Whiplash and Your Posture

WRD 2.gif

Posture assessment is a key component of the chiropractic examination, and the posture of the head and neck is especially important for a patient recovering from a whiplash injury. Forward head carriage describes a state in which the head sits more forward on the shoulders than it should. In order for the muscles in the neck and shoulders to keep the head upright, they must work harder. This added strain can increase one’s risk for neck pain and headaches, which is why retraining posture is a key component to the management of neck pain and headaches in patients with or without a history of whiplash.

Forward head carriage also increases the distance between the back of the head and the headrest in the seated position, especially when the seat is reclined. In a rear-end collision, a gap greater than a half an inch between the head rest and the back of the head increases the probability of injury due to the greater distance the head can hyperextend as it rebounds backwards into the headrest.  This makes posture correction of forward head carriage an important aspect of treatment from both a preventative and curative perspective.

So this begs the question, can forward head carriage be corrected?  The simple answer is “yes!” One study evaluated the effects of a 16-week resistance and stretching program designed to address forward head posture and protracted shoulder positioning.

Researchers conducted the study in two separate secondary schools with 130 adolescents aged 15–17 years with forward head and protracted shoulder posture. The control group participated in a regular physical education (PE) program while the experimental group attended the same PE classes with the addition of specific exercises for posture correction. The research ream measured the teens’ shoulder head posture from the side using two different validated methods and tracked symptoms using a questionnaire. The results revealed a significant improvement in the shoulder and cervical angle in the experimental group that did not occur in the control group.

The conclusion of the study strongly supports that a 16-week resistance and stretching program is effective in decreasing forward head and protracted shoulder posture in adolescents.  This would suggest that a program such as this should be strongly considered in the regular curriculum of PE courses since this is such a common problem.

Doctors of chiropractic are trained to evaluate and manage forward head posture with shoulder protraction. This can prove beneficial in both the prevention as well as management of signs and symptoms associated with a whiplash injury.

Do I have a tension headache? Or Migranes?

Cervicogenic

Most likely, everyone reading this article has had a headache at one time or another. The American Headache Society reports that nearly 40% of the population suffers from episodic headaches each year while 3% have chronic tension-type headaches. The United States Department of Health and Human Services estimates that 29.5 million Americans experience migraines, but tension headaches are more common than migraines at a frequency of 5 to 1. Knowing the difference between the two is important, as the proper diagnosis can guide treatment in the right direction.

TENSION HEADACHES: These typically result in a steady ache and tightness located in the neck, particularly at the base of the skull, which can irritate the upper cervical nerve roots resulting in radiating pain and/or numbness into the head. At times, the pain can reach the eyes but often stops at the top of the head. Common triggers include stress, muscle strain, or anxiety.

MIGRAINE HEADACHES: Migraines are often much more intense, severe, and sometimes incapacitating. They usually remain on one side of the head and are associated with nausea and/or vomiting. An “aura”, or a pre-headache warning, often comes with symptoms such as a bright flashing light, ringing or noise in the ears, a visual floater, and more. For migraine headaches, there is often a strong family history, which indicates genetics may play a role in their origin.

There are many causes for headaches. Commonly, they include lack of sleep and/or stress and they can also result from a recent injury—such as a car accident, and/or a sports injury—especially when accompanied by a concussion.

Certain things can “trigger” a migraine including caffeine, chocolate, citrus fruits, cured meats, dehydration, depression, diet (skipping meals), dried fish, dried fruit, exercise (excessive), eyestrain, fatigue (extreme), food additives (nitrites, nitrates, MSG), lights (bright, flickering, glare), menstruation, some medications, noise, nuts, odors, onions, altered sleep, stress, watching TV, red wine/alcohol, weather, etc.

Posture is also a very important consideration. A forward head carriage is not only related to headaches, but also neck and back pain. We’ve previously pointed out that every inch (2.54 cm) the average 12 pound head (5.44 kg) shifts forwards adds an EXTRA ten pounds (4.5 kg) of load on the neck and upper back muscles to keep the head upright.

