Objective: to determine lifestyle changes, such as physical activity, nutrition, and sleep in an Argentinean university population, caused by confinement during the COVID-19 pandemic. Methods: Cross-sectional study via web survey. 1021 the Argentinean university population (women, n = 645 and men, n = 376) aged between 18–70 years old was participate. Survey was utilized to measure participant physical activity behavior, nutrition, and sleep April to May 2020. Results: the main findings revealed that 4.3% of the sample showed obesity; the highest proportion of the sample stayed more than 6 hours in a sedentary status; 21.74% reported bad sleep quality; a reduction in good feeding pattern; and an increase in subjects who do not perform physical activity. According to socio-demographic and anthropometric factors, being a student (OR 2.19, CI95% 1.18 - 4, p= .012), overweight (OR 1.71, CI95% 1.19 – 2.44, p= .003), obesity (OR 4.45, CI95% 2.27 – 8.7, p< .001), and have been confined more than 45 days was associated with bad feeding. Likewise, low physical activity levels were associated with obesity (OR 3.2 CI95% 1.66 – 6.18, p= .001), being female (OR 1.61, CI95% 1.14 –2.28, p= .006) and get married (OR 1.72, CI95% 1.14 – 2.61, p= .009). Moreover, being a student was associated with poor sleep quality (OR 43.6, CI95%5.4 – 350, p< .001). Conclusion: This study suggests that confinement decreased healthy living habits such as good nutrition and physical activity and affected the quality of sleep in young subjects.  Resumen. Objetivo: determinar los cambios en el estilo de vida, como la actividad física, la nutrición y el sueño en una población universitaria argentina, causados por el confinamiento durante la pandemia de COVID-19. Métodos: Estudio transversal mediante encuesta por Internet. Participaron 1021 personas de la población universitaria argentina (mujeres, n = 645 y hombres, n = 376) de entre 18 y 70 años de edad. La encuesta fue utilizada para medir el comportamiento de la actividad física, la nutrición y el sueño de los participantes de abril a mayo de 2020.Resultados: los principales hallazgos mostraron que el 4,3% de la muestra presentaba obesidad; la mayor proporción de la muestra permaneció más de 6 horas en estado sedentario; el 21,74% informó sobre la mala calidad del sueño; una reducción de los hábitos correctos de alimentación; y un aumento de los participantes que no realizan actividad física. De acuerdo con factores socio-demográficos y antropométricos, ser estudiante (OR 2.19, CI95% 1.18 - 4, p= .012), el sobrepeso (OR 1.71, CI95% 1.19 - 2.44, p= .003), la obesidad (OR 4.45, CI95% 2.27 - 8.7, p< .001), y haber estado confinado más de 45 días se asoció con una mala alimentación. Asimismo, los bajos niveles de actividad física se asociaron con la obesidad (OR 3,2; IC95% 1,66 - 6,18, p= .001), ser mujer (OR 1,61; IC95% 1,14 -2,28, p= .006) y estar casado (OR 1,72; IC95% 1,14 - 2,61, p= .009). Además, ser estudiante se asoció con una mala calidad de sueño (OR 43,6, CI95% 5,4 - 350, p< .001). Conclusión: Este estudio sugiere que el confinamiento disminuyó los hábitos de vida saludables como la buena nutrición, la actividad física, y afectó la calidad del sueño en sujetos jóvenes.

Background and PurposeEvidence‐based practice (EBP) has been widely implemented in different areas of biomedical sciences. However, no precedents in Argentina have investigated the data regarding the knowledge and difficulties related to EBP in physiotherapists. The purpose was to describe the self‐reported behavior, knowledge, skills, opinion, and barriers related to the EBP of Argentinian physiotherapists.MethodsA customized descriptive survey was conducted among 289 physical therapists in Argentina. The data were analyzed descriptively.ResultsThe response rate was 56% (163/289). Argentinian physiotherapists update themselves through scientific articles, meetings, congresses, and courses. They reported having sufficient knowledge to use EBP, informing patients about treatment options, and considering their choices in the decision‐making process. However, there were inconsistencies in responses regarding experience with EBP during undergraduate or postgraduate studies. The most frequently reported barriers were lack of time, difficulty in understanding statistics, and difficulties with the English language of scientific articles.DiscussionEBP in Argentine physiotherapists is still poorly understood. Time, language, and difficulties in understanding statistics are the most important barriers to the implementation of EBP. Undergraduate and postgraduate courses are warranted to improve the clinical decision‐making process.

Background: There is a gap in the research about the influence of wearing or not wearing a prosthesis for muscle strength assessment in transfemoral amputees (TFA) and how it is associated with functional mobility. Objective(s): The aim of this study was to compare the muscle isometric strength of the residual limb with and without the prosthesis in people with TFA and to analyze associations between muscle strength and functional mobility. Study Design: Cross-sectional study. Methods: 20 subjects with TFA were included. A handheld dynamometer was used for the assessment of residual limb muscle strength. Functional mobility was assessed with the Timed Up and Go test. The Wilcoxon rank sum test with the rank biserial correlation effect size were used. Results: There were statistically significant differences when testing isometric strength of the residual limb with and without the prosthesis (flexion [p = 0.007], extension [p < 0.001], and abduction [p = 0.003]). There was association between functional mobility and flexion and abduction strength with the prosthesis (p = 0.005, p = 0.01). Conclusions: Measurements of muscle strength of the residual limb were different when assessed with and without the prosthesis. Isometric strength of the residual limb in abduction and flexion using the prosthesis were correlated with functional mobility.

Background: Chronic nonspecific low back pain (CNSLBP) is the leading cause of long-term pain and disability. There is evidence suggesting a relationship between CNSLBP in adult women and altered hip kinematics and gluteus medius (GM) muscle function. However, this association has been less studied in young women. Objective: To assess the association between lower limb and pelvis kinematics in the frontal plane, and GM strength and electromyographic activity in young women with CNSLBP compared with an age-matched control group of asymptomatic women. Methods: In this cross-sectional study, 32 young women with CNSLBP ([Formula: see text] months of pain; Oswestry index range: 21–40%) and 20 healthy age-matched women were included. The frontal plane projection angle (FPPA) and contralateral pelvis drop (CPD) at the endpoint of the single-leg squat (SLS) test were measured through photogrammetry. Mean GM muscle activity during the SLS and peak isometric GM strength was measured using surface electromyography (sEMG) and hand-held dynamometry, respectively. Results: The Hotelling’s trace showed no significant differences between groups when the variables were considered as a composite ([Formula: see text]; [Formula: see text]). Also, the univariate results showed no individual differences between groups considering each variable separately. Conclusions: The results showed no association between CNSLBP, hip and pelvis kinematics, and GM strength and activity in young women.
