# Global Trunk Rotation at P7 Impact

> Trunk rotation angle relative to its own position at Address, measured in the global reference frame, at P7 Impact.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** deg
* **Column Name:** `global_trunk_rotation_at_p7`
* **Aggregation:** mean
* **Precision:** 0
* **Optimal Direction:** N/A
* **Measurement:** Trunk rotation angle in the global reference frame, sampled at the P7 Impact event

## Description

Global Trunk Rotation at P7 Impact reports the trunk rotation angle relative to its own position at Address, measured in the global reference frame, sampled at the P7 Impact event. Global angles are expressed relative to the ground/vertical reference frame rather than a body-relative axis, making them comparable across different camera setups.

## Use Cases

* Global posture assessment
* P7 Impact position analysis
