Study Summary

This trial is testing a new, personalized, portable, and non-invasive hand-grasp neuro-orthosis that could help restore naturalistic grasp functions for people with tetraplegia due to spinal cord injury.

Who is the study for?
This trial is for adults over 18 with stable spinal cord injury causing tetraplegia, unable to grasp objects. They must have certain levels of arm and wrist muscle function and be able to attend sessions at home or a site. Excluded are those on ventilators, with specific medical devices, severe spasticity, recent Botox treatments in the arms, or other significant health risks.Check my eligibility
What is being tested?
The study tests a user-controlled FES system designed to restore hand-grasp functions in individuals with tetraplegia from spinal cord injuries. It aims to create personalized neuro-orthoses based on participants' needs and preferences.See study design
What are the potential side effects?
Potential side effects may include discomfort at the electrode sites, skin irritation under the sleeve of the device, muscle fatigue due to electrical stimulation, and possible exacerbation of existing conditions like spasticity.
