Pushing the limit to reach meaningful change: the impact of intensity-driven exercise on clinical outcomes for individuals with Parkinson’s disease. A single-subject design

Parkinson's disease creates an inability to perform previous learned autonomic tasks, such as walking, which worsens with disease progression. Recommendations to incorporate exercise at moderate to high intensities for this population has been established but there is limited knowledge about its impact on clinical based outcomes. The purpose of this research is to investigate the effectiveness of a 6-week intensity-driven walking program on clinical-based outcomes in individuals with PD.
