Introduction
Concussions are a type of traumatic brain injury (TBI) caused by an impact or jolt to the head that disrupts normal brain function.
While much attention is given to the cognitive and neurological effects of concussions, the physical impact on neck alignment and posture is equally significant but often overlooked.
Forces from a concussion frequently extend to the cervical spine, causing misalignments and musculoskeletal issues that can lead to chronic pain and dysfunction.
In this article, we explore the ways concussions impact neck alignment, posture, and overall musculoskeletal health.
Understanding Concussions
A quick walkaround:
Definition and Causes
A concussion is classified as a mild traumatic brain injury (TBI) caused by an external force to the head or rapid acceleration-deceleration movements.
These forces cause the brain to move abruptly within the skull, leading to a cascade of effects, including chemical imbalances, cellular damage, and temporary disruption of normal brain function.
This type of injury is common in activities or incidents where impacts are frequent. Sports such as football, soccer, and hockey often involve collisions that result in concussions.
Similarly, falls—particularly among children and the elderly—are a leading cause of concussions. Motor vehicle accidents and physical altercations are also notable contributors.
While the brain is the primary organ affected, the force from a concussion often extends to the neck and cervical spine.
This is due to the biomechanical connection between the head and neck, where rapid head movement can strain the cervical spine and surrounding muscles.
Consequently, neck pain, stiffness, and alignment issues are frequently reported alongside concussion symptoms.
Symptoms and Diagnosis
Concussions manifest with a variety of symptoms, including tension headaches, dizziness, confusion, memory difficulties, and nausea.
Balance disturbances and sensitivity to light or sound are also common. Additionally, postural problems, neck pain, and stiffness are frequently observed due to the involvement of the cervical spine.
Diagnosing a concussion begins with a clinical evaluation, where a healthcare provider assesses symptoms and conducts neurological exams to check cognitive and physical function.
Symptom checklists and standardized tools, such as the SCAT5 (Sport Concussion Assessment Tool), aid in diagnosis.
In some cases, imaging studies like CT scans or MRIs are used to rule out more severe injuries, such as brain hemorrhages or fractures.
Recognizing the multifaceted nature of concussions is critical for accurate diagnosis and effective management.
Cervical Spine Biomechanics
Let me walk you through the basics:
Anatomy and Function of the Cervical Spine
The cervical spine is a vital component of the skeletal system, consisting of seven vertebrae (C1 to C7) located in the neck.
These vertebrae form the uppermost segment of the spinal column, supporting the skull and allowing for a wide range of head movements, including flexion, extension, rotation, and lateral bending.
The cervical spine also encases and protects the spinal cord, a critical structure for transmitting neural signals between the brain and the rest of the body.
Surrounding the cervical spine is a network of muscles, tendons, and ligaments that provide stability and mobility.
Key structures include the intervertebral discs, which act as shock absorbers, and the ligaments that maintain vertebral alignment.
Proper alignment of the cervical spine is essential for maintaining posture, ensuring neural communication, and supporting adequate blood flow to the brain.
Misalignments can disrupt these functions, leading to pain, stiffness, and other complications.
Role in Head and Neck Stability
The cervical spine plays a central role in balancing the head, which weighs approximately 10 to 12 pounds.
It works in harmony with muscles such as the sternocleidomastoid and trapezius to distribute the head’s weight evenly and maintain an upright posture.
This intricate coordination ensures both stability and flexibility.
When the cervical spine is disrupted—such as by a concussion—the balance between the spine and its supporting structures can be compromised.
Misalignments can occur, leading to postural deviations, increased strain on muscles, and subsequent discomfort or dysfunction. Proper alignment is, therefore, crucial for overall head and neck stability.
Effects of Concussions on Neck Alignment
Here is what you can expect:
Mechanisms of Misalignment
The forces involved in a concussion often extend to the cervical spine, causing misalignments in its structure.
Research indicates that the force required to cause a concussion is typically greater than that needed to injure the neck, making neck injuries a frequent consequence of concussions (Stemper et al., 2018).
These forces can cause:
- Muscle Strain and Spasms: The sudden movement of the head can overstretch or strain neck muscles, leading to muscle spasms that pull the cervical spine out of alignment.
- Ligamentous Damage: Ligaments that hold cervical vertebrae in place may become overstretched or torn, resulting in instability.
- Joint Dysfunctions: Concussions can cause subtle misalignments in the joints between cervical vertebrae, leading to discomfort and restricted range of motion.
Postural Changes After a Concussion
Misalignments in the cervical spine often lead to postural deviations. One common issue is forward head posture (FHP), where the head protrudes forward relative to the shoulders.
This posture increases strain on the neck and upper back muscles, causing pain and fatigue. Research by Lee and Kim (2016) highlights that individuals with forward head posture often experience increased neck pain and reduced quality of life.
In addition to FHP, concussions can lead to compensatory postural changes throughout the body.
Misalignment in the cervical spine may cause adjustments in the thoracic and lumbar spine, leading to a cascade of musculoskeletal issues, including lower back pain and hip discomfort.
Real-Life Examples of Concussion-Induced Postural Issues
Let us walk you through 2 case studies:
Case Study: Athlete with Post-Concussion Neck Pain
A 19-year-old collegiate soccer player sustained a concussion during a game after a head-to-head collision. In the weeks following the injury, she experienced persistent headaches, neck pain, and difficulty concentrating.
Physical evaluation revealed forward head posture and tightness in her cervical muscles, accompanied by tenderness in the upper trapezius region.
Imaging studies showed mild misalignment in her upper cervical vertebrae (C1 and C2). A rehabilitation program was initiated, including cervical spine adjustments, myofascial release, and targeted exercises to improve posture.
After three months of therapy, her symptoms improved significantly, and her posture returned to its pre-injury state. This case underscores the importance of addressing cervical spine alignment as part of concussion recovery.
Case Study: Office Worker with Persistent Postural Changes
A 35-year-old office worker suffered a concussion after slipping and hitting his head during a fall. Following the injury, he developed chronic neck stiffness, difficulty maintaining an upright posture, and frequent headaches.
An ergonomic assessment of his workstation revealed poor sitting posture, which exacerbated his symptoms.
Physical therapy focused on correcting his neck alignment and improving his sitting posture through core-strengthening exercises and ergonomic adjustments.
His program included regular breaks from sitting, stretching routines, and the use of a lumbar support cushion.
Over six months, his posture improved, and his headaches became less frequent. This case illustrates how concussions can lead to long-term postural issues if not addressed early.
Conclusion
Concussions, while primarily recognized as brain injuries, have profound effects on neck alignment and posture.
The forces involved in a concussion can cause misalignments in the cervical spine, leading to muscle strain, ligament damage, and joint dysfunction.
These changes often result in postural deviations such as forward head posture, which can cascade into broader musculoskeletal issues.
Real-life examples, such as the athlete with persistent neck pain and the office worker with chronic postural changes, highlight the importance of early intervention.
Addressing cervical spine alignment and posture through physical therapy, ergonomic adjustments, and targeted exercises is crucial for comprehensive concussion management.
Recognizing the impact of concussions on neck alignment is essential for improving recovery outcomes and enhancing overall quality of life.
