The accident-type most-associated with whiplash is being rear-ended. Let us take a glance at how this kind of accident happens. Most people think that when you could be rear ended, your head flies back. Although that is the logical way to consider the harm (it’s also how I will discuss it most of the time), it is not technically accurate.
Process of Whiplash Injury
When you are rear-ended what happens is that your body is driven out from under your head. Although there is a great deal of soft tissue stretching that occurs in the soft tissues (LIGAMENTS, TENDONS, MUSCLES, and particularly FASCIA) as your body travels forward at a significantly higher velocity than your head; at some point, these “soft tissues” cannot stretch anymore. This is the first point at which microscopic tissue tearing occurs. Realize that this is the beginning of the injury process. The body will be gradually caught up to by the head, and subsequently overshoot it at an extremely accelerated velocity, all in a fraction of a second.
The head is now accelerating forward faster than your entire body. When the body comes to a stop (i.e. your vehicle slams into whatever is in front of it), the head will continue to travel forward. This is actually where the term “whiplash” comes from, and where it occurs. It’s exactly the principle of physics that results in the tip of a bullwhip to ‘crack’ as it breaks the sound barrier. If this type of ‘whipping’ motion occurs in the neck, it can result in a great deal of soft tissue damage and subsequent formation of fibrosis and scar tissue. Additionally, it may lead to a great deal of occult (hidden) brain and nerve system trauma.
When tissue tears, it ordinarily doesn’t tear like we think of things tearing, in half. As a matter of fact, when you take a look at pulled muscles, these are actually pulled, over-stretched, or microscopically torn fascia. Fascia is the thin membrane that tightly surrounds the muscle. Fascial tearing and the subsequent fascial adhesions present a double-edged sword as far as chronic pain is concerned.
Surround your neck with too much scar tissue, and there is no way your neck will move normally as it did before the motor vehicle accident. Unfortunately, degeneration is caused by abnormal motion, and abnormal joint motion is caused by degeneration. Repeat ad infinitum. Whether or not this cycle was launched by an MVA is immaterial at this stage. The process leads to chronic pain. People who are living inside of this vicious cycle know. Same evaluations, same results. If you’ve been involved in an automobile accident and are experiencing neck pain or other symptoms due to suspected cervical spine damage or injury, seek immediate medical attention.

Whiplash, among other automobile accident injuries, are frequently reported by victims of an auto collision, regardless of the severity and grade of the accident. The sheer force of an impact can cause damage or injury to the cervical spine, as well as to the rest of the spine. Whiplash is generally the result of an abrupt, back-and-forth jolt of the head and neck in any direction. Fortunately, a variety of treatments are available to treat automobile accident injuries.
Each year in america there are between 6.5 million and 7 million MVA’s affecting many individuals. Of those accidents, about three million involve some kind of bodily injury. About two thirds of these injuries, while not debilitating, are permanent. This means that if you play the odds, you’ll be during the course of your lifetime in 4 or 5 car accidents. They are undoubtedly the major cause although MVA’s are certainly not the sole cause of injuries, such as whiplash.
What is the significant whiplash sign we look for as far as imaging is concerned? A simple neutral lateral x-ray of the cervical spine is about as good as anything to demonstrate the extent of damage or injury.
When an individual experiences whiplash, their fascia is often damaged or injured as their head slams backwards. Sooner or later the individual begins to get neck pain, headaches, and a loss of range of motion in their neck. The problem is that a Fascial Adhesion in the SCM may be pulling on their neck. A restriction (Fascial Adhesion) in the SCM is going to pull the head forward.
Normal Cervical Curves
Although you should not have spinal curves that run from 1 side of your body to the other (Scoliosis), it’s absolutely crucial to have the proper spinal curves that run from front to back. The normal front-to-back curve in your neck, should be the same as the front-to-back curve in your low back (lordosis) — the opposite of the curve in your mid back (kyphosis). Normal curves allow for normal motion, they act as shock absorbers. Think for a moment about it. A normal curve will dissipate much of the force, spreading it out like a spring when you walk down the sidewalk.
