Multidimensional effects of dual-task-focused training added to structured neurological rehabilitation in individuals with chronic stroke: a randomized controlled trial

Le résumé fourni par la source

Purpose. This randomized controlled trial aimed to investigate the multidimensional effects of dual-task-focused exercises added to structured neurological rehabilitation on balance, mobility, anxiety, cognitive function, and quality of life in individuals with chronic stroke. Materials and Methods. In this evaluator-blinded randomized controlled trial, forty individuals with chronic stroke were assigned to two groups. Both groups received six weeks of structured neurological rehabilitation, while the experimental group additionally completed dual-task training. Balance, walking speed, mobility, anxiety, verbal fluency, cognitive function, and quality of life were assessed before and after treatment. Results. Baseline demographic and clinical characteristics were similar between groups. Compared with controls, the dual-task group showed significantly greater improvements in mobility, anxiety, and quality of life, with particularly notable gains in anxiety and quality of life. Both groups improved in balance and cognitive function, with some measures favoring the control group. No significant between-group difference was found in walking speed. Conclusions. Adding dual-task-focused exercises to structured neurological rehabilitation provides significant benefits in mobility, anxiety, and quality of life in individuals with chronic stroke. Variability in balance and cognitive outcomes indicates the need for further research to determine optimal protocols and long-term effects.
