Feasibility of Whole Body Vibration Therapy in Individuals with Dystonic or Spastic Dystonic Cerebral Palsy: A Pilot Study.

Objective: To examine the feasibility and practicality of whole body vibration therapy for individuals with dystonic or spastic dystonic cerebral palsy.

Design: Pilot study.

Subjects: Children and adults with dystonic or spastic dystonic cerebral palsy.

Methods: Study participants received total body vibration therapy when standing still on a vibration platform for 3 bouts, duration 3-min, of vibration (20 Hz, 2 mm amplitude), 4 days per week for 4 weeks in addition to their usual therapy. All participants were assessed at baseline and completion of the study using the Gross Motor Function Measure Item Set, Timed Up and Go test, Barry-Albright Dystonia Scale, Edinburgh Visual Gait Score, and Pediatric Evaluation of Disability Inventory.

Results: Ten participants (mean age 18.60 years (standard deviation (SD) 14.68); 9 males, Gross Motor Function Classification System level II-IV) completed the study with more than 90% attendance rate. All participants tolerated the protocol with no adverse events.

Conclusion: The vibration treatment protocol was feasible and safe for all participants. With no significant differences found in all the outcome measures, future studies with more rigorous study designs are required before this intervention is recommended for this population group.