Abnormal Cervical Curves
Abnormal curves of the cervical spine (neck) come in two forms. You have the loss of cervical lordosis. This is the “Military Neck” you see in the first x-ray. Secondly, you get a complete reversal of the lordotic curve (second x-ray). These are some of the steps on the road to Degenerative Arthritis.
For those of you understanding the nature whiplash injury and the NEW MODEL of Repair and Tissue Healing, this picture of the PLATYSMA MUSCLE should help. The Platysma is a thin muscle that covers the entire front portion of the neck. It is likewise covered in Fascia. This is just one more piece of the puzzle so far as explaining the Chronic Pain people struggle with after a whiplash injury — by imaging which is always negative, pain that is not explained. And like SCM Muscles that are injured, it helps to explain the cervical curves. It pulls, as it restricts, and as it pulls, the head will come. Think that Forward Head Posture is no big deal? THINK AGAIN.

Whiplash is generally the result of an abrupt, back-and-forth jolt of the head and neck in any direction. Fortunately, a variety of treatments are available to treat automobile accident injuries.
Automobile accidents are one of the leading causes of spine injuries and are responsible for more than 40 percent of injuries every year. That is a troubling statistic. Because automobile accidents cannot always be prevented, having the right understanding of spine injuries can allow people to recognize injury and seek proper treatment.
The spine is an intricate structure, but additionally it is delicate. The spine isn’t designed to withstand the harmful effects of an automobile accident. Regrettably, spine and neck injuries are common during auto collisions; the impact damages the muscles and the ligaments in the back, and the facet joints bear the brunt of the force. This could result in injuries, such as compression fractures, disk herniation, whiplash, and spondylolisthesis.
It is essential to be able to spot the symptoms of damage or injury, so if you or someone you love is hurt, its important to understand what steps you should follow for proper care. Some auto accidents may be made worse when the injured individual is moved. You should seek the assistance of a medical professional if you experience back or neck pain following an automobile collision. A muscle strain may heal by itself, but if neck or back pain persists due to a much more serious condition or injury, the affected individual could feel pain for months or years if left untreated.
Identifying Damage or Injury
How do you know if back or neck pain is simply a muscle strain, or even a more significant injury or condition? Until you are evaluated by a healthcare specialist, you likely won’t know for certain, however there are a number of indications that may indicate that aid is needed. A few of the neck and back injuries include:
Whiplash
Whiplash is more common during rear-end collisions, as the force from impact suddenly pushes the head backward, then forward, much like the movement of hammering a whip. Front-end collisions generally do not result in whiplash, as the headrest often stops the motion of the head and neck. Symptoms of whiplash will appear within one day of the crash, and might include stiffness and pain in the neck, headaches which are often at the bottom of the skull, dizziness, blurred vision, and fatigue. Sometimes, an individual with whiplash may experience difficulty concentrating, memory problems, ringing in the ears, difficulty sleeping, and irritability.
Spinal Fractures
Compression fractures are common in the thoracic and cervical spine (middle and lower back) after a car crash. While the entire body is held in place with a seatbelt, during impact, the body may be thrown forward. This can pull on the vertebrae. As the vertebrae may rarely move, in some cases, spinal fractures may result in spinal cord injuries. Those with spinal cord injuries may experience tingling, numbness, weakness, or loss of bowel and bladder control, although the main symptom of a spinal fracture is mild to severe back pain that interferes with movement. When a fracture is suspected, it is important not to move the injured person; harm could be caused by motion.
Spondylolisthesis
Spondylolisithesis occurs when a vertebra shifts from place because of a stress fracture in bone. The bone that is displaced can press on the nerves or narrow the spinal canal, causing pain, numbness, or weakness in the buttock or leg, and trouble walking. In extreme cases, it may lead to loss of bladder or bowel control. Some people don’t experience symptoms until many years later, or experience no symptoms in any way.
