Improving Grasp Function After Spinal Cord Injury With a Soft Robotic Glove

Area of Science:

• Rehabilitation Engineering
• Assistive Technology
• Biomedical Devices

Background:

• Tetraplegia from spinal cord injury causes severe hand impairments, leading to dependence.
• Wearable robotic devices offer potential to restore hand function for daily activities.

Purpose of the Study:

• To evaluate the performance of a textile-based soft robotic glove in individuals with tetraplegia.
• To assess the glove's impact on activities of daily living, hand function, and grasp strength.

Main Methods:

• Thirteen participants with tetraplegia tested a user-controlled, button-activated soft robotic glove.
• Performance was measured using the Jebsen Taylor Hand Function Test, active range of motion, and grasp strength.
• Comparison between baseline (no glove) and assisted performance was conducted.

Main Results:

• Participants completed 50% more daily living tasks with the glove (Jebsen Test).
• Significant improvements observed in power and pinch grasp forces.
• Active range of motion of fingers also showed significant improvement.
• Greater benefits were noted for participants with lower baseline motor function.

Conclusions:

• The user-controlled textile-based soft robotic glove effectively improves daily living abilities in individuals with tetraplegia.
• This technology demonstrates significant potential for enhancing hand function and independence after spinal cord injury.
