Effects Of A Passive Assistive Hamstring Device On Overground Running Kinematics And Hamstring Activation., Quinn Castner
Effects Of A Passive Assistive Hamstring Device On Overground Running Kinematics And Hamstring Activation., Quinn Castner
All Theses
Hamstring strain injuries are among the most common and recurring injuries in sports, occurring most often during the terminal swing phase of gait. Despite progress in rehabilitation, the incidence of injury has only increased, suggesting a need for a novel intervention. We designed a passive, assistive, wearable device with two specific criteria in mind: to offload the hamstrings during running, and do so without hindering normal kinematic patterns. The device consists of an adjustable elastic band anchored proximally at the waist and distally just above the ankle joint center. It stretches and shortens with the hamstrings, providing passive hip extension …
Development Of Low-Cost Triaxial Force Sensor For Measurement Of Human-Exoskeleton Interaction Forces, Hamdan Khan Sarvathullah
Development Of Low-Cost Triaxial Force Sensor For Measurement Of Human-Exoskeleton Interaction Forces, Hamdan Khan Sarvathullah
All Theses
Contemporary research suggests that shear force is a major contributor to discomfort and pressure injury. However, the variation of shear forces during human-exoskeleton interaction dynamics is a highly unexplored field. The high cost of commercial triaxial force sensors may be a major factor in the notable lack of research in this field. Therefore, in this paper, we present a low-cost, 3D-printed triaxial force sensor designed specifically to measure the triaxial interaction forces between an exoskeleton and its user. The triaxial force sensor uses Carbon-Black/Silicone Rubber (CB/SR) strings to measure shear forces, whereas the normal force is measured with a Force …
Development Of A Novel Predictive Model And Prosthetic System To Assess Dynamic Leg Length Based Gait Biomechanics In Lower Limb Prosthesis Users, Therese Parr
All Dissertations
Individuals with transfemoral amputation often rely on a prosthesis as a replacement for their missing extremity’s structure and function. Lower-limb prosthetic devices are developed with the goal of restoring biomechanical abilities and mitigating secondary health risks for users. However, biomechanical deficits for unilateral transfemoral prosthesis users are very common and are induced by both leg length discrepancy (LLD) and current prosthetic design shortcomings. Lack of push off power as well as difficulty shortening the leg for toe clearance can result in gait compensations that lead to asymmetric limb loading, increased muscle activity, and an increased incidence of falling due to …
