Contribution of the Evaluation of Body Composition by Connected Scale in the Effectiveness of a Reconditioning Program Through Physical Activity Adapted for Patients Suffering From Chronic Diseases

The goal of this interventional study is to evaluate the impact of the use of a connected impedance scale on the physical and mental quality of life of patients suffering from chronic diseases and participating in a physical activity rehabilitation program. The main objective is to know if a regular monitoring of the evolution of body composition parameters recorded by the connected scale would allow patients participating in the Physical Activity rehabilitation program at Hôtel-Dieu to follow in real time the effects of such program, not on weight itself but on body composition, and that this would contribute to a better perception of physical and mental quality of life at the end of the program 90 Participants will be randomized in two groups : * Control group (N = 45) : routine care * Interventionnal group (N=45) : routine care + use of connected scale All participants will undergo physical activity rehabilitation program during 6 weeks. Patients will be see again at 6 months, and the following parameters will be comparer between the two groups : * SF-36 questionnaire * Ricci \& Gagnon questionnaire * 6MWT * 30 sec sit-to stand test * Ito-Shirado test * Sorensen test * Handgrip test * MaxV02
