Scoring the hand movements item.

Score	Behavioral criterion
6.0	Finger intrinsic against gravity
5.4	Timed thumb opposition
4.8	Finger intrinsic gravity eliminated
4.2	Wrist radial deviation against gravity
3.6	Wrist radial deviation gravity eliminated
3.0	Wrist extension against gravity
2.4	Finger extension against gravity
1.8	Forearm supination
1.2	Any thumb motion
0.6	Finger flexion gravity eliminated
0.0	Unable to perform any motion
