Abstract:
Objective: To observe the therapeutic effect of An-pressing and Rou-kneading manipulations for exercise fatigue of the anterior tibial muscle. Methods: Sixty healthy subjects were randomly divided into two groups, 30 in each group. Isokinetic test training was employed to induce left anterior tibial muscle fatigue. After this, subjects in the observation group received 5 min of tuina treatment, while subjects in the control group just lay down for 5 min. Then the integral myoelectricity, maximum amplitude, mean frequency and slope of the anterior tibial muscle and gastrocnemius muscle were measured using a surface electromyography (EMG) during the passive movements of the ankle joints in two groups. Results: Before treatment, the integral myoelectricity, maximum amplitude, mean frequency and slope of the anterior tibial muscle during exercise in two groups were consistent under isokinetic mode (P>0.05). After 5 min of tuina or rest, the myoelectric signals during exercise in two groups were both decreased. However, subjects in the observation group obtained a remarkably increased gain and gain rates of myoelectric signal than the control group (P<0.05). This indicates that the myoelectric signals were not fully recovered, but tuina has a better effect than rest on improving the myoelectric signal of the anterior tibia. Conclusion: Rest and tuina can both improve muscle fatigue. Tuina can obtain a better effect within the same time frame.
