The Henderson Center was founded in 1985 as The Henderson Center Chiropractic Clinic in King of Prussia, Montgomery County, Pennsylvania, but was strictly a chiropractic clinic until 1993, when Dr. M Jonathan Garzillo, a chiropractor, joined the Center. Since then, the Center has expanded beyond just chiropractic to become a multi-specialty pain management practice, incorporating massage therapies, shiatsu therapy and chiropractic care. Dr. Garzillo also brought a simple philosophy to the Henderson Center. Instead of trying to prolong care, the Center works to relieve patients of their pain in the shortest time possible. I ...

Chiropractic has seen considerable controversy and criticism.[25][26] Although D.D. and B.J. were "straight" and disdained the use of instruments, some early chiropractors, whom B.J. scornfully called "mixers", advocated the use of instruments.[23] In 1910, B.J. changed course and endorsed X-rays as necessary for diagnosis; this resulted in a significant exodus from the Palmer School of the more conservative faculty and students.[23] The mixer camp grew until by 1924 B.J. estimated that only 3,000 of the U.S.'s 25,000 chiropractors remained straight.[23] That year, B.J.'s invention and promotion of the neurocalometer, a temperature-sensing device, was highly controversial among B.J.'s fellow straights. By the 1930s, chiropractic was the largest alternative healing profession in the U.S.[23]
There are several schools of chiropractic adjustive techniques, although most chiropractors mix techniques from several schools. The following adjustive procedures were received by more than 10% of patients of licensed U.S. chiropractors in a 2003 survey:[73] Diversified technique (full-spine manipulation, employing various techniques), extremity adjusting, Activator technique (which uses a spring-loaded tool to deliver precise adjustments to the spine), Thompson Technique (which relies on a drop table and detailed procedural protocols), Gonstead (which emphasizes evaluating the spine along with specific adjustment that avoids rotational vectors), Cox/flexion-distraction (a gentle, low-force adjusting procedure which mixes chiropractic with osteopathic principles and utilizes specialized adjusting tables with movable parts), adjustive instrument, Sacro-Occipital Technique (which models the spine as a torsion bar), Nimmo Receptor-Tonus Technique, applied kinesiology (which emphasises "muscle testing" as a diagnostic tool), and cranial.[76] Chiropractic biophysics technique uses inverse functions of rotations during spinal manipulation.[77] Koren Specific Technique (KST) may use their hands, or they may use an electric device known as an "ArthroStim" for assessment and spinal manipulations.[78] Insurers in the US and UK that cover other chiropractic techniques exclude KST from coverage because they consider it to be "experimental and investigational".[78][79][80][81] Medicine-assisted manipulation, such as manipulation under anesthesia, involves sedation or local anesthetic and is done by a team that includes an anesthesiologist; a 2008 systematic review did not find enough evidence to make recommendations about its use for chronic low back pain.[82]
Health professionals may know better in theory, but often underestimate how easily patients are alarmed by hard evidence of spinal degeneration. To the average person, if something like that shows up on a scan, it’s like proof: it has got to hurt. But the evidence clearly contradicts that! Pain has many possible minor causes; degeneration is often painless and rarely serious even when it is causing trouble. BACK TO TEXT
Dr. Daniel Lee Grotzinger was born in St. Marys, PA on July 7, 1948. He grew up with a deep interest in music and aviation. In his senior year he applied to both the Air Force Academy and for a Pitt university music scholarship. Neither came through. A semester was spent at St. Vincent college in Latrobe, PA studying for the Catholic priesthood before deciding to enlist in the USAF during the Viet-Nam war. He specialized in the radar systems for the B-58 and B-52. After four years of service he was discharged with spinal injuries. Several years of severe back pain with sciatica, with no relief from the usual medical methods lead to Dan trying chiropractic upon the advise of a church friend. In three visits the severe bilateral sciatic pain was resolved. Again, he applied to music school but found there was a long waiting list. Because of the tremendous help chiropractic had given him he began to think there must be a lot of others who have gone through what he did and could use the same kind of help. After several prayer sessions he received a very clear witness that this should be his life calling.
Utilization of chiropractic care is sensitive to the costs incurred by the co-payment by the patient.[1] The use of chiropractic declined from 9.9% of U.S. adults in 1997 to 7.4% in 2002; this was the largest relative decrease among CAM professions, which overall had a stable use rate.[212] As of 2007 7% of the U.S. population is being reached by chiropractic.[213] They were the third largest profession in the US in 2002, following doctors and dentists.[214] Employment of U.S. chiropractors was expected to increase 14% between 2006 and 2016, faster than the average for all occupations.[185]
Most patients don't realize how much education chiropractors in Cincinnati have. Chiropractors are held to some of the most intense educational standards of any health field. In fact their education standards are very comparable to that of a medical doctor. After completing a strong emphasis of basic sciences in college, chiropractors attend a four year chiropractic college. This means that chiropractors are primary care physicians. 
Chiropractic works by making carefully placed adjustments to realign your spine. These adjustments allow the muscle tissues to properly support the spine and vital neurological processes that occur within it. When the spine is able to function without interference, the body is better able to facilitate healing, thereby relieving pain and restoring health in a variety of ways.

