To observe and analyze the effect of isokinetic muscle strength training on sEMG of patients after total hip arthroplasty, and to explore the effect on improving quadriceps femoris and hamstring muscle strength. The objects of this study were 160 soccer players who underwent total hip arthroplasty in our hospital. The two weeks after the operation, intermittent isokinetic strength training at multiple angles of the affected side was conducted once a day. At the same time, before the first training, 7 days and 14 days after the training, the surface electromyography signals of the affected limb and the quadriceps femoris and hamstrings of the healthy limb during the squat were measured. The electromyography integral value (iEMG value) of squat exercise was taken for analysis three times, and the changes of quadriceps femoris, hamstrings and hamstrings/quadriceps ratio (H/Q ratio) of the affected and healthy limbs were observed. Before the training, the iEMG values of patients' femoral quadriceps and hamstring of the affected limb were significantly lower than those of the healthy side, p<0.05. At 7 and 14 days after the training, the iEMG values of the quadriceps femoris and hamstrings of the affected side showed a significant increase, p<0.05. After the isokinetic muscle training, the iEMG values of the quadriceps femoris and hamstrings of the healthy side of the patient tended to decrease. For soccer players undergoing total hip arthroplasty, the isokinetic muscle strength training can promote the positive improvement of quadriceps femoris and hamstring muscle strength, and effectively enhance the stability of knee joint, which is worthy of being promoted and applied.
