Multiple sclerosis (MS) is a disease affecting the white matter of the central nervous system. In France, it concerns approximately 80 000 patients and represents one of the most frequent neurological affections in young adults. Effort deconditioning of people affected by MS is already proven, but it is not just linked to the disease itself. The decrease of capacities to produce an effort is aggravated by neurovegetative and cardiovascular disorders. The limitation or the complete stop of physical activity is often linked to the fear of a handicap aggravation. Causes of stop are multiple, including fatigue and balance disorders, even if the handicap level is low (average EDSS = 2). Walking disorders generated by MS are frequent, represent the first symptom of the disease (10 to 20 % of cases) and alter significantly the quality of life.
Some reeducation programs were proposed in hospitalization with some efficiency on functional capacities. It is now admitted that physical exercise is not noxious, and allows the implementation of effort reeducation for MS. Randomized controlled studies have shown in MS patients an improvement of physical abilities, of O2max (aerobic capacity), of quality of life and a decrease of fatigue. For MS, only a few studies estimate the effect of effort reeducation on treadmill. Unfortunately, the efficiency of these programs on walking endurance are controversial.
During the maximal cardiorespiratory effort test, the ventilatory threshold 1 (VT1) corresponds to a greater increasing of CO2 compared to O2. The identification of VT1 allows the precise determination of the limit from which the body is incapable of producing the necessary energy to realize an effort using the aerobic metabolism. The VT1 is situated at a level of load with enough intensity for the subject to support the test without dyspnea. A VT1 lower than 40 % of the theoretical VO2 max is considered as a marker of maladjustment to effort due to dyspnea and excessive muscular fatigue. This indication is very informative about the quality of life of patients.
The goal of this study is to apply a personalized reeducation concerning the working load pre-hyperventilation to deconditioned subjects, easily worried by effort induced breathlessness and fatigue in order to get the optimization of the aerobic function. The hypothesis is that reeducation at this level improves the distance of walking and the quality of life of patients affected by MS.
