- Neck strength variations in dental students with and without neck pain : a longitudinal studyPublication . Almeida, Manuel Barbosa; Moreira, Marion; Moleirinho-Alves, Paula; Oliveira, RaúlNeck pain can induce specific motor responses and alterations in muscle strength. Therefore, this study aimed to investigate and compare the progression of cervical muscle strength within and between students with and without neck pain over the course of their first semester of clinical training. We used an online Nordic Musculoskeletal Questionnaire for group allocation, and neck strength in flexion, extension, and lateral flexion on both sides was measured using the KForce Bubble Pro hand-held dynamometer. Forty-four students were divided into neck pain (n = 21) and asymptomatic (n = 23) groups. Both groups increased neck strength by the end of the semester in flexion, extension, and left and right lateral flexion (p < 0.001). Students experiencing neck pain showed a significantly lesser degree of improvement (p = 0.036) in right lateral flexion. The agonist/antagonist ratios revealed an enhanced role of neck extensors across both groups. Dental students showed overall increased cervical strength in their first semester of clinical training. Those with neck pain exhibited a diminished rate of strength gain in right lateral flexion when compared with students without pain by the semester’s end, suggesting different neuromuscular adjustments to clinical practice in students experiencing pain, which may lead to functional impairments in later training stages.
- Patient-reported outcome measures in knee injuries rehabilitation : a protocol for interventionPublication . Moreira, José; Mesquita, Marina; Flamínio, José; Almeida, Manuel Barbosa; Delgado, Bruno; Boto, PauloDifferent musculoskeletal conditions affect people all over the world and were considered by the WHO to be the main cause of disability in 4 of 6 regions in 2017, with an increase in the associated burden and the impact they have on today's society. One of these conditions is related to the knee, which is associated with complex and vulnerable injuries associated with ligaments, menisci, and cartilage. After surgery, there is a reflex inhibition of motor neurons and immobilization, there is rapid atrophy and weakness in the different associated muscles, affecting proprioception, strength and muscle function, compromising quality of life. The aim of this article is to describe a protocol for a rehabilitation program after surgery for people with knee injuries. An experimental study will be carried out with 75 patients, with control and experimental groups. In both groups, initial measurements will be compared with measurements after the program, at different times. It is hoped that this study will generate significant information on rehabilitation intervention for people with knee injuries.
- Prevalence of musculoskeletal disorders among dental students : a systematic review and meta-analysisPublication . Almeida, Manuel Barbosa; Póvoa, Rita; Tavares, Duarte; Alves, Paula Moleirinho; Oliveira, RaúlObjectives: This study aimed to determine the prevalence of work-related musculoskeletal disorders (WMSDs) in dental students and analyze the potential associated risk factors. Methods: 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). Results: 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. Conclusions: 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.
