# Leads With Wrist

> Binary indicator if wrist leads the swing: if wrist initiation event occurs before pelvis initiation event. This identifies improper swing sequencing where the upper body initiates before the lower body.

## Technical Details

* **Variable Type:** Discrete Metric
* **Data Type:** Boolean
* **Units:** True/False
* **Column Name:** `leads_with_wrist`
* **Aggregation:** rate
* **Precision:** 0
* **Optimal Direction:** Lower is better
* **Unknown Value:** -1
* **Calculation:** Wrist initiation event \< Pelvis initiation event (launch)
* **Optimal Value:** False (pelvis should initiate first)

## Description

This flag indicates whether the wrist initiation occurs before pelvis initiation, which represents improper swing sequencing. In an optimal swing, the pelvis should initiate before the wrists.

## Use Cases

* Swing sequencing analysis
* Technique correction
* Upper body timing assessment
* Kinetic chain evaluation
