The influence of induced gait asymmetry on joint reaction forces


By: E. McCain*, M. Dalman n, M. Berno n, T. Libera n, M. Lewek*, G. Sawicki*, K. Saul n

author keywords: Musculoskeletal modeling; Simulation; Joint restriction; Joint reaction force
MeSH headings : Humans; Gait / physiology; Knee Joint / physiology; Lower Extremity / physiology; Knee; Walking / physiology; Biomechanical Phenomena
TL;DR: While joint restriction results in increased limb loading, reductions in muscle forces counteract changes in limb loading such that JRFs were relatively unchanged, similar to other JRFs investigated. (via Semantic Scholar)

Isolating the energetic and mechanical consequences of imposed reductions in ankle and knee flexion during gait


By: E. McCain n, T. Libera n, M. Berno n, G. Sawicki*, K. Saul n & M. Lewek*

author keywords: Biomechanics; Gait; Ankle; Knee; Metabolic cost
MeSH headings : Adaptation, Physiological / physiology; Adult; Ankle; Ankle Joint / physiology; Biomechanical Phenomena; Female; Gait / physiology; Humans; Knee Joint / physiology; Male; Range of Motion, Articular / physiology; Walking; Young Adult
TL;DR: As expected, reduced ankle motion, either without ( restricted-ank) or in addition to knee restriction (restricted-a + k) yielded significant increase in net metabolic rate when compared with the braced condition, and the relative increase in metabolic cost was significantly larger with restricted-a'+’k when compared to restricted-knee condition.

Reduced joint motion supersedes asymmetry in explaining increased metabolic demand during walking with mechanical restriction


By: E. McCain n, M. Berno n, T. Libera n, M. Lewek*, G. Sawicki* & K. Saul n

author keywords: Gait; Asymmetry; Metabolic cost; Degrees of freedom; Joint restriction
MeSH headings : Ankle Joint; Biomechanical Phenomena; Gait; Humans; Knee Joint; Walking
TL;DR: The results emphasize symmetry is not by definition metabolically optimal, indicate that the mechanics underlying symmetry are meaningful, and suggest that available degrees of freedom should be considered in designing future interventions. (via Semantic Scholar)

Mechanics and energetics of post-stroke walking aided by a powered ankle exoskeleton with speed-adaptive myoelectric control


By: E. McCain n, T. Dick*, T. Giest n, R. Nuckols*, M. Lewek*, K. Saul n, G. Sawicki*

author keywords: Ankle mechanics; Exoskeleton; Trailing limb angle; Propulsion; Myoelectric control; Electromyography; Metabolic cost; Hemiparesis; Stroke rehabilitation; Walking
MeSH headings : Adult; Ankle Joint / physiology; Biomechanical Phenomena / physiology; Electromyography / methods; Exoskeleton Device; Female; Humans; Male; Middle Aged; Stroke Rehabilitation / instrumentation; Walking / physiology; Walking Speed / physiology
TL;DR: The results suggest that despite appropriate scaling of ankle assistance by the exoskeleton controller, suboptimal limb posture limited the conversion of exoskeletons assistance into forward propulsion. (via Semantic Scholar)

Spatial Dependency of Glenohumeral Joint Stability During Dynamic Unimanual and Bimanual Pushing and Pulling


By: D. McFarland n, E. McCain n, M. Poppo n & K. Saul n

TL;DR: Stability benefits to task placement for pushing and pulling were limited, and larger stability benefits may be seen from converting pushing to pulling rather than optimizing task layout. (via Semantic Scholar)
