A team of researchers unveiled a promising wearable robotic device designed to help people with cervical spinal cord injuries regain stronger and more functional hand use. The technology, known as MyHand-SCI, focuses on individuals with C6-C7 level injuries, who often retain limited wrist movement but struggle to generate sufficient grip strength for daily tasks.
Many people with these injuries rely on a technique called tenodesis grasp, in which wrist extension passively closes the fingers. While useful, tenodesis produces relatively weak grip force and requires continuous effort, leading to fatigue and discomfort. The MyHand-SCI system addresses these limitations through motorized exotendons that assist finger movement. Users control the device through a novel wrist-angle-based throttle mechanism, allowing them to maintain a grasp without constantly extending the wrist.
The research team tested the device in a pilot case study involving an individual with a C6 spinal cord injury. Results showed measurable improvements in grasp strength and object manipulation. Importantly, the participant could still modulate grip force naturally, enabling more precise handling of everyday items. This combination of assistance and user control is a key feature that distinguishes the device from some earlier assistive technologies.
The study demonstrates how wearable robotics can enhance independence for people living with paralysis. Rather than replacing human movement, the orthosis amplifies residual function, allowing users to perform activities that would otherwise be difficult or impossible. Researchers view the project as an important step toward practical, intuitive assistive technologies that can improve quality of life and reduce dependence on caregivers for routine tasks.
