Gait-related spectral perturbations across stages of split-belt treadmill adaptation
<p>This mobile brain body imaging experiment used high-density electroencephalography to investigate brain activity correlated to gait adaptation during split-belt treadmill walking. 30 participants completed an abrupt split-belt walking paradigm (2:1 belt speed ratio). Videos show gait-related spectral perturbations across stages of split-belt adaptation in group component clusters near the sensorimotor, posterior parietal, and cingulate cortices. </p>
Adapting spatiotemporal gait symmetry to electrical stimulation during treadmill walking
<p>Individuals with neurological impairments often exhibit asymmetrical gait patterns. This study highlighted the potential of functional electrical stimulation (FES) to improve gait symmetry during treadmill training and investigated whether our proposed FES perturbation paradigm could induce gait adaptation concerning spatial and temporal gait symmetry in healthy subjects. In the FES perturbation paradigm, both legs received electrical pulses at the same period as the subjects' initial stride duration, and the temporal gap between the two pulses for each leg was manipulated over 7 minutes. Following this, subjects continued to walk for another 5 minutes without FES. For the implicit trial (unconscious reaction to FES), subjects were asked to walk comfortably in response to the stimulation. For the explicit trial (conscious reaction to FES), subjects were asked to explicitly synchronize their toe-off phase to the stimulation. To examine the effects of the FES perturbation, we measured step length and stance time and then analyzed changes in step length and stance time symmetries alongside their subsequent aftereffects. In this study, regardless of whether subjects adapted their gait patterns to the electrical pulses explicitly or implicitly, a directional change was observed in stance time (temporal) symmetry under both conditions, with the right stance becoming longer than the left. The stance time asymmetry induced by FES perturbation resulted in a slight residual effect. No consistent trend of step length (spatial) symmetry changes was observed in either condition. This indicates that subjects may adapt their spatial gait patterns through diverse mechanisms. Our findings suggest that the applied FES perturbation strategy can induce adaptations in subjects' temporal gait asymmetry, particularly while in stance. Further experiments would provide a deeper understanding of the mechanism behind subjects' response to FES perturbations, as well as the long-term effects of these perturbations on the spatial and temporal aspects of gait symmetry.</p>
Dataset and analyses for : Can foot placement during gait be trained? Adaptations in stability control when ankle moments are constrained
<p>Here you'll find the dataset and analyses belonging to the publication "Can foot placement during gait be trained? Adaptations in stability control when ankle moments are constrained". Participants walked on a treadmill with and without shoes constraining ankle moment control. We evaluated whether participants improved their degree of foot placement control, during and after walking with ankle moment constraints. Ground reaction forces and full body kinematics have been collected.</p> <p>For more detail on the folders' contents please see "Read me - Can foot placement during gait be trained.docx".</p>
