Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate a surgically implanted functional electrical stimulation (FES) system to facilitate exercise, standing, stepping and/or balance in people with various degrees of paralysis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Protocol Outline: Patents undergo surgery in which electrodes are implanted into muscles of the trunk and legs. Electrode leads are connected to an stimulator/telemeter. Following implantation, patients undergo training in standing, transfers and other advanced mobility skills using the functional electrical stimulation system. A prescribed course of exercise, functional training and rehabilitation with the implanted stimulation system, followed by laboratory assessments of strength, balance and functional abilities with and without the system, as well as the technical performance of the implanted components. Home-based training follows prior to discharge for home use of the system.

Patients are followed at 6 and 12 months after discharge and then annually thereafter.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Implant

Volunteers are evaluated for appropriateness for inclusion in the study on an intent-to-treat basis. Qualifying candidates all receive the implanted neuroprosthesis and participate in post-operative training and follow-up procedures.

Group Type EXPERIMENTAL

IST (Implanted Stimulator-Telemeter)

Intervention Type DEVICE

Pre-surgical exercise with surface electrical stimulation, surgery including electrode and IST- implanted pulse generator insertion, exercise and physical therapy with the implanted system, functional training and laboratory assessment of clinical and technical performance.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Skeletal maturity and ability to sign informed consent (\>18 years)
2. Non-ventilator dependent paralysis resulting from injuries such as: mid cervical/thoracic (C4 or below) spinal cord injuries, poststroke hemiparesis, TBI, or MS, affecting the trunk and/or lower limbs
3. Innervated and excitable lower extremity and trunk musculature
4. Adequate social support and stability
5. Willingness to comply with follow-up procedures

Exclusion Criteria

1. Non-English speaking
2. Females who are pregnant
3. Current pressure injuries that would be exacerbated by study activities
4. Severe contractures or uncontrolled spasticity of any major joint of the upper or lower extremities that results in a fixed deformity that would interfere with study activities
5. History of spontaneous fractures or other evidence of excessively low bone density
6. History of vestibular dysfunction, balance problems, or spontaneous falls
7. Acute and or/untreated orthopedic problems that would prevent a participant from weight bearing or exercising such as a dislocation or fracture.
