Abstract :
This experiment was designed to develop a system to evaluate patients´ performance for balance control in the upright position and to feedback this information to the patients to improve the therapeutic effect. Results showed that the number of zero crossings showed no significant differences when the subject stands with both legs. While standing with one leg, movement in right/left direction appeared more than that in front/rear direction. Ratio of the area appeared higher for standing with both legs than with one leg. The results show no significant differences between the ratios standing with one leg
