A large number of factors have been identified as causes of trigger point activation. These include acute or chronic overload of muscle tissue, disease, psychological distress, systemic inflammation, homeostatic imbalances, direct trauma, radiculopathy, infections, and lifestyle choices such as smoking. Trigger points form as a local contraction of muscle fibres in a muscle or bundle of muscle fibres. These can pull on ligaments and tendons associated with the muscle which can cause pain to be felt deep inside a joint. It is theorized that trigger points form from excessive release of acetylcholine causing sustained depolarization of muscle fibres. Trigger points present an abnormal biochemical composition with elevated levels of acetylcholine, noradrenaline and serotonin and a lower ph. The contracted fibres in a trigger point constricts blood supply to the area creating an energy crisis in the tissue that results in the production of sensitizing substances that interact with pain receptors producing pain. When trigger points are present in a muscle there is often pain and weakness in the associated structures. These pain patterns follow specific nerve pathways that have been well mapped to allow for accurate diagnosis or the causative pain factor.
Headache
Upper Crossed Syndrome/Desk Neck
Your posture plays an important role in your overall health. Poor posture leads to chronic strain and discomfort. “Upper crossed syndrome” describes poor posture that results from excessive tightness in your shoulders and chest with weakness in your neck and mid-back. This combination forces your shoulders to roll inward and your head to project forward.
To help understand how upper crossed syndrome causes trouble, think of your spine as a telephone pole and your head as a bowling ball that sits on top. When the bowling ball is positioned directly over the top of the upright post, very little effort is required to keep it in place. If you tip the post forward and the ball begins to roll over the edge of the post, significantly more effort would be required from the muscles trying to hold it there. This effort results in chronic strain of the muscles of your neck and upper back.
The chronic strain is uncomfortable and may also lead to neck pain, upper back pain, headaches, TMJ pain, and ultimately- arthritis. This postural problem is exceptionally common in computer workstation users.
Correction of this problem is accomplished by stretching the tight muscles, strengthening weak muscles, and modifying your workstation. Treatment is aimed at reducing and eliminating symptoms through the use of Chiropractic adjustments, soft tissue release, acupuncture and trigger point therapy.
Diagnosis of trigger points.
Diagnosis of trigger points typically takes into account symptoms, pain patterns, and manual palpation. When palpating the therapist will feel for a taut band of muscle with a hard nodule within it. Often a local twitch response will be elicited by running a finger perpendicular to the muscle fibres direction. Pressure applied to the trigger point will often reproduce the pain complaint of the patient and the referral pattern of the trigger point. Often there is a heat differential in the local area of the trigger point. 
What is a trigger point
Dr Janet travel coined the term trigger point in 1942 to describe clinical findings with characteristics of pain related a discrete irritable point in muscle or fascia that was not caused by acute trauma, inflammation, degeneration, neoplasm or infection. The painful point can be palpated as a nodule or tight band in the muscle that can produce a local twitch response when stimulated. Palpation of the trigger point reproduces the pain and symptoms of the patient and the pain radiates in a predictable referral pattern specific to the muscle harbouring the trigger point.
What to expect with a trigger point massage.
A treatment with Bryan is very user friendly. And, no, you don’t have to remove any clothing. However, bringing a t-shirt and a pair of shorts or sweats is recommended.
The first time you come for a treatment you will be asked to fill out a Client History form. Bryan will go over the information you provide, asking for more detail and discussing the type of pain you are having and its location.
The treatment itself involves locating the Trigger Points in the muscle or soft tissue and applying a deep focused pressure to the Point. This will reproduce the pain and the referral pattern that is characteristic of that pain.
The treatment will be uncomfortable at first, but as the Trigger Points release, the pain will decrease. The pressure will always be adjusted to your tolerance level. If, at any time, you feel too uncomfortable you can ask Bryan to ease off a bit.
Depending on your specific problem, Bryan may also use some stretching and / or range-of-motion techniques, as needed.
After treatment, it is usually recommended that the client apply moist heat to the area treated.

You may have heard the comment, “If there’s no damage to the car, then there’s no injury.” Unfortunately, that does not always seem to be the case.
There are MANY factors that affect the dynamics of a collision and whether or not injury occurs. A short list includes: vehicle type and design, speed, angle of collision, momentum, acceleration factors, friction, kinetic and potential energy, height, weight, muscle mass, seat back angle and spring, head position upon impact, etc.
Consider Sir Isaac Newton’s Third Law of Motion: “For every action there is an equal and opposite reaction.” This law applies to a car accident at any speed. Using the analogy of hitting a pool ball into the corner pocket straight on, when the cue ball stops, its momentum is transferred to the target ball which accelerates at the same speed…hopefully into the corner pocket!
This example is not quite the same as an automobile collision because the energy transfer is very efficient due in part to the two pool balls not deforming (crushing or breaking) on impact with one another. If either ball did deform, more energy absorption would occur and the acceleration of the second ball would be lower.
In fact, in the United States, vehicle bumpers are tested at 2.5 mph with impact equipment of similar mass with the test vehicle’s brakes disengaged and the transmission in neutral. National Highway Transportation Highway Safety Administration (NHTSA) vehicle safety standards demand that no damage should occur to the car in this scenario.
