Abstract

Purpose: We investigated the changes that effects of load stimulation (LS) on static balance and muscle activities in normal healthy elders and chronic stroke patients. Methods: Subjects were instructed twenty normal healthy elders (8 men and 12 women) and ten chronic stroke patients (4 men and 6 women). They were tested while standing on a force platform under two conditions; LS, no LS were applied in random order. Prior to testing, adhesive surface EMG electrodes were fastened to the skin overlying the right (non-paralytic side in stroke patient) bellies of tibialis anterior (TA) and lateral gastrocnemius (LG) muscles. They were assessed on postural sway and %MVC (Maximum voluntary contraction) of TA and LG. Results: Participants showed that the application of LS brought about a decrease in postural sway as expressed by average sway path and velocity. %MVC of TA and LG were increased. The application of LS to normal and stroke patients decreases postural sway during quite stance. Conclusion: These findings the application of LS to normal and stroke patients improves static balance.
