At the first visit to the Clinical research Facility, the researcher will check that the patient is still happy to take part. Then, some information about the patient e.g. age, sex, date of stroke, risk factors for stroke will be recorded. Next, the therapist will assess how much existing strength and function the patient has in the arm affected by their stroke using a variety of rating scales. Some brief questionnaires will also be used to measure the patients levels of depression, anxiety, fatigue, quality of life and levels of independence.
