Arthroscopic shoulder stabilisation surgery (ASSS) is a common procedure for treating anterior shoulder instability. Postoperative rehabilitation remains a crucial, but under-researched, aspect of patient recovery. Despite its importance, no comprehensive rehabilitation guideline based on robust clinical trials has emerged, leaving a gap in evidence-based practice.To address this, the British Elbow & Shoulder Society appointed the Allied Health Professional Clinical Guideline Group to review current practices and establish clinical guidance on rehabilitation. This evidence synthesis aims to provide a critical synthesis and discussion on rehabilitation following ASSS. The intended outcome is to highlight areas of uncertainty and make recommendations for clinical practice and further research.The development of this evidence synthesis followed a rigorous five-stage process: (1) systematic literature review, (2) UK national practice survey, (3) expert consensus (Delphi) study, (4) updated literature search and review and (5) synthesis of the previous four stages. Stages 1-3 have been published previously. This evidence synthesis comprised stages 4 and 5.10 key domains for postoperative rehabilitation from immediate postsurgery to return to normal function, including sports, were identified. This paper synthesises current knowledge and provides a platform for recommendations in clinical practice and future research. In particular, early shoulder movement was recommended during the 'immobilisation period', but confined to shoulder elevation up to 90°, anterior to the scapular plane, with neutral external rotation. Further high-quality primary research is needed to address uncertainties and expand the evidence base, thereby informing and challenging clinical practice.

The aim of this review was to evaluate the current evidence regarding the impact of sleep deprivation (SD) on strength performance. An English-language literature search revealed 514 articles through primary database searches, and 563 via organization searches/citation searching. The inclusion criteria were met by thirteen articles which were included in the review. The inclusion criteria set were healthy male and/or female adult participants, a sleep loss condition (e.g. SD or partial sleep deprivation), strength measures (e.g. back strength or leg strength or grip strength), and a peer-reviewed academic paper counterbalanced and/or or randomised in design. The systematic review identified a total of 13 studies that met the inclusion criteria. Some studies reported a negative impact of SD on strength performance, while others showed no significant differences following a night of SD. Both acute and chronic SD were found to result in some measures of muscle strength, power output, and muscular endurance to be significantly reduced. Additionally, impaired neuromuscular function and increased fatigue were commonly observed in sleep-deprived individuals. The findings of this systematic review highlight the detrimental effects of SD on strength performance. Individuals involved in strength-based activities should prioritize adequate sleep to optimize their physical performance. Further research is needed to explore the underlying mechanisms linking SD and strength impairment, as well as to investigate potential interventions to mitigate these effects. Sleep hygiene education and interventions targeting sleep duration and quality should be implemented to promote optimal strength and performance outcomes. Future research should focus on understanding the mechanisms behind these effects and developing effective interventions to mitigate the adverse consequences of SD on muscle function.

IntroductionTotal and sub-total lesions of the anterior cruciate ligament (ACL) are one of the most frequent and performance-limiting injuries to the knee joint within the active population. Early surgical management, often regarded as the primary management strategy, has recently been shown to have similar outcomes when compared with an initial rehabilitative approach followed by surgical ACL reconstruction if higher levels of functionality are needed. The primary objective of the study was to investigate the physiotherapists and orthopedic surgeons’ “coper/non-coper” screening application in the clinical management of the patient after ACL injury. Second, the authors aimed to investigate the cooperation between physiotherapists and orthopedic surgeons when dealing with patients with ACL injuries.MethodsAn online survey consisting of 12 questions on the clinical practice of the surveyed physiotherapists (n = 803) and orthopedic surgeons (n = 201), and the relation between these healthcare professionals, was distributed. The answers were stratified depending on clinical experience in dealing with ACL injuries.ResultsBoth physiotherapists and orthopedic surgeons showed a low degree of confidence and application of the “coper/non-coper” screening when managing ACL lesions. The sub-population of ACL experts reported a good level of interprofessional interaction. Nevertheless, an updated level of knowledge regarding the recent evidence on the non-surgical management of ACL lesions is still lacking.ConclusionsThe study findings indicate the need to improve the collaboration between Italian physiotherapists and orthopedic surgeons as well as their knowledge of the non-surgical approaches to ACL lesions.

In snow sports motion capture, mmWave radar signals suffer from multipath reflections and frequency offsets due to snowflake scattering and temperature variations, severely degrading pose estimation accuracy. To address this, we propose a cascaded anti-interference framework composed of adaptive MTI filtering, genetic sparse array optimization, and hybrid carrier tracking. These physical-layer enhancements are followed by a spatiotemporal 3D CNN–LSTM network for motion decoding and a multimodal Kalman-particle filter for trajectory fusion. Experimental validation in both simulation and real-world snow environments confirms the framework’s robustness. Compared to baseline systems, the proposed method reduces the joint positioning root mean square error (RMSE) by up to 72%, enhances angular velocity tracking precision by 72%, and improves signal-to-noise ratio (SNR) by 24.3 dB. The end-to-end processing delay remains under 26 ms, ensuring real-time deployment. These results demonstrate significant improvements in accuracy, robustness, and real-time performance under harsh environmental interference, offering a viable solution for mmWave-based motion capture in snowy sports scenarios.

Sensorimotor processing is a fundamental neurodevelopmental skill that underpins many higher order cognitive abilities. Early ethnic differences in motor behaviour have been found. However, the reported disparities have involved subjective measures and can be explained via differences in socioeconomic status or cultural biases. For the first time, to our knowledge, we were able to investigate ethnic population differences longitudinally with objective kinematic measures of sensorimotor processing. Sensorimotor processing was investigated in 1340 children from the ‘Born in Bradford’ cohort. Data were collected at two timepoints (age 4–5 years and 7–9 years). Even after controlling for socioeconomic differences, the Pakistani-heritage population demonstrated quantitatively lower levels of sensorimotor processing relative to children of White British heritage at both timepoints. These differences were equivalent to six months’ developmental progress. However, ethnic differences decreased over time. The decreases over time suggest that sensorimotor skill deficits can be mitigated through education and daily learning activities. Our findings suggest sensorimotor measures can provide a behavioural marker of neurodevelopmental status and have potential for identifying children who need early learning support. The ethnic differences are not well explained by socioeconomic factors, with genetic and environmental differences providing a potential hypothesis for future testing.
