Loss of autonomy among elderly during and after hospitalisation is a well-known problem. Patient suffering of sarcopenia (decreasing in muscle mass and function) are more likely not to recover their previous autonomy.

Studies have shown that physical exercise, especially resistance exercises, is the most efficient known treatment of sarcopenia. Several institution-based rehabilitation programs had been implemented in this purpose.

On the other hand, some studies have shown that home-based self-rehabilitation can be as efficient as institution-based rehabilitation, for example in stroke, cardiac failure and COPD rehabilitation.

The investigators propose to set up a home-based self-rehabilitation program to fight against sarcopenia and hence increasing autonomy among elderly. This study aimed to establish the feasibility of such a program.
