In This Current Age of Anxiety
Anxiety, also referred to angst or hysteria, goes by many names. One, popularized by the sagacious Zhang Zhong Jing, who many practitioners of Chinese Medicine may be familiar with, is known as Restless Zang/Fu disorder.
Low Fat vs. Low Carb & the Power of Protein
A science-based website recently posted a nice summary of 23 randomized, controlled trials from peer-reviewed journals pitting low-carb diets against low-fat diets.
Discovery: Finding Insights and Each Other in Different Disciplines
Recently I've been thinking about all sorts of things which are hidden from our daily direct experience. That general category is what links nearly everything that catches my attention and then demands some kind of investigation.
Keeping Malpractice Allegations at Bay
It has been suggested that in the litigious environment in which we live, the practice of chiropractic should be defensive and practitioners should constantly be watching their backs. An element of defensive practice is a good idea.
Sleepless nights, anxiety, mood swings, euphoric energy bursts, obsessive thinking, and a strange feeling in his chest. That is what Matt was experiencing when he first entered my practice. Rather than being concerned, he was loving every minute of it.
Streamline Your Front Desk
Your front office can be your greatest source of efficiency or it can be a constant bottleneck. Increasing the productivity of this area, while not sacrificing the quality of patient interaction, can be a little tricky. However, with some focused effort and intention, your front desk can keep your practice running smoothly.
A Different Way of Looking at It
The way you and your chiropractic colleagues access information has changed over the past decade. According to a recent survey conducted by Dynamic Chiropractic, almost half (48 percent) of DCs read online articles on their personal computer or laptop daily.
A Whole-Body Approach to Chronic Tension Headaches
Nearly every day in our practices, we see patients with chronic headaches that have not responded to traditional treatment. They present in our offices with a feeble hope that "maybe" a chiropractor can help.

Constructing Our Reality, Part 2
My last article discussed perception and its relationship to the primary channels. Before we get to the channels most commonly used to treat sensory disturbances, the small intestine and triple heater, we should first talk about the bladder channel.
Living Well: Lessons From Our Oldest Old
Aging is a significant public health problem, important to chiropractors in practice and important to DCs who teach students training to become chiropractors.
Finger (Pad) Pointing: Repetitive-Use Injury Waiting to Happen
"My wrist and hand hurt. I spend all day working on computers and then I come home and spend more time on a computer, usually playing video games."
One of the most common trends to see in clinical medical practice and public health is the cycles of health "buzzwords." These come and go depending upon the current cultural zeitgeist. One year, "parasites" are causing all the issues, and the next year it's "candida."
With Low-Back Pain, Sometimes Little Things Matter
Typical treatments for low back pain involve large muscles like the quadratus lumborum, iliopsoas, and piriformis. However, there are situations when a very small muscle, the multifidus, can play a significant role in the diagnosis and treatment of low back muscular or spinal injury.
Building Bridges with Discipline
As practitioners of traditional Chinese herbal medicine, our role is to educate patients and medical practitioners about the various safety aspects of our medicine. Medical doctors that embrace Chinese medicine want to collaborate and include Chinese herbal medicine in more aspects of clinical care to support their patients.
How to Reach Your World With the Chiropractic Message
My latest effort to share chiropractic occurred in mid-May while I was sitting at an introductory parent information night for high schoolers. The IT instructor informed us that each student would be receiving a computer for all their studies.
Distal Style Treatment of Neurogenic Pain
Treat locally or distally? This question has frequented my thoughts for the treatment of pain throughout my acupuncture career. Each style has strengths and weaknesses, thus the versatile practitioner would do well to forgo dogmatic adherence to any one style in deference to the needs of the individual patient.
Parker University Embraces New Era
Change is in the air at Parker University, which recently announced the selection of both a new president and a new consultant for its seminar program.
The Need for Standards
ISO-TC-249: You may look at these letters and numbers and wonder what they are and what they might mean. They turn into: International Standards Organization- Technical Committee – 249. There is a global organization called The International Organization for Standardization.
Billing One-on-One, Direct Patient Contact
This is often misunderstood and leads to trepidation when documenting and subsequently billing timed services.
