Clinical Trial Summary

The primary purpose of this study is to show whether WBV application has antispastic effect. The secondary aim is to demonstrate whether WBV has neuromodulatory activity on increased stretch reflex and motor neuron activity, which is the basis of the pathophysiology of spasticity.Hypotheses of this study:Whole body vibration in poststroke hemiplegia reduces ankle plantar flexion spasticity. 1. WBV ; reduces plantar flexor spasticity after stroke 2. WBV decreases poststroke spasticity, by decreasing increased stretch reflex and motor neuron activity.

Description:

Patients with a stroke of at least 1 month before and with a history of ankle plantar flexion spasticity will be included in the study. Conventional rehabilitation program will be applied to all patients (n=48).The intervention group (n=24) will be applied for 4 weeks, 3days a week, a total of 12 sessions with the WBV powerplate pro5 device. In the WBV group, the frequency and acceleration of vibration will be 30Hz and 18.0m/s2, respectively. The WBV exercise intensity will progressively increase throughout the twelve-session. In the control group, the same procedures will be followed. However, unlike the WBV group, a vibration will be given whose acceleration is attenuated by 99.5%.The surface Electromyography (EMG) and degree of spasticity of soleus muscle will be evaluated at the beginning and end of the all sessions. Soleus H-reflex will be recorded with surface EMG.To obtain the H-reflex response, the posterior tibial nerve in the popliteal region will be stimulated by using a stimulator (FE155 Stimulator HC ADInstrument, Oxford UK) with 1 ms-pulse current. The records will be taken with the Ag / AgCl electrodes (Kendall ®Coviden, self-adhesive electrodes) placed on skin according to the SENIAM protocol. The degree of spasticity will be measured as a soleus muscle tone torque on a fixed angular velocity moving platform.The data will be recorded with the PowerLab data acquisition device

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	spasticity-torque	Spasticity will be measured as a torque. The unit is Nm	4 weeks
Primary	spasiticity-modified Ashworth scale	The spasticity degree of the plantar flexors will be evaluated by using a subjective assessment method (modified Ashworth scale-MAS)	4 weeks
Primary	spasticity-homosynaptic post-activation depression (HPAD)	Homosynaptic post-activation depression is a presynaptic mechanism regulating the excitability of the stretch reflex. Decreased presynaptic inhibition and homosynaptic depression are also thought to play a role in the pathophysiology of spasticity. The higher HPAD, the lower spasticity	4 weeks
Primary	Motor neuron activity-Hmax / Mmax ratio	Hmax / Mmax ratio defines motor neuron activity. The higher this ratio, the higher the activity of motor neuron pool	4 weeks
