Background: A psychometric study of the Family Adaptability and Cohesion Scale (FACES III) has been conducted in Spanish-speaking countries from the perspective of the classical test theory. However, this approach has limitations that affect the psychometric understanding of this scale. Objective: Accordingly, this study used the item response theory to investigate the psychometric performance of the items. Furthermore, it evaluated the differential performance of the items for Colombia and Chile. Method: For this purpose, 518 health science students from both countries participated. Confirmatory Factor Analysis was used. Results: The study results revealed that the cohesion and adaptability items presented adequate discrimination and difficulty indices. In addition, items 5, 8, 13, 17, and 19 of cohesion indicated differential functioning between students from both countries, with Chilean students exhibiting a greater discriminatory power. Further, the Colombian group exhibited a greater discriminatory power for item 18 of adaptability. Conclusions: The study concluded that the items of FACES III indicated adequate psychometric performance in terms of their discriminative capacity and difficulty in Chile and Colombia.

Objetivo: este estudio se propuso investigar los efectos combinados del ejercicio físico y la educación en el manejo del dolor, implementados mediante telerehabilitación, en mujeres con fibromialgia. Método: Se llevó a cabo un estudio experimental de pre y post test, con veintiún participantes con fibromialgia asignadas al grupo intervención (n=11) y un grupo control (n=10) que mantuvo sus tratamientos habituales. La intervención comprendió 24 sesiones de ejercicios de fuerza y resistencia. Adicionalmente, se realizaron sesiones semanales de educación en dolor. Se emplearon herramientas de evaluación, como FIQR, SF-MPQ, PCS y SATED. Resultados: En el grupo de intervención se observaron mejoras significativas en la funcionalidad física y la gravedad de los síntomas (p = 0,023), además de una reducción significativa en la catastrofización (p = 0,007). En contraste, el grupo control no mostró cambios significativos (p > 0,05). Conclusiones: La combinación de ejercicio y educación a través de la telerehabilitación demostró beneficios notables en la funcionalidad física, la sintomatología y la reducción de la catastrofización en mujeres con fibromialgia. Estos resultados respaldan la eficacia de las intervenciones no farmacológicas integrales y destacan la relevancia de la telerehabilitación como una opción valiosa en el manejo de esta condición. La reducción significativa en la catastrofización sugiere que este enfoque integral podría influir positivamente en la percepción del dolor y la calidad de vida de las personas con fibromialgia. Palabras claves: ejercicio - fibromialgia - educación en salud - telerrehabilitación Objective: This study aimed to investigate the combined effects of physical exercise and pain management education, implemented through telerehabilitation, in women with fibromyalgia. Method: A pre-post experimental study was conducted with twenty-one fibromyalgia participants assigned to the intervention group (n=11) and a control group (n=10) maintaining their usual treatments. The intervention consisted of 24 strength and resistance exercise sessions. Additionally, weekly pain education sessions were conducted. Evaluation tools such as FIQR, SF-MPQ, PCS, and SATED were employed. Results: In the intervention group, significant improvements in physical functionality and symptom severity were observed (p = 0.023), along with a substantial reduction in catastrophizing (p = 0.007). In contrast, the control group showed no significant changes (p > 0.05). Conclusions: The combination of exercise and education through telerehabilitation demonstrated notable benefits in physical functionality, symptomatology, and catastrophizing reduction in women with fibromyalgia. These results support the efficacy of comprehensive non-pharmacological interventions and underscore the relevance of telerehabilitation as a valuable option in managing this condition. The significant reduction in catastrophizing suggests that this comprehensive approach could positively influence pain perception and the quality of life of individuals with fibromyalgia. Keywords: exercise - fibromyalgia - health education - telerehabilitation.

Wearable inertial sensors have become tools for objectively assessing mobility in older people. This study analyzed whether wearable inertial sensors could detect exercise-induced mobility changes and compared the effects of multicomponent training (MCT) and elastic band training (EBT) on mobility and physical function in older women. Forty-two participants were randomly allocated to either the MCT (n = 21) or EBT (n = 21) group, where 38 (EBT: n = 19; MCT: n = 19) completed the 16-week intervention. Outcomes included instrumented Timed Up-and-Go (iTUG) assessed with a wearable inertial sensor, the Senior Fitness Test, maximal isometric handgrip strength, conventional TUG, anthropometric measurements, health-related quality of life, and blood biomarkers. Data were analyzed using age-adjusted linear mixed-effects models. The iTUG showed shorter completion time (p < 0.001), reduced middle-turn duration (p = 0.004), and increased cadence (p = 0.007). Significant time effects were also observed for chair stand (p = 0.011), arm curl (p < 0.001), and conventional TUG (p = 0.009). No significant group × time interactions were detected. After adjustment for multiple comparisons, no significant changes were observed in anthropometric measures, health-related quality of life, or blood biomarkers. Wearable inertial sensors detected training-related mobility changes, and both exercise programs improved physical function and mobility without between-group differences.

This cross-sectional survey of 85 maintenance workers at a Chilean mining company examined acceptability of industrial exoskeletons. Likert items were analyzed by age group (30 or younger, 31 to 40, 41 or older). Willingness to use was high with device knowledge low. Older workers reported lower expected helpfulness and greater distrust (errors). Musculoskeletal discomfort concentrated in the lower back and upper limbs, consistent with tasks identified for assistance. Open-ended responses highlighted expectations of pain and effort relief, alongside constraints of space, fit, and training. Findings indicate favorable social acceptability with practical gaps for implementation pilots integrated with ergonomic controls.
