Motion type | Graphical representation | Description |
|---|---|---|
Cross |
| With the elbow joint in maximum extension, the hand describes two arcs generated by thoraco-humeral rotations consisting in two successive elevation movements (ROM equals to Ɵ; plane of elevation = 0°: abduction, 90°: forward flexion) |

| With the elbow joint in maximum extension, the hand describes four arcs generated by thoraco-humeral rotations consisting in four successive elevation movements (ROM equals to Ɵ; plane of elevation = 0°: abduction, 30°, 60°, 90°: forward flexion) |
