The Safety, Feasibility, and Efficacy of a Structured Individual Exercise Program for Community-Dwelling Stroke Patients.

INTRODUCTION

Stroke is a leading cause of mortality and long-term disability worldwide, often resulting in low levels of physical activity post-discharge. A comprehensive exercise program could be a safe method to increase stroke patients' physical activity and exercise volume. This pilot study examines the effectiveness, safety, and feasibility of a comprehensive exercise regimen for stroke patients residing in the community after discharge.

METHODS

This single-group pilot study included patients who received inpatient rehabilitation for motor impairment following a stroke. Community-dwelling participants engaged in a comprehensive exercise program, which was structured and individualized, consisting of stretching, aerobic exercise, strength training, and balance exercises, conducted under the supervision of a health exercise specialist in a dedicated living lab within the hospital. The program involved 20 sessions, each lasting 50 min, conducted three to five times weekly. The pre- and post-intervention evaluations were comprehensive, including safety and validity assessments, along with physical function tests such as cardiopulmonary exercise testing and various fitness tests (6 min walk test, timed up and go test, chair stand test, figure-of-8 walk test, grip strength test, and sit-and-reach test). Depression levels were assessed using the Geriatric Depression Scale (GDS).

RESULTS

A total of 22 subjects were recruited, with 21 completing the study after one dropout due to fatigue and visiting distance. Among the 21 completers, one subject experienced a mild adverse event (hypoglycemia), which was not serious, confirming the program's safety. The exercise participation rate was 95.5%, and the adherence rate averaged 95.2%, with all completers achieving over 80% adherence. Significant improvements were observed in VO peak ( = 0.000), 6 min walk test ( = 0.000), timed up and go test ( = 0.000), chair stand test ( = 0.000), figure-of-8 walk test ( = 0.000), and grip strength ( = 0.001). However, changes in the peak respiratory exchange ratio ( = 0.078), sit-and-reach test ( = 0.228) and GDS scores ( = 0.275) were not significant.

CONCLUSION

This study demonstrates that the comprehensive exercise program is sufficiently safe and valid for stroke rehabilitation patients. The program significantly enhances cardiopulmonary endurance, walking ability, balance, muscle strength, muscle endurance, and coordination. Further research with larger sample sizes and control groups is needed to confirm these findings and explore additional benefits.