Disc Herniation
Considering that the discs absorb the vast majority of the impact to the spine, it is possible to get a disc to herniate through an automobile crash. A disc is herniated if its tender core pushes through a little crack in the outside of the disc, irritating the nerves. Many people today experience no symptoms, but others might experience leg or arm pain, depending on the location of the herniated disc, and might experience tingling, numbness, or weakness in the region.
What to Do if You’ve Got a Spinal Injury
Should you encounter any back or neck pain at all following a car crash, you should be evaluated by a healthcare professional to rule out any severe injury. But, it is important to get medical care immediately in case you experience tingling, numbness, fatigue, or lack of bowel or bladder control. These are indications of a more serious injury that has to be addressed immediately.

Spinal cord injury (SCI) can have many causes. The way a person’s injury affects them can differ depending on the origin of SCI. SCI can generally be described as being ‘traumatic’ or due to a trauma, or ‘non-traumatic’ being due to other causes.
Spinal cord injuries occur in an assortment of ways. In adults, damage to the spinal column is usually involved and the cord is affected, bruised, stretched or compacted due to movement or an external force. Wear and tear on the spinal column, can lead to narrowing of the canal called stenosis. This results in pressure on the spinal nerves and the spinal cord, causing loss of function. In children, a spinal cord injury occurs by an over-stretching of the spinal cord.
Automobile accidents involving pedestrians or occupants, falls, sport-related accidents and diving into shallow water are considered to be the most common cause of traumatic SCI.
Spinal cord damage can be caused by the following kinds of injuries:
Flexion Injuries
Flexion injuries occur when there is a forcible forward movement of the head. This results in injury to the vertebrae in the neck (cervical) area of the spinal column. The vertebrae then impact on the spinal cord, causing damage. Spinal ligaments are often torn. These types of injuries occur in auto accidents.
Rotation Injuries
Rotation injuries occur alongside an injury, often where there is rotation of the spinal column. This leads to an associated injury of the spinal cord. Ligaments are often torn where the side rotation injuries happen in automobile accidents. They can also occur with people in motorcycle accidents, and wearing lap seat belts.
Compression Injuries
Compression injuries occur in diving accidents, where the force is transmitted through the head; or falls from a height, where the force is transmitted through the base of the spine or limbs. Impact causes the vertebrae commonly in the cervical or lower thoracic and lumbar region, to fracture into pieces and protrude into the spinal canal, damaging the spinal cord. The discs may be displaced and protrude into the spinal canal.
Hyperextension Injuries
Hyperextension injuries occur during an incident, such as a fall, where the neck is extended in a backward direction, stretching the cord. The spinal cord is damaged by the opening up of the discs and stretching of the ligaments if there’s minimal damage to the spinal column. This injury is often seen in people, and those injured in assaults and auto accidents. Hyperextension of the neck is the way children damage their spinal cords. The force of the trauma causes stretching of the spinal cord, although there’s often no or little damage to the spinal column.
Penetrating Injuries
Penetrating injuries occur when the spinal cord is penetrated by an object such as a knife or bullet. This type of injury can occur at any level of the spinal column and is often not associated with column damage.
Whether an injury is caused by events that are traumatic or non-traumatic, a person with a SCI has the ability to benefit from a variety of treatment options and rehabilitation, performed by a qualified and experienced healthcare professional. Research has indicated that the outcomes for people with a SCI are better if they have rehabilitation in a specialist unit as opposed to a general rehabilitation unit.

Whiplash is generally the result of an abrupt, back-and-forth jolt of the head and neck in any direction. Fortunately, a variety of treatments are available to treat automobile accident injuries.
The cervical spine is C shaped, with its curve facing towards the rear of neck. The upper part of the spine in the neck is called the cervical spine and it’s composed of 7 cervical vertebra. A healthy cervical spine has a lordotic curve and it is anatomically important to bear the head’s weight.
