The study compared superficial trunk muscle activity and postural control among an active extension subgroup of people with nonspecific chronic low back pain (AE-NSCLBP) with painfree controls during functional tasks. Thirty-two people (17 people with low back pain [LBP] and 15 painfree controls) participated in this study. Muscle activity of 5 trunk muscles and postural control were investigated during both standing tasks (eyes open/closed; single/double-leg balance) and dynamic functional tasks (spinal forward flexion and return, and a sit to stand transfer). Results showed that during single-leg standing, people with AE-NSCLBP exhibit higher muscle activity than painfree controls for 3 trunk muscles, especially with their eyes closed. There were no significant differences in muscle activity between eye conditions during double-leg standing and sit to stand transfer, forward flexion, and return from flexion. The AE-NSCLBP subgroup also demonstrated significantly impaired postural control (lower time to boundary) in 4 of 8 conditions, especially during single-leg standing and with their eyes closed. These findings show people with LBP typically demonstrated greater trunk muscle activity and poorer postural control while maintaining standing posture. This pattern was most evident when the postural challenge was higher, such as single-leg standing or with eyes closed. While this study design cannot infer causality, these findings have implications for LBP rehabilitation, particularly regarding approaches which seek to alter muscle activation among people with LBP.

Purpose: To investigate the impact of eastward travel across 7 time zones on sleep, jet lag, and recovery in elite soccer athletes. Methods: Twenty-one male and 20 female athletes (21.5 [1.7] y) traveled from Ireland to Taiwan to represent their national team at the World University Games 2017. Daily monitoring via actigraphy and subjective sleep and well-being measures were obtained for 1 week in Ireland (baseline), and for the duration of an international soccer tournament (days 1–5 [precompetition] and days 6–18 [competition]). Results: Sleep duration (P =.028) and time in bed (P =.006) were significantly lower at precompetition compared with baseline. Sleep quality (P <.001) was significantly decreased in precompetition compared with baseline and competition. Subjective jet lag symptoms continued for up to 13 days posttravel. Athletes reported significantly greater fatigue during precompetition compared with competition (P =.005); however, there were no significant differences for recovery (P =.35) and readiness to train (P =.35). Sleep hygiene changed significantly during precompetition and competition compared with baseline in relation to reduced electronic device use (P =.005) and reduced caffeine intake (P <.001). Females reported significantly greater presleep tension–anxiety compared with males at all timepoints (P =.02). Conclusion: Long-haul eastward travel across 7 time zones has a significant impact on sleep duration and quality, likely related to changes in sleep patterns and jet lag. Athletes report changes in sleep hygiene posttravel; however, sleep remained negatively impacted for up to 5 days. Despite significant sleep disturbance and jet lag symptoms, young healthy athletes appear to recover well from long-haul travel; however, it is unknown if this interferes with training and competition performance.

The six-minute walk test (6MWT) can assess walking function but is time-consuming. We investigate the correlation of performance over the first two minutes of the 6MWT (2MWT#) and the 6MWT. We also evaluate the 2MWT#'s ability to predict 6MWT results, assess correlations to secondary explanatory outcomes, and assess the ability to discriminate between clinical subgroups. A cross-sectional study of 124 participants with LBP. Correlations between the 2MWT# and 6MWT and secondary outcomes were evaluated using the Pearson product-moment correlation coefficient. The predictive ability of the 2MWT# was defined as the residual distance between the observed 6MWT and three times the 2MWT#. Differences between clinical subgroups were evaluated using the Wilcoxon rank test. The 2MWT# and 6MWT correlated highly (r = 83, 95% CI 0.76 − 0.87). The 2MWT# overestimated 6MWT results with 46.8 meters (SD 67.0). Both tests correlated with secondary outcomes and discriminated similarly between clinical subgroups. The 2MWT# correlates highly with 6MWT but overestimates the observed 6MWT by 9%. Because it is shorter, possibly less burdensome, and with little or no loss of discriminatory ability, we consider it a legitimate alternative to the 6MWT in patients with LBP. Walking function is often affected in patients with low back pain (LBP). The six-minute walk test (6MWT) is frequently used to assess walking function but is time-consuming. A shorter two-minute walk test is a legitimate alternative in patients with LBP as it correlates highly with the 6MWT and has little or no loss of discriminatory ability between clinical subgroups.

