NCT03916770

Brief 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. 1.WBV ; reduces plantar flexor spasticity after stroke
  2. 2.WBV decreases poststroke spasticity, by decreasing increased stretch reflex and motor neuron activity.

Outcome Measures

Primary Outcomes (4)

  • spasticity-torque

    Spasticity will be measured as a torque. The unit is Nm

    4 weeks

  • 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

  • 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

  • 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

Study Arms (2)

whole body vibration

ACTIVE COMPARATOR

WBV(whole body vibration) will be applied to interventional group for 4 weeks, 3 days a week, a total of 12 sessions while standing upright with the WBV powerplate pro5 device.(Vibration frequency: 30Hz, amplitude: 2.2 mm at progressively increasing duration)

Device: Real vibrator

Sham whole body vibration

SHAM COMPARATOR

The sham WBV will be applied to the Control group. A WBV device with 99.5% weakened amplitude will be used for sham WBV. (Application duration of the sham WBV will be same as WBV in the treatment group ).

Device: Sham vibrator

Interventions

The Sham control group will have WBV the same time,in the same position with the same frequency but 99.5% weakened amplitude.

Also known as: Sham WBV
Sham whole body vibration

The intervention group will have WBV(frequency:30Hz,amplitude:2,2mm,at upright position

Also known as: Real WBV
whole body vibration
