Usefulness of the Dual-Task Stepping Test to Determine the Independent Toileting Ability of Patients with Stroke Who Could Perform Stepping in a Seated Position

: Introduction: This study aimed to identify the usefulness of the dual-task stepping test to determine the independent toileting ability of patients with stroke. Method: Sixty-seven stroke in-patients who were able to perform stepping in a seated position were enrolled in the study and underwent the dual-task stepping test. The relationships of the test results with other assessments (Berg Balance Scale, Mini-Mental State Examination, and the Attentional Rating Scale) with toileting ability, and with factors affecting toileting ability were investigated by regression analysis. Results: Patients with low dual-task performance tended to have poorer balance, attentional, and cognitive abilities. The results of the dual-task stepping test and rates of independent toileting were distributed as follows: severe dual-task disability, 15.6% (5/32), mild dual-task disability, 64.7% (11/17); and normal dual-task ability, 94.4% (17/18). The dual-task stepping test results revealed a significant relationship between dual-task disability and toileting ability ( p < 0.01). Logistic regression analysis showed that the dual-task stepping test had the highest odds ratio for toileting ability ( p = 0.00; odds ratio, 14.50). Conclusion: The dual-task stepping test was useful for determining independent toileting ability. This assessment is rapid and does not require special equipment or infrastructure, and has the potential for wide application in clinical practice.
