In ankle-foot orthosis development, it is challenging to both specify the appropriate ankle mechanics and design systems that can physically render them. Recently, a new ankle-foot orthosis - the Variable Stiffness Orthosis (VSO) - was intr...
Kinematic compatibility of a wrist robot with cable differential actuation: effects of misalignment compensation via passive joints [0.03%]
通过被动关节补偿错位的缆索差动驱动腕部机器人机构相容性研究

Haider A Chishty et al.
We present the UDiffWrist (UDW), a low-impedance 2-DOF wrist exoskeleton featuring a cable-differential transmission. To investigate the effect of different design strategies for achieving kinematic compatibility, we developed two versions ...
Autonomous Powered Ankle Exoskeleton Improves Foot Clearance and Knee Hyperextension After Stroke: A Case Study [0.03%]
自主式踝部外骨骼可改善卒中患者的足廓清和膝过度伸展:病例研究
Kai Pruyn,Rosemarie Murray,Lukas Gabert et al.
Kai Pruyn et al.
Hemiparetic gait is often characterized by ankle weakness, resulting in decreased propulsion and clearance, as well as knee hyperextension. These gait deviations reduce speed and efficiency while increasing the risk of falls and osteoarthri...
Assessing the utility of Regenerative Peripheral Nerve Interfaces (RPNIs) in providing referred sensations in a functional task in a virtual environment [0.03%]
再生外周神经接口(RPNI)在虚拟环境中的功能性任务中提供牵涉感觉的效用评估

Jake D N Kanetis et al.
Individuals who use upper limb prostheses receive limited feedback from their devices. Researchers have attempted to elicit sensation through direct stimulation of peripheral nerves or through stimulation of reinnervated skin or muscle. Pre...
Grasp Force Assistance via Throttle-based Wrist Angle Control on a Robotic Hand Orthosis for C6-C7 Spinal Cord Injury [0.03%]
通过基于节流的腕关节角度控制在机器人手矫形器上为C6-C7脊髓损伤提供抓力辅助
Joaquin Palacios,Alexandra Deli-Ivanov,Ava Chen et al.
Joaquin Palacios et al.
Individuals with hand paralysis resulting from C6-C7 spinal cord injuries frequently rely on tenodesis for grasping. However, tenodesis generates limited grasping force and demands constant exertion to maintain a grasp, leading to fatigue a...
Human control of underactuated objects: Adaptation to uncertain nonlinear dynamics ensures stability [0.03%]
人类对欠驱动物体的控制:适应不确定的非线性动力学以确保稳定性

This paper introduces a novel magnetic navigation system for cardiac ablation. The system is formed from two key elements: a magnetic ablation catheter consisting of a chain of spherical permanent magnets; and an actuation system comprised ...
Functional resistance training during walking: do biomechanical and neural effects differ based on targeted joints? [0.03%]
行走时的功能阻力训练:针对不同关节的生物力学和神经效应是否有所不同?
