An ankle exosuit tuned to the measured muscle dynamics of user during multiple walking tasks improves energy economy.
In individuals with motor impairments such as those post-stroke or cerebral palsy, the function of knee extensors may be affected during walking, resulting in decreased mobility. We have designed a lightweight, hinge-free wearable robot combining soft textile exosuit components integrated rigid components, which assists extension when needed but is otherwise highly transparent to wearer. The can apply wide range assistance profiles using flexible multi-point reference trajectory generator....
Abstract As we age, humans see natural decreases in muscle force and power which leads to a slower, less efficient gait. Improving mobility for both healthy individuals those with impairments/weakness has been goal exoskeleton designers decades. In this work, discover that significant reductions the energy cost required walking can be achieved almost 50% mechanical compared state of art. This was by leveraging human-in-the-loop optimization understand importance individualized assistance hip...
People with tetraplegia resulting from spinal cord injury experience debilitating hand impairments that may lead to lifelong dependence on others perform activities of daily living. Wearable robotic devices actively support function during living tasks could bring great benefits this population. In work, the performance a textile-based soft glove controlled by user button was evaluated in thirteen participants tetraplegia. Performance outcomes included using Jebsen Taylor Hand Function Test,...
This paper presents a fully-integrated soft robotic glove with multi-articular textile actuators, custom sensors, and an intuitive state machine intent detection controller. We demonstrate that the pressurized actuators can generate motion force comparable to natural human fingers through bench-top testing. apply textile-elastomer capacitive sensors track finger flexion via strain detect contact objects force. Intuitive user control is achieved controller based on signals from integrated...
Abstract Chronic impairment in the paretic ankle following stroke often requires that individuals use compensatory patterns such as asymmetric propulsion to achieve effective walking speeds needed for community engagement. Ankle exosuit assistance can provide biomechanical benefit lab, but environments inherently limit amount of practice available. Community studies without exosuits massed and speed are limited their ability assist proper mechanics. In this study, we combined positive...
The knee joint experiences significant torques in the frontal plane to keep body upright during walking. Excessive loading over time can lead osteoarthritis (OA), progression of which is correlated with external adduction moment (KAM). In this paper, we present a wearable soft robotic exosuit that applies hip abduction torque and evaluate its ability reduce KAM. uses portable cable actuation system generate when desired while remaining unrestrictive unpowered. We explored five different...
In this paper, we present the design, characterization and preliminary testing of a soft inflatable wearable device that can apply assistance in parallel with wearer's abductor muscles. The is composed three-piece textile suit integrated textile-based hip abduction actuator (HAA) produce an assistive torque about frontal plane when pressurized. We characterize output at multiple obliquity angles pressures using instrumented mannequin, show achieves maximum ~14 Nm 345 kPa. A proof concept,...
Abstract Background During inpatient rehabilitation, physical therapists (PTs) often need to manually advance patients’ limbs, adding burden PTs and impacting gait retraining quality. Different electromechanical devices alleviate this by assisting a patient’s limb advancement supporting their body weight. However, they are less ideal for neuromuscular engagement when patients no longer weight support but continue require assistance with as recover. The objective of study was determine the...
