Effect of tibialis anterior muscle resistance training on ankle and foot dorsum extension function in hypertensive cerebral hemorrhage hemiplegia patients: A randomized controlled trial

Abstract

Background: This study aimed to investigate the effect of tibialis anterior muscle resistance training on ankle and foot dorsum extension function in patients with hemiplegia caused by hypertensive cerebral hemorrhage. Methods: Fifty cases of hypertensive cerebral hemorrhage in patients with hemiplegia were selected according to the random number table method. The patients were divided into the treatment group and control group. Each group included 25 cases, and the treatment group was given routine rehabilitation treatment and passive and active foot back stretch training (300 times/d). The control group received conventional rehabilitation treatment. The conventional rehabilitation treatment included stretching, muscle strengthening and other conventional rehabilitation treatment techniques. Surface electromyography was used to evaluate the muscle strength and tension of the triceps and tibialis anterior muscles of the affected side of the patients before and after treatment. The root mean square value of the surface electromyography (RMS) of the passive triceps extension before and after treatment was used to evaluate the muscle strength and tension of the affected side. The ratio of passive traction and relaxation of the triceps before and after treatment and the ratio of active contraction and relaxation of the tibialis anterior muscle before and after treatment were recorded. Results: There was no significant difference in surface electromyography between the 2 groups before treatment (P > .05). After 2 months of treatment, the results of patients in both groups improved compared with those before treatment. The RMS of triceps in the treatment group was significantly lower than that in the control group, and the ratio of RMS of triceps in the treatment group was significantly lower than that in the control group. The RMS during active contraction and the RMS ratio between active contraction and relaxation of the tibialis anterior muscle in the treatment group were significantly higher than those in the control group (P < .05). Conclusions: Tibialis anterior muscle resistance training can effectively improve the strength of the tibialis anterior muscle in patients with hemiplegia caused by hypertensive cerebral hemorrhage, reduce tension in the triceps calf muscle, and improve ankle joint function and foot dorsum extension.
