# Electromyography **Domain:** Neurophysiology / Motor Interfaces **Doc Type:** Scientific Concept Node **Maturity:** Established **Related:** [[Neural Interface]], [[DICOM Working Group 32]], [[Multimodal Neural Data]] --- ## Definition **Electromyography (EMG)** records electrical activity associated with skeletal muscle activation. It is not a direct brain recording, but it is often paired with neural data to measure intended or executed movement, evaluate peripheral pathways, and build hybrid control interfaces. ## Architectural role EMG can function as an output correlate, control channel, validation signal, or confound measure. Its synchronization with brain signals is essential when reconstructing sensorimotor intent.
