Early FES Cycling in Acute Spinal Cord Injury for Neuromuscular Preservation and Neurorecovery

Summary

Spinal cord injury (SCI) is a devastating condition that often leads to paralysis and multiple health problems such as muscle wasting, bone loss and spasticity. Despite the paralysis, functional electrical stimulation (FES) on the skin surface muscles may produce muscle contractions. People who have had an SCI for a long time (chronic SCI) already use FES cycling to exercise, and it is known that it can reverse muscle atrophy and has a wide range of health benefits. Furthermore, animal research suggests that starting exercise training early after new SCI may promote spinal cord recovery. However, not much is known about early FES cycling in humans. Therefore, the investigators propose to study if early FES cycling could prevent muscle wasting, pain or spasticity, and help with spinal cord recovery.

The study will recruit 36 participants with a new, acute SCI, between 14 and 21 days after their injury into 3 groups. An Early-FES group starts FES cycling early after injury (between 14 and 21 days after injury), and for a duration of 6 months. A Delayed-FES group starts FES cycling 3 months after enrolling in the study, and for a duration of 3 months. A Control group does not perform FES cycling.

This pilot study will allow us to study if early FES cycling, in addition to normal care, has greater benefits on the preservation and recovery of the leg muscles and spinal cord function than delayed FES cycling or standard care only. The results of this pilot study may lead to the development of a larger study with early FES cycling after new SCI.

Interventions

DEVICE

Early FES

FES cycling starting 14-21 days post SCI for 6 months, 3 sessions/week, with gradually increasing duration (15-60 minutes), cadence (20-45 RPM) and resistance; surface stimulation of 3-5 muscle groups per leg; with RT300 Supine or SLSA FES cycle (Restorative Therapies, Inc, Baltimore, MD)

DEVICE

Delayed FES

FES cycling starting 3 months (+ 14-21 days) post SCI, for 3 months, 3 sessions/week, with gradually increasing duration (15-60 minutes), cadence (20-45 RPM) and resistance; surface stimulation of 3-5 muscle groups per leg; with RT300 Supine or SLSA FES cycle (Restorative Therapies, Inc, Baltimore, MD)
