2 Clinical Trials for Various Conditions
Postherpetic Neuralgia is a painful nerve condition that can occur when nerve fibers are damaged following an outbreak of shingles. The purpose of this study is to identify and study abnormalities in the nerves and cells in the of patients with postherpetic Neuralgia (PHN) and characterize changes that could be responsible for causing nerve pain. This data will be compared to the tissue of healthy volunteers. Our goal is that this information will lead to the development of better treatment options for people with painful nerve conditions.
The purpose of this study is to learn more about balance and strength in an elderly population (60 and older). Data will be compared between controls and the age/gender- matched PD participants in study "The Effects of vitamin D on Balance in Parkinson's disease" (OHSU IRB # 6482). Specifically a t-test will be used to compare total work and total power on leg extension and flexion, composite SOT score conditions 1-3 and 4-6, response strength and latency on MCT, and turn duration from the iMOBILITY between the two groups.
