Abstract: 

Study investigated how stroke survivors generate symmetric steps and explored how the resulting gait pattern may relate to the metabolic cost of transport. Kinematic, kinetic, and metabolic data were recorded as nine individuals with stroke walked on an instrumented treadmill under two conditions: preferred walking and symmetric stepping (using visual feedback). Gait kinematics and kinetics remained markedly asymmetric even when stroke survivors improved step-length symmetry. Impaired paretic propulsion and aberrant movement of the center of mass (COM) were evident during both preferred walking and symmetric stepping. These deficits contributed to diminished positive work performed by the paretic limb on the COM in both conditions. Within each condition, decreased positive paretic work correlated with increased metabolic cost of transport and decreased walking speed across participants. It is critical to consider the mechanics used to restore symmetric steps when designing interventions to improve walking after stroke. Future research should consider the many dimensions of asymmetry in post-stroke gait, and additional within-participant manipulations of gait parameters are needed to better understand the elevated metabolic cost of walking after stroke.
