Trigger points in the masseter muscle

~ bryancobb ~ Leave a comment

The masseter is the main muscle that moves your jaw. It originates on the zygomatic arch and maxilla, and inserts on the coronoid process and Ramus of the mandible. It’s actions are to elevate the mandible and close the jaw. The deep fibres of this muscle also retrude the mandible. This muscle commonly harbours trigger points as a result of teeth grinding. Trigger points in this muscle are often also associated with tmj dysfunction. Trigger points in the upper part of this muscle will refer pain to the upper molars and maxilla often felt as sinusitis. Trigger points in the lower portion of this muscle refer to the lower molars and temple. All trigger points can cause tooth sensitivity

So I’ve got Whiplash; now what?

​Whiplash, or “Whiplash Associated Disorders” or WAD, is the result of a sudden “crack the whip” of the head on the neck due to a slip and fall, sports injury, a violent act, or most commonly, a motor vehicle collision (MVC), particularly a rear-end collision. In describing “what can I expect” after a whiplash injury, one thing is for certain, there are many faces of whiplash, meaning the degree of injury can range from none to catastrophic depending on many factors, some of which are difficult or impossible to identify or calculate. Let’s take a closer look!

Even though the good news is that most people injured in a car crash get better, 10% do not and go on to have chronic pain, of which about half have significant difficulty working and/or doing desired everyday activities. There is a “great debate” as to the way experts describe “chronic whiplash syndrome” (CWS) as well as how these cases should be managed. Some feel there is something PHYSICALLY wrong in the CWS patient, especially if severe neck or head pain persists for more than one year. There is some proof of this as Dr. Nikolai Bogduk from the University of Newcastle in Australia and colleagues have used selective nerve blocks to anesthetize specific joints in the neck to determine exactly where the pain is generated. The patient then has the option to have that nerve cauterized or burned and pain relief can be significant in many cases. Dr. Bogduk and his group admit that these CWS patients have more psychological symptoms, but they feel this is the result of pain, not the CAUSE.

On the other hand, experts such as Dr. Henry Berry from the University of Toronto report the EXACT OPPOSITE. He argues that it’s not JUST the physical injury that has to be dealt with but also the person’s “state of mind.” Dr. Berry states that when stepping back and looking at all the complaints or symptoms from a distance, “…you see these symptoms can be caused by life stress, the illness ‘role’ as a way of adjusting to life, psychiatric disorders, or even [made up by the patient].” Berry contends that it’s important to tell the patient their pain will go away soon, advises NO MORE THAN two weeks of physical therapy, and sends people back to work ASAP.

Oregon Health Sciences University School of Medicine’s Dr. Michael D. Freeman, whose expertise lay in epidemiology and forensic science, disagrees with Dr. Berry stating that the scientific literature clearly supports the physical injury concept and states, “…the idea that it is a psychological disturbance is a myth that has been perpetuated with absolutely no scientific basis at all.” Dr. Freeman states that 45% of people with chronic neck pain were injured in a motor vehicle crash (which includes three million of the six million of those injured in car crashes every year in the United States).

Here’s the “take home” to consider: 1) CWS occurs in about 10% of rear-end collisions; 2) Some doctors feel the pain is physically generated from specific nerves inside the neck joints; 3) Others argue it’s a combination of psychological factors and care should focus on preventing sufferers from becoming chronic patients.

Many studies report that chiropractic offers fast, cost-effective benefits for whiplash-injured patients with faster return to work times and higher levels of patient satisfaction.

Trigger points in the suboccipitals.

The suboccipitals are a group or four muscles that attach to the transverse and spinous process of C1 and C2 and the occipital bone.

These muscles provide extension side bending and rotation movements between the occiput and C1 and C2. These muscles are often overloaded due to postural strain. A classic example being sitting in front of a computer all day.

When these muscles are overloaded trigger points can develop. Pain and symptoms of trigger points in the suboccipitals include head pain that penetrates into the skull but is difficult to localize.

Patients are likely to describe the pain as “all over” including the occiput, eye and forehead, but without any clarity. Trigger points in these muscles are often associated with tension head aches

Brain injury after whiplash?

Cerebellum​

In a 2010 study, researchers examined MRIs taken from 1,200 patients (600 whiplash and 600 non-whiplash neck pain patients) and noted that those who had sustained whiplash were more likely to have a brain injury than non-whiplash neck pain patients.

