A study on the standardization of healthy subject data for upper limb rehabilitation of stroke patients using a haptic system

Abstract

A previous study on the rehabilitation of stroke patients using the haptic system was conducted. However, the past study lacked objective methods for comparing and evaluating patients’ conditions. In order to remedy this short coming, the present research focused on the standardization of healthy subject data in order to compare and evaluate patients’ conditions. Experiments were performed by selecting healthy males and females within the ages of 20 and 60 according to certain standards. Since the circle program among haptic system programs was made by considering the most basic motions among daily life motions, this research was performed by using the circle program. The experimental data on the trajectory errors of the circle motions and the amount of muscular motion were standardized by classifying them into age groups, gender, changes of the viscosity (No viscosity, +viscosity, −viscosity), eight types of the motion (FEL, FFL, FFM, FEM, RFL, REL, REM, and RFM), and two types of muscle (Biceps Brachii: BB, Triceps Brachii: TB).
