Resolving Whiplash Injuries with Active Release – Part 6

Research has shown that individuals with abnormal neurological signs, such as those seen with peripheral nerve compression syndromes (entrapment neuropathies), are more likely to develop chronic neck problems.

The nerve compression associated with a whiplash injury can cause several physiological changes to peripheral nerves especially if this compression is left untreated for a long period of time.

Symptoms of a nerve entrapment syndrome

Peripheral nerve entrapment syndromes usually involve both motor and sensory nerves. Entrapment of sensory nerves creates pain and paresthesia. Paresthesia is a sensation of tingling, pricking, increased sensitivity, or numbness. Motor nerves allow the brain to stimulate muscle contraction. Entrapment of motor nerves causes weakness, decreases muscle function, and muscle atrophy (wasting away).

The exact symptoms of nerve entrapment will vary depending on the location of the nerve entrapment. If a patient has these symptoms they should be closely monitored and treated as soon as possible.

Treating Nerve Compression Syndromes

Usually, addressing nerve compression syndromes can be a difficult problem to deal with. Considering the potential problems, such as myelin sheath damage, that can occur if these syndromes are not treated soon enough, early intervention become critical.

Fortunately there are specific protocols that ART practitioners can use to release these entrapments. It is important to note that nerve compression that occurs during a traumatic incident such as a whiplash accident can affect a nerve anywhere along its path. The following list shows examples of common whiplash symptoms, entrapment sites, and the nerves that can be released with the appropriate ART procedure.

The following are only a few examples of symptoms and nerve entrapment sites that ART procedures can address.

Symptom - Neck Pain

• Site of entrapment SCM Muscle – Nerve involved Spinal accessory nerve

Symptom - Headaches

• Site of entrapment Semispinalis Capitis Muscle - Nerve involved Greater occipital nerve

Symptom - Shoulder pain

• Site of entrapment Quadrangular Space – Nerve involved Axillary nerve

Symptom - Arm pain

• Site of entrapment Pronator Teres Muscle – Nerve involved Median Nerve

See Part 7 (The last of this series) – Resolving Whiplash Injuries with Active Release will cover treatment and exercises.

Resolving Whiplash Injuries with Active Release – Part 5

Take Care of the Entire Kinetic Chain

Although early intervention is important, it is equally important to have the the practitioner consider all the areas that could be, or are, damaged in a hyper-extension, hyper-flexion injury. The practitioner must look for damage in more than just the neck, and review possible injuries to the patient’s jaw, shoulders, arms, wrists, upper-back, lower-back, hips, and some times even the lower extremities. Areas that have been injured often do not show symptoms for several weeks.

This is often the case with jaw problems caused by whiplash injuries. With whiplash injuries, one in three people who have been in a hyper-extension hyper-flexion accident will develop delayed TMJ problems.

Delayed temporomandibular joint pain and dysfunction induced by whiplash trauma: a controlled prospective study Journal of the American Dental Association August 2007;138(8):pp. 1084-91 Salé H, Isberg A.

From a kinetic chain perspective, jaw motion and neck motion are directly linked to each other. Activation of neck and jaw muscles occurs simultaneously, which synchronized movements of the TMJ, cervical spine, and the atlanto-occipital joints. (The Atlanto-occipital joint lies between the base of the skull (occiput) and the C1 vertebra (atlas)).

Deranged jaw–neck motor control in whiplash-associated disorders European Journal of Oral Sciences, February, 2004; 112: 25–32. Per-Olof Eriksson, Hamayun Zafar, Birgitta Haggman-Henrikson

Thus any injury to neck muscles can directly affect jaw function. When Active Release practitioners consider this type of kinetic chain relationship, it becomes much easier to resolve whiplash injuries. Which leads me to an important point, you need to find an ART practitioner who is certified in biomechanics, as that could make a huge difference in resolving your condition. Practitioners with a strong biomechanics training will have a better understanding of kinetic chain relationships can more easily identify structures that are involved in the injury.

Resolving Whiplash Injuries with Active Release – Part 3

Hyper-Flexion Phase

Next, the car seat springs forward causing the driver’s whole torso to move forward at a high velocity. Physics defines velocity as “rapidity or speed of motion; swiftness.” Keep in mind as your seat moves forward your head is still moving back. This action is similar to the final moment before a spring releases.

