Estudio cinemático de la mano para movimiento de oposición del dedo pulgar y movimientos de flexión y extensión de los dedos índice, medio, anular y meñique

Abstract

The current research studies the kinematic movements of the hand for the opposition movements of the thumb and flexion-extension movements of the fingers by photogrammetry (motion capture). To perform the aim, the toolbox “BTS Smart” was used. This software helps to realize the motion capture, the data treatment and to get the kinematic movements. Protocols for each exercise executed were defined and carried out in the “BioFoot” Lab. The data were collected through optoelectronic cameras capture movements of reflective markers placed in the hand as the International Society of Biomechanics (ISB) suggest it, in nine patients who didn’t have any neuronal, rheumatologic or traumatological problems. The mean, the standard deviation, the range of movement of the adduction-abduction movements of the thumb and the flexion-extension movements of the fingers were obtained by data acquired via the movements study. Subsequently, the software "OpenSim" was used to verify the correct movement expected to get of the fingers thought the data previously acquired and implanted in the virtual model. Eventually, the initial points of each movements were determined, and it can possible to conclude that the movements range of each one of the joints in the hand that was obtained in the present research are acceptable.
