Kinematic parameter | Definition |
|---|---|
General kinematics | |
Movement onset (MO; seconds) | Time at which wrist speed exceeded 50 mm/s |
Object contact (seconds) | When object movement ≥ 1 mm from original position |
Reach dynamics | |
Time to object contact (TTC; seconds) | Time between movement onset and object displacement ≥ 1 mm |
Path deviation ratio | Deviation of the movement trajectory from a straight route between the starting and object contact wrist positions |
