This study focused on designing and evaluating a bilateral semi-rigid hip exoskeleton. The exoskeleton assisted the joint, capitalizing its proximity to body’s center of mass. Unlike rigid counterparts, design permitted greater freedom movement. A temporal force-tracking controller allowed us prescribe torque profiles during walking. We ensured high accuracy by tuning control parameters series elasticity. evaluation involved experiments with ten participants across force profile conditions...
The introduction of women into U.S. military ground close combat roles requires research sex-specific effects training and operational activities. Knee osteoarthritis is prevalent among service members; its progression has been linked to occupational tasks such as load carriage. Analyzing tibiofemoral arthrokinematics during carriage important understand potentially injurious motion progression. study purpose was identify on knee walking running in recruit-aged women. Twelve healthy walked...
The power-duration relationship accurately predicts exercise tolerance for constant power performed in the severe intensity domain. However, accuracy of prediction time to task failure (Tlim) is currently unclear work rates (WR) above intensities; that is, within extreme domain (Tlim < 2 min). We hypothesized Tlim would be shorter WRs than predicted from linear 1/time which suggest mechanisms limiting are different between domains. Six men completed 7 knee-extension tests. (60%, 70%, 80%,...
Robotic rehabilitation has been shown to match the effects of conventional physical therapy on motor function for patients with neurological diseases. Rehabilitation robots have potential reduce therapists' workload in time-intensive training programs as well perform actions that are not replicable by human therapists. We investigated one such modality cannot be achieved a therapist: assistance and resistance within electromechanical delay between muscle activation contraction during arm...
INTRODUCTION: Critical mission tasks for Martian exploration have been identified and include specific duties that astronauts will to perform despite any adverse effects of chronic microgravity. Specifically, may an emergency capsule egress upon return Earth, which places demands on compromised cardiovascular neuromuscular systems. Therefore, the purpose this project was determine relationship between cardiorespiratory fitness simulated time. METHODS: There were 15 subjects who volunteered...
Abstract Metabolic cost greatly impacts trade-offs within a variety of human movements. Standard respiratory measurements only obtain the mean movement cycle, preventing understanding contributions different phases in, for example, walking. We present method that estimates within-stride walking by leveraging under force perturbations. The reproduces time series with greater consistency ( r = 0.55 and 0.80 in two datasets) than previous model-based estimations 0.29). This perturbation-based...
Peripheral artery disease (PAD) is characterized by reduced blood flow to the extremities due atherosclerosis. Studies report impaired gait mechanics in patients with lower extremity PAD. We hypothesized that revascularization surgery would improve when quantified net limb joint work across stance phase of walking. performed analyses 35 PAD and healthy, older adults. Patients a walking protocol prior six months following surgery. Healthy adults only took part single session. Lower powers...
