Study investigated the effects of an 8-week rehabilitation exercise program combined with soymilk ingestion immediately after exercise on functional outcomes in chronic stroke patients.
Twenty-two stroke patients were randomly allocated to either the soymilk or the placebo (PLA) group and received identical 8-weeks rehabilitation intervention (3 sessions per week for 120 minutes each session) with corresponding treatment beverages. The physical and functional outcomes were evaluated before, during, and after the intervention. The 8-week rehabilitation program enhanced functional outcomes of participants.
The immediate soymilk ingestion after exercise additionally improved hand grip strength, walking speed over 8 feet, walking performance per unit lean mass, and 6-Minute Walk Test performance compared with PLA after the intervention. However, the improvements in the total score for Short Physical Performance Battery and lean mass did not differ between groups.
This study demonstrated that, compared with rehabilitation alone, the 8-week rehabilitation program combined with immediate soymilk ingestion further improved walking speed, exercise endurance, grip strength, and muscle functionality in chronic stroke patients.
