About

This study evaluates metabolic and functional parameters in the skeletal muscle of Parkinson's disease patients for comparison to a set of healthy age-matched controls.

Full description

The goal of this study is to identify the unique signature of bioenergetic markers and mitochondrial (dys)function in muscle of individuals with PD, who are 65-85 of age, read and speak English, have a Hoehn & Yahr score between 2 and 3 (bilateral disease, not severely disabled) and have a clinical diagnosis of PD. Bioenergetic markers and muscle functional properties will be compared to a control dataset collected over the last few years from healthy elderly subjects in the same age range to provide a foundation for future intervention studies.

Enrollment: 30 estimated patients

Sex: All

Ages: 65 to 85 years old

Volunteers: No Healthy Volunteers

Inclusion criteria
