About

Marfan syndrome (MFS) is a rare genetic disease (1/5000) characterized by the association of ocular impairment, cardiovascular disease and musculoskeletal disease.

In some chronic conditions, physical activity and training have been shown to be effective in improving muscle strength and functional abilities but also fatigue and quality of life. We hypothesize that the implementation of a personalized exercise rehabilitation program (Personalized Training Program) in children and young adults with MFS, by improving muscle mass, physical endurance, muscle strength, bone mass and quality of life of these patients. In order to test this hypothesis, investigators wish to carry out an interventional, prospective, monocentric study for the first time in children and young adults (<25 years old) presenting an MFS.

Full description

Marfan syndrome (MFS) is a rare genetic disease (1/5000) characterized by the association of ocular impairment, cardiovascular disease and musculoskeletal disease. Chronic fatigue and decreased physical endurance are almost constant complaints of patients with MFS (90% according to some studies), and have an impact on activities of daily living and quality of life. The fragility of the connective tissues and the muscle deficit, responsible for increased stress on the musculoskeletal system, may be involved in this symptomatology. This deficiency in muscle mass is already present in young children and worsens in adolescents and young adults, as researchers have shown in a clinical study carried out in the Toulouse MFS competence center. This muscle deficit may also explain, at least in part, the deficit in bone mass observed in children and adults.

In some chronic conditions, physical activity and training have been shown to be effective in improving muscle strength and functional abilities but also fatigue and quality of life. Investigators hypothesize that the implementation of a personalized exercise rehabilitation program (Personalized Training Program) in children and young adults with MFS, by improving muscle mass, physical endurance, muscle strength, bone mass and quality of life of these patients. In order to test this hypothesis, investigators wish to carry out an interventional, prospective, monocentric study for the first time in children and young adults (<25 years old) presenting an MFS.

Rehabilitation Program

Experimental group

Description:

It will consist of 2 sessions of 40 minutes per week, for 12 weeks on ergometric bicycle. Each session of 40 min will include 5 minutes of warm-up, 5 minutes of recovery and 6 sequences of 5 min. Each 5-minute sequence will alternate between 4 minutes of pedaling at a load corresponding to the 1st ventilatory threshold (determined in the initial maximum cardiorespiratory effort test) and 1 minute of pedaling at a load corresponding to 2nd ventilatory threshold (determined in the initial maximum cardiopulmonary stress test).

Treatment:

Device: Rehabilitation program
