The cluster controlled trial is conducted over a six months period after recruitment of residents from 4 different nursing homes in France. The participants are distributed into 3 groups. One group does not receive incentive from carers to visit any garden, the second group receives incentives to visit regularly a conventional sensory garden and the third group receive incentives from carers to visit regularly an enriched garden. The study is conducted over a period of 6 months. All participants are giving consent to the study. They will be evaluated before and after over 4 different tests. MMSE (Mini Mental Status Examination) for cognitive impairment, ADL (Activity for day Living) for functional autonomy, TUG (Test up and Go) and Unipodal Stance for prevention of falls.
