Abstract
People with tetraplegia resulting from spinal cord injury experience debilitating hand impairments that may lead to lifelong dependence on others to perform activities of daily living. Wearable robotic devices that actively support hand function during daily living tasks could bring great benefits to this population. In this work, the performance of a textile-based soft robotic glove controlled by the user with a button was evaluated in thirteen participants with tetraplegia. Performance outcomes included activities of daily living using the Jebsen Taylor Hand Function Test, active range of motion of the fingers, and grasp strength for power and pinch grasps. In the Jebsen Test, participants showed significant improvements in performance of activities of daily living with glove assistance, completing a median of 50% more tasks than in their baseline attempt without the glove. Significant improvements were also found for power and pinch grasp forces and active range of motion of the fingers with the glove assistance. Participants with lower baseline motor function received greater benefits from glove assistance. This work demonstrates the effectiveness of a user-controlled textile-based soft robotic glove to improve activity of daily living abilities in individuals with hand impairments resulting from spinal cord injury.
