“The most recent research (Neck Pain Task Force Report of the Bone and Joint Decade 2000-2010, a study sanctioned by the United Nations and the World Health Organization) indicates neck manipulation is a safe and effective form of health care,” according to the medical journal Spine.

Dr. Cassidy was an investigator with the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders. The work of this international task force affirms the safety and benefits of chiropractic care for people with neck pain—a condition frequently treated by doctors of chiropractic.

The study, which analyzed nine years’ worth of data from a population of 110-million person years, concluded that vertebrobasilar artery (VBA) stroke is a very rare event and that the risk of VBA stroke following a visit to a chiropractor’s office appears to be no different than the risk of VBA stroke following a visit to the office of a primary care medical physician (PCP).

The study goes on to say that any observed association between VBA stroke and chiropractic manipulation—as well as its apparent association with PCP visits—is likely due to patients with an undiagnosed vertebral artery dissection seeking care for neck pain and headache prior to their stroke.

Over the years, popular media has all too often sensationalized the association between chiropractic cervical manipulation and cerebral vascular accidents—even though the evidence would strongly indicate that this assertion is incorrect. The organizations representing the chiropractic profession believe this most recent evidence should help to dispel any myths on this issue, as well as provide more data to support the safety and effectiveness of chiropractic procedures.

As a profession, doctors of chiropractic remain committed to expanding the research and clinical understanding of VBA injuries, because even one cerebral vascular incident that could have been prevented or detected early is one too many.

Many of my patients know that sometimes I often look to the jaw to determine if there is any dysfunction even though the person may not be complaining out jaw or TMJ pain. That is because the TMJ influences the body as  a whole. This new study looks to how the dysfunction in the jaw reduces hip range of motion.

• Have you had an injury to the jaw?
• Do you grind your teeth (maybe as you sleep)?
• Do you clench your teeth when your nervous?

I know this concept is a big one so I’ll give you some time to chew on it as you read the abstract.

Influence of the temporomandibular joint on range of motion of the hip joint in patients with complex regional pain syndrome.

OBJECTIVE: This study evaluated if patients with complex regional pain syndrome (CRPS) would have an increase in range of motion (ROM) after myofascial release and a similar ROM decrease after jaw clenching, whereas in healthy subjects these effects would be minimal or nonexistent. METHODS: Documentation of patients with CRPS (n = 20) was established using the research diagnostic criteria for CRPS, questionnaires, average pain intensity for the past 4 weeks, and the temporomandibular index (TMI). Healthy subjects (n = 20, controls) also underwent the same testing. Hip ROM (alpha angle) was measured at 3 time points as follows: baseline (t1), after myofascial release of the temporomandibular joint (t2), and after jaw clenching for 90 seconds (t3). Comparison of the CRPS and control groups was made using t tests. RESULTS: Mean TMI total score and mean pain reported for the last 4 weeks were significantly different between the 2 groups (P < .0005). Hip ROM at t1 was always slightly higher compared to t3, but t2 was always lower in value compared to t1 or t3 for both groups. The differences of all hip ROM values between the groups were significant (P < .0005). Moreover, the difference between t1 or t3 and t2 was significantly different within the CRPS group (t1 = 48.7 degrees ; t2 = 35.8 degrees ; P < .0005). CONCLUSIONS: The results suggest that temporomandibular joint dysfunction plays an important role in the restriction of hip motion experienced by patients with CRPS, which indicated a connectedness between these 2 regions of the body.

I often hear people say they’ll just take a Motrin before the race. Let’s wait one minute and review the research…

This great New York Times article summarizes some remarkable research.

Those runners who’d popped over-the-counter ibuprofen pills before and during the race displayed significantly more inflammation and other markers of high immune system response afterward than the runners who hadn’t taken anti-inflammatories. The ibuprofen users also showed signs of mild kidney impairment and, both before and after the race, of low-level endotoxemia, a condition in which bacteria leak from the colon into the bloodstream.

The researchers were disturbed when the also found out that the majority of racers (70%)  utilized ibuprofen in this way.

One of the most common reasons cited by the triathletes in Brazil was “pain prevention.” Similarly, when the Western States runners were polled, most told the researchers that “they thought ibuprofen would get them through the pain and discomfort of the race,” Nieman says, “and would prevent soreness afterward.” But the latest research into the physiological effects of ibuprofen and other NSAIDs suggests that the drugs in fact, have the opposite effect. In a number of studies conducted both in the field and in human performance laboratories in recent years, NSAIDs did not lessen people’s perception of pain during activity or decrease muscle soreness later. “We had researchers at water stops” during the Western States event, Nieman says, asking the racers how the hours of exertion felt to them. “There was no difference between the runners using ibuprofen and those who weren’t. So the painkillers were not useful for reducing pain” during the long race, he says, and afterward, the runners using ibuprofen reported having legs that were just as sore as those who hadn’t used the drugs.

Moreover, Warden and other researchers have found that, in laboratory experiments on animal tissues, NSAIDs actually slowed the healing of injured muscles, tendons, ligament, and bones. “NSAIDs work by inhibiting the production of prostaglandins,”substances that are involved in pain and also in the creation of collagen, Warden says. Collagen is the building block of most tissues. So fewer prostaglandins mean less collagen, “which inhibits the healing of tissue and bone injuries,” Warden says, including the micro-tears and other trauma to muscles and tissues that can occur after any strenuous workout or race.

The painkillers also blunt the body’s response to exercise at a deeper level. Normally, the stresses of exercise activate a particular molecular pathway that increases collagen, and leads, eventually, to creating denser bones and stronger tissues. If “you’re taking ibuprofen before every workout, you lessen this training response,” Warden says. Your bones don’t thicken and your tissues don’t strengthen as they should. They may be less able to withstand the next workout. In essence, the pills athletes take to reduce the chances that they’ll feel sore may increase the odds that they’ll wind up injured — and sore.

My input: Your body is smart. The drug shifts the bodies normal responses and therefore leads to slower healing, increased likelihood of injury, and no reduction in pain. Follow a stricter training program so you gradually work up and if there is pain after a race see a chiropractor to make sure your body is performing and  a massage therapist to soothe the muscles.

I rarely just share an article as is but this one is a quick and fun one from ToYourHealth.com:

It’s a well-known saying that may actually be true, according to a number of studies. Evidence suggests laughter is a true health promoter, helping reduce stress, boost your heart rate, increase circulation, and even burn calories.

For example, laughter helps combat stress, which is well-known to decrease immune-system response. Less stress means a better immune system, making your body less prone to infection and disease. Reducing stress levels also makes it easier to fall asleep, and as has been discussed in this publication on several occasions, poor and/or inadequate sleep can contribute to a whole host of negative health consequences.

But how could laughter possibly burn calories? It’s actually a simple concept, if you think about it: When you laugh, your body moves in various ways; muscles throughout the body stretch and, depending on the strength of the laugh, your abdomen and other areas of the body may even contract repeatedly. Now that’s a workout and a laugh all in one!

So go ahead and rent a funny movie tonight or check out a local standup routine, laugh-doctors orders.
