About this trial
Whole-body vibration (WBV) and treadmill training (TT) are commonly-utilized rehabilitation interventions for children with neuromotor disorders. WBV has been shown in the literature to positively affect gait and lower body spasticity in this population. However, the effects of a single session of WBV are generally transient, lasting between ten minutes and two hours. Thus, it may be necessary to combine WBV with another intervention to reinforce improved movement patterns and maximize its potential benefits. Therefore, the aim of this study is to investigate the effects of the addition of a single bout of WBV to a single bout of TT on the lower extremity spasticity and gait parameters of ambulatory children with CP.

Whole Body Vibration & Treadmill Training
Other interventionEight bouts of 90 seconds of vibration at 20 Hz and an amplitude of 2 mm on a Galileo Med-L side-to-side-alternating WBV plate (StimDesigns LLC, Carmel, CA, USA) followed by ten minutes of treadmill walking at 110% self selected overground walking speed.
