The suboccipital muscle group, located at the base of the skull, is known for its high density of muscle spindles and proprioceptors, which provide crucial sensory input for maintaining posture and balance. Structural and functional changes in these muscles, often due to abnormal head posture, can induce dizziness, vertigo, and other symptoms associated with cervicogenic dizziness. This condition, originating from cervical spine disorders, requires precise assessment and understanding of the intricate relationship between the cervical spine and sensory inputs. While the exact mechanisms are still being explored, the suboccipital muscles' role in cervicogenic dizziness highlights the complex interplay between the musculoskeletal and nervous systems.

Structural and functional changes in suboccipital muscles
Structural and functional changes in the suboccipital muscles can induce dizziness and vertigo. The suboccipital muscles are a group of four muscles located in the posterior region of the neck, inferior to the occipital bone. These muscles are the rectus capitis posterior major, rectus capitis posterior minor, obliquus capitis superior, and obliquus capitis inferior. They serve as postural support of the head and neck and enable neck extension and rotation movements.
The suboccipital muscles have a high density of muscle spindles and proprioceptors, which are sensory receptors that respond to changes in muscle length and provide feedback to the nervous system about body position and movement. Structural and functional changes in these muscles can lead to abnormal proprioceptive inputs to the central nervous system, resulting in inconsistencies with vestibular and visual inputs. This mismatched information integration can manifest as dizziness, vertigo, pain, lightheadedness, and headaches.
Functional or structural changes in the suboccipital muscles have been associated with chronic headaches, chronic neck pain, somatic dysfunction, and loss of standing balance. These changes can be caused by improper or abnormal head posture, leading to unilateral muscle tension and segment instability after fatigue. Additionally, muscle dysfunction caused by repetitive work or strain in the neck region can interfere with muscle responses and contribute to cervical spondylosis.
The relationship between the cervical spine's structural components and the sensory inputs originating from the suboccipital muscles highlights the complexity of the human body's musculoskeletal and nervous systems. Understanding these relationships is crucial for developing effective treatments for conditions affecting the cervical spine and improving activities that require fine motor control and balance.

Abnormal head posture
If the abnormal head posture is caused by refractive errors, it can be corrected by wearing glasses. If the cause is an ocular disease, a simple test can be performed: occluding one eye can prevent diplopia and the compensatory head posture will disappear. In some cases, surgical treatment may be necessary to correct the ocular deviation and abnormal head posture.
If abnormal head posture is caused by non-ocular factors, physical therapy or exercise can help relieve the tightness in the neck muscles. Abnormal head posture can lead to permanently tight neck muscles, causing long-term neck pain or headaches. In children, abnormal head posture may cause abnormal facial bone development, resulting in facial asymmetry. Therefore, early diagnosis and treatment are important to help eliminate abnormal head posture.

Cervical spine disorders
The cervical spine, also known as the neck region of the spinal column, consists of the first seven vertebrae (C1-C7). The cervical spine supports the weight of the head and enables a wide range of head movements, including tilting the head forward and backward, rotating it from side to side, and bending it to one side.
Some common cervical spine disorders include:
- Cervical spondylosis: This is caused by changes to the structures of the backbone and neck due to aging and wear and tear. It can lead to dehydrated discs, herniated discs, bone spurs, and stiff ligaments.
- Cervical herniated disc: The discs between the vertebrae rupture, protrude, or bulge out, sometimes pressing on the spinal cord and nerve roots.
- Degenerative disc disease: The discs between the vertebrae break down, leading to conditions such as degenerative bone and disc disease.
- Cervical spinal stenosis: The spinal canal narrows around the spinal cord, potentially pinching the spinal cord and nerve roots, resulting in tingling, numbness, and weakness.

Musculoskeletal abnormalities
The suboccipital muscle group, located at the base of the skull, is crucial for the body's ability to perform precise movements and maintain posture and balance. Structural and functional changes in the suboccipital muscles can induce dizziness, especially cervicogenic dizziness (CGD). CGD is characterised by dizziness thought to originate from cervical spine disorders and is diagnosed when patients have no underlying problems in the vestibular, cardiovascular or nervous systems.
The suboccipital muscles act as stabilisers and controllers of the head. They have a high density of muscle spindles and proprioceptors, which are sensors that provide feedback to the nervous system about body position, movement, and balance. When the ligaments of the cervical spine are exposed to continued stress, they stretch and deform, causing instability of the spine and subsequent pressure on the base of the spine. This can result in the contraction and spasm of the suboccipital muscles, leading to headaches, migraines, and occipital neuralgia.
Upper cervical spine instability can also cause eye position changes and visual illusory movements, as the proprioceptive information from the neck plays a role in regulating eye position and gaze direction. Cervical instability can dramatically alter balance and give rise to various head, face, and eye symptoms.
In patients with cervicogenic dizziness, tight and dysfunctional upper back and neck muscles can cause dizziness. Aggressive stretching and strengthening of the suboccipital muscles can worsen dizziness, while gentle and gradual stretching can help improve symptoms.

Cervicogenic dizziness treatments
Cervicogenic dizziness is a syndrome of neck pain accompanied by dizziness. It is often confused with vertigo of vestibular origin. It is caused by a sensory mismatch between somatosensory information and input from the eyes and inner ear. Structural and functional changes of the suboccipital muscles can induce dizziness.
There is no single diagnostic test for cervicogenic dizziness, and it can take time for clinicians to rule out other causes of dizziness. Treatment for cervicogenic dizziness is similar to that for neck pain. The majority of patients can be effectively treated with conservative treatment, but a small number of patients who have failed to respond to various non-surgical treatments may require surgery.
Non-surgical treatments for cervicogenic dizziness include:
- Pharmacological treatment: Non-steroidal anti-inflammatory drugs (NSAIDs), antidepressants, muscle relaxants, and Chinese herbal medicines.
- Physical therapy: Stretching exercises, head flexion and rotation exercises, and vestibular rehabilitation exercises.
- Acupuncture: Dry needling.
- Relaxation and meditation: Controlled breathing and the application of heat to the cervical spine.
It is important to consult a specialist for an accurate diagnosis and treatment plan.
