The purpose of this study was to examine the effects of excitability of the spinal alpha motor neurones using the stretch and, vibratory stimulation for on post-stroke patients with upper limb spasticity. The subjects of this study were 14 hemiplegic patients who had been over six months since the day of onset. The group Ⅰ(n=7) stretch stimulation was applied, and the group Ⅱ(n=7) vibratory stimulation was applied direct spastic muscle. Changes in spinal neuronal excitability, H reflex and F waves to measure were used.
Measurements were performed pre and then post, post 10 minutes, and post 20 minutes during 3 different testing sessions. and measure muscle tone MAS(Modified Ashworth Scale), MFT(Manual Function Test) test for the upper extremity function with the following results were obtained.
First, after stretch and, vibratory stimulation was applied to the hemiplegic patients, H latency had more significant increased(p<.05), H amplitude and H/M ratio had more significant decreased than before treatment(p<.05).
Second, after stretch and, vibratory stimulation was applied to the hemiplegic patients, F latency had more significant increased(p<.05), F amplitude and F/M ratio had more significant decreased than before treatment(p<.05).
Third, after stretch and, vibratory stimulation was applied to the hemiplegic patients, Evaluation of muscle tone were significantly decreased in MAS than before treatment(p <.05).
Fourth, after stretch and, vibratory stimulation was applied to the hemiplegic patients, Evaluation of upper extremity function in MFT vibratory stimulation group was significantly increased than before treatment(p <.05).
These results of this study showed that stretch and, vibration stimulation was applied directly to spastic muscle and spinal cord neuronal excitability was reduced, also reduce muscle tone and vibration stimulation was improve upper extremity function Therefore, the clinical application of stretch and, vibration stimulation in stroke rehabilitation are able to help.
