The purpose of this study was to assess the improvement of toe tactile sensation in relation to postural stability in hemiplegic and normal elderly subjects. The subjects of this study were divided into two groups, the hemiplegic group (mean 65.8 ( 5.3 years, 6 right hemiplegic patients) and a healthy elderly group (mean 71.4 ( 2.8 years; 4 men and 4 women). The instrument for measuring standing balance was a force plate. Data were analyzed to provide a variable in the body swats index (SI:cm). The subjects were asked to stand in a relaxed posture for 2Osec. The second experiment utilized a new system which was developed for measuring tactile sensation. Moreover, three hemiplegic subjects were given the initial test and were then retested for measuring the process of recovering the absolute threshold of tactile sensation and SI. There were significant differences between the affected and unaffected great toes in the hemiparetic group. Significant difference was also found between the hemiparetic and normal elderly groups in the affected side (right side). Although there were no significant differences between the absolute threshold of tactile sensation and SI at the time of both initial test and retest of the affected side in the hemiplegic group, the result showed that the retests value was less than that of the initial test in all three subjects. These results suggest that evaluation and reeducation of sensation in the toes as an adjunct to conventional physical therapy would be more effective in reestablishing normal postural sway characteristics in hemiplegic patients than in conventional physical therapy alone.
