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.
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.
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.
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.
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.
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.
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.
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.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.

Advanced Stretching: Using Neural Inhibition to Enhance the Stretch, Part 2
By Joseph E. Muscolino, DC
In part 1 of this series, we discussed contract relax (CR) stretching, which involves neural inhibition to augment the mechanical stretch of the target musculature.Here, in Part 2 of this series, we will discuss agonist contract (AC) stretching, which also uses neural inhibition to augment the mechanical stretch of the target musculature.
Similar to CR stretching, AC stretching also relies upon a neurologic reflex. However, whereas the Golgi tendon organ (GTO) reflex is the proposed neural mechanism for CR stretching, reciprocal inhibition is the proposed neural mechanism for AC stretching. The mechanism of RI is that whenever a mover muscle contracts and shortens to create a joint action, the antagonist musculature (that is usually located on the other side of the joint) must lengthen to allow that motion to occur. RI reflex acts to facilitate the lengthening of the antagonists by inhibiting them from contracting. This inhibition causes a relaxation so that the antagonists more effectively lengthen. As with the GTO reflex, we can take advantage of this reflex to create a better stretch.
AC stretching is performed by creating a scenario in which the target muscle that will be reciprocally inhibited is the antagonist to the joint motion that is performed. The usual AC stretching protocol steps are carried out as follows. The right lateral flexor (RLF) musculature of the neck are used as the example (Fig. 1):
a. Have the client begin in a neutral starting position.
b. Ask the client to actively concentrically contract the left lateral flexion (LLF) musculature, moving the neck into LLF. By doing this, the target RLF musculature is the antagonist of the motion. Their stretch is begun and the RI reflex is triggered. The client usually exhales during the contraction (think "e" for exhale and "e" for exertion).
c. The client then relaxes and we further stretch the client into LLF. The client usually completes the exhale during this step.
d. The client continues to relax as we passively bring the client back to the starting position. The client inhales during this step so she is ready for the next repetition.
Typically eight to 10 repetitions are performed, and we progressively increase the force of the stretch with each repetition. Because a large number of repetitions are performed with AC stretching, each repetition is usually performed fairly quickly. An entire repetition takes approximately 3-5 seconds.
Comparing CR and AC Stretching
To more easily learn these techniques, it can be helpful to compare CR with AC stretching. With CR stretching, the target muscle group isometrically contracts against our resistance. (Note: Part 1 of this series, the target right lateral flexors isometrically contract.) With AC stretching, the target muscle group is turned into the antagonist of the joint motion. Note that in Figure 1a, the left lateral flexors concentrically contract (again the right lateral flexors are the target musculature). It can help to remember that with AC stretching, the client's contraction actually begins the stretch of the target musculature.
Contract Relax Agonist Contract Stretching:
CR and AC stretching can be combined to create contract relax agonist contract (CRAC) stretching. As its name implies, a CRAC stretching repetition is done by sequentially performing the CR and then the AC stretching techniques. The benefit of CRAC stretching is that it triggers both the GTO and the RI reflexes, therefore potentially creating a more powerful inhibition/relaxation of the target musculature. The usual CRAC stretching protocol steps are carried out as follows. The RLF musculature of the neck are again used as the example (Fig. 2):
a. Have the client begin in a neutral starting position.
b. Ask the client to gently isometrically contract the target RLF musculature against our resistance for approximately 5-8 seconds to trigger the GTO reflex. The client holds in the breath during this step. This is the CR portion of the stretch.
c. Then ask the client to concentrically contract the LLF musculature to move into LLF. This begins the stretch the RLF musculature and it triggers the RI reflex. The client exhales during the contraction. This is the AC portion of the stretch.
d. The client then relaxes and we further stretch the client into LLF.
e. We then passively bring the client back to the starting position as the client inhales. This completes one repetition.
Three to five repetitions are usually performed, each one beginning from the same neutral starting position, as is done with AC stretching. Typically, the client is asked to increase the force of contraction with each repetition, and we progressively increase the force of the stretch with each repetition.
Most every stretch can be performed as a CR or an AC stretch, or even a CRAC stretch. Both CR and AC advanced stretching techniques are equally effective. Which one you choose to use will most likely depend upon client preference and which technique is logistically easier for that particular muscle and the position that the client is in. Advanced stretching techniques might take a little more time, effort, and practice to master, but the benefits to your clients are well worth it.
