ASSESSMENTS The primary outcome measure will be the Action Research Arm Test (Lyle 1981. See diagram 12 under 'Appendix'), which has been used in similar studies (Schneider; 2007, Altenmueller; 2009, Grau-Sanchez; 2013) thus enabling some comparison of data with this study. It is a 19 item measure that is divided into four categories: grasp, grip, pinch and gross movement. Each item, or action, is performed by the participant while seated a measured distance from a table (15cm), where all of the assessment items are placed (blocks of wood of various sizes, smaller items, etc). The test recreates the movements or sequences of movements common to activities of daily living, such as reaching up onto a shelf to pick up a can of soup. A table map for the ARAT is laid out flat on the table top and this has markers on it to indicate the start and end position for each object used in the test, thus optimising consistency between patients and setting.
