1. Neck Pain and Whiplash
Neck pain and whiplash-associated disorders (WAD) affect a
large number of individuals (approx. 12-70% in a given
year).
Recently the Bone and Joint Decade 2000-2010 Task Force on Neck Pain (Spine
2008;33[4s]suppl.15:S5-S7) released their findings on treatments for neck pain. Among the
highlights were:
Most neck pain becomes chronic and symptoms do not completely resolve; between 50
and 85% of patients will experience neck pain one to five years later;
For most patients without radicular symptoms, getting back to work and returning to
normal activities appears to improve outcomes;
Nonsurgical treatments appear to be more beneficial than usual care, sham, or alternative
interventions, but none of the active treatments were clearly superior to any other in the
short or long term. Manual therapy, mobilization, manual therapy, exercises, low-level
laser therapy, educational videos, and perhaps acupuncture appeared to be helpful;
When choosing treatments to relieve WAD grades I and II neck pain, patients and their
clinicians should consider the potential side effects and personal preferences regarding
treatment options;
There was a correlation between chiropractic care and subsequent vertebrobasilar artery
(VBAI) stroke in persons <45 years, but a similar association was seen in patients
receiving general medical practitioner treatment. This may be explained by patients with
VBAI dissection-related headache or neck pain seeking care before having their stroke.
We will take great care when adjusting your patient. There are a variety of technical procedures
for adjusting the neck.
If any neck pain patients do not respond to the first few treatments, I will let you know. Case
series of chronic whiplash patients have shown they can improve their symptoms with
chiropractic care (Injury, 1996). A marked increase in symptoms would contraindicate further
treatment with that type of manipulation.
Ask how I examine patients, and whether I feel are x-rays are needed to screen for instability or
anomalies. If your patient responds positively to treatment, this would justify continued care,
provided there is gradually less weekly frequency. Six to eight adjustments in the first two weeks
would not be unusual. This frequency would be rare for a patient in the second month of care.
The Healing of
Injured Soft Tissues

2. In this months issue we’re going to touch on area of patient treatment that has undergone
enormous leaps and bounds in our understanding over the last decade. An area I will refer to as
“Post-Traumatic Soft Tissue Injury”.
Even with recent breakthroughs in understanding the physiology of repair (and possibly because
of these RECENT breakthroughs) there is a considerable amount of misunderstanding regarding
soft tissue injury and its repair.
The most common (almost knee-jerk) misconception is that injured soft tissue will heal in a
period of time between four and eight weeks.
Frequently it is claimed that injured soft tissues will heal spontaneously, leaving no long-term
residual damage, and that treatment is not required. This type of information is extremely
misleading and confusing to both doctor and patient alike.
Published articles and books concerning the healing of injured soft tissues (Oakes 1982; Roy and
Irving 1983; Kellett 1986; Buckwalter/Woo 1988, Majno 2004) indicate that the time frame for
such healing is approximately one year.
Needless to say the difference between a recovery time of 4-8 weeks and 12 months dramatically
impacts both clinical practice and expected outcomes.
Healing Takes Place In Three Specific Phases.
Soft Tissue Healing Phase #1
Acute Inflammatory Phase.
This phase will last approximately 72 hours. During this phase, after the initial injury, an
electrical current is generated at the wound, called the “current of injury.”
This “current of injury” attracts fibroblasts to the wound (Oschman, 2000).
During this phase there is also initial bleeding and continual associated inflammation of the
injured tissues. Because of the increasing inflammatory cascade during this period of time, it is
not uncommon for the patient to feel worse for each of the first three days following injury.
Because there is disruption of local vascular supplies, there is insufficient availability of
substrate (glucose, oxygen, etc.) to produce large enough quantities of ATP energy to initiate
collagen protein synthesis to repair the wound.
After 72 hours following injury, the damaged blood vessels have mended. The resulting
increased availability of glucose and oxygen elevates local ATP levels and collagen repair begins
by the fibroblasts that accumulated during the acute inflammatory phase.
Soft Tissue Healing Phase #2
Phase Of Regeneration

3. During the regeneration phase the disruption in the injured muscles and ligaments is bridged.
Some references call the regeneration phase the phase of repair, which creates confusion about
the timing of healing (Jackson, 1977).
“Repair” connotation is that the process has completed, which, as we well see, is not the case.
The fibroblasts manufacture and secrete collagen protein glues that bridge the gap in the torn
tissues. This phase will last approximately 6-8 weeks (Jackson, 1977).
At the end of 6-8 weeks, the gap in the torn tissues is more than 90% bridged. Many will
erroneously claim this to be the end of healing. However, it clearly is not. There is a third and
final phase of healing. This phase is called the phase of remodeling
Soft Tissue Healing Phase #3
Phase Of Remodeling
The phase of remodeling starts near the end of the phase of regeneration. During the phase of
remodeling the collagen protein glues that have been laid down for repair are remodeled in the
direction of stress and strain.
This means that the fibers in the tissue will become stronger, and will change their orientation
from an irregular pattern to a more regular pattern, a pattern more like the original undamaged
tissues.
Proper treatment during this remodeling phase is very necessary if the tissues are to get the best
end product of healing. It is during this remodeling phase that the tissues regain strength and
alignment. Remodeling takes approximately one year after the date of injury.
It is established that remodeling takes place as a direct byproduct of motion. Chiropractic
healthcare puts motion into the tissues in an effort at getting them to line up along the directions
of stress and strain, thereby giving a stronger, more elastic end product of healing.
Traditional chiropractic joint manipulation healthcare is directed towards putting motion into
the periarticular paraphysiological space.
The concept of paraphysiological joint motion was first described by Sandoz in 1976, and is
explained well by Kirkalady-Willis 1983 and 1988, by Kirkalady-Willis/Cassidy 1985, and in the
2004 monograph on Neck Pain (edited by Fischgrund) published by the American Academy of
Orthopedic Surgeons (see picture).
These discussions clearly show that there is a component of motion that cannot be properly
addressed by exercise, massage, etc, and that this component of motion can be properly
addressed by osseous joint manipulation.
Therefore, traditional chiropractic osseous joint manipulation adds a unique aspect to the
treatment and the remodeling of periarticular soft tissues that have sustained an injury.