Spinal manipulation, which chiropractors call "spinal adjustment" or "chiropractic adjustment", is the most common treatment used in chiropractic care.[73] Spinal manipulation is a passive manual maneuver during which a three-joint complex is taken past the normal range of movement, but not so far as to dislocate or damage the joint.[74] Its defining factor is a dynamic thrust, which is a sudden force that causes an audible release and attempts to increase a joint's range of motion.[74] High-velocity, low-amplitude spinal manipulation (HVLA-SM) thrusts have physiological effects that signal neural discharge from paraspinal muscle tissues, depending on duration and amplitude of the thrust are factors of the degree in paraspinal muscle spindles activation.[75] Clinical skill in employing HVLA-SM thrusts depends on the ability of the practitioner to handle the duration and magnitude of the load.[75] More generally, spinal manipulative therapy (SMT) describes techniques where the hands are used to manipulate, massage, mobilize, adjust, stimulate, apply traction to, or otherwise influence the spine and related tissues.[74]

Twenty‐six to 71% of the adult population can recall experiencing an episode of neck pain or stiffness in their lifetime. Neck pain is more common in females than in males, with rates reported as high as 77.8%. The natural history is unclear. Neck pain has a costly impact on society because of visits to healthcare providers, sick leave, disability and loss of productivity. There are a number of treatments available for neck pain, one of which is mechanical traction.


As with so many things, when it comes to neck pain, an ounce of prevention may be worth a pound of cure. It's true that some causes of neck pain, such as age-related wear and tear, are not under your control. On the other hand, there are many things you can do to minimize your risk. One place to start is to look at how you sleep and what effect this may have on neck pain.
Neck injuries can occur during motor vehicle accidents, other traumatic events or sports. Symptoms of these injuries include neck stiffness, shoulder or arm pain, headache, facial pain and dizziness. Pain from a motor vehicle injury may be caused by tears in muscles or injuries to the joints between vertebrae. Other causes of pain are ligament rupture or damage to a disc. Conservative treatment of these injuries includes pain medication, bed rest, reduction of physical activity and physical therapy.
Low back pain. A 2013 Cochrane review found very low to moderate evidence that SMT was no more effective than inert interventions, sham SMT or as an adjunct therapy for acute low back pain.[94] The same review found that SMT appears to be no better than other recommended therapies.[94] A 2016 review found moderate evidence indicating that chiropractic care seems to be effective as physical therapy for low back pain.[95] A 2012 overview of systematic reviews found that collectively, SM failed to show it is an effective intervention for pain.[96] A 2011 Cochrane review found strong evidence that suggests there is no clinically meaningful difference between SMT and other treatments for reducing pain and improving function for chronic low back pain.[97] A 2010 Cochrane review found no current evidence to support or refute a clinically significant difference between the effects of combined chiropractic interventions and other interventions for chronic or mixed duration low back pain.[98] A 2010 systematic review found that most studies suggest SMT achieves equivalent or superior improvement in pain and function when compared with other commonly used interventions for short, intermediate, and long-term follow-up.[99] Specific guidelines concerning the treatment of nonspecific (i.e., unknown cause) low back pain are inconsistent between countries.[100]
Most people believe that chiropractors treat back pain. That is a true, but there is so much more that chiropractic care can achieve. Because chiropractors help to remove pressure from the nervous system, they can also influence many other conditions. It is common to hear chiropractic patients say that they came in for back pain and their headaches got better.
Sharp neck pain is not in itself a red flag. Believe it or not there is no common worrisome cause of neck pain that is indicated by a sharp quality. In fact, oddly, sharp pains are actually a bit reassuring, despite how they feel. In isolation — with no other obvious problem — they usually indicate that you just have a temporary, minor source of irritation in the cervical spine. Serious causes of neck pain like infections, tumours, and spinal cord problems tend grind you down with throbbing pains, not “stab” you.

