Abstract

We evaluated the characteristics of lower limb muscle activity by measurement of the lower limb loading force in elderly hemiplegics with gait disturbance. The subjects consisted of 12 elderly stroke patients with hemiplegia (mean age, 74.0±5.0 years) requiring assistance for walking. For the limb on the non-affected side, stress associated with the stepping-on action was measured, and the muscle discharge was compared among lower limb muscles (rectus femoris, long head of the biceps femoris) and those of the crus (tibialis anterior, gastrocnemius). Comparison of the muscle discharge among the 4 muscles showed significant difference (F value=6.31, p<0.01). As a result of the multiple comparison test, the muscle discharge was significantly greater for the quadriceps femoris and tibialis anterior than for the biceps femoris and gastrocnemius (p<0.01). Concerning the characteristics of muscle activity in the measurement of the lower limb loading force in elderly hemiplegics with gait disturbance, the results of this study suggest that the activity of posterior lower limb muscles is lower, the and simultaneous contraction observed in healthy adults does not occur.
