Muscle testing and what it does for you!

Muscle testing is used by a wide variety of practitioners, including those in medicine, osteopathy, chiropractic and physical therapy.  For example, neurologists may perform it to help rule out serious conditions; physical therapists to rate a patient’s level of disability; athletic trainers to assess a particular injury; and chiropractors to help determine areas of treatment. Overall, practitioners who employ biofeedback, manipulation, diet and nutrition, exercise, sports, coaching, and other approaches, often utilize muscle testing.

Dr. Dan Walker has used Muscle testing for almost 20 years.  He has helped countless amounts of people with problems from Professional Athletes, Musicians, Blue and White collar workers, weekend warriors and children.

Muscle testing is used by Doctors as part of a physical exam. It helps show the body’s muscles and their connections to the brain through the nervous system. Testing is performed by applying moderate and precise force against an arm, leg or other body area of a patient who is simultaneously resisting in the opposite direction. This testing is particularly important because those with back, knee, hip pain, spinal problems, wrist and elbow dysfunction, headaches, and many other disorders need answers.

Testing muscles is a primary and practical way to determine a condition called muscle imbalance, where two or more muscles are not properly working together.  It is like when your favorite team goes out to play but some of the players are sick and just not playing well – the whole team suffers.  Muscle imbalance is a common cause of injury, pain, and disability, the use of muscle testing can be as important as blood, urine, X-rays, and physical examinations.  But much quicker!

While associated with joint, ligament, tendon, and bone problems, muscle imbalance can significantly impair physical movement, such as walking, reduce sports performance, and even lower the overall quality of life.

A term commonly associated with muscle testing is kinesiology, referring to the study of human movement. It is a topic taught in the coursework of many colleges, universities, and postdoctoral programs. Through an understanding of kinesiology, practitioners can better use muscle testing to evaluate posture, gait, and all other movements.

Tens of thousands of health practitioners around the world, in hospitals, clinics, private practice, on sports teams, and elsewhere, employ some form of muscle testing in their work. In addition, hundreds of studies have been published in scientific journals on this topic.

As an important part of a comprehensive physical evaluation, muscle testing can help discover the cause of a particular injury or disability. It can also quickly assist in measuring the effectiveness of specific treatments.

So if you know you are not performing the way you should, you know something isn’t right and you are ready for a change from Drugs and Surgery come get a muscle check!

Massage Therapist

massage-room   JoAnn Hailwood – Licensed Massage Therapist A.K. Chiropractic at Erie’s Reviving Bodywork Studio

I have been practicing Massage Therapy since graduating from Great Lakes Institute of Technology and Medical Careers in October of 2002. The year long course provided a solid foundation on which I’ve built my practice. The course studies included 100 hours of Anatomy and Physiology, Deep Tissue Massage, Trigger Point Therapy, Shiatsu, Reflexology, Swedish Massage and Aromatherapy.

I branched into Energy Work in late spring of 2005 when I attended a weekend workshop with Alex Hermasillo of Sedona, Arizona; development of a technique he refers to as Master Energy Medicine (MEM). In that intensive weekend we received training in Reiki level 1, 2, and 3 and level one of MEM. I learned of the Chakra system: seven subtle anatomy centers that run from the tailbone to the crown of the head, and hold our life experiences. I learned 0f the impact of our emotional bodies along with our ancestral connections in our present life. I studied with Alex via his weekend workshops to complete level 4 MEM by the end of 2005.

I have been privileged to work with many gifted practitioners over the years who have eagerly shared their knowledge and experience with me. I am deeply grateful to them all.

I have continued to study Alternative Modalities in both bodywork and energy healing. My Continuing Education courses for licensing have been focused on attaining a deeper level of understanding of how the mind, body, and the Spirit work together to make life not only manageable, but enjoyable.

I offer 60 to 90 minute session tailored to your personal needs. These sessions may include, in bodywork, Swedish massage, Deep Tissue, Trigger Point, Cranial Sacral and Myofascial release.

60 minute Energy Work sessions draw from Reiki, Polarity Balancing, Quantum Touch, and Emotional Release techniques.

90 minute session can be tailored to include both Massage and Energy work.


