Ab1187 reliability and Validity of the Cone Evasion Walk Test in Hip Osteoarthritis

Abstract

BackgroundHip osteoarthritis (OA) is associated with joint pain and stiffness, reduced balance, impeded mobility, and loss of functional independence [1]. Falls are the leading cause of fatal and nonfatal injuries among older adults and people with hip OA. Fall-related injuries and circumstances such as hip fractures and subsequent arthroplasty procedures put a significant burden on financial resources and healthcare systems [2]. Therefore, the identification and prevention of falls are easier, cheaper, and more effective for all parties in healthcare. The Cone Evasion Walk Test (CEW) is a dual-tasked performance measurement that was designed for evaluating dynamic balance, proactive gait control, and fall risk by assessing the ability to evade obstacles [3].ObjectivesThe aim of this study was to investigate the reliability and validity of the CEW in patients with hip OA and estimate the minimal clinically important difference (MCID) of the CEW.MethodsTwenty-seven patients with hip OA were included in this study. Patients performed trials for the CEW and the Timed up and Go Test (TUG). Between the CEW trials, patients got to rest for an hour.ResultsThe analysis showed that the CEW has excellent reliability and validity in hip OA (p<0.001). The relative (ICC coefficient) and absolute (SEM and SRD95) reliability of the CEW were 0.95, 0.53, and 1.46 respectively. The Spearman correlation coefficient with the TUG was 0.65.ConclusionThe CEW was shown to be effective in terms of evaluating the function, dynamic balance, mobility, and fall risk with an additional attention-demanding task in patients with hip OA. The low MCID value (1.46) provides a sensitive measure of alterations in a patient’s condition. Therefore, the CEW may be a better assessor of the proactive gait control, fall risk, mobility, and dynamic balance activities in the everyday community than the existing performance measures.References[1]Smith TO, Higson E, Pearson M, Mansfield M.
