A longitudinal study on physical activity in early Parkinson's disease

Area of Science:

• Neurology
• Movement Disorders
• Rehabilitation Medicine

Background:

• Physical activity (PA) is crucial for managing early Parkinson's disease (PD).
• Longitudinal studies on PA's impact in early PD are limited.
• Understanding PA's role in disease progression is essential for patient management.

Purpose of the Study:

• To longitudinally examine the effect of unprescribed physical activity on early Parkinson's disease symptoms.
• To assess the association between maintained PA levels and disease progression over five years.
• To identify PA's impact on motor symptoms, cognition, and quality of life in early PD.

Main Methods:

• Utilized data from an early Parkinson's Disease Cohort.
• Longitudinally analyzed reported physical activity levels over a five-year period.
• Controlled for demographic factors and medication use in the analysis.

Main Results:

• Physical activity significantly declined annually in early Parkinson's disease patients.
• Maintained physical activity was significantly associated with improved motor symptoms.
• Sustained PA correlated with better cognitive function and enhanced quality of life.
• Higher longitudinally maintained PA predicted slower progression of both motor and non-motor symptoms.

Conclusions:

• Consistent physical activity is associated with a slower disease progression in early Parkinson's disease.
• Maintaining physical activity positively impacts motor and non-motor symptoms.
• Physical activity is a key factor in improving and maintaining quality of life for individuals with early PD.
