Abstract Objective: To test the reliability, validity and responsiveness of 3-meter backward walk test (3MBWT) in the evaluation of dynamic balance function in stroke patients. Methods: From December 2020 to June 2021, 40 stroke patients from the Second Affiliated Hospital of Wenzhou Medical University completed 3MBWT, Berg Balance Scale (BBS), the timed up and go test (TUGT) and modified Barthel Index (MBI) for Spearman correlation analysis. Two researchers completed the 3MBWT of the same patient separately. One of the researchers retested the 3MBWT of the same patient 2 hours later and calculated the intraclass correlation coefficient (ICC). After one week of treatment, 3MBWT, BBS and TUGT were retested in 40 patients to compare the reactivity of the three tools. Results: The retest ICC of 3MBWT was 0.889 and the inter-rater ICC was 0.998; 3MBWT was strongly correlated with BBS (r=-0.854, P<0.001), TUGT (r=0.872, P<0.001), and 3MBWT was moderately correlated with MBI (r=-0.519, P<0.001). The order of |ES| and |ERM| values is 3MBWT>TUGT>BBS. Conclusion: 3MBWT has good reliability, validity and reactivity in evaluating dynamic balance function in stroke patients.
