Effect of Whole Body Vibration With Weighted Vest on Motor Function in Children With Spastic Diplegia

Study Overview
=================
Brief Summary
-----------------
Whole body vibration has been widely used in rehabilitation of individuals with disabilities as well as children with cerebral palsy. Previous studies have demonstrated the efficacy of Whole body vibration on balance, gross motor function, spasticity and bone density in children with cerebral palsy. However, adding extra weight during Whole body vibration for children with cerebral palsy as a means of enhancing the potential effects of Whole body vibration is unknown. Therefore, the aim of this study is to examine the effect of Whole body vibration with weighted vest on trunk control, balance and gross motor function in children with spastic diplegia.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Group I<br>15 Children with spastic diplegia in this group will a designed physical therapy program for 60 minutes per session in addition to WBV for 10 minutes, three times a week, for three consecutive months. | Other: physical therapy program<br>* Flexibility exercises to restore joint mobility of soft tissues, Static and dynamic balance exercises, Functional gait training , Functional strengthening exercises will be conducted three times a week, for three consecutive months.<br>Other: whole body vibration (without extra weight vest)<br>* 9 minutes of three sets of 3-min semi-squats on the vibration platform. three times a week, for three consecutive months.<br>|
| Experimental: Experimental group<br>15 Children with spastic diplegia in this group will receive the same designed physical therapy program while WBV will be conducted while wearing a weighted vest. | Other: physical therapy program<br>* Flexibility exercises to restore joint mobility of soft tissues, Static and dynamic balance exercises, Functional gait training , Functional strengthening exercises will be conducted three times a week, for three consecutive months.<br>Other: whole body vibration (with weight vest)<br>* The extra-weight applied in the vest will be calculated as 10% of the child body weight. The vest is designed to allow small bags of sand with different weights that are distributed equally on anterior-posterior and mediolateral plans.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Trunk control | The Trunk Control Measurement Scale is used to assess trunk control and consists of static and dynamic sitting balance in children aged 8 to 15 years with spastic CP | three months | 
| Gross motor function | The Gross motor function measure-88 will be used to assess motor function in 88 items across five dimensions: (a) lying and rolling, (b) sitting, (c) crawling and kneeling, (d) standing, and (e) walking, running and jumping. dimensions D and E will be assessed in the current study The assessment of each item will be conducted carefully and scored according to the scale scoring key (scale from 0-3) with total score 100 and higher score represent better performance | three months | 
| balance | Human computer balance system will be used to assess balance to assess center op pressure and limits of stability | three months |
