Whiplash (Neck Strain)

What is Whiplash (Neck Whip Injury)?

Whiplash is caused by abrupt changes in movement that force the neck and upper spine into injury-inducing motions. This can cause a type of neck sprain. The term "whiplash" encompasses a variety of effects, leading experts to refer to related conditions as Whiplash Associated Disorders. Whiplash can also occur from sudden movements in any direction.

As a neck injury, whiplash must initially be handled by healthcare teams, and it is generally treated as an emergency. Professionals approach patients with extreme caution until the injury is confirmed, treated, or stabilized.

Commonly stemming from rear-end car accidents, this condition can also arise from sports accidents, physical assault, or falls. It is referred to as a neck sprain or injury.

Many patients with whiplash are treated with a plan that includes painkillers and exercise, and they generally recover within a few weeks. However, some may experience long-term complications.

Causes of Whiplash (Neck Whip Injury)

Whiplash generally occurs when the head is abruptly thrown backward and then forward forcefully. This typically results from a rear-end car accident and can damage neck muscles and tissues. Other common causes of whiplash include:

• Motor vehicle accidents
• Contact sports
• Riding roller coasters
• Physical abuse or assault

Symptoms of Whiplash (Neck Whip Injury)

The severity of whiplash symptoms varies depending on the intensity of the neck extension or compression during impact. Symptoms of whiplash appear at various times. Some symptoms may appear immediately, while others may take at least 12 hours to emerge, with the full onset sometimes exceeding 24 hours.

Given the variety of effects, experts have established a grading system for disorders associated with whiplash called the Quebec Classification. According to this grading, possible symptoms include:

Grade 1

At this level, the individual feels no pain or shows no signs of injury.

Grade 2

This is the first level where the individual feels pain. Associated symptoms include:

• Stiffness during movement
• Tenderness to touch around the injury

Grade 3

This level is the first to show physical signs of an injury, along with the pain and symptoms of a second-grade whiplash. Symptoms include:

• Pain spreading to the head, face, shoulders, and back
• Muscle spasms that make moving or turning the head and neck difficult
• Physical signs of injury such as bruising, swelling, and sensitivity to touch around the affected area

Grade 4

At this stage, neurological symptoms begin to appear in whiplash cases. These are caused by swelling or inflammation disrupting nerve signals passing to or from the brain through the injured area. Symptoms include:

• Muscle weakness
• Numbness in the neck, upper back, shoulders, and arms
• Burning, tingling, and pins and needles sensations in the upper areas of the neck, back, shoulders, and arms
• Headaches
• Visual disturbances due to disorders in the reflexes that normally keep the eyes stable when the head and neck move
• Hoarseness or loss of voice
• Difficulty swallowing
• Dizziness
• Vertigo

Grade 5

The most severe form of the condition, Grade 4, not only includes all the symptoms mentioned above but also involves fractures or misalignment of the cervical vertebrae, potentially compressing nearby nerves.

Whiplash (Neck Whip Injury) Diagnostic Criteria

Whiplash is considered a diagnosis of exclusion. Therefore, experts often only diagnose it after ruling out more serious conditions or other possible causes. To exclude other conditions, diagnostic tests, imaging scans, and physical and neurological examinations are necessary. It's also important to gather information about the symptoms and factors like traffic accidents that could have led to the situation.

Physical and Neurological Examination

During an examination, specialists will touch and move the head, neck, and arms to check the following:

• Range of motion in the neck and shoulders
• Movements that cause pain or increase existing pain
• Sensitivity in the neck, shoulders, or back
• Reflexes, strength, and sensation in the limbs

Imaging Tests

While whiplash injuries may not be visible in imaging tests, these tests can help rule out other factors that could worsen neck pain. Possible imaging tests include:

• X-ray
• CT scan
• MRI

Whiplash (Neck Whip Injury) Treatment Methods

The goals of whiplash treatment include:

• Pain management
• Restoring neck mobility
• Returning to normal activities

The treatment plan varies depending on the severity of whiplash. While over-the-counter pain relievers may suffice for some, others may require physical therapy or even surgery.

Pain Management

To alleviate pain, one or more of the following treatments may help:

Rest

Resting during the initial few days after injury can help ease the pain, but too much rest may delay recovery.

Hot or Cold Application

Applying heat or cold compresses to the neck for 15 minutes every three hours can reduce pain and improve comfort.

Over-the-Counter Pain Relievers

Medications such as acetaminophen and ibuprofen are generally effective for managing mild to moderate pain.

Prescription Medications

For severe pain, prescription medications such as certain antidepressants may be prescribed to ease nerve pain.

Muscle Relaxants

Short-term use of muscle relaxants can help relieve pain by easing muscle tension. These drugs may also cause drowsiness, making them ideal for patients who have difficulty sleeping due to pain.

Numbing Injections

Injecting lidocaine into painful muscle areas can alleviate pain, especially recommended during physical therapy.

Exercise

Specialists may recommend various stretching and movement exercises that patients can perform at home to restore neck mobility and help return to normal activities. Applying moist heat to the painful area or taking a warm shower before exercises is advised.

