However, many of them lack associative value with the actual functional status of the older adults, medical history, and comorbidities. Methods: Analytical study with cross-sectional design. Three functional tests were performed (Timed Up & Go, Five Times Sit to Stand Test, and Unipodal Station Test) in 148 independent older adults (mean = 74.8 SD = 7.2), 83 non-fallers, and 58 with self-reported accidental falls in the last year. Other factors, such as grip strength and abdominal circumference, were considered. Results and Discussion: The functional tests presented associative value in older adults with a history of falls (p < 0.05). The grip strength has a statistically significant correlation between both groups. Functional tests can discriminate the risk of falls in independent older adults and those with similar comorbidities. Conclusion: The three functional tests applied show associative values in falling older adults. The grip strength presented associative value with the functional tests.

Aim: To evaluate the sensitivity and specificity of TUG as a predictor of falls in older adults. Material and methods: TUG was measured in 148 independent community-dwelling older adults aged 75 ± 7 years (85% women). Of these, 58 reported having a fall in the previous year. Analysis of the ROC (Receiver Operating Characteristic) curve was performed to assess the sensitivity and specificity of common cutoff times used in clinical practice. The times required to perform the TUG as quickly as possible (best fitted time) and at the usual pace (common time) were registered. Results: Participants with a history of falls had higher TUG times than their counterparts who did not fall (10.9 ± 3.9 and 9.2 ± 2.6 s, respectively). By age groups, only in the 60-69 age group the differences between those who fell and those who did not, were statistically significant (p < 0.05). A cutoff of 9s generates the better sensitivity and specificity for the test (0.60 and 0.57, respectively). For 60-69 age group the best cutoff time is 8.2s, with an increase in sensitivity and specificity to 0.73 and 0.68, respectively. Conclusions: There were differences in TUG values between participants with and without a history of falls. Determining TUG cutoff values by age groups improves the sensitivity and specificity of the test, especially in the 60-69 age range.

Las metodologías docentes conforman una piedra angular en este aspecto, las cuales pueden marcar positiva o negativamente al estudiante. Objetivos: Evaluar la experiencia de aprendizaje durante la práctica profesional, en estudiantes de Kinesiología. Material y Método: Se aplicó una encuesta a estudiantes de la carrera de Kinesiología que cursen su práctica profesional, pertenecientes a la Universidad Católica Silva Henríquez, la cual evalúa cinco aspectos de la docencia clínica: organización de los programas, práctica docente, rol del estudiante, ambiente de aprendizaje y experiencia clínica. Resultados: La dimensión mejor evaluada fue rol del estudiante. Las más críticas en términos académicos fueron organización de los programas y práctica docente. El conocimiento de estrategias metodológicas, de evaluación por parte del docente, y el recurso humano para el aprendizaje fueron los puntos más críticos. Conclusiones: La formación del docente clínico en materias pedagógicas es trascendental para el buen desempeño de éste. La utilización de todos los recursos que abarque una adecuada formación pedagógica en docencia clínica se perfila como un eje fundamental para el aprendizaje significativo del estudiante, en este campo de su formación profesional.

The existing diagnostic methods for this disorder are found in the English language only, which leads to difficulties in finding valid and agreed diagnostic methods by speech therapists to apply to the Spanish-speaking population. Hence, this study aims to provide the translation of an evaluation tool which is suitable for Spanishspeaking countries and that facilitates phonoaudiological work in the diagnosis. The method that will be used is that of translation-retranslation, to which the analysis of an expert opinion will be incorporated to give validity to the instrument. The results expose a wide acceptance of the instrument (94% of positive results) with substantial agreement among experts (IRR inter rater reliability), presented as agreement probability for the entire instrument of 0.57 (57%). In conclusion, this study provides a ...