Reduction of cervical lordosis can result in straightening of the cervical spine or in severe cases it may reverse the curve. The condition is also known as kyphosis. Loss of cervical lordosis may lead to stiffness and pain in the neck. It may also lead to referred pain in the hand, vertigo and many other symptoms.
Improper posture and muscular spasm are two important causes for reduction of cervical curvature. The problem is usually detected on X-rays of the cervical spine and it should be treated soon to prevent further deterioration and complications in the future.
Causes of Loss of Cervical Lordosis
Loss of cervical curvature usually occurs in adults. Children suffer from this issue as well although it is rare. Both women and men are equally affected. The condition is associated with long standing spasms of muscles in the neck.
Poor neck posture is often the only cause in young individuals. Working on a computer for long periods or doing desk work for long time without taking break can strain the muscles of the neck. The muscles cause a pull on the cervical vertebra. Prolonged pull will automatically disturb the normal alignment of the cervical spine. Injury to cervical spine may also lead to loss of cervical lordosis. A whiplash injury from automobile accident trauma on the neck can contribute to muscle strain and loss of curvature of the cervical spine.
Osteoporosis is another important factor that might cause abnormality in cervical spine curvature. It is mostly seen among elderly individuals. In osteoporosis the bone density of the vertebrae is lost. The weight of normal wear and tear may put pressure on the spine. Obesity and hereditary skeletal disorders, such as achondroplacia, can also change the curvature of the spine. Other less common causes of loss of cervical lordosis include tumor of cervical spine, systemic disease such as ankylosing spondylitis etc.. Radiotherapy for cancer between can also cause loss of spine curvature.
Loss Of Cervical Lordosis Symptoms
Loss of cervical lordosis involves an ongoing gradual procedure. It is a phenomenon. In its start phase the condition remains silent. This means there are no symptoms. And it’s detected accidentally on X-ray meant for some other purpose. After months or years, the individual may present complaints such as pain and stiffness in the neck.
A normal cervical lordosis has a 30 to 40 degree curve. Once the curve gets lesser than 20 degrees, the patient may complain about neck pain. It may lead to tingling in hands and fingers and may lead to cervical disc degeneration. These symptoms aren’t exactly those from compression of cervical vertebra, but because of pinched nerve because of loss of lordosis.
Loss of cervical lordosis also results in tension in the spinal cord and carotid blood vessels which supply blood to the head. Improper blood flow in the brain can result in dizziness, headaches, confusion, tinnitus etc..
Treatment for Loss of Cervical Lordosis
Loss of cervical lordosis may be detected on physical examination from diagnostic tests such as X-ray and MRI of the cervical spine. These evaluations are important to know the magnitude of loss of lordosis and nerve damage.
Medical treatment is only required when pain and stiffness are present. Muscle relaxants and pain killers will help to reduce spasms and pain of neck muscles. This increase the variety of motion of neck and will alleviate the distress.
Once first acute symptoms are relieved patient should start physiotherapy exercises aimed at strengthening the neck muscles and improvement of posture. A simple neck exercise is to bend the head forward and backward. Second exercise is to turn the neck and head sideways five to six times in a day. Severe case of loss of cervical lordosis may require the individual to wear a neck brace during day time and support pillows while sleeping. Both will help to restore the altered curvature of the spine.

Whiplash, among other automobile accident injuries, are frequently reported by victims of an auto collision, regardless of the severity and grade of the accident.

Whiplash is generally the result of an abrupt, back-and-forth jolt of the head and neck in any direction. Fortunately, a variety of treatments are available to treat automobile accident injuries.
The normal cervical lordosis is the natural curve of the neck when viewed from the side, the convexity is on the front and the concavity is on the back.
