Whole Body Vibration Versus Functional Strength Training On Balance In Children With Hemiparetic Cerebral Palsy

Study Overview
=================
Brief Summary
-----------------
The study will be directed to compare which of whole body vibration (WBV) training and Functional strength training (FST) has better effect on balance in children with hemiparesis

Detailed Description
-----------------
Hemiparesis is a type of hemiplegia where mild muscle weakness causes balance disturbances because one side of the body is affected such as the arm, chest leg or face. Muscle weakness is commonly associated with abnormal bone development, leading to increased susceptibility to fractures, most cerebral palsy children have deficits in balance, coordination, and gait throughout childhood and adulthood. So, it is essential to seek an ideal physical therapy program to help in solving such widespread problem. Balance control is important for competence in the performance of most functional skills, helping children to recover from unexpected balance disturbances, either due to slips and trips or to self- induced instability when making a movement that brings them toward the edge of their limit of stability Whole body vibration is mechanical oscillation, defined by amplitude and frequency, generates a force that acts on whole body. It is a training method for muscle tone modulation that is increasingly used in a variety of clinical situations. Functional strength training (FST) is an effective method of exercise therapy. It can be combined with traditional physical therapy methods and can be successfully combined with most rehabilitation and exercise equipment. It provides postural stability while promoting independence with confidence. The current study will be directed to compare which of whole body vibration (WBV) training and Functional strength training (FST) has better effect on balance in children with hemiparesis.
