Car Accident Injuries: Neck Muscles Affected by Whiplash

 

Unfortunately, car accidents have become common occurences on Florida roadways. Reasons include weather hazards, busy roadways, dangerous road conditions, negligence of drivers, and many others. A severe car accident can take a toll on the victim’s life. The sudden physical force caused by a crash violently shakes the car, causing serious injuries and damage to those inside the vehicle. One of the most commonly suffered car accident injuries is whiplash. In whiplash, the neck ligaments and muscles sustain damage due to the intense back-and-forth motion in the crash. Victims may suffer from chronic pain for months or even years if the neck muscles affected by whiplash are not addressed in time. The force causes damage to nerves and bones in the neck, and also to the discs in the cervical spine. Whiplash is treatable, but the potential symptoms need to be minutely taken into notice after the accident.

 

The neck muscles injured by whiplash include the sternocleidomastoid, splenius capitis, and trapezius. These muscles play a key role in head movement. When these muscles suffer rapid acceleration and deceleration due to whiplash, they result in strain, sprain, and other trauma. In this blog, we will discuss the muscles affected by whiplash in a motor vehicle accident and how to address the consequences of serious injuries.

 

What is Whiplash? How Does It Affect the Victim’s Neck Muscles?

 

Whiplash is a common soft-tissue neck injury caused by a car crash. The sudden back-and-forth movements caused by a car accident force the neck and spine to shake uncontrollably, causing a neck sprain. Whiplash moves the victim’s head back and then thrusts forward. The damage to the neck muscles caused by the whiplash is also known as “whiplash-associated disorders”. Victims can sustain the injury with sudden movement changes in any direction. As the force impacts a delicate area like the neck, victims require emergency medical attention.

In most cases, whiplash injuries occur in a car accident due to the sudden jerk and force. The random acceleration-deceleration motion results in a number of symptoms and complexities. Whiplash can damage a wide range of muscles and lead to a more painful state beyond discomfort in the neck. The complications of the injuries leave their impact on different body parts. The sudden motion stretches and strains the soft tissues. The injury often results in pain, stiffness, and a range of other symptoms. Some of the common whiplash symptoms include neck pain, headaches, and limited range of motion. The pain spreads in the surrounding areas beyond the neck. The common symptoms of whiplash are -

 

• Severe neck pain and restricted range of motion are stark whiplash signs. The harsh motion strains the neck ligaments. The force causes damage and limits the range of activities.

 

• When the intricate balance mechanism breaks down, the victim may suffer dizziness and numbness. The spinning sensation is also known as vertigo.

 

• One common symptom is headache, which can be intense and last for a range of durations. The headache is often a result of muscle tension, extreme nerve stimulation, and other internal impacts of the injuries on the body.

 

• The trauma caused by the accident may affect the temporomandibular joint (TMJ). The injury causes jaw pain where the victim finds it hard to open and close the mouth. It’s a crucial injury indicator, yet the victims seem to overlook it.

 

• Whiplash damages a wide range of muscles. The force caused by the car accident damages the shoulder and upper back tissues. The condition brings extreme pain and discomfort to the neck muscles affected by whiplash.

 

• The constant pain and soreness in the muscles result in extreme fatigue. It becomes difficult to sleep peacefully at night. Considering the tiredness, sleep disorders can further disturb the recovery. 

 

• Whiplash may affect the neck nerves in some cases. Nerve damage may result in numb or tingling sensations in the arms and hands. The injury occurs when the nerves are compressed due to an accidental force.

 

• Along with the physical symptoms, cognitive problems may appear. The victims may find it difficult to concentrate or remember things correctly. The nerve damage may disrupt the victim’s everyday activities and work performance. 

 

What Are the Primary Neck Muscles Affected by Whiplash?

 

When a victim suffers neck muscle injuries in a car accident, it can lead to heavy discomfort. A certain set of neck muscles plays a key role in aggravating the symptoms. It’s vital to recognize the primary muscles damaged by a whiplash injury. In this section, we will talk about the main muscles and how whiplash affects them in a car injury.

 

 Scalene Muscles

 

Scalene muscles are found on the sides of the neck. They are of three types: anterior, middle, and posterior. When whiplash occurs, the scalene muscles come to the front. The muscles provide support. The sudden force of a car accident results in spasms and stiffness. The victims need expert medical care and rehabilitation support to recover from the pain and discomfort associated with the injury.

 

Sternocleidomastoid Muscles

 

The sternocleidomastoid is one of the primary neck muscles affected by whiplash. The muscle extends to the mastoid behind the ear. The muscle originates from two heads - the sternum (manubrium sterni) and the clavicle. The muscle helps in head rotation and flexion. When an accident occurs, the muscle becomes active in stabilizing the force. Meanwhile, the muscle suffers a strain. It’s important to understand the role of the sternocleidomastoid muscles affected by whiplash.