Dr. Walker is in my opinion, one of the finest Chiropractors out there. He explains what he is doing, why he is doing it and how it is going to help alleviate your pain. If you ask me with each adjustment, he gives away the secrets on what he is doing. I have been going to Dr. Walker for over 10 years now and I would recommend him to anyone.

Is Sitting the New Smoking?

Is Sitting the New Smoking?

A recent article published by the Harvard Business Review equates sitting with smoking in terms of long term risks to health and well being. Considering all we know now about the dangers of tobacco use, this seems like an extreme claim to make. However, with many spending their days working at sedentary jobs and their nights on the couch, you can see how the hours add up. Combine that with what we know about how excess weight and lack of exercise can affect the body and you can see how all the time spent in a chair can start to take a serious toll.

People spend an average of 9.3 hours per day sitting, which is even more than we spend sleeping. This includes time in front of computers, working at desks, in meetings, and leisure time at home. Extensive research has been done on the effects this has on the body. After just one hour, the enzymes that burn fat decline significantly, increasing the risk of obesity and type 2 diabetes and associated degenerative diseases, like arthritis. Study after study has also shown that a lack of daily movement also increases the risk colon cancer and breast cancer, as well as cardiovascular disease and heart attack.

 When taken all together, time spent in a chair does stack up as just as dangerous as smoking.

For many people, their occupation may make it difficult to change the amount of time spent in front of computers. That’s why it’s important to make decisions about how to spend your time outside of work to counteract all the daytime inactivity. Walks after dinner or recreational sports on the weekends may be a perfect fit for some. Others might find it possible to take standing breaks during the day, or even construct a standing desk. Even small changes can make a big difference.

For a long time, tobacco use has been touted as one of the most dangerous bad habits, and many people have quit knowing the dangers. It doesn’t seem likely, though, that as many people would be willing to give up their couches and chairs. If presented with the data and statistics tabulating the risks of spending time at a desk or in front of the television, though, people would be surprised to learn that the health dangers are as significant as lighting up.


A “Master”-ful Win for Chiropractic

A “Master”-ful Win for Chiropractic

In early April, the world watched as 21 year old Jordan Spieth became the second-youngest golfer to win the Masters Tournament, one of golf’s elite tournaments.

Spieth credited his team for his stellar performance, including chiropractor Dr. Troy Van Biezen. Four out of five golfers experience back pain due to the repetitive motion of swinging a golf club and Spieth said that he has received chiropractic care since he was 14 and continues to receive care daily to maintain optimum health and overall athletic performance.

Following a record-breaking win at the 2015 Masters Tournament, 21 year-old Jordan Spieth recognized those who significantly contributed to his victory, including his doctor of chiropractic Troy Van Biezen, Dallas Texas. Since the age of 14, Spieth has relied upon chiropractic care to prevent injuries as well as optimize overall health and athletic performance.

“Dr. Van Biezen is an important member of my team and, thanks to his care, my all-time dream of winning the Masters Tournament has now become a reality,” states Jordan Spieth.

Noting that four out of five golfers experience back pain as a result of repetitive swinging, Dr. Van Biezen says, “Since a very young age, Jordan has aspired to win the Masters and has since applied great discipline to achieve this goal. Many athletes, and especially golfers, understand the significance to spinal and pelvic motion to functional performance.”

Doctors of Chiropractic are fully trained in every area of health and healing. Doctors of Chiropractic must have a Bachelor’s degree before being admitted, they must complete their “Pre-Med” elbow to elbow with the other prospective M.D., D.O., D.D.S., and D.V.M.  students.  Once accepted into Chiropractic College students are taught an almost identical curriculum as every medical professional for four years, up to the point where every doctor must specialize.

Why and How to Say No to an Unnecessary Root Canal Procedure

PLEASE NOTE This is the first of a two part series. Part two with comprehensive and specific options on what to do if you already have a root canal will be posted soon. These two articles are our effort to help save lives not teeth.

By Dr. Lina Garcia

One of the fundamental understandings that supports holistic, biological dentistry is that the dental procedures and materials used in them can affect your whole body, not just your teeth.

In the case of a root canal procedure, it can lead to a number of chronic health problems and even degenerative diseases. Unfortunately, it is very rare for someone in need of dental care to be aware of this.

Although you may be surprised to read this view of root canals, any time the procedure is done there is a real possibility it can endanger your overall health because of the infection and toxicity that can develop in your tooth after the root canal is performed.

