Middle Scalene (Scalen L)
The M. Scalenus Medius (Middle Scalene) is a muscle of the head & neck region. It is responsible for lateral flexion of cervical spine, elevation of 1st rib (accessory respiratory muscle). This muscle is not covered by the official SENIAM catalogue — placement is based on established clinical literature. This page documents the exact electrode position, anatomical attachments and a standardized test movement based on Hermens et al. (2000).

Lateral flexion of cervical spine against resistance with fixed thorax
This muscle has no SENIAM-standardized electrode position. Placement should be based on anatomical knowledge.
The electrode is placed — what next? easyEMG visualises muscle activity in real time, with SENIAM-compliant placement guidance, up to 4 channels at once and biofeedback training right afterwards.
In therapy, this muscle is usually about tone regulation and consciously relaxing below a threshold.
