简要总结
study aims to evaluate the efficacy of high and low frequency TENS on spasticity, strength and functional status in stroke patients. It may provide further knowledge concerning the use of TENS for motor impairments in stroke patients and may clarify ambiguities to some extent.
详细描述
Despite the positive effects of electrical stimulation proved on motor impairments of affected limb, the evidence is still not conclusive. There still remains a question mark regarding the effectiveness and optimal stimulation parameters of TENS. there has been conflict regarding the TENS parameters (frequency, duration, intensity) among different studies. To date TENS parameters used in different studies to reduce spasticity range from frequency of 1.7-100 Hz, duration from 15-60 minutes and sessions from 1-30. The use of different parameters may account for the contradictory results related to effectiveness of TENS.

结局指标
主要结局
Modified Ashworth Scale (MAS)
时间窗: 8 weeks
Modified Ashworth Scale (MAS) is a subjective method used clinically to measure spasticity. It has verified validity to test spasticity. MAS is six point scale (0,1,2,3,4,5) with a 0 indicating no resistance and 5 indicating rigidity. It has good intra and inter-rater reliability with inter-rater reliability of r= 0.92 and intra-rater reliability at r=0.86.

- Manual Muscle Testing (MMT)(8 weeks)
- Action Research Arm Test (ARAT)(8 weeks)