 

Trapezius

 

The trapezius is a big, triangular muscle found in the upper back. It is expansive and quite complex in structure. The trapezius helps with the range of motion. When an accident occurs, the muscle tries to stabilize and bring the impact under control. The trapezius plays a key role when it comes to the muscles affected by whiplash. The upper fibers extend to the base of the skull. The middle and lower fibers descend along the spine. Whiplash not only results in neck pain but also shoulder and upper back pain. 

 

What Are the Secondary Neck Muscles Affected by Whiplash?

 

In whiplash injury, the immediate focus is on the primary muscles, but that doesn’t undermine the role of the secondary ones. The secondary neck muscles provide support as the body tries to withstand the sudden back-and-forth motion. The muscles support the neck structure after an accident. When the secondary muscles suffer damage by whiplash, the consequences last for a long time and surface in the form of a range of symptoms.

 

Splenius Capitis

 

 

 

The splenius capitis is a neck muscle that helps with head and neck movement. When the muscle suffers an injury, it results in pain and limited mobility.

 

Levator Scapulae

 

The muscle flows along the sides and back of the neck. It helps move and lift the shoulder blades. When confronted with a whiplash injury, the muscles shrink in response to the force, which adds to the neck pain and stiffness.

 

Multifidus

 

 

The multifidus muscles run along the spine, helping stabilize it. Whiplash causes tension. When the muscles are under pressure, they can cause lower back pain and neck stiffness. 

 

Whiplash Injuries: What Damages the Victim’s Body Suffers

 

Whiplash in a car accident happens as per the law of inertia. The victim suffers injuries when the driver suddenly brakes the car to avoid the accident while the vehicle is still moving. The abrupt motion pushes the upper body forward when the car has stopped. That’s how the law of inertia works. Sudden and forceful movements can cause the victim’s brain to collide against the inside of the skull, causing internal injury. The neck is a shock absorber for the head. It compresses, twists, and extends to reduce the strong impact of sudden movements on the brain.

 

Whiplash hits when inertia throws the victim’s head, neck, and whole body in different directions at different speeds. The power forces your neck to compress or expand too fast in ways that pressurize the bones, muscles, and ligaments of your spine beyond what the body can tolerate.

The more intense and stronger the movement, the more force is on the neck, resulting in the neck muscles being affected by whiplash. Whiplash injuries can be minor to extreme. Even a low force level may cause medium to severe whiplash. In the worst cases, whiplash can break the vertebrae and damage the spinal cord and the connected nerves.

 

Whiplash Symptoms to Check After A Car Crash

 

The symptoms of whiplash vary based on the force and severity of whiplash and how intensely the neck was compressed. The more the compression or the extension, the deeper the damage. It’s crucial to detect the whiplash symptoms after one has been involved in a car accident. Whiplash symptoms appear differently with time. Some symptoms may occur immediately after a car crash, while other symptoms take around 12 hours to surface. For some victims, the whiplash symptoms may take a day or even a few days to appear.

 

Neck muscles affected by whiplash leave several impacts on the victims’ bodies. Medical professionals have created a Grade system to check the severity of the Whiplash-Associated Disorders. The Grades and the symptoms are as follows -

 

 

Grade 0 - No Injury

 

In Grade 0, the victim neither feels any pain nor shows any signs.

 

Grade 1: Only pain

 

At this level of whiplash, the victim feels pain, stiffness in movements, and tenderness when the injured area is touched.

 

Grade 2: Pain with the injury signs

 

At Grade 2, physical signs of the injuries appear in the victim’s body. The symptoms may include -

• Pain spread through the head, face, shoulder, and back
• Muscle spasms are causing your head and neck to be hard to turn
• Injury signs like bruises, inflammation, and tenderness show up when touched

 

Grade 3: Pain, injury signs, and impact on the nervous system

 

Whiplash at Grade 3 appears with neurological symptoms. The swollen areas affect the nerve signals traveling through the body from the brain. The core signs are -

 

• Headaches 
• Weak muscles
• Numbness in the neck, back, shoulders, and upper arms
• Burning and tingling symptoms in your neck, upper back and arms, and shoulders.
• Vision problems due to the obstruction in the reflexes
• Vertigo
• Loss of voice and trouble in swallowing water or food. 

 

Grade 4: Intense pain and signs of severe neurological damage.

 

Grade 4 is the last and utmost level of whiplash-associated disorders. At this stage, the victim suffers from all the symptoms simultaneously, especially neurological signs. When the neurological symptoms are extreme, it indicates a fracture or misalignment of the neck vertebra.

 

Final Takeaway

 

It’s critical to assess the complexities of which muscles have incurred whiplash injuries to check the damage to the victim’s musculoskeletal structure. The injury impacts the primary muscles of the sternocleidomastoid, scalene, and trapezius. These muscles are the first ones to counter the pressure and tension. After a car crash, it’s essential to find immediate medical attention to identify the injury and examine the extent of the damage. The healthcare professionals understand the intricacies of the injury and offer them an effective mode of recovery. At Injury Rely, the expert doctors personalize the healthcare and treatment strategies for each victim based on the extent of their injuries to address the symptoms with proven therapeutic methods for a faster and potent recovery.
