Modular organization across changing task demands in healthy and poststroke gait.

Routson RL, Kautz SA, Neptune RR - Physiol Rep (2014)

Bottom Line: The number of modules required to account for >90% of the variability accounted for the EMG patterns of each muscle was found using nonnegative matrix factorization.Mobility performance measures of task capability were speed change, cadence change, step length change, and step height change.However, this adaptability in module timing, in addition to mobility capability, is limited in poststroke subjects.

fig01: Region definitions over the gait cycle.

Mentions: To assess the differences in module timing, each module's activation timing was integrated over 100% of the gait cycle and then the percentage of the total integrated module activation timing was calculated for six regions of the gait cycle (Fig. 1; Nott et al. 2014). For each of the four groups of subjects separate one‐way ANOVAs (P < 0.05) and post hoc t‐tests with Bonferroni corrections were used to compare the percentage of the total integrated module activation timing for each of the six regions of the gait cycle across the mobility capability tasks.
