Objective: To investigate the association between adolescents' mobile phone dependence (MPD) and musculoskeletal pain.Methods: A cross-sectional study was conducted among 622 adolescents aged 10–18 in Tabio, Colombia. Participants completed an online survey that included the MPD and the Nordic Musculoskeletal Questionnaire, which assessed musculoskeletal pain symptoms.Results: 56.3% (n = 350) participants reported experiencing musculoskeletal pain, with the upper back being the most affected area (30.4%, n = 193). Adolescents reporting pain had significantly higher MPD scores compared to those without pain (mean 29 vs. 24, p < 0.001). Additionally, females exhibited higher MPD scores than males (mean 29 vs. 25, p < 0.001) and had a higher prevalence of pain (32% vs. 24%). Furthermore, older adolescents in the 11th grade had higher MPD scores than younger adolescents in the 5th grade (mean 31 vs. 21, p < 0.019). Logistic regression analysis indicated that specific MPD dimensions, namely “abuse” and “difficulty regulating use,” were significantly associated with general pain and neck pain, but no association was observed with upper back pain. Furthermore, female sex was linked to both neck and upper back pain.Conclusion: This study found that the MPD dimensions of “abuse” and “difficulty regulating use” were significantly associated with neck pain, regardless of the adolescents' sex.

Objetivo determinar la relación entre exposición a pantallas, comportamiento sedentario y dolor musculoesquelético en adolescentes. Metodología: se realizó una revisión sistemática de artículos en las bases de datos web of science, dimensions, scopus, sciencedirect, clinical key y lens entre agosto 2022 - enero 2023, identificando 150 registros y donde mediante un proceso de selección, se incluyeron 12. Los artículos, debían haberse publicado entre 2017 y enero 2023 en español, inglés o portugués, y relacionar el comportamiento sedentario y tiempo de exposición a pantallas con la presencia de sintomatología dolorosa musculoesquelética en adolescentes, se realizó el cribado de los estudios mediante el software Ryyan con dos evaluadores independientes.Resultados: 12 artículos cumplieron los criterios de inclusión (1 ensayo cruzado, 11 estudios transversales analíticos). La totalidad de los estudios incluidos reportaron alta prevalencia de dolor entre los adolescentes en una o más partes del cuerpo; encontrándose también asociación entre la exposición a pantallas y el comportamiento sedentario. Conclusión: Esta revisión sistemática muestra evidencia sobre la aparición de dolor musculoesquelético en adolescentes, con inicio en edades tempranas, situación que se asocia con la dependencia y exposición a pantallas, así como a bajos niveles de actividad física y altas tasas de comportamiento sedentario. Palabras claves: enfermedades musculoesqueléticas; dolor de cuello; dolor de hombro; dolor de la región lumbar; conducta sedentaria; tiempo de pantalla; adolescente. Objective: to determine the relationship between screen exposure, sedentary behavior, and musculoskeletal pain in adolescents. Methodology: a systematic review of articles in the databases Web of Science, dimensions, Scopus, ScienceDirect, Clinical Key, and Lens was carried out between August 2022 - January 2023, identifying 150 records and through a selection process, 12 were included. The articles had to have been published between 2017 and January 2023 in Spanish, English, or Portuguese, and relate sedentary behavior and screen exposure time with the presence of painful musculoskeletal symptomatology in adolescents. The studies were screened using Ryyan software with two independent evaluators. Results: 12 articles met the inclusion criteria (1 crossover trial, 11 analytical cross-sectional studies). All the included studies reported a high prevalence of pain among adolescents in one or more parts of the body; an association was also found between exposure to screens and sedentary behavior. Conclusion: This systematic review shows evidence of the occurrence of musculoskeletal pain in adolescents, with onset at early ages, a situation that is associated with screen dependence and exposure, as well as low levels of physical activity and high rates of sedentary behavior. Keywords: musculoskeletal disease; neck pain; shoulder pain; low back pain; sedentary behavior; sedentary lifestyle; screen time; adolescent.

The objectives of this study were to determine the effects of the Mézières Method (MM) on pain and disability related to low back pain (LBP), compared to a program of heat, massage and exercise, and to understand the meaning of the bodily experience with the MM. Mixed methods convergent parallel design, combining an equivalent randomized clinical trial with a qualitative phenomenological approach. Sixty-one participants aged 18-65 years with chronic non-specific LBP lasting more than 3 months. Patients were randomized into two groups: the MM group (n = 29) and the comparison group (CG) who received heat, massage plus flexibility and strengthening exercises (n = 31). MM and CG participants underwent 10 one-hour physical therapy sessions over a 5-week period and were evaluated three times: pre-intervention, post-intervention and follow-up at 6 weeks after the end of treatment. Both groups reported positive effects on LBP . MM group showed superior effects in pain relief in the short term (Cohen's D 0.80; p = 0.004). Participants interpreted the interaction with the MM as a teaching-learning process that allowed body awareness. Both treatment were similarly beneficial but MM had superior effects on pain in the short term. MM is perceived by the participants as a teaching-learning process focused on body awareness that facilitate effective management of LBP.

Introduction. The Objective Structured Clinical Examination (OSCE), an evaluation instrument, requires a validation process to guarantee the measurement of skills related to clinical reasoning. The OSCE is relevant for decision making during the formation process for professional practice. Objective. To determine the content validity and inter-rater reliability of an OSCE during a physiotherapy undergraduate programme for clinical reasoning. Materials and Methods. Instrumental design, which identified content validity through internal consistency (Cronbach’s alpha), added to recognition of the inter-rater reliability (intraclass correlation coefficient). Results. The instrument demonstrates good internal consistency and a degree of agreement from substantial to almost perfect. Conclusions. The OSCE proved a suitable instrument to assess the clinical reasoning skill in physiotherapy students; nevertheless, this validation process has limitations in the number of stations and in not having sufficient application to physiotherapy.