Holistic Skin Care and Modern Technology
Anti-aging is a concept that we hear in reference to skin rejuvenation and growing older on a daily basis. Aging begins as soon as we are born; therefore "pro-aging" is embracing all stages of life gracefully, with vitality, wisdom, joy, and gratitude as the goal.
Prostate Cancer Risk
A large study published in January 2016 in the American Journal of Clinical Nutrition showed that men who are vegans had a 35% lower risk of developing prostate cancer compared to non-vegan men. The study followed more than 26,346 men who are part of the Adventists Health Study-2.
Understanding Levels of Evidence
The concept of levels of evidence is a cornerstone of research literacy and a great starting point for understanding basic principles of how research works.
Billing Timed Services
Q: I do not always use physical medicine services but in my state I do have a scope of practice that allows me to provide many of these services. I am trying to understand what "direct one-on-one patient contact" means in relation to physical medicine services.
Hip Flexor Contractures & LBP in Above-the-Knee Amputations
Patients with above-the-knee amputations (AK or AKA) are particularly prone to developing hip flexor contractures. Not to be confused with muscle tightness, contractures are a permanent shortening of tissues which cause deformity or distortion.

The Bike Body
Working With Cyclists
By Erik Dalton, PhD
It's astonishing the money and time many elite and "weekend-warrior" cyclists devote to retrofitting racing bikes to conform to their bodies rather than first restoring function to the most critical piece of racing equipment: the rider's body.When muscle imbalances, faulty movement patterns and joint fixations distort the body's bony framework, the cyclist is led on a never-ending journey searching for that perfect bike fit. (Fig. 1)
My personal mantra: "Fit the body to the bike, stupid!"
Bodyworkers and functional movement trainers whose practices cater to amateur and elite cyclists are keenly aware of the clinical and performance advantages gained by restoring optimal mobility, flexibility and stability to the biker's muscle/joint complex. It makes sense to first get the kinks out before sending the client off for an expensive and sometimes useless bike retrofit. Without hands-on maintenance and functional fine-tuning, cyclists often unknowingly reinforce dysfunctional movement patterns ingrained from long-forgotten micro- or macro-traumatic injuries.
Confusion and controversy over this chicken-or-egg (bike-or-body) thing is primarily due to lack of understanding of the Law of Cause and Effect. For instance, let's say a bike shop performs a retrofit and Bob, the cyclist, smilingly pedals away on his newly reconstructed machine feeling secure and pain-free. Life is good... or is it?
Unfortunately, if Bob is one of many "flexion-addicted" Americans with a sedentary job that keeps him glued to the computer terminal day-after-day, gravitational exposure will gradually drag his body into a big "C" curve. (Fig. 2) In time, Bob's brain relearns this aberrant posture as normal and on weekend outings his "hip-flexed" desk posture morphs into a similarly distorted riding posture. (Fig. 3)
To make matters worse, stubborn pain-spasm-pain cycles often appear as the hip stiffens and the imposed stress destabilizes sacroiliac and low back structures. In the presence of lumbar spine instability, the brain may decide to lock down the low back and ribcage with protective muscle guarding. Thoracic cage rigidity not only inhibits proper diaphragmatic breathing but also sends shock waves through the thoracolumbar and pectoral fascia and into the upper extremity joints where reverberations are met with strong resistance from habitually locked hands, elbows and arms. (Fig. 4) Meantime, compensations from adhesive hip capsules also traverse down through Bob's knees, ankles and feet searching for a weak link in the lower kinetic chain.
Cyclists who opt for a bike retrofit prior to receiving manual therapy to release fibrotic hip capsules and hip flexors, soon notice a loss of endurance and may develop soft tissue or joint sprains associated with lumbopelvic imbalance. Oddly, many flexion-addicted cyclists attempt to work through the injury despite sensing a noticeable reduction of speed, power and efficiency. "No pain, no gain" is an unacceptable working model for those seeking longevity in the cycling sport.
Does decreased hip angle equal less power?
