Suboccipital Muscles
The Suboccipital Muscles are a group of four small, paired muscles located at the base of the skull (the occipital ridge). They are responsible for the fine-motor movements of the head, specifically rotation and extension at the atlanto-occipital and atlanto-axial joints.
The Muscle Group Includes:
- Rectus Capitis Posterior Major: Extends and rotates the head.
- Rectus Capitis Posterior Minor: Primarily involved in head extension.
- Obliquus Capitis Inferior: The strongest rotator of the head.
- Obliquus Capitis Superior: Extends and laterally flexes the head.
Clinical Significance in Massage Therapy
This muscle group contains a high density of muscle spindles (sensory receptors), making them vital for proprioception. In cases of Forward Head Posture, these muscles become chronically shortened, leading to:
- Suboccipital Neuralgia: Compression of the greater occipital nerve.
- Tension Headaches: Often described as a “tight band” around the forehead.
- Eye Strain: Due to the neurological link between suboccipital tension and ocular movement.
Student Tip: The suboccipitals are deep to the Trapezius and Splenius Capitis. When palpating, use slow, sinking pressure to bypass the superficial layers and reach the “ledge” of the occipital ridge.
