Effectiveness of a self-rehabilitation program to improve upper-extremity function after stroke in developing countries: A randomized controlled trial.

BACKGROUND: About two-thirds of stroke patients present long-term upper-limb impairment and limitations of activity, which constitutes a challenge in rehabilitation. This situation is particularly true in developing countries, where there is a need for inexpensive rehabilitation solutions. OBJECTIVE: This study assessed the effectiveness of a self-rehabilitation program including uni- or bi-manual functional exercises for improving upper-limb function after stroke with respect to the context in Benin, West Africa. METHODS: In this single-blind randomized controlled trial, chronic stroke individuals (>6 months post-stroke) performed a supervised home-based self-rehabilitation program for 8 weeks (intervention group); the control group did not receive any treatment. Participants were assessed before treatment (T0), at the end of treatment (T1) and 8 weeks after the end of treatment (T2). The primary outcome was the manual ability of the upper limb, assessed with ABILHAND-Stroke Benin. Secondary outcomes were grip force, motor impairment (Fugl-Meyer Assessment - Upper Extremity), gross manual ability (Box and Block test, Wolf Motor Function test) and quality of life (WHOQOL-26). RESULTS: We included 28 individuals in the intervention group and 31 in the control group. Adherence to the program was 83%. After 8 weeks of self-rehabilitation, individuals in the intervention group showed significantly improved manual ability and grip force as compared with the control group (P<0.001), with effect size 0.75 and 0.24, respectively. In the intervention group, the difference in average scores was 10% between T0 and T1 and between T0 and T2. Subscores of physical and psychological quality of life were also significantly improved in the intervention group. The other variables remained unchanged. CONCLUSIONS: A self-rehabilitation program was effective in improving manual ability, grip force and quality of life in individuals with stroke in Benin. More studies are needed to confirm these results in different contexts.

Feasibility of a self-rehabilitation program for the upper limb for stroke patients in Benin.

INTRODUCTION: Stroke is a major cause of disability and represents a very high cost in developing countries. Self-rehabilitation programs represent a new and original treatment for stroke patients, likely to reduce upper limb impairments and improve activity and participation. The goal of this study is to evaluate the feasibility of a self-rehabilitation protocol in Benin. METHODS: Twelve chronic stroke patients carried out the upper limb self-rehabilitation program (3 hours/day, 5 days/week for 2 weeks). The performance of these patients was evaluated before and after the self-rehabilitation program, by measuring the number of exercises that patients were able to achieve during a three-hour session, and by assessing their gross manual dexterity. RESULTS: Twelve patients were effectively able to complete the entire program. The number of unimanual exercises and self-mobilizations performed during a three-hour session as well as the score of the Box and Block test were improved by the self-rehabilitation program (P<0.05). DISCUSSION AND CONCLUSION: Self-rehabilitation programs are feasible and inexpensive as they do not involve a therapist. It is then a promising approach in stroke rehabilitation, particularly in developing countries, where rehabilitation costs are usually supported by patients.
