Effects of whole body vibration versus agility training on gait parameters for individuals with parkinson’s disease

Purpose/Hypothesis: Parkinson’s disease (PD) occurs in 1 in 100 persons over the age of 65. Due to the nature of PD, persons with PD have many gait impairments, which increases the risk of falls. There are many approaches to address gait deviations in PD. It is unclear which intervention is superior when attempting to improve gait parameters. The purpose of this study is to determine if whole body vibration (WBV) produces larger improvements in gait parameters when compared to agility training for individuals with PD. The null hypothesis is there will be no difference between WBV and agility groups in gait parameters after intervention for individuals with PD. The alternative hypothesis was there will be a difference between groups in gait parameters.
