Human walking dynamics are typically framed in the context of mechanics and energetics rather than in the context of neuromuscular control. Dynamic walking principles describe one helpful theoretical approach to characterize efficient human walking mechanics over many steps. These principles do not, however, address how such walking is controlled(More)
One of the adaptations of the Herbert bone screw (Zimmer Corp., Warsaw, Indiana) in podiatric surgery has been in the fixation of the Austin type osteotomy of the first metatarsal, to obtain rigid internal fixation. Technical difficulties in performing the procedure and complications have resulted in the development of several modifications of the original(More)
Human walking is a complex task, and we lack a complete understanding of how the neuromuscular system organizes its numerous muscles and joints to achieve consistent and efficient walking mechanics. Focused control of select influential task-level variables may simplify the higher-level control of steady-state walking and reduce demand on the neuromuscular(More)
This study presents a 3-year review of patients undergoing a fifth metaphyseal osteotomy for the treatment of Tailor's bunions. Postoperative analysis consisted of patient's subjective appraisal, activity level, physical examination, and radiographic studies. The fifth metaphyseal osteotomy, in this study, reduced lateral deviation and fourth-fifth(More)
This study compares modifications of Regnauld's enclavement procedure, the in situ "hat-shaped" and in situ "inverted" osteochondral graft. A 2-year retrospective analysis consisted of patients' satisfaction, activity level, first metatarsophalangeal joint range of motion, and radiographic evaluations. The result of this study demonstrates that both the(More)
Locomotor adaptation is commonly studied using split-belt treadmill walking, in which each foot is placed on a belt moving at a different speed. As subjects adapt to split-belt walking, they reduce metabolic power, but the biomechanical mechanism behind this improved efficiency is unknown. Analyzing mechanical work performed by the legs and joints during(More)
Minimizing whole body metabolic cost has been suggested to drive the neural processes of locomotor adaptation. Mechanical work performed by the legs should dictate the major changes in whole body metabolic cost of walking while providing greater insight into temporal and spatial mechanisms of adaptation. We hypothesized changes in mechanical work by the(More)
