| Hand Grip Dynamometer (kg) |
Average of maximum force produced across three trials. |
| Finger Tapping (taps) |
Average of number of taps achieved across five 10-second trials. Measures distal motor speed and lateralized coordination. |
| JTHFT (s) |
Total time to complete battery of simple tests: writing, page turning, lifting small objects, simulated feeding, stacking checkers, lifting light objects, and lifting heavy objects. Measures daily function of upper extremities. |
| Grooved Pegboard (s) |
Time to fill a board of 25 holes with keys. Measured upper extremity motor function. |
| Vmax in 2D (m·s-1) |
Maximum velocity achieved during path movement from start to target with air sleds (2 Dimensions). |
| Final Potion Error in 2D (cm) |
Distance between final cursor position and target with air sleds (2 Dimensions). |
| Linearity Deviation in 2D |
Ratio of cumulative hand path length to the straight-line distance between the starting point and target with air sleds (2 Dimensions). |
| Vmax in 3D (m·s-1) |
Maximum velocity achieved during path movement from start to finish without air sleds (3 Dimensions). |
| Final Position Error in 3D (cm) |
Distance between final cursor position and target without air sleds (3 Dimensions). |
| Linearity Deviation in 3D |
Ratio of cumulative hand path length to the straight-line distance between the starting point and target without air sleds (3 Dimensions). |