This curve starts to form as early as 10 months of development and is cemented during adolescence and infancy. Holding a child’s head in extension is quite important for infants as it encourages the normal curvature of the neck. Loss of lordosis can begin in early childhood, however, whiplash from automobile accidents, stress, injuries from falls and sports injuries can cause this issue in adulthood. Unfortunately, many of our “normal” daily tasks may also decrease the cervical lordosis, like viewing low lying computer screens (below eye level), sleeping with two pillows, as well as sitting in a recliner.
Many studies are demonstrating a clear causal connection between loss of lordosis and neck complaints, including neck stiffness and pain, headaches, premature degeneration, disc herniation, and numbness/tingling or weakness in the arms. A study from 1974 showed that a sharp reversal of the curve would lead to degenerative changes in 60 percent of patients. Literally, a reversed curve causes arthritis in the neck. A study from 2005 in the Journal of Manipulative and Physiologic Therapeutics found:
“The odds that a patient with cervical pain had a lordosis of 0 degrees or less was 18 times greater than for a patient having a non-cervical complaint. Patients with cervical pain had less lordosis and this was consistent over all age ranges” The authors of this study went so far as to recommend “Maintenance of a lordosis could be a clinical goal for chiropractic treatment”
Effects of Loss of Cervical Lordosis
But why neck pain? What does loss of the curve do to cause pain? Tingling? Numbness? Headaches? It’s actually very simple. Where they would not bear weight weight bearing stress is placed by A lack of lordosis onto joints at the neck. This causes muscle spasm, stiffness, and inflammation to stabilize the region. Muscles in the upper part of the neck then irritate nerves that travel up and over your head into the scalp. Supporting ligaments in the back of the neck stretch and those in front contract, working to further stabilize the neck in this unnatural posture, as time progresses. Weight is born mainly on the lower segments of the neck (C5-7), which then typically degenerate first. Arthritic spurring progresses in these dysfunctional segments, which could then impinge the exiting nerve roots and cause symptoms in the arms and hands like tingling, numbness, electrical shocks, and fatigue.
Tension After Auto Accident
As the curve becomes kyphotic, other neurologic complaints can attest. The spinal cord is tethered at the top by its attachment to the brain, and in the bottom by the lumbar nerve roots and meningeal attachment to your tailbone. The spinal cord is tractioned and forced against the back of the bodies of the vertebrae in the neck when the ordinary throat curve is reversed. This can cause sensory difficulties anywhere in the body as the pathways for sensation are located in the rear of the cord, and thus are affected by traction. The motor pathways are in the front of the cord and are compressed rather than stretched. Compression of a nerve is never a good thing, particularly when it’s the cord.
What many folks do not know is that most nerve fibers are insulated by a fatty layer called “myelin.” This layer works to allow the signal the nerve creates to travel at faster speeds than it could. Compression of a nerve may result in the death of those cells which maintain this layer; causing the signal the nerve carries to be permanently slower and thus not produce its intended effect. An animal study from 2005 hunted to replicate demyelination (a common diagnostic criteria for Multiple Sclerosis) via cervical kyphosis in Japanese small game fowls. That study’s results were startling. The authors concluded:
“Progressive kyphosis of the cervical spine resulted in demyelination of nerve fibers in the funiculi and neuronal loss in the anterior horn due to chronic compression of the spinal cord. These histologic changes seem to be associated with both continuous mechanical compression and vascular changes in the spinal cord.”
Treatment for Loss of Cervical Lordosis
In short, the reversed curve caused changes in the spinal cord indicative of progressive neurologic conditions. The cervical kyphosis was obtained using methods, but like any symptom of a cause, there are levels of dysfunction. The mechanical methods would hold true, although the methods used in this trial prevent duplication in humans as a result of obvious implications. It’s a fascinating area of research and one I hope continues to grow. To reiterate, the researchers showed that a cervical kyphosis (loss of cervical curve) causes changes in the spinal cord that lead to progressive neurologic degeneration. As Chiropractors, we’ve argued this for generations.
