Title

PVAMC / OHSU D: The Effect of Vitamin D on Balance in Parkinson's Disease

Principal Investigator

Amie Hiller

Study Purpose

Previous studies have suggested that vitamin D supplementation decreases both fractures and falls in the elderly. People with PD are at higher risk of falling due to their motor problems. Despite medical therapy, 70% of persons with PD experience at least one fall per year. Falls can lead to fractures and other injuries, which can be costly to treat. If supplemental vitamin D prevents people with PD from falling so frequently, their quality of life will increase.

The main purpose of this study is to examine whether vitamin D supplementation improves balance in persons with Parkinson's disease (PD). We will also investigate whether vitamin D affects balance by improving muscle strength or mental abilities. Finally, we will evaluate whether vitamin D supplementation improves the quality of life for people with PD.
