Validez concurrente y confiabilidad inter e intra evaluador de la flexicurva para la medición de la cifosis torácica en adultos mayores
Concurrent validity and inter and intra evaluator reliability of the flexicurve for the measurement of thoracic kyphhosis in older adults
Resumen
Objetivo: determinar la validez concurrente y confiabilidad inter e intra evaluador de la flexicurva para la medición de la cifosis torácica en adultos mayores. Considerando la importancia de métodos de evaluación precisos y no invasivos para esta población, el estudio se centró en establecer la eficacia de la flexicurva comparándola con mediciones más convencionales. Método: se seleccionó una muestra de 26 adultos mayores, con una distribución equitativa por género y una edad promedio de 72.6 años. Se utilizó la flexicurva y el inclinómetro para medir la cifosis torácica, y se calculó la sensibilidad, especificidad y confiabilidad intra e inter observador de la flexicurva. Además, se realizaron comparaciones estadísticas para evaluar las diferencias entre las mediciones de ambos instrumentos. Resultados: la flexicurva mostró una sensibilidad del 100% y una especificidad del 73.7% en la detección de hipercifosis. La confiabilidad intraobservador fue de 0.728 y la interobservador de 0.716, indicando una confiabilidad moderada a buena. Se encontraron diferencias significativas entre las mediciones de la flexicurva y el inclinómetro. Conclusiones: La flexicurva se demostró como una herramienta confiable y válida para la evaluación de la cifosis torácica en adultos mayores. Los hallazgos sugieren la necesidad de estudios adicionales para explorar la aplicación de la flexicurva en distintas poblaciones y mejorar la precisión de las mediciones.
Objective: determine the concurrent validity and inter- and intrarater reliability of the flexicurve for measuring thoracic kyphosis in older adults. Considering the importance of accurate and non-invasive assessment methods for this population, the study focused on establishing the effectiveness of the flexicurve by comparing it to more conventional measurements. Method: a sample of 26 older adults was selected, with an equal distribution by gender and an average age of 72.6 years. The flexicurve and inclinometer were used to measure thoracic kyphosis, and the sensitivity, specificity, and intra- and interobserver reliability of the flexicurve were calculated. In addition, statistical comparisons were made to evaluate the differences between the measurements of both instruments. Results: the flexicurve showed a sensitivity of 100% and a specificity of 73.7% in the detection of hyperkyphosis. The intraobserver reliability was 0.728 and the interobserver reliability was 0.716, indicating moderate to good reliability. Significant differences were found between the flexicurve and inclinometer measurements. Conclusions: The flexicurve was demonstrated as a reliable and valid tool for the evaluation of thoracic kyphosis in older adults. The findings suggest the need for additional studies to explore the application of the flexicurve in different populations and improve measurement accuracy.