So, what can be done for people who suffer from headaches? First, research shows chiropractic care is highly effective for patients with both types of headaches. Spinal manipulation, deep tissue release techniques, and nutritional counseling are common approaches utilized by chiropractors. Patients are also advised to use some of these self-management strategies at home as part of their treatment plan: the use of ice, self-trigger point therapy, exercise (especially strengthening the deep neck flexors), and nutritional supplements.

I get dizzy when I have a headache. Should I worry?

Vertigo_view_03,_Andels_Hotel_Łódź.jpg

Dizziness, neck pain, and headaches are very common symptoms that may or may not occur at the same time. Though this interrelationship exists, this month’s article will focus primarily on dizziness, particularly related to dizziness that occurs after standing.

First, it is important to point out that it is VERY common to be light headed or dizzy when standing up too fast, which is typically referred to as orthostatic hypotension (OH). OH is frequently referred to as a benign symptom, but new information may challenge this thought.

Let’s review what happens. When we are lying down, our heart does not have to work as hard as when we are upright; therefore, our blood pressure (BP) is usually lower while we lay in bed. When standing up, blood initially pools in the legs until an increase in blood pressure brings oxygen to the brain. This either resolves or prevents dizziness.

Orthostatic hypotension is defined as a blood pressure drop of >20 mm Hg systolic (the upper number—heart at FULL contraction), 10 mm Hg diastolic (lower number—heart at FULL rest), or both. This typically occurs within seconds to a few minutes after rising to a standing position.

There are two types of OH—delayed OH (DOH) where the onset of symptoms are not immediate but occur within three minutes of standing and “full” OH, which is more serious and occurs immediately upon rising. According to a 2016 study published in the prestigious journal Neurology, researchers reviewed the medical records of 165 people who had undergone autonomic nervous system testing for dizziness. The subjects averaged 59 years of age, and 48 were diagnosed with DOH, 42 with full OH, and 75 subjects didn’t have either condition.

During a ten-year follow-up, 54% of the DOH group progressed to OH, of which 31% developed a degenerative brain condition such as Parkinson’s disease or dementia. Those with initial DOH who also had diabetes were more likely to develop full OH vs. those without diabetes.

The early death rate in this 165 patient group was 29% for those with DOH, 64% with full OH, vs. 9% for those with neither diagnosed condition. The authors point out that those initially diagnosed with DOH who did NOT progress into full OH were given treatment that may have improved their blood pressure.

The authors state that a premature death might be avoided by having DOH and OH diagnosed and properly managed as early as possible. They point out that a prospective study is needed since this study only looked back at medical records of subjects who had nervous system testing performed at a specialized center, and therefore, these findings may not apply to the general population.

The value of this study is that this is the FIRST time a study described OH (or DOH) as a potentially serious condition with recommendations NOT to take OH/DOH lightly or view it as a benign condition. Since doctors see this a lot, a closer evaluation of the patient is in order.

Teens & Headaches? What?

Migrane

In 2016, researchers at Curtin University in Perth examined the seated posture and health data of 1,108 17-year olds in an effort to determine if any particular posture increased the risk of headaches/neck pain among late adolescents.

Among four posture subgroups—upright, intermediate, slumped thorax, and forward head—the researchers observed the following: participants who were slumped in their thoracic spine (mid-back region) and had their head forward when they sat were at higher odds of having mild, moderate, or severe depression; participants classified as having a more upright posture exercised more frequently, females were more likely to sit more upright than males; those who were overweight were more likely to sit with a forward neck posture; and taller people were more likely to sit upright.

While they found biopsychosocial factors like exercise frequency, depression, and body mass index (BMI) ARE associated with headaches and neck pain, their data did not suggest any one particular posture increased the risk of neck pain or headaches more than any other posture among the teenagers involved in the study.

This is noteworthy as studies with adults do indicate the risk for neck pain and headaches is greater in individuals with poor neck posture. In particular, postures such as forward head carriage, pinching a phone between the ear and shoulder, and prolonged neck/head rotation outside of neutral can all increase the risk of cervical disorders. This suggests that in younger bodies, the cause of neck pain and headaches may be multifactoral and not limited to just poor posture and that treatment must address all issues that may increase one’s risk for neck pain/headaches in order to reach a desired outcome.

