How Your Suboccipital Muscles May Be Prolonging Post-Concussion Syndrome Most doctors treating post-concussion syndrome focus exclusively on the brain. The problem is they're missing a critical piece of the puzzle that sits right at the base of your skull. Your suboccipital muscles—four tiny muscles where your head meets your neck—play a far larger role in post-concussion syndrome than most people realize. Recent research shows these muscles aren't just innocent bystanders after a head injury. They're active contributors to persistent symptoms that can last months or years. What Are the Suboccipital Muscles? The suboccipital muscles are four small but mighty muscles located at the junction between your skull and the top of your neck. Think of them as the fine-tuning system for your head position and movement. These muscles include: Rectus capitis posterior major - The largest of the four, running from the second cervical vertebra (C2) to the base of your skull Rectus capitis posterior minor - The smallest but most important for post-concussion symptoms Obliquus capitis superior - Connects the first cervical vertebra (C1) to your skull Obliquus capitis inferior - Links C1 and C2 vertebrae What makes these muscles special isn't their size—it's their incredible sensory capacity. The suboccipitals are so important for proprioceptive information that one study found that the inferior oblique and RMAJ had 242 and 98 spindles per gram of muscle tissue, compared to the traps and lats which had 2.2 and 1.4 muscle spindles per gram. The Myodural Bridge: A Direct Connection to Your Brain Most muscles in your body attach to bone. The suboccipital muscles are different. The rectus capitis posterior minor has a unique connective tissue bridge to the dura mater, which has been noted on both anatomic specimens and MR imaging. This connective tissue bridge is responsible for resisting dural enfolding during neck extension. This connection, called the myodural bridge, creates a direct mechanical link between these neck muscles and the protective covering of your spinal cord and brain. When trauma affects these muscles, it can directly impact the dura mater—the tough membrane that surrounds your central nervous system. How Concussion Trauma Affects Your Suboccipital Muscles When you sustain a concussion, the same forces that injure your brain also traumatize your neck. All concussion injuries will have a component of a whiplash injury. The cervical spine is supported by over 20 muscles, spanning from the base of your skull to your last cervical vertebrae and extending to other areas such as your upper back, shoulders, and skull. After a concussion or whiplash injury, these intricate neck structures are typically disrupted, resulting in inhibited muscle function and increased tension. This disruption can confuse signals sent to the brain, leading to various related concussion/ whiplash symptoms. The research backs this up. When there is significant trauma to the neck, studies have shown that the cross-sectional area (CSA) of the suboccipitals decreases (atrophy). Research has also shown that there is a correlation between the decreased CSA of RMAJ and RMIN in individuals with chronic tension-type headache. The Research: Smaller Muscles, Bigger Problems A groundbreaking study published in the American Journal of Neuroradiology examined the connection between suboccipital muscle size and post-concussion symptoms in 64 patients. In mild traumatic brain injury, the rectus capitis posterior minor is the only suboccipital muscle whose cross-sectional area is associated with symptom severity and worse outcome. Given the unique connection of this muscle to the dura, this finding may suggest that pathology of the myodural bridge contributes to symptomatology and prognosis in mild traumatic brain injury. The study found that patients with smaller rectus capitis posterior minor muscles experienced: More severe symptoms overall Longer recovery times Worse performance on verbal memory tests Higher rates of persistent headaches A recent article published in the American Journal Neuroradiology looked at the CSA of the RMIN in individuals with post concussive symptoms. The researchers found that a smaller CSA was associated with increased symptom severity, longer recovery time, poor verbal memory performance and increased prevalence of headaches. Why This Matters for Your Recovery The connection between these tiny muscles and your persistent symptoms isn't just academic—it's actionable. The reason for this is following an injury to the neck, the suboccipitals alter their function, and lose some of their sensory information and endurance strength capabilities. This affects their ability to anchor the spinal dura during head and neck movements, causing the dura to buckle with neck extension. A reduction of sensory information also alters the gate control of pain. When your suboccipital muscles can't do their job properly, several problems cascade: Altered Proprioception: Your brain loses accurate information about head position, contributing to dizziness and balance problems. Dural Tension: The protective covering around your spinal cord can't maintain proper tension, potentially affecting cerebrospinal fluid flow. Pain Amplification: Disrupted sensory input changes how your nervous system processes pain signals. Postural Dysfunction: Your head-forward posture puts additional strain on these already compromised muscles. Exercise Solutions for Suboccipital Muscle Recovery The good news is that targeted exercises can help