Effect of Vibration on Shoulder Proximal Stability in Children With Cerebral Palsy

Effect of Whole-body Vibration on Shoulder Proximal Stability in Children With Cerebral Palsy

Objectives: Children with cerebral palsy have weak proximal stability which not only affects range of available motion but also reflects on distal dexterity. These have a great impact on their mobility and efficiency of daily living activities. Vibration has been regarded as an effective exercise method to improve muscle strength and endurance. The aim of this study was to determine the effect of vibration on shoulder proximal stability in children with cerebral palsy.

Methods: Fifty children with cerebral palsy from 4 to 9 years old participated in this study and were selected from the outpatient clinic of faculty of physical therapy. They were divided into two groups of equal sizes randomly. The control group received a conventional physical therapy program in addition to Sling exercise therapy, and the study group received the same conventional physical therapy program in addition to Sling exercise therapy (SET) and Whole-body vibration (WBV). Shoulder muscle strength was assessed for both groups by using Lafayette manual muscle tester before and after treatment.

Inclusion Criteria:

• children with cerebral palsy affecting weight bearing of the upper limbs.
• Aged from 4 to 9 years.
• Both gender participated.
• Having grade 1 and 1+ spasticity according to the Modified Ashworth Scale.

Exclusion Criteria:

• Congenital anomalies.
• Surgical or neurological disease of the upper limbs.
• Osteopenia or osteoporosis.
