Aim: The Dubousset Functional Test (DFT) ia a practical four-component assessment test to assess the physical function and balance capacities. The study aimed to examine the reliability, validity, responsiveness of the DFT in stroke survivors. Methods: This study included a total of 57 post-stroke patients (age 60.16 ± 15.08 years). The participants were divided into two groups according to the duration of stroke (6–12 months, 12 months and more). Reliability of DFT test was evaluated with Intraclass Correlation Coefficient (ICC). The correlation between the DFT and The Timed Up and Go test (TUG), dual-task TUG, Functional Reach Test (FRT), 3-meter backward walk test (3MBWT), Tinetti Performance Oriented Mobility Assessment (POMA) was used for the validity. Results: For total post-stroke patients, ICC values were between 0.899 and 0.984 (excellent agreement). For stroke patients have 6–12 months stroke duration ICC values were between 0.831 and 0.988 (excellent agreement). For post-stroke patients have 6–12 months stroke duration ICC values were between 0.858 and 0.992 (excellent agreement). For total stroke post-patients the correlation with four component of DFT and TUG, dual-task TUG, FRT, 3MBWT and POMA was found to be statistically significant (p < 0.001). Conclusion: The DFT has excellent reliability and validity in post-stroke patients. Therefore, it may be a clinically suitable test for detecting balance and physical function.
