Functional Electrical Stimulation for Individuals With Secondary Progressive Multiple Sclerosis
Secondary progressive multiple sclerosis (SPMS) is a subtype of multiple sclerosis (MS) for which there are no existing therapies that alter the disease course. This research will utilize cutting edge functional electrical stimulation (FES) cycling technology with the goal of improving walking in individuals with SPMS. The investigators hypothesize that FES cycling will improve walking in subjects with SPMS.

Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Evaluating the Effects of Functional Electrical Stimulation on Ambulation in Individuals With Secondary Progressive Multiple Sclerosis|
- Change in timed 25 foot walk from baseline to end of training [ Time Frame: Participants are assessed at baseline (visit 1), one-month (visit 2), two-months (visit 3), three-months (visit 4), end of study (visit 5) ] [ Designated as safety issue: No ]Here we will assess whether a subjects walking speed is improved following active cycling with functional electrical stimulation. Our prediction is that individuals will improve in their walking function following seated active cycling with functional electrical stimulation.

|Estimated Primary Completion Date:||June 2014 (Final data collection date for primary outcome measure)|
Active Comparator: functional electrical stimulation
Individuals will receive active functional electrical stimulation while on the stationary bike, or their legs will be passively moved while on the stationary bike during the exercise sessions.
Behavioral: exercise training
The exercise program uses a stationary bike equipped with functional electrical stimulation of leg muscles. The training program is expected to be performed for one hour, three times a week for 12 weeks.
Individuals with secondary progressive multiple sclerosis (SPMS) experience significant impairments in ambulation leading to use of canes, walkers, and ultimately wheelchairs. Treatment attempts for progressive MS have been disappointing. No therapeutic intervention has been shown to modulate disability in patients with SPMS. FES cycling has been shown to have multiple primary medical benefits including: increased muscle mass, improvements in bone density, enhanced cardiovascular function, improved bowel function, decreased spasticity and reductions in bladder infection rate. More importantly FES may modulate the inflammatory CNS environment in progressive MS. The investigators are proposing a novel, and easy to implement intervention strategy of FES cycling to help improve gait function in individuals with SPMS. A successful outcome on a larger SPMS population would have significant impact towards changing MS clinical care. FES is easily transferable to clinical practice and could potentially ameliorate other complications associated with SPMS such as spasticity, mood and fatigue reducing the burden of health care cost. In addition, the investigators will gain a better understanding of the mechanisms underlying these changes that could be used to design new therapeutic strategies.
