Abstract
Antecedentes: El Action Research Arm Test (ARAT) es un instrumento validado
para la medición de funcionalidad de las actividades de la extremidad superior
(ES) patologías neurológicas, evaluando la manipulación, alcance y agarre,
orientadas a movimientos funcionales. La acelerometría es una medición
instrumentada del movimiento, útil para monitorear objetivamente actividades de
la ES. En este sentido, la posibilidad de mediciones funcionales instrumentadas
cobra relevancia ante la posibilidad de obtener variables del control del
movimiento difíciles de objetivar. Así, dispositivos de alta accesibilidad y bajo
costo pueden ser claves para su aplicación en la clínica, por lo que su validación
en parámetros entregados es fundamental.
Objetivo: Comparar la similitud entre sensores de aceleración en la captación del
movimiento en dos subpruebas del Action Research Arm Test en sujetos sanos.
Hipótesis: La medición de MetaMotionR y Sensor Kinetics Pro presentan
similitudes en los patrones acelerométricos ante la aplicación de dos subpruebas
del Action Research Arm Test.
Metodología: Se registraron 30 sujetos jóvenes de la Universidad Finis Terrae.
Se aplicaron dos subpruebas del ARAT (P1) y (P2) con ambos acelerómetros de
forma simultánea.
Resultados: De acuerdo al análisis realizado, tanto para P1 y P2, se obtuvieron
similitudes en sus patrones acelerométricos, según la medición de sus peak,
demostrando que no hay diferencias significativas entre acelerómetros.
Background: The Action Research Arm Test (ARAT) is a validated instrument for the measurement of functionality of the activities of the upper limb (ES) neurological pathologies, evaluating manipulation, reach and grip, oriented to functional movements. Accelerometry is an instrumented measurement of movement, useful for objectively monitoring SE activities. In this sense, the possibility of instrumented functional measurements becomes relevant given the possibility of obtaining variables of the control of movement that are difficult to objectify. Thus, devices with high accessibility and low cost can be key for their application in the clinic, so their validation in delivered parameters is essential. Objective: To compare the similarity between acceleration sensors in capturing movement in 2 subtests of the Action Research Arm Test in healthy subjects. Hypothesis: The measurement of MetaMotionR and Sensor Kinetics Pro show similarities in the accelerometric patterns after the application of two subtests of the Action Research Arm Test. Methodology: 30 young subjects from Universidad Finis Terrae were registered. Two ARAT subtests (P1) and (P2) were applied with both accelerometers simultaneously. Results: According to the analysis carried out, both for P1 and P2, similarities were obtained in their accelerometric patterns, according to the measurement of their peaks, showing that there are no significant differences between accelerometers.