restore function to these critical muscles. Research shows that specific training approaches can make a significant difference in recovery. Deep Cervical Flexor Strengthening Deep cervical flexor muscle (DCF) activation is impaired with neck pain. This study investigated the effects of low load cranio-cervical flexion (C-CF) and neck flexor strengthening exercises on spatial and temporal characteristics of DCF activation. The Chin Tuck Exercise Start with the foundational movement that retrains proper muscle activation: Lie on your back with knees bent, feet flat on the floor Place a small towel under your head if needed for comfort Gently tuck your chin toward your neck, creating a "double chin" Focus on feeling the back of your head slide against the surface Hold for 5-10 seconds, then slowly release Repeat 10-15 times, 2-3 times daily Focus on the deep neck flexors and try to keep superficial muscles as relaxed as possible. Progress to performing from a flat surface or including holds. Progressive Head Lift Once you've mastered the basic chin tuck: Start in the same position as the chin tuck Perform the chin tuck and hold it Slowly lift your head 1-2 inches off the surface while maintaining the chin tuck Hold for 5-20 seconds (start shorter and build up) Lower your head slowly while maintaining the chin tuck Rest briefly between repetitions Beginning with 3 sets of 20-second holds, with rest periods involving placing the head on the floor, can be an excellent starting point for effectively training neck strength post-concussion or whiplash injury. Suboccipital Stretch and Release Techniques Manual Suboccipital Release Using the PIP joint—these joints here—and the flat surface here to work it out. So what you're going to do is, whatever side you want to work—so say if I want to work the right—I'm going to look to the left. I'm going to start where the skull comes right back in, and what I'm going to do is down and out. Locate the base of your skull where it meets your neck Use your knuckles or fingertips to apply gentle pressure Look away from the side you're working (if working the right side, look left) Apply sustained pressure for 30-60 seconds Perform small chin tuck movements while maintaining pressure Switch sides and repeat Suboccipital Stretch Place your right hand on your chin and apply pressure down and back. With your top hand, pull up and over. Hold for 3 deep breaths and repeat 3 times. Cervical Range of Motion and Strengthening Gentle Neck Movements Gently turn your head from one side to the other. Move your eyes in the same direction, progressively aim to see the wall in line with your shoulder. This activity is similar to the activity you did lying down, only this time you do it sitting. Repeat 10 times. Start with these gentle movements: Head Turns: Slowly turn your head left and right, moving your eyes in the same direction Side Bends: Gently tilt your head toward each shoulder Forward and Backward: Slowly nod your head forward (leading with chin) and look up toward the ceiling Isometric Strengthening Press your palms against the back of your head while pushing your head backward using your neck muscles. Hold. Relax. Repeat. Perform isometric exercises in all directions: Forward resistance (hands on forehead) Backward resistance (hands on back of head) Side resistance (hand on side of head) Hold each position for 5-10 seconds, repeat 5-10 times. Advanced Strengthening with Equipment Using a pressure biofeedback unit (PBU) is a more effective method for DCF strengthening than conventional exercises. However, until now, there has been little information regarding the ability of subjects to maintain the benefits of DCF training. For those ready for more advanced training, consider: Resistance Band Training: Use light resistance bands to add progressive load to neck movements. Pressure Biofeedback: If available, pressure biofeedback units can help ensure proper muscle activation during exercises. Important Safety Considerations When you are doing the exercises, stop and contact your doctor or therapist if you notice: dizziness, light headedness, blurred vision, fainting or disorientation, sudden pain shooting down your arm, or numbness or weakness in your arm or hand. Always stop exercising and consult your healthcare provider if you experience: Increased dizziness or lightheadedness Sharp shooting pain down your arms Numbness or tingling in your hands or arms Severe headache that worsens with exercise Visual disturbances The Bigger Picture: Why Neck Treatment Matters in Concussion Recovery Post-concussion syndrome isn't just a brain problem—it's a brain and neck problem. The suboccipital muscles represent a crucial link between these two systems. When these muscles are functioning properly, they provide accurate sensory information to your brain and help maintain proper positioning of critical structures. Differentiating between physiologic, cervicogenic and vestibulo-ocular PCS is vital, as the management of each differs considerably. Based on the current evidence, and depending on the type of PCS, the following interventions may be useful in promoting efficient neurologic recovery and/or resolution of associated musculoskeletal impairments: light asymptomatic aerobic activity (as early as 48 hours) followed by graded subsymptomatic exercise, upper cervical spinal manipulation/mobilization, dry needling to the suboccipital muscles, exercises that target the deep neck flexors along with gaze stability, neck proprioception, vestibulo-ocular and general balance training.
