Technical Details
- Variable Type: Discrete Metric
- Data Type: Float
- Units: degrees (°)
- Column Name:
contact_phase_trunk_rotation - Measurement: Transverse-plane trunk rotation at Apex (ball contact)
Description
Contact phase trunk rotation measures how far the trunk has rotated (twisted) by the moment of ball contact, relative to its starting orientation. It reflects how much of the trunk’s rotational range has been used by contact, which relates to the Contact Phase Open Trunk Rotation movement flag.Use Cases
- Trunk rotation timing
- Kinetic chain sequencing
- Related to Contact Phase Open Trunk Rotation flag
