As people are living longer and longer, the consequences on quality of life of the elderly people trend to be social issues.

Indeed, with the aging process (“regular” or “pathological”) elderly people may develop or accumulate some diseases and disabilities that may require physical medicine and rehabilitation intervention.

New technologies are hopeful for the development of innovative tools and services that assist the rehabilitation, particularly at home.

However, even if some new technologies are encouraging, it is important to scope the global consequences of a treatment beyond the improvement of the patient's clinical signs.

Thereby, the quality of life as a complex ensemble, dynamic and integrative, taking into account several domains (physical, mental, social, environmental) tends to be the concept that enables to evaluate more globally the impact of a person's treatment.

Thus, it is necessary to precise the nature and level of assistance to be provided, the level of acceptability and stigmatization of the proposed solution, but also the perceived support and utility.

To do so, the living lab, as a multidisciplinary and controllable domestic environment seems to be an appropriate tool in a process of co-design/evaluation, formation/training and research for innovative products or services encouraging home rehabilitation.

This communication will focus on our approach, our methodology and the living lab as a multifunctional tool (evaluation, training, research) with a feedback of a full year. We will then discuss its limits and its complementarity with an approach in a natural environment, which enables the possibility of longitudinal studies included in the beneficiary's social environment.
