Abstract: Objective To investigate the effects of conventional rehabilitation therapy with the sinusoidal modulated medium frequency electrotherapy in the treatment of balance and motor function of the patients with stroke hemiplegia. Methods 96 patients met the inclusion criteria with hemiplegia were randomly divided into treatment group and control group with 48 cases in each group, the patients of the two groups received conventional rehabilitation therapy, the treatment group increased sinusoidal modulated medium frequency electrotherapy treatment, before and after treatment the balance function of the patients in the 2 groups were measured with Berg balance scale (BBS), modiifed Barthel index (MBI), the motor function assessment (FMA) was evaluated with Fugl-Meyer’s. Results After treatment, BBS, MBI, FMA scores were signiifcantly improved in the patients of the two groups (P<0.01), considering the score comparison, the results of the treatment group were higher than that of the control group (P<0.05). Conclusion Routine rehabilitation combined with sinusoidal modulated medium frequency electrotherapy is superior to conventional rehabilitation therapy in improving balance and motor function in hemiplegic patients.
