Dynamic Balance During Human Movement: Measurement and Control Mechanisms
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Walking can be exceedingly complex to analyze due to highly nonlinear multibody dynamics, nonlinear relationships between muscle excitations and resulting muscle forces, dynamic coupling that allows muscles to accelerate ...
Development of a Novel Perturbation Platform System for Balance Response Testing and Rehabilitation Interventions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Balance perturbations are often used to gain insight into reactive control strategies used to prevent falls. We developed a perturbation platform system (PPS) that can induce perturbations in both vertical and angled ...
Differences in Glenohumeral Joint Contact Forces Between Recovery Hand Patterns During Wheelchair Propulsion With and Without Shoulder Muscle Weakness: A Simulation Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The majority of manual wheelchair users (MWCU) develop shoulder pain or injuries, which is often caused by impingement. Because propulsion mechanics are influenced by the recovery hand pattern used, the pattern may affect ...
A Simulation Framework for Virtual Prototyping of Robotic Exoskeletons
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A number of robotic exoskeletons are being developed to provide rehabilitation interventions for those with movement disabilities. We present a systematic framework that allows for virtual prototyping (i.e., design, control, ...
Muscle Function and Coordination of Amputee Stair Ascent
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ascending stairs is challenging following transtibial amputation due to the loss of the ankle muscles, which are critical to human movement. Efforts to improve stair ascent following amputation are hindered by the limited ...
Muscle Function and Coordination of Stair Ascent
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stair ascent is an activity of daily living and necessary for maintaining independence in community environments. One challenge to improving an individual's ability to ascend stairs is a limited understanding of how ...
Muscle Contributions to Balance Control During Amputee and Nonamputee Stair Ascent
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic balance is controlled by lower-limb muscles and is more difficult to maintain during stair ascent compared to level walking. As a result, individuals with lower-limb amputations often have difficulty ascending ...
Selective Laser Sintered Versus Carbon Fiber Passive Dynamic Ankle Foot Orthoses: A Comparison of Patient Walking Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Selective laser sintering (SLS) is a wellsuited additive manufacturing technique for generating subjectspecific passivedynamic anklefoot orthoses (PDAFOs). However, the mechanical properties of SLS PDAFOs may differ from ...
Foot and Ankle Joint Biomechanical Adaptations to an Unpredictable Coronally Uneven Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Coronally uneven terrain, a common yet challenging feature encountered in daily ambulation, exposes individuals to an increased risk of falling. The foot-ankle complex may adapt to improve balance on uneven terrains, a ...
A Coronally Clutching Ankle to Improve Amputee Balance on Coronally Uneven and Unpredictable Terrain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To improve the balance of individuals with lower limb amputation on coronally uneven terrain, a coronally clutching ankle (CCA) was developed to actively adapt through ±15 deg of free coronal foot rotation during the first ...
