Combined augmented reality and electrical stimulation to improve hand and arm function after cervical spinal cord injury
Official title: Assessing the Feasibility and Safety of a Combined Closed Loop Functional Electrical Stimulation and Augmented Reality System for Individuals With Cervical Spinal Cord Injury
Run by University Health Network, Toronto · NCT07299734 · Data updated 2026-11-12
This project will test whether a combined augmented reality (AR) and functional electrical stimulation (FES) system can help people with chronic cervical spinal cord injury improve their upper-limb grasping and everyday hand use over 20 one-hour sessions.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with chronic cervical spinal cord injury who can perform some object manipulations but show visible impairment (GRASSP prehension score 5–25), have muscles that respond to FES, no FES contraindications, and can follow study procedures.
✕Probably not a fit
People whose muscles do not respond to FES, who have contraindications to electrical stimulation (e.g., pacemaker, implanted neurostimulator, uncontrolled seizures), or who cannot attend the in-person sessions are unlikely to benefit from this intervention.

What this trial studies
This early-phase pilot uses a combined AR+FES device to deliver upper-limb rehabilitation across 20 one-hour sessions delivered over 10 weeks, during which participants interact with virtual and real objects while targeted muscles are stimulated. The primary goals are to demonstrate safety by monitoring for serious adverse events and to show feasibility by confirming participants can set up and use the system independently. Secondary outcomes include adherence to the session schedule and structured user feedback on usability and experience. The study enrolls people with chronic cervical spinal cord injury who retain some ability to manipulate objects but have measurable impairment and is conducted at the Lyndhurst Centre, Toronto Rehabilitation Institute - University Health Network.
Why it matters
Potential benefit: If successful, the system could improve hand and arm function and increase independence with everyday tasks for people with cervical spinal cord injury.
How similar studies have gone: Non-invasive FES has shown benefit for upper-limb recovery in prior studies, but combining FES with augmented reality is a novel approach that remains largely untested in cervical SCI.

Inclusion Criteria: * Chronic cervical SCI * Any level or severity of cervical SCI, traumatic or non-traumatic * Can carry out object manipulations but with visible impairment (i.e., 5-25 on the GRASSP Prehension Performance sub-score). Exclusion Criteria: * Any disease or injury other than the SCI that may be affecting grasping performance. * Individuals with any self-reported FES contraindications (pacemakers, implantable defibrillator, implanted neurostimulation device, metallic implants in the stimulated areas, cardiac conditions, epilepsy, uncontrolled seizures, wounds or fractures on the target limb) * Inability to understand the study procedures * Muscles do not respond to FES to produce grasping movements * Currently participating in another upper limb rehabilitation intervention study (regular physical and occupational therapy is permitted).
