What Happens to Your Body After a Concussion?

A concussion is more than a headache or a few days of brain fog. It disrupts how your brain processes sensory information and coordinates movement. This is called sensorimotor disruption, and it affects the connection between your vestibular system (balance), your visual system, your cervical spine (neck proprioception), and your motor control.

Many people in Fredericton who experience a concussion after a car accident, sports injury, or fall notice symptoms like poor balance, unsteadiness, difficulty concentrating while walking, and a general feeling of being “off.” These symptoms often persist well beyond the initial injury and are not always resolved by rest alone.

At Fredericton Family Chiropractic, we focus on active, evidence-based rehabilitation that targets the specific systems affected by your concussion, with a particular emphasis on cervical mobilization and guided at-home exercises.

Why the Neck Matters After a Concussion

Your cervical spine plays a critical role in balance, spatial awareness, and coordinated movement. The upper neck contains a dense network of proprioceptors, which are sensory receptors that tell your brain where your body is in space. When a concussion occurs, the neck is almost always affected too, especially in cases involving whiplash.

Research shows that cervical proprioceptive dysfunction contributes significantly to post-concussion symptoms like dizziness, unsteadiness, and visual disturbance. The neck is not separate from the concussion picture. It is a key contributor to sensorimotor control and should be assessed and treated as part of a comprehensive recovery plan.

Mobilization vs. Adjustment: What’s the Difference?

When most people think of chiropractic care, they picture a traditional spinal adjustment, which involves a quick, targeted thrust to a joint. While adjustments are a valuable tool in many situations, concussion recovery often calls for a different approach: mobilization.

Mobilization involves slow, controlled, repetitive movements applied to the joints and soft tissues of the cervical spine. It is a gentler technique that works within the joint’s natural range of motion to restore normal movement, reduce stiffness, and improve proprioceptive input to the brain.

For concussion patients, mobilization is often preferred because it:

• Gently restores cervical range of motion without sudden force
• Helps recalibrate proprioceptive signalling from the neck to the brain
• Reduces muscle guarding and tension patterns that develop after injury
• Can be applied gradually as the nervous system recovers

This distinction matters. Concussion recovery is about restoring the brain’s ability to integrate sensory input accurately, and cervical mobilization supports that process by improving the quality of information the neck sends to the brain.

How Sensorimotor Rehabilitation Works

Effective concussion recovery targets the specific systems involved in sensorimotor dysfunction. At our Fredericton clinic, your care plan may include:

Balance and Postural Control Training

Concussion commonly disrupts your ability to maintain balance, especially when visual or surface conditions change. We use progressive balance exercises that start with simple static holds and advance to dynamic, challenging positions. This retrains your brain to accurately process vestibular and proprioceptive input.

Cervical Mobilization and Proprioception Retraining

Through gentle hands-on mobilization of the cervical spine, we work to restore normal joint mechanics and improve the proprioceptive feedback loop between your neck and brain. This is paired with specific exercises like joint position error training and head repositioning tasks that help rebuild accuracy in how your brain senses neck position and movement.

Gait and Coordination Training

Many concussion patients struggle with walking normally, especially when asked to perform a cognitive task at the same time, such as counting backwards or carrying on a conversation. We incorporate dual-task gait training and directional change exercises to rebuild this critical skill.

Vestibular Integration

When indicated, we include gaze stabilization exercises and head movement drills that help your vestibular system recalibrate. These exercises teach your brain to maintain visual focus during head movement, which is essential for daily activities and returning to sport or work.

At-Home Exercises for Concussion Recovery

What you do between appointments matters just as much as what happens in the clinic. We prescribe specific at-home exercises tailored to your stage of recovery and the systems that need the most support. These may include:

• Balance drills: Standing on one foot with eyes open, then progressing to eyes closed or on an unstable surface like a pillow
• Cervical range of motion exercises: Slow, controlled neck rotations and side-bending to maintain mobility and reduce stiffness
• Head repositioning practice: Closing your eyes, turning your head, and returning to centre to retrain proprioceptive accuracy
• Gaze stabilization: Focusing on a stationary target while moving your head side to side or up and down
• Dual-task walking: Walking while performing a simple cognitive task to rebuild your brain’s ability to manage movement and thinking simultaneously

These exercises are designed to be safe, progressive, and performed daily. We adjust the difficulty as your symptoms improve and your nervous system adapts.

Why Rest Alone Is Not Enough

While initial rest is important in the first days following a concussion, prolonged inactivity can actually delay recovery. Current evidence supports early, guided return to activity and active rehabilitation that specifically targets the impaired systems. Waiting for symptoms to resolve on their own can leave underlying sensorimotor deficits unaddressed, making it harder to return to normal function.

A structured, progressive approach that combines in-clinic mobilization with consistent at-home exercise gives your brain and body the input they need to heal properly.

When to Seek Care After a Concussion in Fredericton

If you are experiencing any of the following after a head injury or car accident, it may be time to seek professional support:

• Persistent dizziness or feeling “off balance”
• Neck stiffness or pain that is not improving
• Difficulty concentrating while walking or in busy environments
• A general sense of not feeling right, even weeks after the initial injury
• Headaches that worsen with head or neck movement

At Fredericton Family Chiropractic, we perform a thorough assessment of your balance, coordination, cervical function, and proprioception to identify exactly where the deficits are. From there, we build a targeted rehabilitation plan that combines cervical mobilization with progressive exercise, both in the clinic and at home.

Concussion recovery is not one-size-fits-all. If you are in Fredericton and looking for hands-on, evidence-based care that goes beyond rest and medication, contact us to book an assessment.
