Figure 3From: Aging and selective sensorimotor strategies in the regulation of upright balanceSingle-session adaptation of muscle responses. EMG latencies (mean ± S.D.) of ventral muscles responding to toes-up pitch surface perturbations across young (gray circles) and old subjects. Note the decrease in the latencies in old subjects from the first 10 (black diamonds) to the last 10 (open triangles) trials.Back to article page
