Summary

Cervical spinal cord injury (cSCI) can result in substantial loss of upper-limb function, with associated socio-economic impact on affected individuals and the healthcare system. Evidence suggests that non-invasive neuromodulation such as functional electrical stimulation (FES) therapy can contribute to regaining upper-limb function, which is a top priority for this population. This pilot study will involve individuals with cSCI using a device that combines augmented reality (AR) and functional electrical stimulation (FES) for 20, one-hour sessions over a 10-week period. The sessions will include upper-limb rehabilitation where individuals will interact with different objects with the aid of the AR +FES system. The primary objective is to assess safety and feasibility, measured by the absence of serious adverse events and participants' ability to independently set up and use the system. Secondary objectives include adherence to the intervention and user feedback through structured interviews. Exploratory outcomes will examine preliminary efficacy using clinical measures such as the Spinal Cord Independence Measure (SCIM) and the Graded Redefined Assessment of Strength, Sensation and Prehension (GRASSP).

Conditions

  • Cervical Spinal Cord Injury

Interventions

DEVICE

AR + FES

Within each one-hour experimental session, participants will interact with different objects (e.g. block, credit card, marble). They will be wearing an augmented reality (AR) headset and electrodes will be placed over finger flexors, thumb flexors and finger extensors muscles. The AR headset will track hand posture and use the difference between the actual posture and a target posture to regulate functional electrical stimulation (FES) delivered via the electrodes.
