A Glimpse Into China's Top Brain Hospital
The sounds of the city pass through the open window are overwhelming the microphone - car horns, construction machinery - and then there's the family at the adjacent bed talking loudly on cell phones, yet you can still hear the faint beep of our patients monitoring equipment.
A Commonly Missed Spinal Fixation: The Upper Lumbar Spine (Part 1)
When we think of lower back pain, we tend to think in terms of the lower lumbar spine and the SI joint. These joints and their discs are obviously important. However, we tend to miss fixations that occur just above – in the upper lumbar spine. Three questions come to mind: 1) Why is the upper lumbar spine so important? 2) Why do we miss the fixations here? 3) How can we adjust them?

Thoughts to Live By
When speaking to your patients about their health make sure to ponder the following points and have them assess if they are making themselves even more sick by the thoughts they have about life. Are these some of the traits and thoughts that your patients might have?
Get Ready For AOM Day
This year, AOM Day 2014 falls on Friday, (October 24th). This is a great opportunity to make your AOM Day celebration or event even bigger by extending it throughout the weekend!
History of Animal Acupuncture: Part II
In Part I of this article, I had gone back to 1969 and tried to describe the atmosphere and events of that year that engulfed many of the younger generation, some who were all the core members of the National Acupuncture Association.
The Spirit of the Point
After receiving a large amount of positive feedback on my San Zhen Protocols series, I have decided to focus this article on some relevant clinical aspects of acupuncture therapy prior to moving on to San Zhen Protocols III.
Help Secure Our Future by Sharing It
The National Board of Chiropractic Examiners (NBCE) conducts one of the most comprehensive surveys of the U.S. chiropractic profession every 4-5 years.
The Science Behind Happiness
Are you happy right now? Whether yes or no, there are a myriad of reasons why you feel that way. A whole academic discipline has developed to find out what causes or obstructs happiness, and how to amplify it.
Let the Patient Tell Their Story
Often when a patient presents with an injury, they want to tell their story. People by nature like to talk about themselves, particularly when they're worried about their health.
The Truth About Herbs
I appreciate the effort and research put into the article written in the June issue of Acupuncture Today regarding pesticides and Chinese herbs.
Uncle Sam Needs You
Scrutiny into the Department of Veterans Affairs (DVA) continues to grow after efforts to reform the DVA by the former Secretary of Veterans Affairs, Eric Shinseki, were deemed "a stunning period of dysfunction" by Senate Minority Leader Mitch McConnell (R-Ky.).

A Healthy Dose of Failure is Vital to Your Success
As an acupuncturist I tend to see people after they have already suffered for years and "tried everything." They are so desperate for some relief that they want to know everything about how to get better, right now.
Improving Our Political Effectiveness
The November 2014 elections are right around the corner; members of Congress, governors and state legislators are all running. Now is a good time to talk frankly about our overall political involvement.
Medicalization and Mindfulness
The past several years have seen a veritable explosion of research on mindfulness. Research abstracts we've published in each issue of Health Insights Today under the heading "Mind-Body News" have increasingly reported on studies about mindfulness interventions.
The Problem With Prolonged Sitting
We need to constantly talk to our patients about spending less time sitting and about what can go wrong with poor sitting postures. The fact is we sit too long in repetitive malpositions.

The foot provides dynamic stability for a person's entire body weight, while simultaneously maintaining flexibility for shock absorption and propulsion along uneven surfaces. As a result, there are unique biomechanical demands on the foot.One of the body's adaptations to these demands is through specialized movements in the foot, such as pronation. In order to fully understand pronation, let's look at some fundamentals of movement and mechanics.
Most joint movements of the body are described in one of the three cardinal planes: sagittal, frontal or transverse. While there are foot motions such as dorsiflexion and plantar flexion that occur in these standard planes, most foot and ankle motion is not adequately described by these planes. More commonly, motion of the foot at the ankle is in a diagonal or oblique plane. This oblique plane motion involves movement through all three planes. For example, pronation is a diagonal plane movement of the foot around an oblique axis that combines the primary cardinal plane movements of dorsiflexion, eversion and abduction of the foot.
The diagonal plane movement of pronation occurs normally during walking or running. Although the term pronation routinely is used to describe dysfunctional foot mechanics, a better description of the pathological problem is overpronation. Also called hyperpronation or excessive pronation, this biomechanical disorder involves too much pronation during gait. Overpronation results when an individual moves either too far, or too fast, through the phases of pronation, placing more weight on the medial side of the foot during gait.
Unless there is a severe, acute injury, overpronation develops as a gradual biomechanical distortion. Several factors contribute to developing overpronation, including tibialis posterior weakness, ligament weakness, excess weight, pes planus (flat foot), genu valgum (knock knees), subtalar eversion, or other biomechanical distortions in the foot or ankle. Tibialis posterior weakness is one of the primary factors leading to overpronation. Pronation primarily is controlled by the architecture of the foot and eccentric activation of the tibialis posterior.1 If the tibialis posterior is weak, the muscle cannot adequately slow the natural pronation cycle.
Another primary cause of overpronation is subtalar eversion, also called calcaneal valgus (Figure 1). When the calcaneus is everted, weight is forced onto the medial edge of the foot. The subtalar eversion of pronation is visible in a standing position and it's evident that increased weight is placed on the medial side of the foot (Figure 2). Obesity can cause overpronation because the additional weight produces subtalar eversion and forces the longitudinal arch to collapse.
Overpronation can be a contributing factor in other lower extremity disorders, such as foot pain, plantar fasciitis, ankle injuries, medial tibial stress syndrome (shin splints), periostitis, stress fractures and myofascial trigger points. Overpronation increases the degree of internal tibial rotation, thereby contributing to various knee disorders such as meniscal injury or ligament sprains. The effects of the postural deviation are exaggerated in athletes due to the increase in foot strikes while running and the greater impact load experienced. When running, three to four times the body weight is experienced with each foot strike.2 If overpronation exists, the shock force is not adequately absorbed by the foot and is transmitted further up the kinetic chain.
Overpronation is best viewed from the posterior while the individual is walking, such as on a treadmill. When viewed with the client in a standing position, the overpronated foot looks similar to calcaneal valgus, because subtalar eversion is a fundamental component of overpronation. Examine the shoes for evidence of excessive pronation. If the shoes have had sufficient use, there will be an exaggerated wear pattern toward the medial side of the shoe bottom.
Overpronation usually is corrected with orthotics and/or strengthening exercises for the tibialis posterior. Massage treatment can relieve myofascial trigger points in the tibialis posterior, and other muscles, and address any resulting neuromuscular dysfunction in the leg or foot. Biomechanical correction of overpronation might require orthotics, neuromuscular reeducation, or gait retraining methods, as well. Stretching the gastrocnemius and soleus muscles will reduce hypertonicity in these muscles and also is essential for effective treatment.1 Because of impacts throughout the remainder of the body, the detrimental effects of overpronation should not be overlooked.
