Shoulder pain is one of the most common musculoskeletal conditions, and for people over 40 years old, it represents the musculoskeletal pain with the greatest impact on quality of life. Psychological factors, such as fear-avoidance beliefs, are associated with musculoskeletal pain, and several studies suggest that they can influence various treatment outcomes. Our objective was to explore the cross-sectional association between fear-avoidance beliefs and shoulder pain intensity and disability in subjects with chronic shoulder pain. A cross-sectional study was conducted, and 208 participants with chronic unilateral subacromial shoulder pain were recruited. The shoulder pain and disability index assessed pain intensity and disability. The Spanish fear-avoidance components scale assessed the presence of fear-avoidance beliefs. The association between fear-avoidance beliefs and pain intensity and disability was analyzed by means of multiple linear regression models and proportional odds models, reporting odds ratios and 95% confidence intervals. Shoulder and pain disability scores were significantly associated with fear-avoidance beliefs (p < 0.0001, adjusted R-square 0.93, multiple linear regression). There was no evidence of an association between sex and age in this study. The regression coefficient for shoulder pain intensity and disability score was 0.67446. The proportional odds model showed an odds ratio of 1.39 (1.29–1.50) for shoulder pain intensity and disability total score. This study suggests that greater levels of fear-avoidance beliefs are associated with greater levels of shoulder pain and disability in adults with chronic shoulder pain.

This study aims to describe the psychomotor development of children, the offspring of Chilean and Haitian parents, and who attend the local kindergartens. The design of this study was a descriptive and cross-sectional study. The study population was children 3 to 24 months-old, belonging to kindergartens, evaluated with the Psychomotor Development Assessment Scale (EEDP) regarding psychomotor development profile for the domains of language, socialization, coordination, and motor skills. A questionnaire was administered to the parents to determine the socioeconomic level, educational level, and parenting skills. Twenty-four infants, 12 children of Chilean parents, and 12 children of Haitian parents were evaluated. The EEDP classification (p = 0.299) did not show significant differences between both groups. In children of Chilean parents, 25% (3/12) classified as delay, while 75% (9/12) as normal. On the other hand, for children of Haitian parents, 8.3% (1/12) classified as risk, while 91.7% (11/12) as normal. There are significant differences in coordination (p = 0.006), in which Haitian children achieved better performance compared to the Chilean. It is necessary to emphasize every domain of infant psychomotor development and the multiple sociocultural variables that can influence this. Current evaluation methods do not presently have an intercultural character.

Chronic Obstructive Pulmonary Disease (COPD) is a progressive respiratory disorder that poses significant challenges in treatment adherence. This systematic review evaluates the effectiveness of mobile health (mHealth) interventions compared to conventional therapy in improving treatment adherence among COPD patients. A total of 13 randomized controlled trials and comparative cohort studies published up to July 2023 were included, analyzing interventions such as medication reminders and remote monitoring in adult COPD patients. Studies involving participants under 18 years of age or with severe comorbidities were excluded. This review identified 4688 records from MEDLINE, WEB OF SCIENCE, and SCOPUS. Of these, 13 studies met the inclusion criteria. The selection process was conducted by two independent reviewers, with discrepancies resolved by consensus with a third reviewer. The results showed that mHealth interventions improved treatment adherence in some studies, particularly in exercise and symptom monitoring; however, the evidence was inconsistent, and results varied across studies. This review concludes that mHealth interventions have the potential to improve adherence but higher-quality studies and more robust designs are needed to confirm these findings and support their clinical implementation.

Myosteatosis, the infiltration of skeletal muscle by fat, has been studied predominantly in the context of ageing, sarcopenia and functional decline, yet emerging evidence suggests that altered muscle quality may emerge earlier in the life course, particularly among paediatric populations with metabolic risk. Muscle ultrasound is an accessible, non-ionising, portable alternative to computed tomography and magnetic resonance imaging, but its use is methodologically heterogeneous and the biological construct represented by echo intensity remains uncertain. This scoping review aims to map the available evidence on the use of muscle ultrasound to assess myosteatosis and muscle quality across the lifespan, with emphasis on paediatric populations with metabolic risk, and to characterise methodological heterogeneity, analysis and normalisation strategies, the biological validity of ultrasound-derived parameters, and knowledge gaps. The review will follow the JBI methodology for scoping reviews and will be reported using the PRISMA-ScR guidance. Studies of children, adolescents and adults, whether healthy or with metabolic, neuromuscular, neurodegenerative or functional conditions, will be eligible when they report at least one ultrasound-derived measure interpreted as muscle fat infiltration, muscle composition or muscle quality. MEDLINE, Embase, CINAHL, SPORTDiscus, Scopus, Web of Science, the Cochrane Library and LILACS will be searched, together with grey-literature sources and citation searching. References will be managed in Zotero; two reviewers will screen records independently and in duplicate in Rayyan; and data will be charted in a piloted spreadsheet using a verified single-extraction model. Findings will be presented using descriptive numerical analysis, narrative summaries, tables and evidence maps; no meta-analysis and no formal risk-of-bias assessment will be undertaken. The protocol was registered prospectively in the Open Science Framework (registration DOI 10.17605/OSF.IO/MBDHR). The review will provide the first lifespan map of muscle ultrasound for myosteatosis and muscle quality, with particular relevance for resource-limited and Latin American settings.

El Journal Physiotherapy Interventions (JPI) se complace en anunciar su lanzamiento como una nueva revista científica dedicada a la difusión de investigaciones en fisioterapia. En un contexto donde la evidencia científica es fundamental para la práctica clínica, JPI busca consolidarse como un referente en la publicación de estudios que contribuyan al desarrollo y la proyección internacional de la fisioterapia en Chile y Latinoamérica. JPI adopta un modelo de acceso abierto diamante, garantizando la equidad en el acceso al conocimiento sin costos para autores ni lectores. La revista sigue un riguroso proceso de revisión por pares doble ciego y se adhiere a estándares internacionales de publicación, incluyendo las directrices de COPE y EQUATOR Network. Además, cuenta con una estrategia de indexación progresiva que apunta a su inclusión en Latindex, DOAJ, SciELO, Scopus y Web of Science (WoS), maximizando la visibilidad e impacto de las investigaciones publicadas. Finalmente, JPI invita a fisioterapeutas, kinesiólogos e investigadores en ciencias de la rehabilitación a contribuir con estudios de alta calidad que fortalezcan la fisioterapia basada en evidencia y promuevan avances significativos en el ámbito clínico y académico.
