Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The global aim of this study is to contribute evidence for the role of targeted exercise in altering MS outcomes over time. The design is a randomized controlled trial (RCT). The primary research question is to what extent does an MS Tailored Exercise Program (MSTEP) result in greater improvements in exercise capacity and related outcomes in comparison to a program based on general guidelines for exercise among people with MS who are sedentary and wish to engage in exercise as part of MS self-management. The primary outcome for this question is exercise capacity measured using cycle ergometry. However exercise efficiency, functional ambulation, strength, components of quality of life including frequency and intensity of fatigue symptoms, mood, global physical function, health perception, and illness intrusiveness, will also be measured as components of a global response outcome. The first confirmatory hypothesis is that MSTEP will result in a greater proportion of people making clinically relevant gains (at least 10% change) in exercise capacity than with general guidelines after 12 months of intervention; a secondary hypothesis is that, while there may be some decline in exercise capacity among individuals from end of intervention to follow-up one year later, the decline will be greater in the general guideline group augmenting the difference between groups in the proportion making 10% change from study entry to 24 months. In other words, gains will be maintained more for the MSTEP group over the general guideline group.
An exploratory hypothesis is that more of the targeted outcomes will improve with the MSTEP program than the general guideline approach. An explanatory hypothesis is that these gains will be accompanied by reports of greater exercise enjoyment and exercise self-efficacy (confidence) with the MSTEP program than with the general guideline program leading to more consistent exercise engagement and improved long-term adherence.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The investigators are targeting a sample size of 120 per group (total 240), which would be sufficient to detect RR of \> 1.5 with 80% power. Sample size estimated using pc-size software. The sample size takes into account that drop-outs will inflate the variance of outcomes as multiple imputation will be used to deal with missing data.
The main analysis will be logistic regression to test the main hypothesis related to the superiority of the MSTEP program based on a greater proportion of people making a clinically relevant gain in exercise capacity at 1 year. A secondary outcome will be the differences in proportions at 2 years also using logistic regression. The analysis will be based on intention-to-treat and all persons will be analysed in the groups to which they were randomized.
A secondary analysis will estimate the impact of exercise on the other relevant outcomes. For this approach, each outcome will be converted to a binary response variable based on published clinically meaningful changes and generalized estimating equations (GEE) will be used to test the rate of response in the MSTEP program to the rate of response in the general guideline approach. Multiple outcomes improves the efficiency of the study as the total number of data points is equivalent to the total n multiplied by the number of tests and reduced by the extent to which the outcomes are correlated. Highly correlated outcomes will make the effective sample size smaller than less strongly correlated outcomes. If there is a statistically significant effect of the intervention, then and only then, can the effects of the separate outcomes be interpreted as real.
The results of the trial will be used to develop guidelines for exercise for MS. The investigators are in the process of copyrighting the name of the program (MSTEP). Upon publication of the findings, the description of content will be made available at no cost. If proven effective, a training guide for professionals and patients will be produced most likely taking advantage of the end-of-grant Knowledge Translation (KT) Supplement. Note: The investigators have been funded by the KT supplement to produce a general guide for people with MS, entitled: Getting on with Your Life with MS. The knowledge generated can be used by people with MS and health professional to promote exercise engagement.

Study Groups

MSTEP
The MSTEP program is a 6 day tailored exercise program. It includes flexibility, aerobic, peripheral strengthening, core and balance training, power and speed training and push days.
MStep
Participant will meet with instructor twice to learn how to exercise safely. Exercises will be demonstrated and practiced under the direct supervision of the instructor. Written details and pictures will be made. Variety in exercise will be encouraged to promote long-term adherence. Stretching, strengthening and relaxation exercises will be given. Persons will be given Thera Band® to facilitate resistance exercise training and instructed how to progress. Equipment such as Nordic Walking Poles, stationary bicycle, BOSU®, or exercise balls will be available. Rather than having a fixed rigid prescription, the aim is to get people to intuitively adjust the amount of resistance so they feel they are working without causing harm, they are not doing the same boring activity, week in week out.
General guideline approach
The general Guideline approach is the general guidelines that are recommended for people with MS by the Canadian Society Exercise Physiology.
General guideline approach
Individuals in the control condition will meet with the exercise instructor on two occasions during the first two weeks to review key components of public health guidelines for physical activity and health. In brief, the general guidelines for MS are (i) aerobic and endurance exercise for 30 minutes per session, 3 times per week at an intensity of 60% to 75% of heart rate peak; (ii) weight training for weak muscles, 2 days per week, on non-endurance days, 8 to 15 repetitions per exercise; and (iii) stretching daily with active or passive range of motion exercises, or attendance at Yoga or Tai Chi classes.