The specific type of brain injury found is a form of herniation called Chiari malformation, where the bottom part of the brain (the cerebellum) drops through the opening in the base of the skull called the foramen magnum. Their findings showed an alarming 23% of the whiplash cases studied had this anatomical abnormality.

Dr. Michael Freeman, Dr. Ezriel Kormel, and colleagues collaborated in this effort and evaluated the patients using MRI in both recumbent (laying down) AND upright positions. Interestingly, they found 5.7% and 5.3% of those in the non-whiplash neck pain group and 9.8% and 23.3% in the whiplash group had the Chiari malformation using the recumbent vs. upright MRI positions, respectfully.

Dr. Kormel stated, “This condition can be quite painful and endanger the patient’s health, with symptoms that may include headaches, neck pain, upper extremity numbness and tingling, and weakness. In a few cases, there can also be lower extremity weakness and brain dysfunction.” In a radio interview, he added the advice that ANYONE suffering from whiplash should see a healthcare provider immediately.

This study is important for a number of reasons. First, it revealed that there is often a more serious injury when whiplash occurs than what is initially found. Second, psychological findings like depression, anxiety, and difficulty coping with the decreased ability or inability to be productive at home or work may suggest the presence of an anatomical injury which simply has not yet been found. Third, MRI is frequently ONLY performed in a laying down position. This study didn’t find much difference between laying vs. weight-bearing MRI positions in the non-whiplash neck pain patients but not so in the whiplash neck pain group! In this group, the ability for MRI to detect Chiari malformation/brain injury more than doubled using weight-bearing MRI.

Expanding the last point, since one out of five whiplash patients had a brain injury that is more likely to be detected using a non-traditional upright MRI position, a “new” standard” for the use of MRI in the evaluation of the whiplash patient should be considered. This is especially important in those cases that are non-responsive to quality care or if their doctor had only ordered a recumbent MRI previously.

Doctors of all disciplines should be aware of this study and the need for a more thorough evaluation, especially when a whiplash patient is not responding as one might expect.

Chiro & Concussions

​Whiplash Associated Disorders (WAD) is the appropriate terminology to use when addressing the myriad of symptoms that can occur as a result of a motor vehicle collision (MVC). In a recent publication in The Physician and Sports Medicine (Volume 43, Issue 3, 2015; 7/3/15 online:1-11), the article “The role of the cervical spine in post-concussive syndrome” takes a look at the neck when it’s injured in a car accident and how this relates to concussion.

It’s estimated about 3.8 million concussion injuries, also referred to as “mild traumatic brain injury” (mTBI), occur each year in the United States. Ironically, it’s one of the least understood injuries in the sports medicine and neuroscience communities. The GOOD NEWS is that concussion symptoms resolve within 7-10 days in the majority of cases; unfortunately, this isn’t the case with 10-15% of patients. Symptoms can last weeks, months, or even years in this group for which the term “post-concussive syndrome” (PCS) is used (defined as three or more symptoms lasting for four weeks as defined by the ICD-10) or three months following a minor head injury (as defined by the Diagnostic and Statistical Manual of Mental Disorders).

There have been significant advances in understanding what takes place in the acute phase of mTBI, but unfortunately, there is no clear physiological explanation for the chronic phase. Studies show the range of force to the head needed to cause concussion is between 60-160g (“g” = gravity) with 96.1g representing the highest predictive value in a football injury, whereas as little as 4.5g of neck acceleration can cause mild strain injury to the neck. In spite of this difference, the signs and symptoms reported by those injured in low-speed MVCs vs. football collisions are strikingly similar!

Research shows if an individual sustains an injury where the head is accelerated between 60-160g, it is HIGHLY likely that the tissues of the cervical spine (neck) have also reached their injury threshold of 4.5g. In a study that looked at hockey players, those who sustained a concussion also had WAD / neck injuries indicating that these injuries occur concurrently. Injuries to the neck in WAD include the same symptoms that occur in concussion including headache, dizziness/balance loss, nausea, visual and auditory problems, and cognitive dysfunction, just to name a few.

The paper concludes with five cases of PCS that responded well to a combination of active exercise/rehabilitation AND passive manual therapy (cervical spine manipulation). The favourable outcome supports the concept that the neck injury portion of WAD is a very important aspect to consider when treating patients with PCS!

This “link” between neck injury and concussion explains why chiropractic care is essential in the treatment of the concussion patient! This is especially true when the symptoms of concussion persist longer than one month!
