Trial Outcomes & Findings for Vibration Impact on Parkinson's Tremor (NCT NCT03799614)

NCT ID: NCT03799614

Last Updated: 2020-12-17

Results Overview

The "Movement Disorder Society Unified Parkinson Disease Rating Scale" (MDS-UPDRS) Part III, only, will be used at baseline, and repeated during vibration and post vibration data collection times. It is a validated scale administered by a clinician, contains 34 items to score between 0 (normal) and 4 (severe). The score range is 0 - 136. It takes \~ 5 minutes to complete. Lower scores are better. This outcome measure will be used to report a change in PD motor symptoms over time.

PRIMARY outcome

Timeframe: Data collection times were baseline, 5 minutes after vibration start (vibration duration was 20 minutes), 5 minutes after vibration was stopped. .

Clinical Rating Scale for Tremor (Fahn, Tolosa, \& Marin) assesses severity of tremor symptoms. This scale takes 10-minutes, Items 1 - 14 will be used to report average changes in tremor. Items are rated on a scale of 0=normal to 4=severely abnormal, total summative score range for items 1- 14 points is 0 - 56. Lower scores are better. Total time to complete the Scale for Tremor assessment is 10 minutes.
