The effect of 40 HZ sound wave vibration on spasticity and motor function in children with cerebral palsy

Introduction: As the motor system relies heavily on deep sensory stimulation, recent studies have investigated the effect of vibration stimuli. Although research suggests a positive influence of vibration on motor performance in individuals with neurological disorders, there are very limited numbers of studies in children with cerebral palsy (CP). The primary objective of the present study was to evaluate the effects of sound wave vibration therapy on spasticity and motor function in children with CP. The second objective was to investigate the nature and strentgh of relationship between change in spasticity level and motor outcome. Materials and methods: In this 3-month trial, 89 children with spastic CP were randomized to either continue their physiotherapy treatment (PT) or to receive vibration therapy twice a week in addition to their PT program. The randomization was stratified according to Gross Motor Function Classification System (GMFCS) level to ensure similar functional ability in both study groups. The outcomes measures were spasticity level in upper and lower limb as assessed by Modified Modified Ashworth Scale (MMAS) and gross motor function as assessed by global changes in Gross Motor Function Measurement (GMFM). Results: Significant group differences were detected for changes in spasticity level and gross motor function after the three months intervention. There was a clear and statistically significant association between changes in spasticity and motor outcome. Conclusion: Vibration therapy may decrease spasticity and improve motor performance in children with CP. The obtained results serve as valuable input for evidence-based treatments in paediatric neurorehabilitation.
