This study aimed to determine the prevalence of work-related musculoskeletal disorders (WMSDs) in dental students and analyze the potential associated risk factors. This review was registered in PROSPERO with the number CRD42022349864. We performed a meta-analysis calculating event rates with relative 95% confidence intervals for each body region. Two investigators systematically searched Cochrane, Pubmed, Scopus, and EBSCO databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Sixteen studies, with 3761 dental students, were included. The highest 7-day prevalence was in the lower back (27.2%; 95% CI 20–35), neck (27%; 95% CI 19.1–35.8), and upper back (24.2%; 95% CI 17.2–32). Yearly occurrence was mainly in the neck (51%; 95% CI 41–61), followed by shoulders (45.3%; 95% CI 37.6–53.1) and lower back (42%; 95% CI 34.1–50.2) and a fraction of these reported that symptoms in lower-back (15.2%; 95% CI 12.1–18.5), neck (13.9%; 95% CI 10.6–17.5) and shoulders (12.2%; 95% CI 8.7–16.3) affected work or normal activities. Associated contributing factors include female sex, poor posture habits, inadequate ergonomics knowledge, sedentary lifestyle, high physical activity levels, poor quality of life, and smoking. In contrast, engaging in physical exercise has positively impacted mitigating the risk of musculoskeletal disorders. WMSDs have a high prevalence among dental students, particularly in the cervicothoracic, lumbar, and shoulder regions, having a significant impact since training years. Further research with a multidimensional approach with psychosocial and physical assessments is recommended to understand this issue thoroughly.

Health professionals like physiotherapists require additional choices in portable dynamometers to conduct evaluations pre- and post-intervention in order to accurately measure the efficacy of treatments and patient progression and to adjust rehabilitation goals. New dynamometers have arrived on the market, but there is no evidence for performance of the Kinvent. This study aimed to investigate intra- and inter-rater reliability (ICC one-or-two-way-random-model/Bland–Altman) of the Kinvent hand-held dynamometer in the muscle groups of the lower and upper limbs (COSMIN guidelines). The Kinvent showed a good to excellent intra- and inter-rater reliability for almost all the upper and lower limbs movements assessed. Ankle dorsiflexion was moderate in all assessments.

Irish dance is growing in popularity, evolving to a more athletic and demanding dance style. The aim of this study is to conduct a systematic review, previously registered with PROSPERO, to identify the prevalence, incidence, and the injury pattern among Irish dancers and analyse the associated risk factors. Six online databases and two dance-specific science publications were searched systematically. Studies were included if the patterns of injuries among Irish dancers were evaluated or the factors associated with injury were analysed, published in English or Portuguese, in peer-reviewed scientific journals. Four reviewers assessed the quality and level of evidence using the Downs and Black criteria and a modified Oxford Centre of Evidence-Based Medicine 2009 model, respectively. Eleven articles were included, eight of Level 3c (cross-sectional) and three of Level 3b (prospective). Mean DB percentage score was 63% ± 7.2%. Prevalence ranged from 72.2% to 92.6%, affecting mostly the foot/ankle complex. Only two articles reported incidence, which ranged from 3.4 to 10.6 injuries/1000 h danced depending on injury definition. Psychological factors, elite level, and insufficient/poor sleep were associated with musculoskeletal injury. Injury prevalence and incidence is high in Irish dancers, with the foot and ankle being more affected. Due to heterogeneity in injury definitions, methods, and populations, along with the need for improvement in studies quality, recommendations were made for future research.

Background: Irish dance is growing in popularity, evolving to a more athletic and demanding dance style. Aims: To conduct a systematic review, previously registered with PROSPERO, to identify prevalence, incidence, and injury pattern among Irish dancers and analyse associated risk factors.
