Feasibility and Safety of a Combined Augmented Reality and Functional Electrical Stimulation System

About this trial

This pilot study is enrolling 7 participants with chronic cervical spinal cord injury to test the effect of a combined augmented reality (AR) and functional electrical stimulation (FES) system on upper-limb function. AR is a computer generated experience of visual displays that simulate the real world, through head-mounted displays such as smart-glasses. FES is a technique that applies electrical stimulation through the skin to nerves to cause contraction of weakened or paralyzed muscles. The combined AR + FES system is a non-invasive device that integrates an AR headset with surface electrodes to deliver stimulation regulated by tracked hand posture and task targets. If included, participants will complete 20 one-hour AR + FES rehabilitation sessions over 10 weeks, interacting with various objects (e.g., block, credit card, marble) during upper-limb training. Final assessment of safety and feasibility will be performed after 14 weeks.