However, energy transfer occurs very quickly and with a greater amount of force when there is no vehicle deformation (damage). As a result, a greater amount of energy (described as G-force) is directly transferred to the occupants inside the vehicle—increasing the risk of injury. A 1997 Society of Automobile Engineers article provided an example in which the same 25 mph (12 m/s) collision resulted in a five-times greater force on the occupants of the vehicle when the crush distance of the impact fell from 1 meter to .2 meters.
So be aware that even low-speed impacts can still place quite a bit of force on your body, even if the bumper of your car doesn’t have a scratch on it.
What is a Migraine? What can I do about them?
A “migraine” is an intense throbbing headache that may be accompanied by nausea, vomiting, and sensitivity to light or noise. Adult women are three times more likely than men to experience migraines. The frequency of migraine headaches usually peaks between age 30 and 40, and attacks decrease thereafter. The onset of a new migraine headache after age 50 is rare.
Migraine headaches are caused by a combination of nerve irritation and enlargement of the blood vessels in your brain. Migraines tend to run in families and sufferers have inherited a sensitive nervous system from their parents. Patients who are overweight or have other vascular risk factors are more likely to suffer from migraines.
Migraines are set off by “triggers” and the headache occurs when the number of triggers reaches a critical threshold. This can be likened to a glass of water that overflows at a certain point. Known triggers include: neck tightness, stress, smoking, strong odors (i.e. perfumes), bright or flickering lights, fluorescent lighting, too little or much sleep, head trauma, weather changes, motion sickness, cold (ice cream headaches), lack of activity or exercise, overexertion, fatigue, eyestrain, dehydration, hunger, fasting, and hormonal changes, including menstruation and ovulation. Certain medications, including hormones or oral contraceptives are known triggers. A detailed list of foods that trigger migraines is provided below.
About 20-33% of people who get migraines have warning symptoms, called an “aura”, before their actual headache attack. Aura symptoms develop slowly over five to 20 minutes and can last up to an hour. The most common aura is a band of absent vision with an irregular shimmering border. Some patients report numbness or tingling in their arms or face. Be sure to tell your doctor if you experience any confusion or decreased consciousness with your headache. Other signs to watch for include: abrupt headaches that develop and peak very quickly, headaches that develop following a head injury, light-headedness, dizziness, difficulty speaking, difficulty swallowing, difficulty walking, fever, rash, or any “new” headache that is significantly different from your prior headaches.
Many patients benefit from the types of treatment provided in this office. Research has shown a “significant reduction” in migraine frequency and intensity through chiropractic care. Your home management will focus on avoiding “triggers” and stress. You should begin keeping a headache diary to help you track and eliminate triggers. Patients who experience migraines are more susceptible to other types of cardiovascular disease, like heart attack and stroke. Be sure to choose a “heart healthy” diet (i.e. limit sodium and fats) and keep your weight controlled. Eat at regular intervals and stay well-hydrated as hunger and dehydration are known triggers.
Your doctor may talk to you about supplements like Feverfew (125mg/ day), Riboflavin (400mg/ day), Magnesium (400-600mg/ day) and Co-enzyme Q10 (100mg 3x per day) that have been helpful in preventing headaches for some migraine sufferers. The American Headache Society recommends that patients avoid overuse of medication to control their headaches, (no more than 2 doses per day, 2 days/week) as this can lead to more frequent “rebound” headaches. Do not begin or discontinue any new vitamins or medications without talking to your doctor first, especially if you are nursing or pregnant.
What evidence do we have of whiplash?
Whiplash, or WAD (Whiplash Associated Disorders), refers to a neck injury where the normal range of motion is exceeded, resulting in injury to the soft-tissues (hopefully with no fractures) in the cervical region. There are a LOT of factors involved that enter into the degree of injury and length of healing time. Let’s take a closer look!
Picture the classic rear-end collision. The incident itself may be over within 300 milliseconds (msec), which is why it’s virtually impossible to brace yourself effectively for the crash as a typical voluntary muscle contraction takes two to three times longer (800-1000 msec) to accomplish.
In the first 50 msec, the force of the rear-end collision pushes the vehicle (and the torso of the body) forwards leaving the head behind so the cervical spine straightens out from its normal “C-shape” (or lordosis). By 75-100 msec, the lower part of the neck extends or becomes more C-shaped while the upper half flexes or moves in an opposite direction creating an “S” shape to the neck. Between 150-200msec, the whole neck hyper extends and the head may hit the head rest IF the headrest is positioned properly. In the last 200-300 msec, the head is propelled forwards into flexion in a “crack the whip” type of motion.
Injury to the neck may occur at various stages of this very fast process, and many factors determine the degree of injury such as a smaller car being hit by a larger car, the impact direction, the position of the head upon impact (worse if turned), if the neck is tall and slender vs. short and muscular, the angle and “springiness” of the seat back and relative position of the headrest, dry vs. wet/slippery pavement, and airbag deployment, just to name a few.