We achieve these results not with potent drugs or harmful muscle relaxers but with spinal decompression therapy that uses intermittent spinal traction to take stress off injured vertebral joints while concurrently hydrating your discs, Chiropractic Adjustments to facilitate proper motion in the joints, electrical stimulation to reduce muscular and nerve pain in localized areas and much more.

Chiropractic's origins lie in the folk medicine of bonesetting,[4] and as it evolved it incorporated vitalism, spiritual inspiration and rationalism.[30] Its early philosophy was based on deduction from irrefutable doctrine, which helped distinguish chiropractic from medicine, provided it with legal and political defenses against claims of practicing medicine without a license, and allowed chiropractors to establish themselves as an autonomous profession.[30] This "straight" philosophy, taught to generations of chiropractors, rejects the inferential reasoning of the scientific method,[30] and relies on deductions from vitalistic first principles rather than on the materialism of science.[31] However, most practitioners tend to incorporate scientific research into chiropractic,[30] and most practitioners are "mixers" who attempt to combine the materialistic reductionism of science with the metaphysics of their predecessors and with the holistic paradigm of wellness.[31] A 2008 commentary proposed that chiropractic actively divorce itself from the straight philosophy as part of a campaign to eliminate untestable dogma and engage in critical thinking and evidence-based research.[32]

Mixer chiropractors "mix" diagnostic and treatment approaches from chiropractic, medical and/or osteopathic viewpoints and make up the majority of chiropractors.[22] Unlike straight chiropractors, mixers believe subluxation is one of many causes of disease, and hence they tend to be open to mainstream medicine.[22] Many of them incorporate mainstream medical diagnostics and employ conventional treatments including techniques of physical therapy such as exercise, stretching, massage, ice packs, electrical muscle stimulation, therapeutic ultrasound, and moist heat.[22] Some mixers also use techniques from alternative medicine, including nutritional supplements, acupuncture, homeopathy, herbal remedies, and biofeedback.[22]

Our office is not only about adjusting your spine. I am certified in treating a wide range of conditions and focus on muscles and soft tissue that may need to be lengthened or strengthened. I am certified in soft tissue techniques called Trigenics and Instrument Assisted Soft Tissue Mobilization (Scraping). We are getting better and faster results since implementing both techniques. I have extensive training with the Advanced Functional Neurology Institute. All of these trainings have allowed me to treat conditions such as Peripheral Neuropathy, bone on bone degenerative knees and rotator cuff conditions/Frozen Shoulder, among others.
Other. A 2012 systematic review found insufficient low bias evidence to support the use of spinal manipulation as a therapy for the treatment of hypertension.[120] A 2011 systematic review found moderate evidence to support the use of manual therapy for cervicogenic dizziness.[121] There is very weak evidence for chiropractic care for adult scoliosis (curved or rotated spine)[122] and no scientific data for idiopathic adolescent scoliosis.[123] A 2007 systematic review found that few studies of chiropractic care for nonmusculoskeletal conditions are available, and they are typically not of high quality; it also found that the entire clinical encounter of chiropractic care (as opposed to just SM) provides benefit to patients with cervicogenic dizziness, and that the evidence from reviews is negative, or too weak to draw conclusions, for a wide variety of other nonmusculoskeletal conditions, including ADHD/learning disabilities, dizziness, high blood pressure, and vision conditions.[124] Other reviews have found no evidence of significant benefit for asthma,[125][126] baby colic,[127][128] bedwetting,[129] carpal tunnel syndrome,[130] fibromyalgia,[131] gastrointestinal disorders,[132] kinetic imbalance due to suboccipital strain (KISS) in infants,[127][133] menstrual cramps,[134] insomnia,[135] postmenopausal symptoms,[135] or pelvic and back pain during pregnancy.[136] As there is no evidence of effectiveness or safety for cervical manipulation for baby colic, it is not endorsed.[137]

