Six Things Every DC Should Know About the Zika Virus
The Zika outbreak continues to spread across the continental United States and U.S. territories. We offer this brief overview on this important public health problem for the practicing doctor of chiropractic.
U.S. Olympians Have a DC in Their Corner
It's probably old news to you that doctors of chiropractic play an increasingly prominent role in treating athletes, from youth sports participants to weekend warriors, to elite / professional competitors.
Four Ways to Attract Patients
Acupuncturist A has been in practice for six years and has struggled since day one. She spends as much time and money on marketing as she can, but since her practice is slow, her budget isn't that big.
Power to the Patient
Against a backdrop of splintered political parties, polarizations within nations, civil unrest, and distrust of established government (such as the growing anti-Washington, D.C. sentiment) comes the not-so-surprising finding that health care authorities and practitioners (with perhaps the exception of insurers) are turning over more and more powers to the individual patient.
Getting Paid by Medicare Is Getting a Major Adjustment
The 2015 Medicare Access and CHIP Reauthorization Act (MACRA) was signed into law to implement a new approach to clinician payments and replace the Sustainable Growth Rate formula.
Integrative Cancer Care: Chiropractic for Chemotherapy-Induced Hiccups
Hiccups (singultus) are a frequent occurrence during cancer treatment. The cause of the hiccups may be the chemotherapy drug itself, such as Cisplatin; or the prophylactic use of corticosteroids such as Decadron, which is used to prevent nausea and/or vomiting.
ITB Syndrome: Treat the Tensor Fascia Latae
Iliotibial band syndrome is usually the result of repetitive knee flexion, such as in runners or cyclists. Pain may be experienced in the knee and/or the hip. The patient may express a sense of the hip dislocating, popping or snapping.
National Board Apologizes for Testing Issues
The National Board of Chiropractic Examiners (NBCE) has issued a formal apology following a series of computer-based testing malfunctions that impacted two separate examinations (March and June 2016) and caused "widespread confusion and frustration" to the nearly 1,500 examinees taking the tests.
Decoding the Mystery of Medical Insurance Acceptance
In the constantly evolving profession of acupuncture, one of the least understood areas is medical insurance acceptance. The profession is filled with controversy surrounding this topic: Is it ethical?
Dysautonomia: The Medical Condition You May Already Be Treating
TCM practitioners have spent thousands of years healing patients without knowing or needing the names of their diseases as defined by allopathic medicine. We have syndrome names that are both poetic and efficient.
Treating Peripheral Neuropathy: Multi-Faceted Approach Including Laser Therapy
Peripheral neuropathy affects at least 20 million people in the United States1 and nearly 60 percent of all people with diabetes suffer from diabetic neuropathy. Many suffer from the disorder without ever identifying the cause.
Pediatric Asthma: A Case Study
I have had very good success with pediatric asthma, combining acupuncture with Chinese herbal products. Treatment is given over four to eight months, twice monthly, with herbal formulas rotated every month.
Workers' Back Pain: Causes, Costs & Solution
You will want to share two important papers published in the past several months. Why? When read separately, each provides valuable information relevant to your patients, community and practice; together, they tell a compelling story.
Treatment Success at the Won Institute
According to the World Health Organization's 2003 report titled, "Acupuncture: Review and Analysis of Controlled Clinical Trials," acupuncture has been shown to improve many physical, emotional, and mental conditions.
Pediatric Footwear: Function Over Fashion
As practitioners, it is not uncommon for parents to bring us their children to treat or ask us questions related to the pediatric population. Children's feet tend to be a perplexing region for parents and practitioners alike.
Natural Cancer Prevention: Pomegranate for the Prostate
In recent years, the ingestion of pure pomegranate juice (8 ounces per day) has been shown in clinical studies with human subjects to slow, and to some degree, reverse, the progression of prostate cancer – the second leading cause of cancer death in North American men.
Update from the International AIDS Conference
The 21st International AIDS Conference in Durban, South Africa, brought together more than 15,000 of the world's leading scientists, activists, funders, policy makers, and consumers from 153 countries.
First Annual ICD-10 Updates Take Effect
Yes, there was an update to ICD-10 codes on Oct. 1. It was a regular update to the diagnosis coding system and will take place every Oct. 1, just as it did when the ICD-9 system was in place.
Going Beyond Just Feeling Good
We all know that most patients come to us for some pain complaint: neck pain, back pain, sciatica, carpal tunnel, etc. We also all know that acupuncture is a great first-line care for these issues, as well as supporting overall health and wellness.
Upgrade to "Parker 2.0" in Las Vegas
Continuing your education and refining your practice: two key elements of a successful chiropractic career. Parker Seminars promises both as it celebrates its 65th anniversary in Las Vegas next February, according to Parker University President, Dr. William Morgan, and seminar consultant Dr. Mark Sanna.
Using the Lens of Chinese Medicine
One of the most common medications I see in clinical practice on a daily basis is fluoxetine or Prozac. Consequently, I hear many complaints concerning the side effects of this medication and am frequently asked by patients to help manage these side effects with acupuncture and Chinese medicine.

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.
