This study will seek to determine the benefits that FES-LE cycling has over cycling alone on walking performance and quality of life in people with multiple sclerosis.
Functional Electrical Stimulation (FES) is a rehabilitation tool that stimulates nerves via electrical current, causing muscles to contract. When FES is appled to leg muscles during stationary cycling the legs move in a fixed rhythmical pattern. Previous studies have demonstrated that FES during cycling is a safe and effective exercise for individuals recovering from spinal cord injury or stroke, but few have applied this tool to a progressive disorder, such as multiple sclerosis (MS). The aim of this study is to assess the immediate and short-term effect of an 8-week training program comparing FES lower extremity cycling to cycling without FES. Twenty volunteers with MS will participate. They will be randomly assigned to a training group. This study examine the effects of training on quality of life, endurance, walking speed, and step quality. Participants will sign an informed consent and complete a questionnaire that includes medical history and demographic data. Before training, immediately after training finishes and one month after training, self-report questionnaires, timed walking tests will be completed. During the walking tests, step quality and speed will be measured with a sensor that is worn on a belt

Gait Velocity: Timed Walking
Gait velocity was reported in meters/second based on a 25 foot walk test called the Timed 25 foot Walk Test. Faster gait speeds are better outcomes.

Self-reported Fatigue Using Modified Fatigue Impact Scale
The Modified Fatigue Impact Scale is a 21 item self-report questionnaire that takes 5-10 minutes to complete. It uses a 5-point likert scale to rate the patient's perception of how Multiple Sclerosis related fatigue affects an individual's life on an everyday basis. It contains three subscales that include: cognitive, physical, and psychosocial dimensions. Scores on the subscales can be analyzed individually or as a summed score to give an overall fatigue score. Higher scores indicate a greater impact of fatigue. The minimum score is a 0 and the maximum score is 81.

Self-reported Walking Using 12 Item Multiple Sclerosis Walking Scale
The Multiple Sclerosis Walking Scale is a 12-item self-report questionnaire that takes approximately 10 minutes to complete and reflects a persons' perception of the impact that multiple sclerosis has on walking ability during the past 2 weeks. Each of the items scored ranges from 1 to 5, in which higher scores indicate a greater impact of multiple sclerosis on their walking. Scores on the 12 items are summed. To transform to a 0-100 scale, the minimum score of 12 is subtracted from the sum; the result is divided by 48 and then multiplied by 100. The lowest score is 0 and the highest score is 100. Higher scores mean a worse outcome.

Overall Self-reported Quality of Life Using Multiple Sclerosis Quality of Life- 54
The Multiple Sclerosis Quality of Life-54 is a self-report quality of life questionnaire. It measures health-related quality of life using both generic and disease-specific measures and was constructed by experts in the field. There is no overall score for this scale since it contains 12 subscales, two summary scores, and two single-item measures. The quality of life subscale was the chosen outcome measure reported below. The scores range from 0-100. Higher scores on the scale notes improved outcome.