Then, almost instantaneously your torso and head are flung forward. This forward motion is so strong that if the driver does not have their seat belt on they could, depending on force of impact, be thrown right out of their seat into the steering wheel or even through the window. This strong forward action causes the driver’s whole spine to flex forward often past their physiological limits. This action can cause a considerable amount of posterior neck, mid-back, shoulder, and even low back damage.

Common areas of damage as the head is thrown forward:

Joints

o Facet joints - These joints are the most commonly injured joints in the neck.

Posterior Ligaments

o Supraspinous ligament - strong fibrous cord, which connects together the spinous processes.

Posterior Muscles and Nerves

o Erector spinae muscles (Iliocostalis, Longissimus, Spinalis).

· Group of back muscles that runs beside the vertebrae in an almost vertical direction.

· These neck extensors are commonly injured during whiplash accidents.

o Rectus Capitis Posterior Minor muscle

· Individuals with chronic neck pain exhibit muscle atrophy of this muscle as seen of MRI. This can be caused by trauma or compression of the first cervical branches of the spinal nerves (C1 dorsal ramus). This compression occurs because of entrapment within the rectus capitis posterior major muscle.

· Atrophy of this muscle and C1 injury causes symptoms such as: suboccipital headaches with radiation of pain behind the eyes, dizziness, and benign positional vertigo (BPV). With BPV you will feel a sudden sensation of movement, or spinning, when you move your head or hold it in certain positions.

NEUROGENIC ATROPHY OF SUBOCCIPITAL MUSCLES AFTER A CERVICAL INJURY: A Case Study American Journal of Physical Medicine & Rehabilitation, Volume 77(6) November/December 1998, pp 545-549 Andary, Michael T. MD; Hallgren, Richard C. PhD; Greenman, Philip E. DO; Rechtien, James J. DO, PhD

o Suboccipital Triangle – This is an area in the neck at the base of the skull surrounded by the following three muscles

· Rectus Capitis Posterior major

· Superior and Inferior obliques

o All of the suboccipital muscles are extremely important as they contain very high levels of muscle spindle fibers. Muscle spindles provide postural information to the central nervous system. Damage to these structure in experimental animals cause gait disturbances and ataxia (an inability to coordinate voluntary muscle movements)

o The Suboccipital nerve supplies input to the muscles of the suboccipital triangle. Compression of this nerve can occur at the superior oblique muscle.

o Semispinalis (Capitis, Cervicis)

· The greater occipital nerve is located directly under the Semispinalis Capitis. Compression of this nerve is one of the causes of cervicogenic headaches, these are referred to as occipital neuralgias.

§ Occipital neuralgia is a medical condition characterized by chronic pain in the upper neck, back of the head, and behind the eyes. This is sometimes known as C2 neuralgia or Arnold’s neuralgia.

§ Research has shown that about 85% of patients with whiplash injuries have trigger points in the Semispinalis Capitis muscle.

A Distinct Pattern of Myofascial Findings in Patients After Whiplash Injury Archives of Physical Medicine and Rehabilitation Volume 89, Issue 7, July 2008, Pages 1290-1293

o Splenius (capitis, cervicis)

· This neck extensor is commonly injured in whiplash injuries.

Luo Z, Goldsmith W. Reaction of a human head/neck/torso system to shock. Journal of Biomechanics 1991;24(7):499-510

o Transversospinalis (spinalis cervicis, cervical multifidus, rotatores cervical)

· The spinalis cervicis muscle is not present in everyone (inconsistent muscle). Orginates from a ligament in the lower neck (ligamentum nuchae).

· The is some research showing the cervical multifidus msucle can cause increased loading of the joint capsule surrounding the joint in the neck (collision-induced loading of facet capsular ligaments).

· These deep posterior muscles are often injured during whiplash accidents.

Are cervical multifidus muscles active during whiplash and startle? An initial experimental study Gunter P Siegmund, Jean-Sébastien Blouin, Mark G Carpenter, John R Brault, and J Timothy Inglis BMC Musculoskelet Disord. 2008; 9: 80. Published online 2008 June 5. doi: 10.1186/1471-2474-9-80

o Trapezius (upper fibers)

· The third occipital nerve travels under the trapezius muscle until it pierces this muscle and ends up in the lower part of the head (occiput). Compression of this nerve causes occipital neuralgias.
