Practice, Dual-Task, Balance, Cerebral Stroke, AdultAbstract
Stroke is the most common and debilitating neurological condition in adults, leading to a decline in balance and functional dependence. Therefore, the aim of this study was to investigate the effect of dual-task training under constant and variable conditions on the balance of adults after experiencing a stroke. This study was a quasi-experimental design employing a pretest-posttest approach. The statistical population included adult individuals with a history of stroke who referred to medical centers in Shush Danial County. From among the volunteers, 30 participants were randomly selected and assigned to three groups: a control group, a dual-task training group under constant conditions, and a dual-task training group with variable prioritization. One week before the study began, the objectives, significance, and procedure of the research were explained to the participants, and informed consent forms were completed. The Berg Balance Scale and the Timed Up and Go Test were administered as pretests. Participants were then randomly assigned to three groups of ten, consisting of two experimental groups (dual-task training under constant conditions and dual-task training under variable conditions) and one control group. The experimental groups performed training sessions for four consecutive weeks, three 45-minute sessions per week. Data analysis using analysis of covariance and Bonferroni post hoc tests indicated that static and dynamic balance in adults post-stroke significantly improved following dual-task training under both constant and variable conditions (p ≤ 0.05). Based on the findings of this study, dual-task training methods under both constant and variable conditions can be utilized to enhance static and dynamic balance in adults with a history of stroke.
