Walking speed increased between trials, but SPARC outcomes were stable across trials and not influenced by speed. a, b Walk 1 phase showed increased speed between trials, likely reflecting learning of the task. Both walking phases were slower for subjects with PD. c SPARC outcomes during the walk 1 phase showed absence of trial effects, suggesting independence of walking speed. Data is mean ± confidence interval 95% in a and b (middle panels) and Mean (other panels); nControl = 6; nPD = 31; *p < 0.05
