====== Normalize EMG Signal to Maximum Within Gait Cycle ======

===== Integrate EMG =====

=== Integrating an EMG envelope between events ===

The result of integrating a signal is a single metric value per event range. For example, the commands below will integrate an EMG signal between events from **Start** to **End**
