The specific training based on perturbationswas developed to evaluate balance stability recovery after unpredictable displacements of the support base in the mediolateral direction. The effects of block and random sequences were developed to compare different schedules of postural perturbations on the acquisition of stability of arm and leg compensatory movements in healthy young individuals. The task consisted in recovering body balance after unpredictable perturbations through support base displacements in mediolateral direction, for both sides in different speeds (20, 30 e 40 cm/s [º/s]). The groups performed a single session with 24 practice trials for each of the following modalities of postural perturbation: rotation, translation and combination translation-rotation. The control group allowed the evaluation of the first responses to postural perturbations was used as a baseline of postural responses without training for comparison with the experimental groups. Participants were evaluated in post-test, retention and transfer to the following contexts: (1) dual task, of counting down during perturbations; and (2) speed higher than those trained (50 cm/s [º/s]). The compensatory arm and leg movements were evaluated using the CALM scale and kinematics (dx.doi.org/10.17504/protocols.io.2p2gdqe).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