The connection between a root canal treated tooth and disease in another area of your body is one the majority of health-care practitioners and their patients are simply unaware of.

The lack of awareness of this connection is puzzling when you consider that in conventional dentistry medicine there is an appreciation of research that has identified a connection between periodontal disease and other health problems, such as heart disease, stroke, respiratory diseases, diabetes, osteoporosis and difficulties during pregnancy.

Periodontal disease is the general label used to describe chronic infection and/or inflammation of the gums and the supporting structures of the teeth. The American Academy of Periodontology actively seeks to educate the public about research that supports what perceptive dentists inevitably recognize: “Infections in the mouth can play havoc elsewhere in the body.”

Periodontal Disease: A Risk Factor for a Root Canal

Periodontal disease has been identified as a potential risk factor for many systemic diseases. However it is not well appreciated that microbes surrounding a periodontally involved tooth can invade it from the apex and damage or kill it.

When this happens, a conventional dentist will recommend a root canal procedure. Tragically, most conventional dental and medical establishments inexplicably disregard the connection between oral microbes associated with root canals and systemic disease.

So, every year, millions of Americans undergo at least one root canal procedure with no awareness of the risk involved to their overall health. The root canal procedure is typically done instead of extracting the diseased, dying or sometimes already dead tooth.

Root canals have been, and continue to be, a conventional, or “standard of care,” procedure done by a dentist or an endodontist. (An endodontist is a dentist who specializes in doing a root canal procedure, which is also called endodontic therapy.)

The root canal procedure is endorsed by the dental establishment as the preferred alternative to extraction. It is a big part of the business of dentistry. Give people what they want — and who wants to lose a tooth? So conventional dentistry offers a procedure that allows patients to keep a problem tooth while conveying confidence there are no risks involved.

But, unfortunately, there are risks.And what all too many dental practitioners don’t realize isthat a root canal treated tooth can be a direct cause of numerous degenerative diseases.

Many Diseases Can Be Related to Root-Canal-Treated Teeth

If you have at least one root canal treated tooth, acting upon the understanding that it can be damaging to your health may help you realize freedom from one of the diseases or ailments listed in the table below.
Arthritis Appendicitis Endocarditis, myocarditis (heart inflammation) Kidney, liver and gallbladder problems
Meningitis Anemia Hardening of the arteries Nervous system breakdowns
Pneumonia Heart lesions Eye infections Cancer

Many people suffer from diseases or ailments that modern medicine says are ofunknown cause. Well, the reality is that root canals are a seriously overlooked cause of many diseases.

More and more holistic-minded dentists, physicians and other practitioners are beginning to realize that many previously “incurable” diseases and ailments, which have no conventionally recognized cause, can sometimes be radically improved or completely resolved by extracting a root-canal tooth (or teeth) and properly cleaning out the tooth socket(s).

A Root Canal Will Leave Dead Tissue in Your Body

On the surface, having a root canal procedure instead of extracting a tooth is very appealing. A tooth is obviously an important part of your body that you want to keep if at all possible. Butit’s more important for you to see your health in a holistic way, so you can avoid losing much more than your tooth It’s silly for us to think of ourselves as a collection of body parts that function independently of each other.

Seeing your health in a holistic way leads to understanding that each and every, part of your body can have an influence on the whole. In cases of intense pain, it may be thought of as a “mercy killing,” but having a root canal can definitely be an effective way to eliminate the pain — kill the tooth and you kill the pain.

The pain is gone because the nerves are gone. However, a much more accurate, no-nonsense way of describing the end result of a root canal is this: It doesn’t “save” the life of the tooth, but it does keep enough of the tooth’s structure intact so that the crowned chewing surface will be functional, and you keep the aesthetic value of the tooth.

So there you are — you are now left with a functional but dead tooth in your mouth that looks good when you smile. But think about this for a moment. Doesn’t it seem unhealthy, and even strange, to leave a dead tooth in your mouth? If any another organ in your body, like your appendix, were dead, it would have to be removed or else very aggressive strains of microbes that nature uses to decompose dead tissue would set in and threaten your life! And something similar happens with a dead tooth, whether it is killed from infection, trauma or the root-canal procedure.

