Objective: Upright positions in the second stage of labour are recommended by many international organizations. However, they have not been widely used worldwide, especially in China. One of the important factors is the absence of a practice programme based on the best available evidence. We thus developed a Practice Programme for Upright Positions in the Second Stage of Labour following the UK Medical Research Council framework. Under the guidance of the programme, whether the use of upright positions can improve the maternal birth experience is a question of great concern. This study aimed to explore the birth experience of Chinese women who adopted upright positions in the second stage of labour., Design: This qualitative descriptive study was conducted as part of an implementation study that developed an evidence-based intervention and used strategies to integrate the evidence-based intervention into routine obstetric clinical practice., Setting: The maternity department of a tertiary comprehensive hospital in Hebei Province, China., Participants: Semi-structured interviews with twelve eligible women who adopted upright positions in the second stage of labour were conducted between March and April 2022. Qualitative data were analyzed by using conventional content analysis., Findings: The average age of included women was 26.5 ± 3.5 years, and ten of them were primiparous women. Eight women adopted epidural analgesia during labour to relieve labour pain. All women gave birth in at least one type of upright position in the passive second stage of labour and adopted the semi-recumbent position in the active second stage of labour. Through conventional content analysis, we found that the use of upright positions in the second stage of labour could possibly promote an overall positive birth experience. Women giving birth in upright positions generally perceived they were more involved in their birthing process, and had greater physical and mental capacity to cope with childbirth., Key Conclusions: Women have a positive birth experience when using upright positions in the second stage of labour., Implications for Practice: This study suggests upright positions could improve women's birth experience and have the potential to be widely applied in clinical practice., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

Purpose: To evaluate the influence of body posture change on the peripherally inserted central catheter tip position in Chinese cancer patients., Methods: A prospective observational trial was conducted in a tertiary cancer hospital from August to September 2018. After the insertion of peripherally inserted central catheter, chest X-ray films were taken to check the catheter tip in the upright and supine positions, respectively. The distance from the carina to the catheter tip was separately measured on both chest films by nurses. The primary study outcome was the distance and direction of the catheter tip movement. The secondary study outcome was to analyze the influence factors on the catheter tip movement. The third study outcome was to observe the related adverse events caused by the catheter tip movement., Results: A total of 79 patients were included, the results showed that 61 moved cephalad, 14 moved caudally, and 4 did not move with body change from the supine to the upright position. When moved cephalad, the mean distance was 19.34 ± 11.95 mm; when moved caudally, the mean distance was -15.83 ± 8.97 mm. The difference between the two positions was statistically significant ( p  < 0.001). There was also a statistically significant difference between catheter tip movement direction and body mass index ( p  = 0.009) and height ( p  = 0.015). Two patients developed arrhythmias; no cardiac tamponade was found due to body posture change., Conclusion: The results of this work implied that the tips of the catheter tend to shift toward the cephalad with body change from the supine to the upright position. A study involving a larger sample size is needed to find more information in the future.

Introduction: The aim of this study was to pilot Relaxbirth® (Relaxbirth®, Ltd., Helsinki, Finland), an investigational device designed to facilitate upright positioning intrapartum. The objective was to 1) compare birth outcomes with and without the use of Relaxbirth®, and 2) assess device usability., Methods and Materials: Study design: prospective product use and retrospective case control study at one perinatal center in Ohio., Inclusion Criteria: ≥18 years old, <300 lbs. women with a low-risk, term gestation of a singleton, vertex fetus, and vaginal birth between January 2013 to June 2016. Participants who used the Relaxbirth® device intrapartum (RB group) were retrospectively case-matched to controls (CON group) according to age, race, insurance, gravida/parity, gestational age and labor type. Birth outcomes (primary outcome) were compared between groups. Providers and women who used Relaxbirth® assessed usability of the device with the Modified System Usability Scale Tool (secondary outcome)., Results: Of the n = 60 included in the final analysis, RB women (n = 30) pushed for a shorter average duration compared to CON women (n = 30) [34 min (±48) versus 60 min (±63), p = 0.023]. RB women did not experience more adverse birth outcomes including: longer second stage duration, operative vaginal delivery, malpresentation, perineal laceration/episiotomy, higher blood loss, or low Apgars. Usability survey results were favorable (Total Average Scores: providers 74.1; RB 83.6)., Conclusion: Clinical experience with the Relaxbirth® device was positive at this pilot site. The device was associated with favorable birth outcomes and usability, suggesting potential as a safe and novel adjunct to promote intrapartum choices, upright positioning and maternal satisfaction., (Copyright © 2018 Elsevier Masson SAS.

