Evidence of Implicit and Explicit Motor Learning during Gait Training with Distorted Rhythmic Auditory Cues
Duppen, C. P., Wrona, H., Dayan, E., & Lewek, M. D. (2023, June 29). JOURNAL OF MOTOR BEHAVIOR.
author keywords: motor learning; gait training; error-based learning; implicit learning
TL;DR:
Despite evidence of both implicit and explicit processes involved with each metronome, there were no between-condition differences in implicit or explicit retention for cadence, step length, or gait speed, and thus no increased implicit learning advantage with the addition of error-based recalibration for young, unimpaired adults.

The influence of induced gait asymmetry on joint reaction forces
JOURNAL OF BIOMECHANICS, 153.
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

Isolating the energetic and mechanical consequences of imposed reductions in ankle and knee flexion during gait
JOURNAL OF NEUROENGINEERING AND REHABILITATION, 18(1).
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
JOURNAL OF BIOMECHANICS, 126.
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.
