BACKGROUND: Cerebral palsy is the commonest cause of physical disability in children, with no cure till now. Extensive sensory input to the motor cortices and to the motor descending pathways raises the potential of using sensory stimulation of the extremities to produce neuroplasticity to improve motor function in cerebral palsy patients. OBJECTIVES: To investigate the effect and usefulness of local palmar vibration therapy in improving motor hand function of cerebral palsy children. METHODS: A single blinded, randomized controlled trial (Registry number CTRI/2013/05/003700) was designed to investigate the effect of local vibration therapy, a sensory input, on the change in motor hand function in cerebral palsy children. Thirty eight cerebral palsy children were screened and 23 were recruited as per the inclusion and exclusion criteria, randomised and allocated to treatment and control groups. Twenty children completed the study. The control group received standard conventional therapy. The intervention group, in addition, received bilateral localized 50 Hz palmar vibration therapy daily for 5 min, 5 days per week, for 4 weeks. RESULTS AND DISCUSSION: Interim analysis revealed no statistically significant difference in the change in hand function or activities of daily living between the groups. However, intra-group analysis revealed significant improvement of hand dexterity of both dominant and non-dominant hands in the intervention group but only of the dominant hand in the control group, which is suggestive of a beneficial effect of vibration therapy in the intervention group. Further, the bilateral improvement in hand function in the intervention group, reveals that the protocol used in the study for the application of vibration therapy, has no effects of inter-hemispheric cortical inhibition on the non-dominant cortex. The findings of the interim analysis defend the appropriateness of studying the role of sensory stimulation as a mode of therapy, to enhance hand dexterity in Cerebral palsy children.
