A randomized controlled trial of supervised versus unsupervised exercise programs for ambulatory stroke survivors

Area of Science:

• Neurology
• Rehabilitation Medicine
• Exercise Science

Background:

• Limited data exists on the comparative effectiveness of supervised versus unsupervised community exercise for stroke rehabilitation.
• Understanding long-term benefits and retention is crucial for optimizing post-stroke recovery programs.

Purpose of the Study:

• To compare the 10-week supervised exercise program with a 1-week supervised instruction followed by a 9-week unsupervised home program for stroke survivors.
• To evaluate the retention of physical improvements at 6 months and 1 year post-intervention.

Main Methods:

• 72 stroke survivors were randomized into supervised or unsupervised exercise groups.
• Primary outcome: 6-minute walking speed; Secondary outcomes: Human Activity Profile, SF-36, Physiological Cost Index, muscle strength.

Main Results:

• Both groups showed significant improvements in 6-minute walking speed, maintained at 1 year.
• Supervised group trended towards greater Human Activity Profile improvements; SF-36 scores improved significantly in both groups by 1 year.
• Gender differences observed: women gained more in supervised programs, men in unsupervised programs.

Conclusions:

• Supervised and unsupervised (post-instruction) exercise programs yield retained physical benefits for stroke survivors up to 1 year.
• Supervised programs may offer greater self-reported gains, warranting further investigation into gender-specific responses.
