Modeling of Wrist and Hand Motion while Performing Functional Task

Abstract

A large prescriptive data set of wrist, metacarpal arch fingers and thumb movements has been collected using twenty-four 4mm hemispherical passive reflective markers placed on the wrist, hand and fingers. Movements of each participant were captured by a set of 6-camera infrared motion analysis system (QUALISYS) sampling at 60Hz while undertaking a clinical hand function assessment, the Southampton Hand Assessment Procedure (SHAP). Without Muscle Contraction and With Muscle Contraction versions of objects are assessed and were tested, characteristics of individual movement strategies presented and initial results have shown interesting variations that correspond with physiological and functional approaches to movement. With the whole designed system, patient can improved hand function with the result of vigorous physical activity through the SHAP procedures, from the supervision of researcher can determine the functionality of one patient’s hand and wrist which will benefit subjects with a dramatic effect on one’s daily life as we know exercise is related to better health. Using advanced software such as Visual 3D and Qualisys Tracking Manager, researcher can monitor patient’s recovery progress, with suitable angle of calculation of one’s fingers, acceptable force and velocity of one’s produced depending on age and size of hand of subjects.
