The project utilises a pre-experimental one-group pre-test - post-test design. The participants will be assessed at baseline, followed by an intervention and then measured again at follow up.Patients will be purposively recruited from the multiple sclerosis clinic at the Royal Hallamshire Hospital in Sheffield. Potential participants will be identified by consultant neurologists to the research assistant from clinic lists/patient records. Patients who satisfy the inclusion and exclusion criteria will be given/sent a recruitment letter and participant information sheet informing them about the study. The letter will contain a tear-off slip for patients to return to the research team indicating their interest or not in study participation. It will be clearly stated in the letter that there is no obligation or pressure to participate and that if patients are not interested their future medical care will not be jeopardised. Patients who respond to the letter of invitation will be invited into the Centre for Sport and Exercise Science for a consultation.
