After a stroke, 80% of patients continue to have difficulty using their paretic upper limb in activities of daily living (ADL) despite post-stroke rehabilitation practices that aim to promote the use of the paretic upper limb. It is known that functional recovery depends on actual use (Use it or Loose it), but one-time measurements in the clinic do not allow quantification of the actual use of the paretic upper limb in daily life (in the person's living environment).~Project will monitor 30 chronic and 30 healthy subjects over one week period using two wrist worn sensors .~The main objective is to objectively quantify by actimetry, over 7 days, the real functional use of the paretic upper limb in the activities of daily living of post-stroke hemiparetic subjects in chronic phase, by the functional use ratio between the two arms (UseRatio).
