The final rehabilitation evaluation program consisted of 25 stroke subjects and 25 comparison patients. There were no significant differences in demographic data and three types of dependent variables in pretest period between two groups. Ill balance evaluation (Figure 3), experimental group presented better improvement of balance than control group in posttest and one-month after outpatient (t=2.32, P<0.05; t=3.14, P<0.01). In functional independence evaluation (Figure 4), there were no significant differences in posttest period between two groups (t=1.58, P>0.05), experimental group presented better improvement than control group in one-month after outpatient (t=2.13, P<0.05). In psychological responses evaluation (Figure 5), experimental group presented better improvement of psychological negative responses than control group in posttest and one-month after outpatient (t=2.14, P<0.05; t=-2.25, P<0.05).
This study suggested that EMG recognition system built in upright stepping device could enhance the improvement of balance, functional independence, and psychological negative responses for stroke patients. Further research can be verified that of a useful medical instrument in a long-term rehabilitation period (three-month, six-month, and one-year) and other kinds of patients.
