Associations Between Physical Activity Intensities and Physical Function in Stroke Survivors

Area of Science:

• Neurology
• Rehabilitation Medicine
• Exercise Science

Background:

• Stroke is a leading cause of disability in older adults.
• Physical activity is known to improve physical functioning.
• Limited research exists on the impact of different physical activity intensities on stroke survivors' physical function.

Purpose of the Study:

• To examine accelerometer-measured physical activity patterns in stroke survivors.
• To investigate the relationship between physical activity intensities and physical functioning.
• To assess the link between physical activity intensities and perceived functional limitations.

Main Methods:

• 30 stroke survivors (mean age 61.77) participated.
• Objective physical activity was measured using 7-day accelerometry.
• Physical functioning was assessed using the Short Physical Performance Battery and Late-Life Function and Disability Instrument.

Main Results:

• Higher moderate to vigorous physical activity correlated with better objective physical performance (Short Physical Performance Battery).
• Light physical activity predicted better self-reported function across all subscales of the Late-Life Function and Disability Instrument.
• Light physical activity showed significant positive associations with basic lower limb, advanced lower limb, upper limb, and total function.

Conclusions:

• Both light and moderate to vigorous physical activity contribute to improved physical functioning in stroke survivors.
• Light physical activity offers significant perceived functional benefits, crucial for individuals limited in higher intensity activities.
• Future interventions should consider incorporating both light-intensity and moderate to vigorous physical activity for stroke survivors.