After a root canal is done, the dead tooth, not sometimes, but always becomes an environment conducive to harboring chronic infection and toxicity.Because there is no reliable way, practically speaking, to completely sterilize a root canal treated tooth, (while it is still in a patient’s mouth), it will be a source of infection for the whole bodyuntil it is extracted and the tooth socket is cleaned.

How to Avoid the Root Canal Procedure that You Might Not Even Need

One of my biggest challenges as a Biological Dentist is when a patient cries with regret for agreeing to have a root canal procedure done to a tooth or teeth – a procedure they neither needed nor understood from the perspective of whole body health. Like any part of the body, a tooth can be inflamed, painful, or simply sensitive. If you go to a dentist they will quite often advise you to have a root canal.

But not so fast! Let’s learn and make a wise decision. The table below lists several reasons a tooth can be sensitive or painful but please understand that it there is not enough space in this article to more fully elaborate. The best way to evaluate your specific pain would be with a qualified dental professional.

Clenching or grinding Stress Poor hygiene Referred pain from your heart
Referred muscle pain from temporalis or masseter muscles Lack of sleep Trigeminal neuralgia Sinus headaches
Sugars or processed foods, even fruits Ill-fitting restorations Neuropathic pain Tumors or aneurisms
Hormone changes including perimenopause, menstrual cycles, and changes in testosterone levels Fractures Referral headaches from migraines or cluster headaches that change the blood vessels and nerves of the head Salivary dysfunction

Every single tooth is a little organ, and the same blood and lymphatic fluid that flows to and through your heart and all the other organs and systems in your body also flows to and through your teeth. Additionally, there is a complex system of nerves that connect your teeth to your brain, and every tooth is connected to one of the channels of life-force energy most commonly known as the acupuncture meridians. So, when you see the whole picture, you understand that your teeth are affected by what is going on throughout your body, and, of course, your entire body is affected by what is going on in your teeth.

Unfortunately, we usually do not learn about the oral/systemic health connection and the hidden risks of conventional dental practices until after we have developed at least one chronic health problem conventional practitioners do not know how to resolve. I understand it can be hard to believe that established dental practices that have been around for many decades can be obstacles to your good health because it was a challenge for me as well. All biological dental professionals were once traditionally trained. The move away from that training to encompass a wider view is never easy, but vital to our integrity.

Be Your Own Advocate and Become Educated

Changing things for the better begins with questioning the status quo. It ultimately requires that you make better-informed choices so you do not wind up supporting the dysfunctional aspects of the conventional dental and medical establishments. Every time you accept and pay for a treatment, you are in essence saying, “I support this.” So please, before paying for a root canal procedure, or for that matter, any other procedure, make sure the problem is not somewhere else and that the pain in your tooth will not subside if you properly address that issue.

The surest path to good health is to become educated (at least in a general way) about the different approaches to dentistry and medicine that are available to you before you actually have to make a choice for you or your children. With this in mind, I encourage you to seek out and create your own network of practitioners — family physician, dentist and nutritionist, for starters — who have a holistic understanding of health and appreciate the value of working together as a team to meet the health-care needs of you and your children. While finding and creating your own network of holistic practitioners will take some time, it will be time well spent.

My years of practice have taught me that the best way to prevent disease is to build your health. We all have a self-healing potential, which I refer to as “the Health.” I’m devoted to helping people learn how dental practices caneither improve or damage their health. I want to help you make well-informed choices that support your health in body, mind and spirit. You certainly do have choices to make, especially avoiding unnecessary root canal procedures.

The holistic physician Dr. Thomas Rau, in his comprehensive book, Biological Medicine, says: “The disruptive fields which occur most frequently in the body, causing remote illnesses in other organs, are the teeth. So long as these disruptive factors are not eliminated, the physician will remain unsuccessful in many cases of chronic disease.” Ultimately, the tragic consequence of not acknowledging the connection between our teeth, dental treatments and our overall health is no attention is given to the real cause of — and curative treatment for — many chronic health problems.

