The influence on gait variables of the difference in muscle strength on hamstring muscles of hemiplegic patients.

ABSTRACT

The purpose of this study is to estimate how much the motility of affected and unaffected lower limb respectively would affect the gait by comparing the difference between their affected and unaffected muscle strength and studying the correlation between such difference and their gait. The IP values gained from a quantitative electromyogram(QEMG) test were analyzed by ink-foot print method as well as the corresponding statistics were processed by T-test through SPSS. The differences in muscular strength of hamstring in unaffected limbs of hemiplegic patients only affect stride length(p <.05). The effect of difference in muscular strength of the hamstring in affected limb of hemiplegic patients on their ambulation was very different between strong and weak group in terms of walking velocity, step per minute, stride and step length, showing statistically significant difference(p <.05). In conclusion, strength exercise of hamstring muscles is effective on improvement of gait in hemiplegic patients.
