BACKGROUND AND PURPOSE: The purpose of this study was to investigate the 3-meter backward walk test (3MBWT) in individuals with Parkinson Disease (PD) to determine the following: (1) concurrent validity with other gait velocity measures and (2) interrater and intrarater reliability of in-person and video assessment. METHODS: A convenience sample of 25 people with PD participated. Forward gait velocity was measured using a computerized walkway (Zeno Walkway System), the 10-meter walk test (10MWT), and 4-meter walk test (4MWT). Backward gait velocity was measured using the 3MBWT. Concurrent validity was assessed using Pearson's correlations. Reliability was assessed using intra-class correlation coefficients (ICC RESULTS: All relationships between the 3MBWT and gait outcome measures were significant. The 3MBWT demonstrated strong correlations with the 4MWT dual task ( CONCLUSION: The 3MBWT demonstrates validity and reliability as a tool for assessing gait speed in the posterior direction in people with PD.
