The 3-Meter Backward Walk Test in Individuals With Multiple Sclerosis

The 3-m backward walk test (3MBWT) is used to evaluate neuromuscular control, proprioception, protective reflexes, fall risk and balance. The aim of our study was to reveal the test-retest reliability and validity of the 3MBWT in Multiple Sclerosis patients. Our study will be done as a \"test-retest\" design and psychometric properties of 3 m backward walking test in MS patients will be examined. Mini Mental State Examination, 3 m walk back test, Berg Balance Scale, Timed Up and Go, Timed 25 Step Walking Test and 4-Square Step Test will be applied to the patients. All evaluations will be made by the same physiotherapist. The second and third evaluation (retest) will be performed by the same physiotherapist two days after the first evaluation (test) and 2 weeks later to measure test-retest reliability. It will be preferable to collect data with the same evaluator to avoid inter-rater error rate between evaluations. It will be preferable to collect data with the same evaluator to avoid inter-rater error rate between evaluations. The sample size, according to Lexell and Downham (2005), 40-50 participants should be included in reliability studies. Considering this recommendation, which defines the reliability of 3MBWT, it is planned to include 50 individuals with MS in our study.
