Objective: To verify the interval of responsiveness to the scales Segmental Assessment of Trunk Control (SATCo-BR), Performance of Upper Limbs (PUL), and Jebsen Taylor Test (JTT) in patients with Duchenne Muscular Dystrophy (DMD). Methods: We assessed patients with DMD aged 6 to 19 years old and with mini-mental (MMSE) score above 10 points. The assessments were performed individually, in a single session. The upper limb function was performed by PUL and JTT, and trunk control by SATCo-BR. Assessments were repeated six and 12 months after the initial assessment. The repeated-measures analysis of variance model and Bonferroni’s multiple comparison method were employed as post hoc analysis; when the ANOVA assumptions were not met, the Friedman test was applied. Results: The sample consisted of 28 patients evaluated in three moments (initial, and six and 12 months after the beginning). There was a time effect for the Upper Limb function performance in the total JTT, and for the subtests, except for subtests 1 and 6, which did not show a difference between the different moments. There was also a time effect for the score of total PUL, proximal PUL, intermediate PUL, and distal PUL. In the SATCo-BR, this effect was observed between the initial and 6 months, and between the initial and 12 months. Conclusions: The JTT, PUL, and SATCo-BR scales can detect changes over time, and they showed responsiveness to detect the evolution of the disease in the 6-month interval.
