Current Primary Outcome Measures
 (submitted: March 5, 2020)
  • ATPmax [ Time Frame: baseline ]
    Maximal mitochondrial ATP production rates measured by magnetic resonance spectroscopy
  • NAD(H) metabolites [ Time Frame: baseline ]
    Measurement of relative NAD(H) metabolite concentrations in resting skeletal muscle by magnetic resonance spectroscopy
  • Muscle force and endurance [ Time Frame: baseline ]
    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.
Original Primary Outcome Measures Same as current
Change History
Current Secondary Outcome Measures
 (submitted: March 5, 2020)
  • Mitochondrial metabolites [ Time Frame: baseline ]
    Separate measurement of NAD(H) metabolite concentrations in cytosol and mitochondria by magnetic resonance spectroscopy in resting skeletal muscle
  • Relationship between self report function and mitochondrial energetics [ Time Frame: baseline ]
    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.
  • Relationship between clinical assessment and mitochondrial energetics [ Time Frame: baseline ]
    Correlation between UPDRS with ATPmax and NAD(H) metabolites

Descriptive Information
Brief Title Measures of Mitochondria Dysfunction in PD
Official Title Functional and Metabolomic Biomarkers of Mitochondrial Dysfunction in Parkinson's Disease
Brief Summary 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.
Detailed 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.