4. There are some problems associated with the healing of injured soft tissues. Microscopic
histological studies show that the repaired tissue is different than the original, adjacent,
undamaged tissues.
During the initial acute inflammatory phase there is bleeding from the damaged tissues and
consequent local inflammation. This progressive bleeding releases increased numbers of
fibroblasts into the surrounding tissues.
Chemicals that are released trigger the inflammation response that is noted in cases of trauma.
Subsequent to the inflammatory response and to the number of fibrocytes that are released into
the tissues, the healing process is really a process of fibrosis.
Fibrosis
In 1975, Stonebrink addresses that the last phase of the pathophysiological response to trauma is
tissue fibrosis. Boyd in 1953, Cyriax in 1983, and Majno/Joris in 2004 note that there is tissue
fibrosis subsequent to trauma.
This fibrosis of repair subsequent to soft tissue trauma creates problems that can adversely affect
the tissues and the patient for years, decades, or even forever.
Fibrosed tissues are functionally different from the adjacent normal tissues. The differences fall
into two main categories:
Fibrosis Category 1
The repaired tissue is weaker and less strong than the undamaged tissues. This is because the
diameter of the healing collagen fibers is smaller, and the end product of healing is deficient in
the number of crossed linkages within the collagen repair.
Fibrosis Category 2:
The repaired tissue is stiffer or less elastic than the original, undamaged tissues. This is because
the healing fibers are not aligned identically to that of the original. Examination range of motion
studies will indicate that there are areas of decrease of the normal joint ranges of motion.
In addition, Cyriax notes “fibrous tissue is capable of maintaining an inflammatory response long
after the initial cause has ceased to operate.”
Since inflammation alters the thresholds of the nociceptive afferent system, physical
examinations in these cases will show these fibrotic areas display increased sensitivity, and
digital pressure may show hypertonicity and spasm.
This increased sensitivity can be documented with the use of an algometer, which is a device that
uses pressure to determine the initiating threshold of pain.

5. Because the fibrotic residuals have rendered the tissues weaker, less elastic, and more sensitive,
the patient will have a history of flare-ups of pain and/or spasm at times of increased use or
stress.
These episodes of pain and/or spasm at times of increased use or stress of the once damaged soft
tissues is the rule rather than the exception, and a problem that the patient will have to learn to
live with.
It is likely that the patient will continue to have episodes of pain and/or spasm for an indefinite
period of time in the future. It is probable that the patient will have a need for continuing care
subsequent to these episodes of pain and/or spasm.
Consistent with these concepts, a study by Hodgson in 1989 indicated that…
62% of those injured in automobile accidents still have significant symptoms caused by the
accident 12 1/2 years after being injured; and that of the symptomatic 62%, 62.5% had to
permanently alter their work activities and 44% had to permanently alter their leisure
activities in order to avoid exacerbation of symptoms.
One of the conclusions of the article is that these long-term residuals were most likely the result
of post-traumatic alterations in the once damaged tissues.
A study by Gargan in 1990 indicated that…
Only 12% of those sustaining a soft tissue neck injury had achieved a complete recovery
more than ten years after the date of the accident.
One of the conclusions of this study is that the patient's symptoms would not improve after a
period of two years following the injury.
It is established neurologically (Wyke 1985, Kirkalady-Willis and Cassidy 1985) that when a
chiropractor adjusts (specific directional spinal manipulation) the joints of the region of pain
and/or spasm, that there is a depolarization of the mechanoreceptors that are located in the facet
joint capsular ligaments, and that the cycle of pain and/or spasm can be neurologically aborted.
This is why many patients feel better after they receive specific joint manipulation from a
chiropractor following an episode of increased pain and/or spasm.
What Is The Basis For The
Chronic Post-Trauma Pain Syndromes
So Many Patients Suffer From?
A good explanation is found from Gunn (1978, 1980, 1989). He refers to this type of pain as
supersensitivity.
The supersensitivity type pain is a residual of the scarring or the fibrosis that was created by the
injuries sustained in this accident.

6. The treatment that we give to the patient for the injuries sustained in an accident is really not
designed to heal the sprain or strain but rather, to change the fibrotic nature of the reparative
process that has left the patient with residuals that are weaker, stiffer, and more sore.
The actual diagnosis for this type of problem is initial sprain/strain injuries of the paraspinal soft
tissues with fibrotic residuals subsequent to the fibrosis of repair of once damaged soft tissues
that have left these tissues weaker, stiffer, and more sensitive as compared to the original tissues.
The majority of our efforts in the treatment of post-traumatic chronic pain syndrome patients is
in dealing with the residual fibrosis of repair and its associated mechanical and neurological
consequences.
These residuals to some degree are most probably permanent. The patient will have to learn to
deal with the long-term residuals and the occasional episodes of pain and/or spasm.
However, as noted above, occasional specific joint manipulation in the involved areas can
neurologically inhibit muscle tone, improve ranges of motion, disperse accumulated
inflammatory exudates, and the patient will have less pain and improved function.
The concepts briefly discussed above are frequently not understood or appreciated. There is a
tendency for healthcare providers to not properly examine the patient in order to document these
regions of tissue fibrosis and its consequent mechanical and neurological consequences and,
therefore, to quote Stonebrink, the real problem is missed.
