Ítem Beliefs about low back pain in physiotherapy students(Federacion Espanola de Docentes de Educacion Fisica, 2023) Carvajal-Parodi, Claudio; Ojeda, Camilo; Silva, Tomás; Mendoza, Cristhian; Valdés, Andrés Riveros; Guede-Rojas, FranciscoLow back pain is a global health problem, and its level of disability depends, among other variables, on patients' negative beliefs regarding pain. Evidence supports that these beliefs are associated with those held by their treating professionals, so it is important to identify how they evolve during the undergraduate training of health professionals. This cross-sectional study aimed to determine the presence of negative beliefs about low back pain in physical therapy students and compare them between different courses of the training cycle. Second, to fifth-year physiotherapy students from a Chilean university participated; they completed a survey based on Deyo's seven myths about low back pain and responded according to their degree of agreement with the statements. The results were compared between the different levels. 127 students completed the survey (57 males and 70 females). Myths 1, 2, 4, 6, and 7 were presented more frequently in the second year and tended to decrease progressively in higher grades. Myths 3 and 5 presented a less clear distributional pattern. Second-level students presented a higher degree of agreement with the myths, and third-level students presented greater insecurity in the answers. In contrast, fourth and fifth-level students presented greater disagreement with the myths. In conclusion, negative beliefs about low back pain may be present in physical therapy students, but these tend to modify positively throughout their formative process. © Copyright: Federación Española de Asociaciones de Docentes de Educación Física (FEADEF).Ítem Dolor musculoesquelético y discapacidad del cuadrante superior en estudiantes de instrumentos de cuerda: Un estudio piloto transversal(Federacion Espanola de Docentes de Educacion Fisica, 2024-06) Jara, Ornella Cheuquel; Alegría, Jetzabel Rodríguez; Carvajal-Parodi, Claudio; Arias-Álvarez, Gonzalo; Mendoza, Cristhian; Soto-Martínez, Adolfo; Guede-Rojas, FranciscoAntecedentes: El dolor musculoesquelético (DME) es prevalente en los músicos y se localiza principalmente en el cuadrante superior, afectando la funcionalidad. Los movimientos repetitivos, el tipo de instrumento, la edad y el sexo condicionan este comportamiento, entre otros factores. Si bien la evidencia es limitada, pareciera ser que los músicos de cuerdas se encuentran dentro de quienes más frecuentemente reportan dolor y discapacidad de origen musculoesquelético. Objetivo: Caracterizar el DME y el nivel de discapacidad en el cuadrante superior asociado a la práctica de instrumentos de cuerda en estudiantes de conservatorio. Método: En este estudio piloto observacional de corte transversal, se aplicaron seis instrumentos de evaluación autoreportados a 14 estudiantes de cuerdas (8 hombres y 6 mujeres) de diferentes instrumentos (violín, viola, guitarra clásica, violoncello y contrabajo): Quick Dash Global (QDG) y de Alto Rendimiento/Músicos (QDL), Índice de Discapacidad Cervical (NDI), Escala de Graduación de Dolor Crónico (EGDC), el Cuestionario de Dolor Neuropático (DN4 abreviado) y el Mapa Corporal de Dolor (body chart). Resultados: El 100% de la muestra presentaba DME al momento de la evaluación, mayoritariamente de baja intensidad, siendo en el 21.42% de los casos de carácter crónico y diseminado. El 64.28% presentaba dolor neuropático. La funcionalidad general medida con EGDC se encontraba afectada en el 71.42% de los individuos. La funcionalidad del miembro superior presentó un QDG medio de 16.4 ±15.63 y un QDL medio de 32.11 ±16.78, mientras que a nivel cervical el 64.28% presentó discapacidad de leve a moderada medida con NDI. Conclusión: El DME y la discapacidad en el cuadrante superior son condiciones frecuentes en estudiantes músicos cordófonos. Futuros estudios deberán profundizar en las causas e indagar en estrategias eficientes para prevenir estas afecciones a lo largo de su proceso de formación.Ítem Effects of Active Video Games Combined with Conventional Physical Therapy on Perceived Functionality in Older Adults with Knee or Hip Osteoarthritis: A Randomized Controlled Tria(Multidisciplinary Digital Publishing Institute (MDPI), 0025-01) Guede-Rojas, Francisco; Mendoza, Cristhian; Fuentes-Contreras, Jorge; Alvarez, Cristian; Agurto Tarbes, Bárbara; Muñoz-Gutiérrez, Javiera Karina; Soto-Martínez, Adolfo f; Carvajal-Parodi, ClaudioBackground: Osteoarthritis (OA) leads to functional decline in older adults. This study aimed to evaluate the effectiveness of active video games (AVGs) as a complement to conventional physical therapy (CPT) in improving functional disability. Methods: Sixty participants were randomly assigned to an experimental group (EG, n = 