Biomechanics Research

KEY FINDING: Motor and sensory scores were significantly different between the ambulators and non-ambulators. The majority was associated to the function of lower extremities.

KEY FINDING: Reciprocating activation patterns of quadratus lumborum, latissimus dorsi, pectoralis major, and lower trapezius are responsible for trunk extension during balance adjustment, leg unloading, and propulsion force generation.

KEY FINDING: Although not significant (P = .23), the Borg RPE scores for the SC condition were consistently higher than the scores for the P condition.

KEY FINDING: Persons with iSCI exhibited greater kinematic variability than controls, which scaled with deficits in overground walking speed.

KEY FINDING: Mobile, real-time, verbalized feedback is feasible and results in a normalization of the feedback gait parameter.

KEY FINDING: Quadratic models based on walking speed had the strongest correlations with sagittal kinematic and kinetic gait parameters, with kinetic parameters having the better results.

KEY FINDING: Participants decreased push frequency and increased contact angle after the practice sessions.

KEY FINDING: Controls proportionally adjusted temporal parameters, single joint trajectories, and intralimb coordination to unloading levels, while spatial parameters were unaffected.

KEY FINDING: SCI patients exhibited slower walking speeds, longer stride and stance times, and shorter stride lengths compared to healthy subjects.

KEY FINDING: Participants with iSCI showed decreased COM movement variability with practice, indicating improved motor control during transitions.
