Report Errors
Objective: The purpose of this study is to quantify the hand functionality using the tracking task and investigate the difference between elderly and young group. Method: A total of 8 healthy adults (4 elderly and 4 young females) participated in this study to evaluate the effect of age, hand and target force level on the tracking performance. Participants were asked to exert a grip force attempting to minimize the difference between the target force and their exerting force. Results: The elderly group showed 28.4% larger tracking error than that of young group. This means that the age-related change declined the ability to control the grip force. It was noted that the difference of tracking error between age groups was more remarkable at the low target force levels (5, 15% MVCs). This means that elderly women had a lower ability to maintain precise forces than young group. Conclusion: Hand functionality could be quantified by using the tracking task. Effect of aging on hand functionality was found in this study through the tracking task. Application: The results of this study are conjectured to be applicable to physical treatment or rehabilitation.