30, 68.7 ± 5.4 years), which received CPT combined with AVGs, or to a control group (CG, n = 30, 69.0 ± 5.5 years), which received CPT alone. Sessions were performed three times a week for ten weeks. Functional disability was assessed using the WOMAC index before, during, and after the intervention. Secondary outcomes included the Global Rating of Change (GRoC), the Minimal Clinically Important Difference, and patient trajectories through functional disability strata. Results: The EG showed progressive improvements in all WOMAC scores, with moderate to large increases by the end of the intervention, while the CG only showed significant changes in the later stages. The EG demonstrated greater improvements in WOMAC pain and the GroC scale (p < 0.05), maintaining most of the gains at follow-up, whereas the CG showed regression. Additionally, the EG had a higher proportion of responders, particularly for pain, while the CG had a predominance of non-responders and adverse responders. In the EG, 70% improved their functional disability stratification compared to 50% in the CG. Conclusion: Integration of AVGs with CPT further improves perceived functional disability in older adults with OA. Future research should explore these findings further. © 2024 by the authors.Ítem Effects of Active Video Games Combined with Conventional Physical Therapy on Perceived Functionality in Older Adults with Knee or Hip Osteoarthritis: A Randomized Controlled Trial(Applied Sciences (Switzerland), Volume 15, Issue 1January 2025 Article number 93, 2025) Guede-Rojas, Francisco; Mendoza, Cristhian; Fuentes-Contreras, Jorge; Alvarez, Cristian; Agurto Tarbes, Bárbara; Muñoz-Gutiérrez, Javiera Karina; Soto-Martínez, Adolfo; Carvajal-Parodi, ClaudioBackground: Osteoarthritis (OA) leads to functional decline in older adults.

Repetitive movements, type of instrument, age, and sex influence this behavior, among other factors. Although the evidence is limited, it seems that string players are among those who most frequently report pain and disability of musculoskeletal origin. Objective: To characterize MSP and the level of upper quadrant disability associated with stringed instrument playing in conservatory students. Methods: In this cross-sectional observational pilot study, six self-reported assessment instruments were applied to 14 string students (8 males and six females) of different instruments (violin, viola, classical guitar, cello and double bass): Quick Dash Global (QDG) and High Performance/Musicians (QDL), Neck Disability Index (NDI), Chronic Pain Grading Scale (EGDC), the Neuropathic Pain Questionnaire (abbreviated DN4) and the Body Map of Pain (body chart). Results: 100% of the sample presented MSP at the time of the evaluation, mostly of low intensity, being in 21.42% of the cases of chronic and disseminated character. Neuropathic pain was present in 64.28% of cases. General functionality measured with EGDC was affected in 71.42% of the individuals. Upper limb functionality presented a mean QDG of 16.4 ±15.63 and a mean QDL of 32.11 ±16.78, while at the cervical level, 64.28% presented mild to moderate disability measured with NDI. Conclusion: DME and upper quadrant disability are frequent conditions in chordophone student musicians. Future studies should deepen the causes and investigate efficient strategies to prevent these conditions throughout their training process. © 2024 Federacion Espanola de Docentes de Educacion Fisica.

Aim: To assess the perceived cognitive function and cognitive performance in women with FM. Material and Methods: Cross-sectional study including 100 women with FM (FMG) and 100 healthy controls (CG). Self-perceived cognitive functioning was evaluated using the Functional Assessment of Cancer Therapy Cognition scale (FACT-Cogv3). The neuropsychological performance was assessed with the Trail Making Test (TMT-A, TMT-B), Digit Span test (DS), Barcelona test (DS-F/B) and the Frontal Assessment Battery (FAB-E), Spanish version test. Results: The mean scores of all cognitive self-perception factors and all neuropsychological tests were lower in the FMG (p < 0.001). Over 90% of the FMG took longer than the population mean (P50) to complete the TMT-A and TMT-B tests, while in the CG, 1/3 took longer than the P50 in both tests. The minimum expected scores for the DS-F and DS-B tests were not achieved by 40 and 9% of FMG participants, respectively. According to FAB-E, 54% and 24% of FMG were categorized as fronto-subcortical deficit and fronto-subcortical dementia, respectively. Conclusions: Women with FM have a higher perception of cognitive dysfunction and lower cognitive performance in objective tests than healthy women. More research is needed to explore the clinical, psychosocial, and sociodemographic characteristics that predispose to cognitive deficits in this group of patients. © 2022 Sociedad Medica de Santiago.