One of the most common bike positions used by "flexiholics" has the hip flexors locked short and the hams and glutes overstretched and weak. This imbalance pattern as described by Vladimir Janda in his lower crossed syndrome, forces the pelvic bowl to be drawn too far forward creating a decrease in hip angle. (Fig. 5)
Cyclists who consistently ride with an anteriorly rotated pelvis and decreased hip angle are subject to capsular and ligamentous adhesions and a subsequent loss of economy and power. To accommodate the loss of hip extension, many recreational and competitive racers compensate by posteriorly tilting their pelvic bowl and rounding their backs into a hyperkyphotic posture just to increase hip angle and power. The famed cyclist Andy Pruitt believes that changing the seat height by a mere inch alters mechanics and motor control patterns of every joint in the lower extremity. By decreasing seat height, excessive force is transferred to the patellofemoral joint, while raising the saddle too much strains the hamstrings, low back and hands.
Stand and try this: Lift one leg with the knee bent about 90 degrees as high as possible without straining or rounding the back and forcing hip flexion. Most people are able to comfortably hip-flex about 90 degrees. Try this maneuver again except this time forward-bend your trunk about 50 - 60 degrees, while raising the knee. Notice a dramatic reduction in the amount of hip flexion? Try both tests again and this time, measure available hip flexion by observing how high your foot raises off the ground. This test illustrates what can happen to hip-impaired cyclists: decreased hip flexion = greater effort = more work = poor performance.
Riding Postures and Rehab
The first order of business when treating adhesive (motion-restricted) hip flexors and capsules is to mobilize the hip in all three cardinal planes. (Fig. 6a) To restore myofascial balance, fast-paced "spindle-stim" maneuvers such as those shown in Fig. 6b help tonify weakened (neurologically inhibited) gluteal and hamstring muscles. Once the therapist manages to increase hip angle and establish proper functional balance and range of motion, the cyclist is free to decide which type of riding posture (he believes) suits him best.
Some cyclists prefer a high seat so they can posteriorly rotate the pelvis to increase hip angle. Other riders find greater mechanical advantage by putting a little curve in the low back, engaging the core, and then slightly backing off the curve to allow a neutral lumbar spine. Either way, both groups should avoid:
The Yin-Yang of Muscles and Joints
To perform well in such a challenging event, cyclists like Bob would greatly benefit from a well-constructed manual and movement therapy program that focuses on restoration and maintenance of proper intrinsic/extrinsic muscle balance and diaphragmatic breathing patterns. Fluid and dynamic body movement during cycling events is dependent on the ability of muscles and fascia to stay strong, yet flexible. A healthy lumbar spine is the driving engine in most athletic endeavors and length/strength balance between muscles, ligaments, joint capsules, and thoracolumbar fascia is essential for providing that stable platform. Any weakness or motor control issues are magnified by traumatic shocks from funky road conditions or recurring bike injuries. Eventually, excessive neurological input cannot be handled at the spinal cord level and the information is "fast-tracked" to the brain for interpretation via pain-signaling nociceptors. If the brain decides to "splint" the vulnerable area to prevent further insult, pain-spasm-pain cycles may ensue.
Ingrained muscle and motor imbalance patterns such as those discussed by Vladimir Janda, Gray Cook, Craig Liebenson and others, often require a concerted team effort to reestablish normal movement behavior. In most cases, the ideal treatment protocol is to first restore lost mobility to impaired structures and then address stability issues via functional movement training.
Like many of America's other popular, but abnormal, athletic endeavors such as golf, tennis, bowling, etc., cyclists bring with them a complex biomechanical downside that's often hard to completely fix. The "arched back" model is generally the most problematic. In an attempt to level the eyes, the rider must hyperextend occiput on atlas. The cervicothoracic junction is also forced to hyperextend (neck-on-shoulders) causing chronically locked intervertebral joints and rib jamming. This area is particularly affected by road vibrations due to the stationary position of arms, shoulders and hands. Additionally, ligamentous laxity may develop from excessive thoracolumbar and lumbosacral bowing which, in time, sets the stage for low back pain and disability.
The good news is that the human body is both adaptable and dynamic; the bad news is that our biker clients often bring along a lot of baggage including flexion-addicted sitting postures, old injuries, compensations, poor training habits, etc. Once the skilled manual and movement therapist makes necessary corrections, the bike can then be retrofitted to conform to the rider's optimally functioning body. A properly fitted bike combined with a revitalized and functionally balanced neuromuscular system allows muscles and joints to work at optimal levels of motor unit recruitment and synchronization. As endurance and performance improve, so does the natural love of cycling.