Problem: Despite research evidence supporting use of upright birthing positions, most women give birth in supine position. Little is known about women's knowledge and use of labour and birthing positions. Specifically, there is a lack of evidence on Malawi women's knowledge and use of birthing positions, and this limits the possibility of improvement in childbirth practices., Aim: To assess women's knowledge and use of different positions during labour and birthing., Methods: The study used a cross-sectional descriptive survey in a Malawi maternity unit where 373 low-risk postnatal women participated in face-to-face exit interviews, using a structured questionnaire. A descriptive analysis of the categorical variables was conducted to examine frequencies and percentages., Findings: The majority of women knew about walking (66.4%) and lateral (60.6%) as labour positions, whereas 99.2% knew about the supine as a birthing position. Half of the women (50%) walked during labour and the majority (91.4%) gave birth whilst in supine position. Midwives were the main source of information on positions used during childbirth., Discussion: Education about different birthing positions is needed for women who deliver at the maternity unit so that they can make informed decisions on their own options for childbirth. However, midwives must have the competence to encourage and assist women give birth in different positions, so professional development of midwives in childbirth positions is a priority., Conclusion: Childbirth education should include information on the various labour and birthing positions. Midwives should be equipped with appropriate skills to help women use different positions during childbirth., (Copyright © 2016 Australian College of Midwives. Published by Elsevier Ltd.

Intravenous injection is the most feared medical procedure and gives rise to an experience of mild to severe pain in children. Unrestrained pain has a negative effect on the child. Pain management in the form of a convenient sitting position is needed by children who undergo intravenous injection procedures. This study aims to determine the effect of parental holding and an upright position on children's pain during intravenous injection procedures. The study used the Randomized Clinical Trial method involving 34 respondents, aged 1-4 years, who were included in the intervention and control group. The result of a Mann-Whitney U test analysis showed a significant difference in the pain score between the intervention and control groups (p value = .000; α = .05). The parental holding and upright position can be applied as a nonpharmacological pain management strategy for children who undergo intravenous injection procedures.

Neuroimaging researchers tacitly assume that body-position scantily affects neural activity. However, whereas participants in most psychological experiments sit upright, many modern neuroimaging techniques (e.g., fMRI) require participants to lie supine. Sparse findings from electroencephalography and positron emission tomography suggest that body position influences cognitive processes and neural activity. Here we leverage multi-postural magnetoencephalography (MEG) to further unravel how physical stance alters baseline brain activity. We present resting-state MEG data from 12 healthy participants in three orthostatic conditions (i.e., lying supine, reclined at 45°, and sitting upright). Our findings demonstrate that upright, compared to reclined or supine, posture increases left-hemisphere high-frequency oscillatory activity over common speech areas. This proof-of-concept experiment establishes the feasibility of using MEG to examine the influence of posture on brain dynamics. We highlight the advantages and methodological challenges inherent to this approach and lay the foundation for future studies to further investigate this important, albeit little-acknowledged, procedural caveat.

