Abstract: ［Abstract］ Objective〖HTSS〗〓To investigate the walking ability and the recovery of common peroneal nerve after hydrotherapy in patients with common peroneal nerve injury.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Twenty patients with common peroneal nerve injury were randomly divided into 10 cases in control group and 10 cases in experimental group . The control group only performed routine rehabilitation training; the experimental group added water exercise training in addition to the routine training. The total training duration of the two groups was 40 min(40 min field training for the control group and 20 min field training, 20 min water training for the experimental group), with 5 times a week for 8 weeks. After training, the two groups of calf circumference, dorsiflexion active joint mobility, 10 m walking speed, and nerve fiber conduction velocity and amplitude were compared.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓There was no significant difference in the calf circumference between two groups after treatment comparing before the training(P＞005). There was no difference in the calf circumference between two groups after treatment. After treatment, the active anterior flexion of the dorsiflexion and the walking speed of 10 m were better than those before treatment. The difference was statistically significant(P＜005), but the increase was greater in the experimental group. The active joint mobility and 10meter walking speed of the dorsiflexion were more than that of the control group after treatment(P＜005). After treatment, the motor nerve conduction velocity and amplitude were higher in the experimental group than before treatment(P＜005). After the treatment, the total nerve motor nerve conduction velocity was higher than that before treatment, and the amplitude was not significantly different from that before treatment(P＞0.05). After treatment, the conduction velocity and amplitude of the experimental group were higher than the control group, and the difference was statistically significant(P＜005). After treatment, the sensory nerve conduction velocity and amplitude of the experimental group were higher than before treatment(P＜005). The conduction rate of the control group was higher than that before treatment. The experimental group was higher than the control group after treatment, and the amplitude of the control group after treatment was compared with that before treatment. The difference was not statistically significant(P＞005). There was no significant difference between the experimental group and the control group after treatment(P＞005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Eight weeks training in water can effectively improve patients nerve recovery, and helping patients improve their walking ability.
