Parkinson Disease, Mitochondrial Clinical Trial
Official title:
Functional and Metabolomic Biomarkers of Mitochondrial Dysfunction in Parkinson's Disease
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.

---|---|---|---|---|
Primary | ATPmax | Maximal mitochondrial ATP production rates measured by magnetic resonance spectroscopy | baseline | |
Primary | NAD(H) metabolites | Measurement of relative NAD(H) metabolite concentrations in resting skeletal muscle by magnetic resonance spectroscopy | baseline | |
Primary | Muscle force and endurance | Maximum voluntary contraction (MVC) force in Newtons and fatigue resistance assessed by the ability to maintain repeated contractions at 70% MVC will be measured in the hand (flexor digitorum interroseus) and leg (tibialis anterior) using isometric contractions in a custom made apparatus. | baseline | |
Secondary | Mitochondrial metabolites | Separate measurement of NAD(H) metabolite concentrations in cytosol and mitochondria by magnetic resonance spectroscopy in resting skeletal muscle | baseline | |
Secondary | Relationship between self report function and mitochondrial energetics | Correlation between self report of fatigue, balance, and muscle pain (PRO-PD) with ATPmax rates and NAD(H) metabolite concentrations measured using magnetic resonance spectroscopy. | baseline | |
Secondary | Relationship between clinical assessment and mitochondrial energetics | Correlation between UPDRS with ATPmax and NAD(H) metabolites | baseline |