Introduction and Hypothesis: The aim of this study was to evaluate the role of the maternal position at the time of delivery on the onset of de novo symptoms of urinary incontinence (UI) in the post-partum period., Methods: This prospective study evaluated the data of consecutive women undergoing labour and delivery, between January 2014 and July 2014. We included only women with a singleton pregnancy undergoing vaginal delivery. During the study period, patients chose to deliver in the position that they considered the most comfortable. The onset of UI was evaluated according to the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-sf)., Results: Overall, 716 primiparous women were included in the study. Sixty women refused the 12-week post-partum interview (8.4%). Women were divided in two groups: 296 women (45.1%) who chose an upright position during delivery (group 1) and 360 women (54.9%) who chose a supine position (group 2). Group 1 had a significantly lower episiotomy rate, but a higher rate of greater than second degree perineal tears. In group 1 we found a significantly lower rate of de novo UI (40.5% vs 48.9%, p = 0.03) and in particular of stress urinary incontinence. Via multivariate analysis, birth position was the only factor correlating with the occurrence of urinary incontinence in the post-partum period (OR: 1.52; 95%CI: 1.06, 2.18; p = 0.02)., Conclusions: Upright positions at delivery are related to a lower episiotomy rate and a higher rate of greater than second degree perineal tears. Supine positions are an independent risk factor for the onset of de novo UI.

Facial surgeries are usually performed with the patient in the supine position; however, it is crucial to predict postoperative results in the upright position. This study aimed to clarify the posture-related morphological changes in the facial soft tissue regarding age and sex, using physical measurements to obtain results in specific linear metric measurements of standard facial features. One hundred healthy volunteers were divided into four groups based on age and sex (25 young men, 25 young women, 25 old men, 25 old women). For all participants, 18 measuring points were marked on the skin along with 18 paired linear measurements, and the angle was measured using a digital sliding caliper and angle meter in both upright and supine positions. In all four groups, the intercanthal width (en-en), binocular width (ex-ex), length of the eye fissure (en-ex), length of the nasal bridge (n-prn), width of the nose (al-al), height of the lower face (sn-gn), vermilion height of the lower lip (sto-li), height of the lower lip (sto-sl), width of the philtrum (cphi-cphi), width of the mouth (ch-ch), and nasolabial angle (NLA) were significantly larger in the supine position than in the upright position. The increase was larger in the older age groups than in the younger age groups. Moreover, the increase was larger in old men than in old women. During facial surgery involving these areas, surgeons should consider the patient's age and sex and understand what facial figuration change would occur depending on posture and change their preoperative design or make minor adjustments during operation in the supine position to increase patient satisfaction.

Background/aims: The World Health Organization encourages women in labour to ambulate and assume upright positions shown to be associated with favourable childbirth outcomes. However, the literature shows that most women in developed and developing countries, including Malawi, give birth in the supine position. There is a lack of research on factors that influence choice of birthing positions among women in Malawi. This study aimed to identify these factors. Methods: A face-to-face descriptive survey was conducted on 373 low-risk postnatal women in Malawi. Bivariate and multivariate analyses were used to determine association between sociodemographic characteristics and choice of labour and birthing position, as well as to identify predictive factors. Results: Walking during labour was significantly associated with age (P=0.018) and monthly family income (P=0.012). During birth, women who had received some degree of education were more likely to use the supine position than those who had not (93% vs 78%; P=0.011). However, women with a higher level of income were less likely to use the supine position than women with low income (82% vs 93%; P=0.005). Conclusions: Age, income and education influence Malawian women's choices for labour and birthing position. There is a need for Malawian women to be informed about and encouraged to use different labour and birthing positions, regardless of their socioeconomic and demographic status, to promote positions that improve maternal and neonatal outcomes. Childbirth education sessions or classes during antenatal care should include information on different birthing positions. [ABSTRACT FROM AUTHOR]

Bipedal walking is a composite task requiring integration of many control circuitries in the brain and spinal cord. The present study was carried out to verify whether an increase in blood lactate, such as that associated with a high intensity exercise, is able to significantly modify the qualitative and/or quantitative aspects of human walking. Eighteen healthy physically male participants, aged between 20 and 24 years (M = 21.8, SD = 1.22), were recruited for the study. For this purpose, the experimental protocol included the measure of blood lactate levels with the aim of assessing possible relations between lactate blood values and different aspect of walking after an exhaustive exercise. An exhaustive exercise was associated with a strong increase of blood lactate levels and produced a significant worsening in the ability to maintain the bipodalic upright posture as well as the fluidity of walking. Our results suggest that exhausting bouts impose greater challenges on postural control.