Chiropractic focuses on alignment of the spine so that the nervous system can function optimally. Research is showing a lack of adequate cervical lordosis is a element in a broad variety of conditions, some of which are severe.
If you are experiencing any of these symptoms–headache, stiff neck, neck pain, numbness, tingling, or weakness of your hands, or you’d like to get yourself or your family checked, make sure to seek help from a qualified and experienced healthcare professional to fix the cause.

Whiplash, among other automobile accident injuries, are frequently reported by victims of an auto collision, regardless of the severity and grade of the accident.

Whiplash is generally the result of an abrupt, back-and-forth jolt of the head and neck in any direction. Fortunately, a variety of treatments are available to treat automobile accident injuries.
Whiplash has been difficult to study because its pathoanatomy has remained poorly known, however, the facet joints have been recently isolated as a site of pain in many people that are whiplash-injured.
In a typical rear-end collision, the occupant’s pelvis, chest, and head are hastened forward in rapid succession. The massive inertia of the head leads to a horizontal translation (retraction) of the initially stationary head relative to the forward-accelerating torso, and this movement induces compression, shear, and ultimately tension in the cervical spine.
Recent studies have localized the chronic pain of several whiplash patients to the facet joints. Subsequent experiments involving both human subjects and cadaveric cells have demonstrated that harm to the capsular ligaments may play a part in the pathoanatomy of whiplash injury.
Kinematics of Whiplash Injuries
Biomechanical studies of whiplash injury have used human subjects, animals, cadavers, and mathematical models to investigate possible mechanisms of whiplash injury. Researcher ignorance of the tissues responsible for the pain has often limited the insights. Recent studies, however, has identified a candidate tissue for whiplash injury, and it has provided a focus for research into the mechanics of whiplash injury.
The comprehension of injury mechanics begins with an appreciation of how individuals respond to the kinds of perturbations that create whiplash injury. Rear-end collisions, where an occupant’s vehicle is struck from behind and hastened forward, have been associated with an increased risk of whiplash injury and a higher frequency of symptoms compared to other crash directions. As a result, perturbations that simulate a collision have been used by most biomechanical experiments conducted to investigate whiplash injury. Many research groups have studied subjects exposed to whiplash perturbations, and despite differences in subjects, vehicles, seats, and the crashes used with these groups, a stereotyped reaction has been observed in normally seated subjects.
The pelvis is hastened forward, due to a combination of occupant posture and seat compliance, acceleration of the torso lags behind acceleration of the pelvis. This difference in motion between the pelvis and upper torso produces a small rotation of the torso and leads to an initial flexion of the neck, despite the fact that the head is still effectively stationary at this stage in the induced kinematic response. As the torso accelerates forward relative to the head, a horizontal translation develops between the base of the head and the spine, causing the lower vertebrae of the spine to extend. The horizontal shear stiffness of the upright spine is inadequate to overcome the rotational and transitional inertia of the head, and because of this, the upper cervical segments bend. The changing configuration of the vertebrae results in the cervical spine being better able to encourage horizontal forces, and these forces both accelerate the bottom of the skull forward and establish a rearward rotation (expansion) of the head.
In the presence of a properly positioned head restraint, both the head extension angle and the horizontal translation between the torso and head (retraction) are arrested and reversed by the combination of an external force applied to the head from the head restraint and inner forces developed by both the ligamentous cervical spine and the reflex contraction of the cervical muscles.
Larger extension and retraction motions occur, and head motion could be arrested and reversed by inner ligamentous and muscle forces if no head restraint is present or if there exists a gap between the back of the head and the head restraint. The positions of the head and head restraint at effect can therefore have a substantial influence on the magnitude of the head and neck kinematics, and ultimately on the size of the loads applied to the tissues of the cervical spine.
After the interaction with the seat back and head restraint, the head and chest rebound forward. Forward torso motion could be limited by a seatbelt, whereas forward motion of the mind seems to be controlled by sustained activation of the posterior neck muscles.