Objective: The study explores the attitudes of people with chronic health conditions towards the use of group-based telerehabilitation. Design: A qualitative research study. Setting: The setting involved semi-structured focus groups via videoconferencing software. Participants: A purposive sample of 18 people with chronic health conditions including cardiorespiratory, neurological and musculoskeletal conditions was recruited via national patient advocacy and support groups in Ireland and clinical contacts. The sample included both those who had, and had not, previously engaged in telerehabilitation programmes. Procedures: An online questionnaire collected demographic information and data regarding previous telerehabilitation participation and telerehabilitation preferences. Focus groups were conducted using videoconferencing software, in accordance with the Consolidated Criteria for Reporting Qualitative Research (COREQ) Checklist, and analysed using thematic analysis following Braun and Clarke's methodology. Findings were triangulated with quantitative questionnaire data. Results: Four focus groups were conducted including participants with chronic cardiorespiratory (n = 8), neurological (n = 6) and musculoskeletal (n = 4) conditions. Three themes were identified regarding telerehabilitation: (a) benefits and facilitators (including convenience, increased service accessibility, social connection and technological support), (b) challenges and barriers (including technological access and literacy, limited 'hands-on' therapy, safety concerns and social limitations), and (c) preferences (regarding mode of delivery, content, duration and generic programmes for mixed-condition groups). Conclusions: Telerehabilitation is convenient for people with chronic conditions; however, concerns exist regarding the use of technology and the limitations of this healthcare delivery method. The role of telerehabilitation is valued, and future programmes should acknowledge patient preferences including a hybrid model of care, exercise and educational content, social interaction and synchronous components.

AbstractPurposeMaterial and methodsResultsConclusionIndividuals with Low Back Pain (LBP) often face significant disabilities, including walking limitations. We use the Two-Minute Walk Test (2MWT) to assess walking performance, comparing overground and treadmill versions for correlation and interchangeability.A randomised cross-over study of 40 participants with LBP randomly completed the 2MWT in a hallway and on a treadmill. The correlation was analysed by the Spearman Rho correlation coefficient (r), the agreement by the Bland-Altman method, differences between the testing orders by a paired sample t-test, and the association by a univariate regression.A high correlation was found between the methods (r = 0.76, p < 0.01). The difference between the methods was 45.4 metres (95% CI 33.4: 57.4, p < 0.01) or 29%, with an insignificant 6.8 metres (95% CI −17.4: 31.0, p = 0.57) between the testing orders. Notably, the distance walked in the hallway served as a strong predictor, explaining a substantial portion of the variation observed in the distance covered on the treadmill (R2 = 0.61, p < 0.01).Performance of the 2MWT overground and on a treadmill correlate highly in people with LBP. However, because participants walked 29% further in the hallway, treadmill walking is likely not an interchangeable alternative to testing when the aim is to evaluate performance.

Objective: To highlight the necessity for on-going vigilance of serious pathology when assessing and managing people with spinal pain. Methods: A case report of a young male patient who sought physiotherapy treatment for his acute thoracic pain. Following physiotherapy assessment, it seemed unlikely that the pain was related to a musculoskeletal problem. Besides pain-induced vomiting, there were no overt signs of serious pathology. However, he had a family history of cardiac issues. The patient was referred back to his general practitioner (GP) for further assessment. Results: The patient was subsequently diagnosed with perimyocarditis following investigations and was treated accordingly. At 6, 12 and 24 months follow-up, he reported good health. Conclusions and impact statement: Physiotherapists must remain vigilant of serious pathology even if patients have been examined by other healthcare professionals. This case also raises the issue of whether 'vascular profiling' should be part of routine practice protocols. [ABSTRACT FROM AUTHOR]

We evaluated the effects of Cognitive Behavioural Therapy (CBT) alone or with additional interventions on pain, disability, kinesiophobia, anxiety, stress, depression, quality of life, and catastrophizing of patients with chronic neck pain (CNP). Nineteen studies met the inclusion criteria, and fourteen studies were quantitatively analysed. Risk of bias was assessed using the PEDro scale and the certainty of evidence using the GRADE approach. Studies were pooled (where applicable) and subgroup analyses were performed for CNP, or whiplash associated disorders. Studies compared—directly or indirectly—CBT interventions to no treatment, conservative interventions such as exercise and/or physiotherapy, or multimodal interventions. We present effect estimates at 8-week, 12-week, 6-month, and 1-year follow-up. Low certainty evidence suggests a clinically significant pain reduction (short-term) favouring CBT with or without additional intervention compared to no intervention SMD = −0.73; 95%CI: −1.23 to −0.23). Very low and low certainty evidence suggest clinically significant improvements in kinesiophobia (very short-term SMD = −0.83; 95%CI: −1.28 to −0.39 and short-term SMD = −1.30, 95%CI: −1.60 to −0.99), depression SMD = −0.74, 95%CI: −1.35 to −0.14) and anxiety SMD = −0.76, 95%CI: −1.34 to −0.18) favouring a multimodal intervention with CBT (short-term) compared to other conservative interventions. Combining different types of CBT interventions resulted in potentially heterogeneous comparisons. [ABSTRACT FROM AUTHOR]