Powerful Strategies to Consider Before a Root Canal

When you have pain in your leg, arm, stomach, eyes or any body part, hopefully you are not advised to kill the nerves of the area to shut off the pain. While this is obvious for these body parts, this advice is not obvious, and certainly not routine in your mouth. Most conventional practitioners have accepted the idea of killing a tooth even though it causes a poisonous environment that harbors pathologic bugs and disease. If a tooth is sensitive or hurting, the following are some of my recommendations before agreeing and paying for a root canal procedure:

Ozone therapy Proper oral hygiene Stress management
Nutrition Oil pulling Local support for the tooth such as adjusting an ill-fitting restoration, a splint or mouth guard, decay and more
Digest enzymes Proper sleep Traditional Osteopathic Treatment and support

All the above can buy time for your immune system to recover allowing your tooth to heal. In trying to support and encourage my patients’ own healing capabilities, and based on my studies, I will tell you that, without a doubt, what you are eating and drinking every day has a huge influence on the health of your teeth and gums. Even more, it is essential for us to appreciate that good nutrition contributes to the structure and function of every cell in our bodies.

I want to do all I can to make sure my patients and readers of this article understand the importance of developing the right nutrition habits in order to prevent tooth decay, gum disease and other dental problems. Nutrition can also support you while your tooth is healing from a metabolic, physical or emotional injury. In that respect I firmly agree with Dr. Mercola’s nutrition plan . If you haven’t had a chance to review it, please do as it is completely free and over 100 pages. It is divided into beginner, intermediate, and advanced sections so you can easily customize it for yourself

There is absolutely no question that making a commitment to self-care practices to help to prevent tooth decay in the first place is an example of wisdom in action. Except for a tooth injured by some type of physical trauma, a tooth that has had a root canal procedure, also had some degree of decay.

Prevention is BEST Option for Avoiding Root Canals

To prevent the need for root canal treatments, you must eliminate tooth decay through proper oral hygiene and good nutrition. Proper oral hygiene and regular dental cleanings are preventative measures that help to remove the sticky plaque and calcified deposits that form on the surface of teeth and helps to minimize the impact of many individuals’ nutritionally poor and sugar rich diets. I have learned, and so I teach, that faithfully practicing good nutritional habits is, without a doubt, the most important preventative measure, because tooth decay is a consequence of systemic metabolic disturbance.

As Dr. Weston Price wrote in his book, ‘Nutrition and Physical Degeneration’, “…when teeth are decaying, other things are going wrong in the body”! To achieve optimal oral and total body health, your teeth and the rest of your body needs you to choose high quality foods that are in harmony with your metabolism. It is also absolutely essential to eliminate all sources of refined and processed sugar, white flour products, soft drinks and all other ‘junk’ foods and beverages. The wisdom is actually very simple: give your body what it needs and avoid hurting yourself with what you are eating and drinking!

A wise but simple oral hygiene practice that can be very supportive in helping you to have healthy teeth and gums, is the practice of ‘oil pulling’. This wonderful practice not only has preventive value, but also therapeutic value for teeth and gums. Choosing to keep a dead tooth in your mouth can put you at increased risk of a variety of health problems. So, if a dentist recommends a root canal procedure to “save” your tooth from being pulled, remember to ask yourself, “How will I be affected if I have a dead, chronically infected tooth in my mouth?” Or do I really need this root canal? Perhaps the tooth can heal without the unnecessary root canal procedure.

When I graduated from dental school, I took an oath that to this day encourages me. The oath said in part: “I will strive to advance my profession by seeking new knowledge and by re-examining the ideas and practices of the past.” I hope that oath guides you, as well as me, on this journey toward making choices that will support your health. I hope it will encourage you, your family and the community to help forge a new dental and medical “Paradigm”.

The Breast Cancer Red Flag Most Women Ignore

By Dr. Mercola

For many of you, the hint of spring is on the horizon and the opportunity to finally expose your skin to healthy doses of sunshine is very close. Remember that this is a far better choice than using oral vitamin D, as that is how your body was designed to get healthy vitamin D levels.

There are many reasons to be conscious of vitamin D, but today’s featured study will focus on breast health. A robust and rapidly growing body of research clearly shows that vitamin D is absolutely critical for good health and disease prevention, in part due to the fact that it influences about 10 percent of all your genes.

Just one example of an important gene that vitamin D up-regulates is your ability to fight infections and chronic inflammation. It also produces over 200 anti-microbial peptides, the most important of which is cathelicidin, a naturally occurring broad-spectrum antibiotic.