Recommended exercises include:

• Turning the neck to both sides
• Tilting the head from one side to the other
• Tucking the chin to the chest to stretch the neck muscles
• Rolling the shoulders

Physical Therapy

Physical therapy may be recommended if pain persists or if assistance is needed during home exercises. Physical therapists help patients improve their strength, posture, and regain movements, which can prevent further injury.

In some cases, a procedure called Transcutaneous Electrical Nerve Stimulation (TENS) is used. TENS delivers mild electrical currents to the skin. Limited research suggests this treatment can alleviate neck pain and increase muscle strength quickly.

The number and duration of physical therapy sessions vary based on patient needs. Exercises that patients can perform at home may also support physical therapy.

Neck Braces

Soft foam collars have been used for a long time to alleviate pain in whiplash treatment. However, studies suggest that prolonged immobilization of the neck muscles can weaken them and slow recovery.

Using supports to restrict movement can help reduce pain immediately after the injury and may also improve sleep at night. However, experts disagree on how long the support should be used. While some suggest that neck braces should not be used for more than 72 hours, others believe they can be worn for several weeks. Therefore, it is important to follow the doctor’s recommendations on the duration of use.

Radiofrequency Nerve Ablation (RF)

RF, a treatment method for chronic pain, prevents nerves in the affected area from sending pain signals. This technique is particularly used when an injury has caused nerve damage or when nerves send excessive pain signals. The treatment involves heating and deliberately damaging the targeted nerves with RF energy, effectively stopping the pain signals. This can reduce pain for several months.

Spinal Surgery

In rare cases, a whiplash injury may require surgery, such as when ligaments are torn or the spine is fractured. Spinal surgery stabilizes the affected areas of the spine to prevent further nerve damage.

Alternative Medicine

Non-traditional treatments can be tried for whiplash pain, although there is insufficient research on their effectiveness. Alternative methods for managing pain include:

Acupuncture

This treatment involves inserting thin needles into specific areas of the skin and can provide some relief from neck pain.

Chiropractic Care

Administered by a chiropractor, this method involves manipulations to the joints. Combining chiropractic care with exercises or physical therapy can help alleviate pain. While generally safe, spinal manipulation can sometimes cause minor issues like numbness or dizziness and rarely, tissue damage.

Massage

Neck massages can provide temporary relief from neck pain resulting from a whiplash injury.

Mind-Body Therapies

Gentle movement-based exercises like Tai Chi, Qigong, or yoga, focusing on breath and movement, can help alleviate pain and reduce stiffness.

Recovery Process for Whiplash (Neck Whip Injury)

The recovery timeline for whiplash varies depending on the patient, treatment methods, cause of injury, personal circumstances, and health history. Specialists provide more information about the likely timeline for recovery.

Patients, particularly with Grade 1 or 2 injuries, can often manage on their own. Those with such grades can alleviate their pain with heat application, over-the-counter pain relievers, and rest. However, if pain is moderate or home treatments do not ease the pain, consulting a doctor is necessary.

If the impact causing the whiplash also leads to loss of consciousness or fainting, medical attention should be sought immediately. Similarly, if neurological symptoms appear, self-treatment is not advisable.

Symptoms like fainting, dizziness, headaches, tingling, numbness, weakness, difficulty swallowing, or speaking require urgent medical attention, as they may also indicate a concussion or traumatic brain injury, both of which are potentially life-threatening.

Effects of Whiplash (Neck Whip Injury) on the Body

Whiplash occurs due to inertia affecting the human body, similar to the sudden stopping of a moving car when a driver hits the brakes. Inertia causes the body to continue moving forward even when the car stops and is also why the body is thrust against the seat when the driver accelerates suddenly from a stop.

Just as in the analogy, the brain is like a passenger within the skull. Sharp and sudden movements can cause the brain to impact the inside of the skull, leading to brain injuries. The neck acts as a shock absorber for the brain, naturally compressing, extending, or rotating to reduce the effects of sudden movements on the brain.

Whiplash results from inertia causing the head, neck, and body to move at different speeds, leading to excessive compression or extension of the neck or straining of the spinal muscles, ligaments, and bones beyond their tolerance.

The sharper and stronger the movement, the greater the force on the neck. Thus, whiplash injuries can range from mild to severe, although even mild impacts can lead to moderate or severe whiplash. Experts are still unsure why this is the case.

Complications of Whiplash (Neck Whip Injury)

Many individuals with whiplash feel better within a few weeks, typically without lasting effects. However, some may continue to experience pain months or even years after the injury.

Predicting the outcome of whiplash recovery is challenging. Generally, if initial symptoms are intense or develop quickly, the pain is likely to be long-term. Long-term pain may also include the following:

• Severe neck pain
• Reduced range of motion
• Pain that spreads to the arms

The presence of the following risk factors is associated with worse outcomes:

• Previous neck injuries
• Older age
• Existing pain in the lower back and neck
• Injury at high speeds
