions of 90 minutes each. The primary outcome is pain intensity, and the secondary outcomes include pain interference, pain persistence, pain self-efficacy, pain coping, pain catastrophizing cognitions, health-related quality of life, depressive symptoms, and hip and knee muscle strength. All outcome measures will be collected at baseline, postintervention, and at 3 and 6 months follow-up. Intention-to-treat analysis will be performed using mixed-effects regression to see whether the multicomponent intervention alleviates pain intensity and associated outcomes over and above the effects of pain education (i.e., a treatment × time intervention effect)., Discussion: Because the activities included in the multicomponent intervention were carefully selected for ready implementation by allied health professionals in general, the results of this study, if positive, will make available an efficacious, nonpharmacological pain management program that can be widely adopted in clinical and social service settings and will hence improve older people's access to pain management services., Trial Registration: Chinese Clinical Trial Registry, ChiCTR-IIR-16008387. Registered on 28 April 2016.

Background: This single-blinded, three-armed randomized controlled trial aimed to compare the effects of postexercise ice-water immersion (IWI), room-temperature water immersion (RWI), and no water immersion on the balance performance and knee joint proprioception of amateur rugby players., Methods: Fifty-three eligible amateur rugby players (mean age ± standard deviation: 21.6 ± 2.9 years) were randomly assigned to the IWI group (5.3 °C), RWI group (25.0 °C), or the no immersion control group. The participants in each group underwent the same fatigue protocol followed by their allocated recovery intervention, which lasted for 1 minute. Measurements were taken before and after the fatigue-recovery intervention. The primary outcomes were the sensory organization test (SOT) composite equilibrium score (ES) and the condition-specific ES, which were measured using a computerized dynamic posturography machine. The secondary outcome was the knee joint repositioning error. Two-way repeated measures analysis of variance was used to test the effect of water immersion on each outcome variable., Results: There were no significant within- and between-group differences in the SOT composite ESs or the condition-specific ESs. However, there was a group-by-time interaction effect on the knee joint repositioning error. It seems that participants in the RWI group had lower errors over time, but those in the IWI and control groups had increased errors over time. The RWI group had significantly lower error score than the IWI group at postintervention., Conclusion: One minute of postexercise IWI or RWI did not impair rugby players' sensory organization of balance control. RWI had a less detrimental effect on knee joint proprioception to IWI at postintervention.
