The ARAT, developed by Lyle,10 is a standardized
measure of the upper extremity (arm and hand)
function based on four movements: grasping, gripping,
pinching and gross movements of shoulder,
elbow and fingers. ARAT has an ordinal 4-point
scale (0–3) for 19 items. Scoring is determined as
follows: 0, patient cannot perform any part of task;
1, patient is able to lift the object completely from
the platform; 2, function is performed fully but
clumsily or with great difficulty; and 3, the movement
is performed normally. The maximum score
for each arm is 57 points. The test can be completed
in an average of 10 minutes but requires specific
materials
