Purpose: Osteoarthritis of the knee (KOA), which is a common condition in modern times, increasesthe risk of falls and causes the injuries. Therefore, development and implementation of fall riskassessment tests for patients with KOA, who represent a significant proportion of population, is veryimportant. Some tests are available to assess fall risk, but these tests cannot assess backward walking,which requires more neuromuscular control and reveals mobility deficits relatively early. This studyaimed to determine concurrent validity and test-retest reliability of 3-Meter Backward Walking Test(3MBWT) in patients with KOA.Methods: A total of 41 patients with KOA (61.18±10.61 years), 37 of whom were women, participatedin the study. In order to examine test-retest reliability, 3MBWT was administered twice during firstevaluation, and mean score was recorded. One week later, same procedure was repeated. The resultswere analysed using intraclass correlation coefficient and Bland Altman analysis. To determine validity,relationship between Timed-Up and Go-Test (TUG), Knee Injury and Outcome Score (KOOS),Modified Fall Efficacy Scale (MFES), and 3MBWT were evaluated by spearmen correlation test.Results:Test-retest reliability was found to be 'good'(ICC:0.890). A strong correlation(r=0.810) wasfound between 3MBWT and TUG, whereas a moderate negative correlation was found between3MBWT and MFES(r=-0.678). Negative correlations ranging from -0.717(KOOS-pain) to -0.527(KOOS-recreation) were found between KOOS-subscales and 3MBWT.Conclusions: 3MBWT is a valid and reliable performance test for people with KOA. Clinical use ofthis test can provide important and practical information about functional status and fall risk of patients.Keywords: Gait, Falls, Knee Osteoarthritis, Performance-based test, Reliability, Validity