Some other factors that can predict recovery include: limited neck motion, the presence of neurological loss (nerve specific muscle weakness and/or numbness/tingling), high initial pain levels (>5/10 on a 0-10 scale), high disability scores on questionnaires, overly fearful of harming oneself with usual activity and/or work, depressive symptoms, post-traumatic stress, poor coping skills, headaches, back pain, widespread or whole body pain, dizziness, negative expectation of recovery, pending litigation, catastrophizing, age (older is worse), and poor pre-collision health (both mental and physical).
Research shows the best outcomes occur when patients are assured that most people fully recover and when patients stay active and working as much as possible. Studies have shown it’s best to avoid prolonged inactivity and cervical collars unless under a doctor’s orders. It’s also a good idea to gradually introduce exercises aimed at improving range of motion, postural endurance, and motor control provided doing so keeps the patient within reasonable pain boundaries. Chiropractic manipulation restores movement in fixed or stuck joints in the back and neck and has been found to help significantly with neck pain and headaches, particularly for patients involved in motor vehicle collisions. A doctor of chiropractic may also recommend using a cervical pillow, home traction, massage, and other therapies as part of the recovery process.
It is important to be aware that fear of normal activity and not engaging in usual activities and work can delay healing and promote chronic problems and long-term disability. It’s suggested patients avoid opioid medication use due to the addictive problems with such drugs. Ice and anti-inflammatory herbs or nutrients (like ginger, turmeric, and bioflavonoids) are safer options. Your doctor of chiropractic can guide you in this process!
How can I calm down my WAD symptoms?
Whiplash is really a slang term for the rapid back and forth whipping of the head on the neck, usually associated with motor vehicle accidents. The title “Whiplash Associated Disorders”, or WAD, describes it best because it includes ALL of the MANY signs and symptoms of the disorder.
WAD basically comes in three sizes based on the degree of injury. A WAD I is present when there is pain but no physical examination findings; WAD II occurs when there are exam findings but no neurological loss (numbness or weakness); and WAD III includes loss of neurological function. There is also a separate WAD level that includes fractures and dislocations (WAD IV).
There are many things that can be done by the patient to assist in the healing process for WAD. The first well-studied recommendation is to “continue with your usual activities.” Try to keep active and not change your routine. The good news is that WAD (especially types I and II) usually resolves without complication, and recovery is even more likely to occur if you don’t deviate much from your routine.
For those whose symptoms are more severe and/or not resolving, mobilization and manipulation of the neck and back are very effective treatment options. In addition to treatments you’d receive in a chiropractic office, there are MANY things you can do at home as “self-help strategies.” Some of these include (“PRICE”):
1) PROTECT: Though it’s important to continue with your usual daily activities, this is dependent on both the degree of tissue injury and your pain tolerance. So do as many of your usual daily activities as possible, but AVOID those that result in a sharp, lancinating type of pain or those where recovery from the pain is delayed. Therefore, this category may require modifying your ADLs (activities of daily living). A cervical collar (hard orsoft) should NOT to be used UNLESS you have an unstable injury (fracture or a grade III sprain).
2) REST: Doing too much is like picking at a cut (which can delay healing) and doing too little can lead to a delayed healing response as well. Staying within reasonable pain boundaries is a good guide.
3) ICE > HEAT: Ice reduces swelling, and your doctor will typically recommend it over applying heat, especially on a recent injury. Heat draws fluids in, and while it may feel good, it can make your symptoms worse.
4) COMPRESS: We can basically ignore this when referencing neck pain. This pertains better to wrapping an ankle, knee, wrist, or elbow with an elastic compression orthotic or brace.
5) ELEVATE: This too is meant for the acute stages of an extremity injury like a foot or ankle.
Exercises unique for neck pain in the acute, subacute, and chronic stages of healing are perhaps the most important of the self-help approaches. In the ACUTE phase, try these…
1) Range of Motion: Once again, stay within “reasonable pain boundaries” as you move your head forwards, backwards, side to side, and rotate left and right. These can be done either with or without LIGHT resistance applied using one or two fingers placed against your head. Limit the repetitions to three slow reps in each direction and emphasize the release of the movement.
2) Chin/head Glides: Tuck in the chin (think of creating a double or triple chin) followed by poking the chin/head out.
In the SUBACUTE and CHRONIC phases of healing, the importance of strengthening the deep neck flexors cannot be over emphasized. Please refer to last week’s article for a description of this (see #3 of the 6 recommendations listed).
Trigger points in the trapezius muscle.
The trapezius muscle is a large diamond shaped muscle in you mid/upper back and neck. This muscle is one of the most common sites where trigger points can form. This muscle originates on the Nuchal ligament and the spinous processes of C6-T12. It inserts on the spine of the scapula, the acromion process, and the distal clavicle. The upper fibres elevate the shoulder and rotate the glenoid fossa (shoulder socket) upward. The lower fibres assist this motion as well as help depress the shoulder. The middle fibres of this muscle strongly adduct the scapula. This muscle is susceptible to postural overload such as sitting at desk all day. Trigger points on the lateral upper edge refer into the lateral neck and temples, causing “tension neck ache”as well as headache pain.Trigger points in the middle and lower fibres refer pain into the posterior neck and shoulder.
