Stroke: a randomized trial of exercise or relaxation

Area of Science:

• Rehabilitation Medicine
• Neurology
• Geriatrics

Background:

• Stroke rehabilitation often focuses on regaining basic motor skills.
• The role of progressive exercise training in enhancing functional recovery and quality of life in ambulatory stroke survivors remains an area of investigation.

Purpose of the Study:

• To assess the feasibility of implementing a structured exercise training program for ambulatory stroke patients.
• To evaluate the effects of exercise training on physical function, daily activities, and health-related quality of life in this population.

Main Methods:

• A randomized exploratory trial compared progressive endurance and resistance training with a relaxation control group.
• Sixty-six independently ambulatory stroke patients, post-rehabilitation, participated in 12 weeks of thrice-weekly interventions.
• Outcome measures included functional assessments, mobility tests, physical fitness parameters, and quality of life questionnaires, assessed at baseline, 3 months, and 7 months.

Main Results:

• High adherence rates (94-99%) and attendance (median 36 sessions) indicated feasibility of the exercise program.
• The exercise group showed significant improvements in role-physical function, timed up-and-go, and walking economy at 3 months.
• At 7 months, role-physical function remained significantly better in the exercise group compared to the control.

Conclusions:

• Exercise training is a feasible and beneficial intervention for ambulatory stroke patients.
• This approach can lead to significant improvements in physical function and perceived health, positively impacting daily life.
• Further research can explore long-term effects and optimal exercise protocols for stroke recovery.