Recent studies demonstrate how optimizing your vitamin D levels may lower your LDL cholesterol levels and double your chances of surviving breast cancer. Researchers also claim to have discovered a causal link between vitamin D deficiency and autism spectrum disorder.

Vitamin D for Breast Cancer

Since the early 2000s, scientific investigations into the effects of vitamin D have ballooned. By the end of 2012, there were nearly 34,000 published studies on the effects of vitamin D, and there are well over 800 references in the medical literature showing vitamin D’s effectiveness against cancer alone.

According to Carole Baggerly, founder of GrassrootsHealth, as much as 90 percent of ordinary breast cancer may in fact be related to vitamin D deficiency.

Most recently, a meta-analysis of five studies published in the March 2014 issue of Anticancer Research1 found that patients diagnosed with breast cancer who had high vitamin D levels were twice as likely to survive compared to women with low levels.2, 3, 4

The analysis included more than 4,500 breast cancer patients over a nine-year period. The high serum group had an average vitamin D level of 30 nanograms per milliliter (ng/ml). Women in the low serum group averaged 17 ng/ml, which is the average vitamin D level found in American breast cancer patients.5

The study was co-authored by Professor Cedric F. Garland—featured in the 2011 video above—along with other researchers at the San Diego School of Medicine. Funding for the research6 was in part provided by a Congressional allocation to the Penn State Cancer Institute of the Milton S. Hershey Medical Center.

Vitamin D has a number of anticancer effects, including the promotion of cancer cell death, known as apoptosis, and the inhibition of angiogenesis (the growth of blood vessels that feed a tumor). According to Dr. Garland:

“As long as vitamin D receptors were present, tumor growth was prevented and kept from expanding its blood supply. Vitamin D receptors are not lost until a tumor is very advanced. This is the reason for better survival in patients whose vitamin D blood levels are high.”

The researchers urge physicians to make vitamin D monitoring and optimization part of standard breast cancer care, and recommend that breast cancer patients should restore their vitamin D levels to a normal range of 30-80 ng/ml. According to the featured findings, you need at least 30 ng/ml of serum 25-hydroxyvitamin D (25(OH)D) to prevent cancer from spreading. That said, other research suggests you’d be better off with levels as high as 80 ng/ml.

How Much Vitamin D Is Required for Breast Cancer Prevention?

In 2011, Dr. Garland’s team found that a vitamin D level of 50 ng/ml is associated with a 50 percent lower risk of breast cancer.7, 8 (Similarly, a 2007 study published in the American Journal of Preventive Medicine9 concluded that a vitamin D level of more than 33 ng/mL was associated with a 50 percent lower risk of colorectal cancer.)

In the featured video above, GrassrootsHealth founder Carole Baggerly interviews Dr. Garland about those 2011 findings.

At that time, they discovered that in order to achieve protective levels, you have to take far more supplemental vitamin D than previously thought. To reach a minimum protective level of 40 ng/ml of vitamin D, study participants had to take anywhere from 1,000 IUs to as much as 8,000 IUs of vitamin D3 per day—a far cry from the recommended daily allowance of 600 IUs of vitamin D for adults.

The supplemental dose ensuring that 97.5 percent of the study population achieved a serum 25(OH)D of at least 40 ng/mL was 9,600 IU/day. This study also concluded that intake of up to 40,000 IUs per day is unlikely to result in vitamin D toxicity.

It’s important to note, however, that it’s virtually impossible to make a general recommendation on how much vitamin D to take as the amount needed can vary significantly from one individual to another. In essence, you need to regularly monitor your levels, and take whatever amount of vitamin D3 you need to maintain a clinically relevant level.

Eighteen Things you never knew…

1. A good belly laugh can dilate your blood vessels an average of 22% making laughter good for your heart.
2. Aspirin has been linked to ringing in the ears (tinnitus). But 40 mg of ginkgo biloba, 3 times a day may relieve the problem.
3. Freshly brewed chamomile tea can help relieve stubborn flatulence. Adding fennel, peppermint, and ginger can boost its effectiveness.
4. Sleeping pills can spike your risk of dying by more than a third. A low dose of melatonin – 0.1 to 0.3 mg, at night – can improve sleep quality without the drug side effects.
