Natural Walking Intensity in Persons With Parkinson Disease

Area of Science:

• Neurology
• Kinesiology
• Physical Therapy

Background:

• Parkinson disease (PD) patients often do not achieve moderate-intensity walking for disease-modifying benefits.
• Understanding walking intensity and duration at lower levels is crucial for PD management.

Purpose of the Study:

• To describe the natural walking intensity and duration in ambulatory individuals with Parkinson disease.
• To provide insights into physical activity patterns in PD.

Main Methods:

• Observational study using accelerometer data from 82 participants in a PD clinical trial.
• Walking intensity categorized by steps per minute (1-19 to ≥100 steps).
• Analysis of daily walking minutes, longest sustained bout, and number of 10- to 30-minute bouts.

Main Results:

• Most daily walking occurred at low intensities (1-19 steps/min and 20-39 steps/min).
• The longest sustained walking bouts were at the lowest intensity (1-19 steps/min).
• Few walking bouts of 20 minutes or longer were observed across all intensities.

Conclusions:

• Individuals with Parkinson disease exhibit low-intensity walking patterns with short bout durations.
• Findings emphasize the necessity for targeted health promotion interventions to increase walking intensity in PD.
• Interventions should focus on increasing both the intensity and duration of walking for therapeutic effects.
