Brief Summary:

The overall objective of this research project is to examine the clinical efficacy of lower extremity cycling with functional electrical stimulation to improve the health and fitness of children with spinal cord injuries (SCI). To achieve this goal, a controlled, randomized study will be conducted with thirty children who have sustained a spinal cord injury. The children in the study will be assigned to one of three groups: those receiving functional electrical stimulation (FES) leg cycling exercise, those receiving passive leg cycling, and a non-cycling control group receiving electrical stimulation therapy to generate muscle contractions in the lower extremity. All three groups will be balanced as to the amount of time they receive the specific therapy. All therapies, after initial assessment, will be conducted at home in order to foster changes in lifestyle that may prove to be essential for improved quality of life.

The specific aims of this proposal are delineated below:

Aim 1: To assess, by means of a randomized controlled study design, the ability of FES cycling to improve the cardiovascular and musculoskeletal systems of ten children with a spinal cord injury, as compared to ten children undergoing passive leg cycling exercise and ten children receiving electrical stimulation therapy alone.

Aim 2: To determine, by means of a randomized controlled study design, the feasibility of using FES leg cycling exercise to provide long-term health benefits and improve the neurologic status of ten children with a spinal cord injury, as compared to ten children undergoing passive leg cycling exercise and ten children receiving electrical stimulation therapy alone.
