Antispastic Effect of Transcutaneous Electrical Nerve Stimulation and Acupuncture in the Stroke Patients

ABSTRACT

Spasticity is common stroke in patients, and its management has been considered as one of the major problems in stroke rehabilitation. The goal of this study was to determine if transcutaneous electrical nerve stimulation(TENS) and acupuncture would reduce the muscle spasticity. To estimate the efficacy of electrical stimulation for the treatment of spasticity TENS(100 Hz, asymmetric bipolar pulse current) was applied to the skin over the extensor muscles of spastic limbs for 20 minutes, once a day in six stroke patients. In addition, acupuncture was also applied to the acupoints of extensor muscles of all extremities and face for 20 minutes twice a day to determine the efficacy of acupuncture for the treatment of spasticity in six stroke patients. As controls subjects, six stroke patients were examined without TENS or acupuncture treatment. In experimental groups, the efficacy of treatment was measured 1, 5, 10, 15 days and 20 days after treatment with either TENS or acupuncture using the spasticity measurement methods (modified Ashworth scale, ankle clonus score, and H/M ratio). Based on the results from the present study, we have concluded that the H/M ratios of affected spastic limbs were significantly higher than those of unaffected limbs (p<0.05). TENS and acupuncture therapies lessened the spasticity of affected limbs of stroke patients when measured with the modified Ashworth scale however not with the H/M ratios nor with the ankle clonus scores.
