Abstract
The Posterior Leaf Spring (PLS) has been used for hemiplegic patients in order to help their walking and to increase their balance function. Past studies have mainly focused on the PLS's influence on patients' walking without taking balance function into consideration. The purpose of this study was to identify the immediate effect of PLS on the standing balance in hemiplegic patients. Fifteen hemiplegic patients participated in this study: 10 men and 5 women, with an average age of 53.8 years. Standing balance was measured using a computerized dynamic posturography device under three conditions namely bare-foot standing, standing in shoes without PLS, and standing in shoes with PLS. The results were as follows: 1) The composite equilibrium scores of patients who stood in shoes only and stood in shoes with PLS were higher than those of patients who stood bare-foot. 2) There were no statistical difference in the composite equilibrium scores between the standing condition of patients who stood bare foot and that of patients who stood in shoes with PLS. In conclusion, it is not clear whether or not the PLS affects the standing balance of hemiplegic patients. Further study is required to determine the precise effect of the PLS on standing balance in hemiplegic patients who are not wearing shoes. This is particularly relevant in Korea culture where custom demands the removal of shoes when entering any house or even many restaurants.
