RESUMO
The measurement of isometric muscle torque with hand-held dynamometry is a technique little studied in the pediatric setting for the evaluation of maximal isometric muscle strength. OBJECTIVE: to determine the reliability of hand-held dynamometry to obtain the maximal isometric torque of upper and lower limb muscle groups in Chilean children and adolescents. PATIENTS AND METHODS: Crosssectional study. Seventy-two participants aged between 7 and 15 years were selected from a school in Talca. Maximal isometric torque was recorded in 15 muscle groups of upper and lower limbs through hand-held dynamometry. Intra- and inter-rater evaluation was used, applying the intraclass correlation coefficient (ICC) to determine the reliability of the tests and Bland-Altman plots to evaluate concordance. RESULTS: The results demonstrated good to excellent inter-rater reliability (ICC = 0.850.98) and intra-rater reliability (ICC = 0.87-0.98). Only two groups, hip extensors and abductors, showed good inter-rater reliability (ICC = 0.85 and ICC = 0.88, respectively); and one group, the ankle dorsiflexors, showed good intra-rater reliability (ICC = 0.87). 100% of the tests presented at least 95.8% inter- and intra-rater agreement on the Bland-Altman plots. CONCLUSION: The evaluation of isometric muscle torque using hand-held dynamometry is a reliable procedure for use in different growth periods.

BACKGROUND: COVID-19 confinement measures in the population affected the quality of life and sleep. AIMS: To determine if confinement is associated with a lower quality of life and sleep. SUBJECTS AND METHODS: A self-reported survey including questions about type of confinement, time spent in front of a screen, the international physical activity questionnaire (IPAQ), the Sleep Self Report questionnaire and the SF-36 quality of life survey, was answered by 621 Chilean university students. RESULTS: Confined and not confined respondents spent a great amount of time in front of a screen, in sedentary activities and sleeping > 8 or < 6 hours per day. Those who were in confinement reported having a poorer quality of sleep and quality of life compared to those who were not in confinement. Those who required mandatory confinement for suspected COVID-19 had the worst quality of sleep and quality of life. CONCLUSIONS: University students had sedentary lifestyles regardless of the type of confinement. Those who were in confinement, especially for suspected COVID-19 infection, had the worst quality of sleep and quality of life.

BACKGROUND: Upper limb (UL) function is compromised in university students due to prolonged academic activities and excessive use of electronic devices. However, it is unknown whether this relationship was affected by the COVID-19 pandemic situation. AIM: To determine the risk factors associated with reduced UL functionality in university students in a pandemic situation due to COVID-19. MATERIAL AND METHODS: Cross-sectional study that included 621 university students from the northern, central and southern areas of Chile. Physical variables, musculoskeletal, anthropometric and sociodemographic history were evaluated through self-reported questionnaires. RESULTS: The factors with the higher association with a lower UL functionality were pain (Odds ratio (OR) = 17.6; 95% confidence intervals (CI) = 5.2-60; p < 0.01) and injury (OR = 10.4; 95% CI = 3.9-28.3; p < .001). Also, a low weight (OR = 10.5; 95% CI = 2.2-49.6; p < 0.01) and a quarantine lasting for five or more weeks (OR = 9.1; 95% CI = 1,1-77.2; p = 0.043) were considered risk factors. The lower probability was observed in male participants (OR = 0.2; 95% CI = 0.1-0.51; p < 0.01) and in those with a moderate/high muscular condition (OR = 0.3; 95% CI = 0.1-0.9; p = 0.031. CONCLUSIONS: The identification of these modifiable risk factors can help to implement preventive or rehabilitative actions at home or universities.

Antecedentes: Estudios recientes refieren que los pacientes con dolor crónico sufren cambios en el procesamiento de la información que les llega desde la periferia con el solo hecho de cambiar el orden en que los estímulos les son ejercidos, por ejemplo, cuando se les cruzan las manos. En los pacientes con dolor crónico se ha demostrado la presencia de alteraciones en sus marcos de referencia somatotópicos, y es por esto que la estrategia de cruzar las extremidades por la línea media, podría generar cambios en la percepción dolorosa. Objetivo: Evaluar si un programa de fisioterapia analgésica aplicada con cruce de manos es más eficaz que uno sin el cruce para disminuir el dolor. Material y método: 16 pacientes con dolor crónico de codo, muñeca o mano ingresaron al estudio. Fueron aleatorizados en un grupo experimental, que recibió la aplicación de electroanalgesia nerviosa transcutánea (TENS) con cruce de manos y ojos cerrados, además de un grupo control, que recibió solo electroanalgesia. A cada grupo se les evaluó su dolor pre y postintervención, con el cuestionario del dolor de McGill y la escala visual análoga (EVA). Resultados: Ambos grupos, el control y experimental, presentaron una disminución en el dolor postintervención; el grupo control disminuyó una media de 3,5 cm y el grupo experimental con una media de 3,75 cm. Todas las sesiones del grupo experimental fueron estadísticamente significativas (p < 0,05), mientras que el grupo control presentó una sesión no estadísticamente significativa (p = 0,051). El análisis de varianza (ANOVA) entre ambos grupos, sin embargo, no dio estadísticamente significativo (p = 0,863). Conclusiones: Los resultados no evidencian convincentemente que el cruce de manos potencia los efectos de la terapia analgésica en relación con la intensidad dolorosa. Más estudios serían necesarios para incluir esta técnica como una estrategia de apoyo en pacientes con dolor crónico, y poder manejar así las alteraciones sensoperceptivas y los cambios en el procesamiento de la información que les llega de la periferia
Background: Recent studies report that patients with chronic pain, they undergo changes in the processing of information that reaches them from the periphery with the mere fact of changing the order in which the stimuli are exercised, for example, when their hands are crossed. In patients with chronic pain, the presence of alterations in their somatotropic frames of reference has been demonstrated, and this is why the strategy of crossing the extremities through the midline could generate changes in the perception of pain. Objective: To evaluate if an analgesic physiotherapy program with hand crossing technique is more effective than a program without crossing hands, in order to reduce pain. Material and method: Sixteen patients with chronic pain in elbow, wrist or hand, were randomized in two groups. One received transcutaneous electrical nerve stimulation (TENS) with hand crossing and closed eyes, and the other (control group) received only the application of TENS. Each group was evaluated before and after the intervention with the McGill pain questionnaire and the visual analog scale (VAS). Results: A decrease in post-intervention pain was observed in both groups; where the control group decreased an average of 3.5 cm and the experimental group 3.75 cm. All sessions of the experimental group were statistically significant (P = <0.05), while one session in the control group was not statistically significant (P = 0.051). However, the Analysis of variance (ANOVA) between both groups, did not give statistically signifi cant (p = 0.863). Conclusions: The results do not show that the crossing of hands potentiates the effects of analgesic therapy on pain intensity. More information is the effects to include this technique as a support strategy in patients with chronic pain, and to manage sensory alterations and changes in the processing of information that reaches the periphery
