Relationship between Dual-task Timed Up and Go test and Clinical Outcomes in Patients with Chronic Dizziness/Vertigo

Abstract

The purpose of this study was to determine the relationship between the results of the dual-task Timed Up and Go test and the clinical outcomes in patients with chronic dizziness/ vertigo.A total of 18 patients with dizziness/vertigo were included in the study. The patients were evaluated by the Timed Up and Go test (TUG), dual-task Timed Up and Go test (TUGdt), Dizziness Handicap Inventory (DHI), Activities-Specific Balance Confidence Scale (ABC scale), Dynamic Gait Index (DGI), and Functional Gait Assessment (FGA). The difference between the results of TUG and TUGdt was defined as ΔTUG. We analyzed the correlation between the results of each evaluation using Pearson product-moment correlation and Spearman's rank correlation coefficient.Significant correlations were found between the results of TUG-TUGdt, TUG-FGA, TUGdt-ΔTUG, ΔTUG-ABC scale, and DGI-FGA.Dual task during gait was found to be related to the self-efficacy in activities of daily living. Dual task during gait could be influenced by psychological factors. TUGdt may be useful to assess the gait performance reflecting psychological aspects. 原 著慢性期めまい平衡障害患者における Dual-task Timed Up and Go test と 臨床指標の関連 荻原 啓文 １) ２) ・加茂 智彦 ２) ３) ・田中 亮造 ２) ４) ，加藤 巧 ２) ・浅見 正人 ２) ３) 遠藤まゆみ ２) ・角田 玲子 ２) ５) ，伏木 宏彰 ２) ５)