Background The heels are one of the most common sites of pressure ulcers, and the incidence rate in the elderly aged 70 years or older is high. Although there is literature on heel interface pressure, the heel interface pressure of the elderly in different postures has not yet been explored, which will be investigated in this study, as well as the effects of different foot positions. Their skin conditions will also be examined. Methods Twenty-five females and twenty-six males, 70 years old or older, are evaluated while lying down, with only their naked foot in its natural position on a mattress, as well as placed on a standard or pressure-relieving mattress in different positions. The moisture, sebum content, and elasticity of the skin of the heel are tested. Findings The heel of most of the participants is positioned at a 60°–69° or 90°–99° angle to the support surface. The heel interface pressure is the greatest when the foot is upright. The age, weight, and body mass index have no significant impacts. The moisture and sebum content are extremely low while elasticity is normal. Interpretation The relaxed position of the foot is in neutral external rotation and upright positions. A greater amount of pressure is experienced when the foot is upright. The pressure-relieving mattress is more effective for reducing heel pressure but may not apply to all cases. Finally, the skin of the heel is dry and lacks sebum, which implies greater risk of developing heel sores. [ABSTRACT FROM AUTHOR]

The aim of this study was to test the hypothesis that, in comparison with standard postures, aero posture (AP) would modify the coordination of lower limb muscles during pedalling and consequently would influence the pedal force production. Twelve triathletes were asked to pedal at an intensity near the ventilatory threshold (VT+Δ20%) and at an intenisty corresponding to the respiratory compensation point (RCP). For each intensity, subjects were tested under three positions: (1) upright posture (UP), (2) dropped posture (DP), and (3) AP. Gas exchanges, surface electromyography and pedal effective force were continuously recorded. No significant difference was found for the gas-exchange variables among the three positions. Data illustrate a significant increase [ gluteus maximus (GMax), vastus medialis (VM)] and decrease [ rectus femoris (RF)] in electromyography (EMG) activity level in AP compared with UP at RCP. A significant shift forward of the EMG patterns (i.e. later onset of activation) was observed for RF (at VT+Δ20% and RCP), GMax, VL, and VM (at RCP) in AP compared with UP. These EMG changes are closely related to alteration of force profile in AP (higher downstroke positive peak force, lower upstroke negative peak force, and later occurrence of these peaks along the crank cycle).

Upright positions during the second stage of labour are assumed to have many physiological advantages that may facilitate normal birth. Clarifying the underlying benefits and risks of upright positions plays an important role in the implementation of upright positions. The benefits and risks of upright positions during the second stage of labour have been explored in several systematic reviews, but the results are divergent. To summarize the evidence on the underlying benefits and risks of upright positions during the second stage of labour by searching available systematic reviews to explore the best evidence for clinical practice and decision making. Overview of systematic reviews. We systematically searched five English databases and four Chinese databases from inception to 15th March 2020 for any published and ongoing systematic reviews. Two reviewers independently evaluated the methodological and the reporting quality of the included systematic reviews using the AMSTAR 2 tool and the PRISMA checklist. A descriptive synthesis was used by reporting the results of the highest quality reviews. Seven systematic reviews met the eligibility criteria, of which two Cochrane reviews had the highest methodological and reporting quality. In women without epidural analgesia, upright positions significantly reduced the rate of instrumental vaginal birth (moderate-quality evidence), shortened the second stage of labour (very low-quality evidence), reduced the rate of episiotomy (very low-quality evidence) and abnormal foetal heart rate patterns requiring intervention (very low-quality evidence), but significantly increased the risk of blood loss greater than 500 ml (moderate-quality evidence) and second-degree perineal trauma (low-quality evidence). However, no definite benefits or risks of upright positions were found in women with epidural analgesia based on the current evidence. This overview demonstrates that upright positions have both benefits and risks but the quality of the current evidence is relatively low. It is necessary for the researchers to conduct robust studies to provide stronger evidence. In addition, upright positions are recommended to be used depending on women's preferences and labour progress, but should also be carefully monitored especially in women with epidural analgesia.
