Trunk Protocol Trial Summary

This trial is testing a new way to help people with spinal cord injuries move their bodies using electrical stimulation.

Who is the study for?
This trial is for English-speaking adults with spinal cord injuries (quadriplegia or paraplegia) between C4-T12, ASIA Scale A-C. They should be stable post-injury (>6 months), without severe bone density issues, orthopedic problems, medical complications, psychological issues, or substance abuse. Participants need normal range of motion and body size and must not be pregnant.Check my eligibility
What is being tested?
The study tests an implanted device called IRS-8 that uses electrical currents to help stabilize the trunk and hips in people with spinal cord injuries. It aims to improve their ability to sit up straight, breathe easier, reach out, push a wheelchair more effectively, and roll over in bed.See study design
What are the potential side effects?
Potential side effects may include discomfort at the implant site, skin irritation from electrodes used during FES therapy sessions. There might also be muscle fatigue due to stimulated contractions.
