From this study, High-intensity strength training shows benefit for Parkinson’s patients comes this quote:
"High-intensity strength training produced significant improvements in quality of life, mood and motor function in older patients with Parkinson’s disease…“We saw improvements in strength, muscle size and power, which we expected after rigorous weight training; but we also saw improvement in balance and muscle control, We also saw improvement in cognition, mood and sense of well-being.”
At Austin Personal Training and New Orleans Personal Training we have worked with Parkinson patients. We use primarily medical rehab equipment and can finely tune the weight and range of motion to those with limitations.
