Impact of Focal Muscle Vibration on Bio-psychosocial Outcomes in Cerebral Palsy

Study Overview
=================
Brief Summary
-----------------
This study aims to determine the effects of focal muscle vibration on bio-psychosocial outcomes in subjects with cerebral palsy. Mixed methods will be used and the study will be conducted in 2 phases; 1st phase is determining the effects of intervention, whereas second step is prediction of outcomes. A qualitative gait analysis will also be done.

Detailed Description
-----------------
The literature suggests the positive effects of focal muscle vibration on various motor components of cerebral palsy. Although there is a gap regarding it's effects with perspective of bio-psychosocial model, which will be the main focus of this study. The study will look for the effects of focal muscle vibration on biological, psychological and social aspects of subjects with cerebral palsy (CP). The intervention in form of focal muscle vibration and standard physical therapy will be provided for 12 weeks and the subjects will then be followed for 4 weeks to look for retention effects, and till 24 weeks for prediction of outcomes.
