INTRODUCTION: Limb-girdle muscular dystrophies (LGMDs) are neuromuscular and genetic disorders that progress with weakness and damage of the proximal muscles, developing with loss of functionality. Virtual reality environments are suggested as an effective alternative for performance of daily life activities. However, there is no evidence in the literature on the use of virtual reality in this populationOBJECTIVE: Assess motor performance through a motor learning protocol in a coincident timing taskMETHODS: 10 participants with LGMD and 10 healthy individuals were selected and included in the study to perform a non-immersive virtual reality task divided into three phases: acquisition (20 attempts), retention (5 attempts), and transfer (5 attempts, with speed increaseRESULTS: It is observed that the accuracy of movement improves from the beginning to the end of the acquisition (p = 0.01); however, there is a marginal difference between the groups in block A1 (p = 0.089). Regarding the variability of touches, observed by the variable error, both groups improved performance in all phasesCONCLUSION: Even with lower performance than the control group at the beginning of the practice, individuals with LGMD showed the potential to optimize motor function during the practice of a non-immersive virtual reality activity and were able to match their performance with the control group after a few attempts