The good news is that chiropractic has long embraced the biopsychosocial model of healthcare, looking at ALL factors that affect back and neck pain and quality of life. Through patient education, spinal manipulation, mobilization, exercise training, the use of modalities, and more, chiropractors can greatly help those struggling with neck pain and headaches!

What is Whiplash? 

WRD 2

Whiplash is an injury to the soft-tissues of the neck often referred to as a sprain or strain. Because there are a unique set of symptoms associated with whiplash, doctors and researchers commonly use the term “whiplash associated disorders” or WAD to describe the condition.

WAD commonly occurs as a result of a car crash, but it can also result from a slip and fall, sports injury, a personal injury (such as an assault), and other traumatic causes. The tissues commonly involved include muscle tendons (“strain”), ligaments and joint capsules (“sprains”), disk injuries (tears, herniation), as well as brain injury or concussion—even without hitting the head!

Symptoms vary widely but often include neck pain, stiffness, tender muscles and connective tissue (myofascial pain), headache, dizziness, sensations such as burning, prickly, tingling, numbness, muscle weakness, and referred pain to the shoulder blade, mid-back, arm, head, or face. If concussion occurs, additional symptoms include cognitive problems, concentration loss, poor memory, anxiety/depression, nervousness/irritability, sleep disturbance, fatigue, and more!

Whiplash associated disorders can be broken down into three categories: WAD I includes symptoms without any significant examination findings; WAD II includes loss of cervical range of motion and evidence of soft-tissue damage; and WAD III includes WAD II elements with neurological loss—altered motor and/or sensory functions. There is a WAD IV which includes fracture, but this is less common and often excluded.

Treatment for WAD includes everything from doing nothing to intensive management from multiple disciplines—chiropractic, primary care, physical therapy, clinical psychology, pain management, and specialty services such as neurology, orthopedics, and more. The goal of treatment is to restore normal function and activity participation, as well as symptom management.

The prognosis of WAD is generally good as many will recover without residual problems within days to weeks, with most people recovering around three months after the injury. Unfortunately, some are not so lucky and have continued neck pain, stiffness, headache, and some develop post-concussive syndrome. The latter can affect cognition, memory, vision, and other brain functions. Generally speaking, the higher the WAD category, the worse the prognosis, although each case MUST be managed by its own unique characteristics. If the injury includes neurological loss (muscle strength and/or sensory dysfunction like numbness, tingling, burning, pressure), the prognosis is often worse.

Chiropractic care for the WAD patient can include manipulation, mobilization, and home-based exercises, as well as the use of anti-inflammatory herbs (ginger, turmeric, proteolysis enzymes (bromelain, papain), devil’s claw, boswellia extract, rutin, bioflavonoid, vitamin D, coenzyme Q10, etc.) and dietary modifications aimed at reducing inflammation and promoting healing.

* 83% of those patients involved in an MVA will suffer whiplash injury and 50% will be symptomatic at 1 year.
* 90% of patients with neurologic signs at onset may be symptomatic at 1 year.
* 25- 80% of patients who suffer a whiplash injury will experience late-onset dizziness
* Clinicians should be observant for radiographic signs of instability, including interspinous widening, vertebral subluxation, vertebral compression fracture, and loss of cervical lordosis.
* Horizontal displacement of greater than 3.5 mm or angular displacement of more than 11 degrees on flexion/extension views suggests instability.

Trigger points and headaches

Trigger points are contracted knots of muscle tissue that form in any muscle as a result of overload stress. Trigger points cause pain, referred pain, stiffness and weakness. Trigger points that form in the muscles of the neck and head often refer pain into the head and face. This is one of the most common causes of headache pain. Trigger point massage is an effective way to treat trigger points.

Trigger points in the sternocleidomastoid muscle

The sternocleidomastoid muscle is a thin strap like muscle located on both sides of the front of the neck. It helps with movement and posture of the head and neck. This muscle often becomes shortened and tight in people with poor head forward  posture. As a result trigger points can form, and these points can cause pain to refer into the skull, and face around the eye. Trigger points in this muscle can also refer into the inner ear.
