# Global Trunk Tilt at P1 Address

> Trunk side-to-side tilt angle relative to the global reference frame, at P1 Address.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Float
* **Units:** deg
* **Column Name:** `global_trunk_tilt_at_p1`
* **Aggregation:** mean
* **Precision:** 0
* **Optimal Direction:** N/A
* **Measurement:** Trunk tilt angle in the global reference frame, sampled at the P1 Address event

## Description

Global Trunk Tilt at P1 Address reports the trunk side-to-side tilt angle relative to the global reference frame, sampled at the P1 Address 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
* P1 Address position analysis
