PBBT and WBV Effect on Balance and Gait in Stroke

Comparative Effects of Perturbation Based Balance Training and Whole Body Vibration on Balance and Gait in Sub-acute Stroke Patients.

The goal of this clinical trial is to compare the effects of perturbation based balance exercises with whole body vibration training in sub-acute stroke patients and to evaluate their effects on balance, and gait. The main aim to :

• To evaluate their effects on balance, and gait.
• Comparison of these rehabilitation protocols and identify the more efficacious treatment.

Participants will perform perturbation based balance training and whole body vibration therapy to improve balance and gait.

If there is a comparison group: Researchers will compare both groups to see both interventions effects.

Stroke usually causes impairments in a variety of areas, such as cognition, emotion, mobility limitation, sensory loss, and there after results in imbalance and gait disability as well as impairment of the activities of daily living (ADLs). Poor balance control have a negative influence on the recovery of gait and motor function. Many therapeutic interventions, such as visual feedback training, robotic devices, mirror therapy, and motor imagery training have been performed to improve balance control.

Reactive balance training (RBT) has emerged as a potential strategy for improving balance and participants withstood greater-magnitude perturbations before requiring multiple steps, relative to those who completed weight-shifting/gait training in sub-acute and chronic stroke patients.

Whole-body vibration (WBV) therapy used in clinical practice for improving neuro-motor performance in various patient populations and this training reduce disability by improving balance, gait performance, and mobility in stroke patients.

According to previous literature there was a lack of comparison of these two studies. In previous literature, both of these therapeutic options i.e., Perturbation based balance training (PBBT) and whole body vibration (WBV) training were used separately to see the effects in stroke population but not in combination. In this study the comparison will be done between these two exercise protocols. Consequences will be manipulated for balance, and gait by using validated tools.
