Acute Effects of Whole Body Vibration for Individuals With Parkinson Disease

Not Applicable

Completed

• Conditions: Parkinson Disease

• Registration Number: NCT06352905
• Lead Sponsor: Baylor University

Brief Summary

This is an exploratory study to assess the impact of whole body vibration on backward walking speed in people with Parkinson disease.

Detailed Description

This study will provide valuable information towards the relationship between backward walking using the 3-minute backward walk test and whole body vibration (WBV). The 3MBWT has shown to have diagnostic accuracy for fall prediction in older adults. The 3MBWT has been found to be feasible within the acute stroke population. In a study, the 3MBWT revealed that in the geriatric population a score of more than 4.5 seconds were likely to report a fall history. Gait parameters including a decrease in gait velocity (p\<0.01) have been found to worsen while performing dual tasks (serial-7 subtraction) in individuals with PD. Research has shown when compared to other cognitive tests, the "serial sevens" tests increased the time required to perform the Timed Up and Go in individuals with PD.

This study will use a control group performing mid-squats on level ground and an intervention group performing mid-squats on a WBV machine. Each group will perform 5 sets of mid-squats for 60 seconds with a 60 second rest period between each set. Pre and post testing will involve three trials of the 3MBWT.

The purpose of this study is to determine the immediate impact of WBV on backward walking velocity in individuals diagnosed with PD.

Primary Outcome Measures

Name	Time	Method
3-meter backward walk test (3MBWT)	5 minutes	The 3MBWT has excellent intrarater reliability as a backward walking velocity assessment. This standardized measure demonstrates diagnostic accuracy for predicting falls within a year in healthy older adults and people with Parkinson disease. Participants stand with their heel touching a line of tape on the floor and are instructed to initiate backward walking at the verbal cue "start" and to continue until instructed to stop (3 meters) by the tester guarding. The average of 3 trials is the score.