There are several different surgical procedures which can be utilized, the choice of which is influenced by the severity of each case. In a small percentage of patients, spinal instability may require that spinal fusion be performed, a decision that is generally determined prior to surgery. Spinal fusion is an operation that creates a solid union between two or more vertebrae. Various devices (like screws or plates) may be used to enhance fusion and support unstable areas of the cervical spine. This procedure may assist in strengthening and stabilizing the spine and may thereby help to alleviate severe and chronic neck pain.
"Physiologists divide nerve-fibers, which form the nerves, into two classes, afferent and efferent. Impressions are made on the peripheral afferent fiber-endings; these create sensations that are transmitted to the center of the nervous system. Efferent nerve-fibers carry impulses out from the center to their endings. Most of these go to muscles and are therefore called motor impulses; some are secretory and enter glands; a portion are inhibitory, their function being to restrain secretion. Thus, nerves carry impulses outward and sensations inward. The activity of these nerves, or rather their fibers, may become excited or allayed by impingement, the result being a modification of functionality – too much or not enough action – which is disease."[42]
Your neck is a complex interlocking structure consisting of bones, joints, nerves, muscles, tendons and ligaments. Its main job is to hold up the weight of your head which, at around 5 kilograms, is no mean task. Add to this the requirement that the head must be able to move from side to side and up and down (and do these simultaneously), plus the fact that the neck has to form a conduit for the spinal cord, carry blood vessels to and from the head, and contain passageways for air and food, and you have quite a complex feat of engineering. No wonder then that our necks cause us pain and discomfort, not only on occasion, but for some people in an ongoing fashion.The main physical structures in the neck are the seven interlocking vertebrae. They are called the cervical vertebrae, numbered C1 through to C7. C1, also known as the atlas, is the closest one to your head, followed by C2, which is also known as the axis. Each vertebra is connected to the next by facet joints, and between the vertebrae are intervertebral discs — rubbery cushions made mostly of cartilage that act as shock-absorbers.When should I seek immediate medical treatment for neck pain?Severe neck pain that occurs after a neck injury can be a serious problem, and you should see your doctor immediately. Also, if you have problems with neck pain and experience symptoms such as loss of bladder or bowel control, shooting pains, numbness, tingling, or weakness in the arms or legs, especially if these symptoms come on suddenly or get worse quickly, you should see your doctor straight away.Neck pain and stiffness that’s associated with headache and fever can be a sign of meningitis (an infection of the membranes surrounding your brain and spinal cord). Meningitis is a serious disease, and you should seek immediate medical treatment if you or your child are experiencing these symptoms.Symptoms of neck painSymptoms of neck pain and the sensations you feel can help your doctor to diagnose the cause. Here are some symptoms.Muscle spasmA spasm is a sudden, powerful, involuntary contraction of muscles. The muscles feel painful, stiff and knotted. If you have neck muscle spasms, you may not be able to move your neck — sometimes people call it a crick in the neck. Your doctor or physiotherapist may call it acute torticollis or wry neck.Muscle acheThe neck muscles are sore and may have hard knots (trigger points) that are tender to touch. Pain is often felt up the middle of the back of the neck, or it may ache on one side only.StiffnessThe neck muscles are tight and if you spend too long in one position they feel even tighter. Neck stiffness can make it difficult or painful to move your neck.Nerve painPain from the neck can radiate down the arms, and sometimes, the legs. You may feel a sensation of pins and needles or tingling in your arms, which can be accompanied by numbness, burning or weakness. This pain is typically worse at night.HeadachesHeadaches are common in conjunction with neck problems. They are usually a dull aching type of headache, rather than sharp pain. While the headaches are often felt at the back of the head, the pain may also radiate to the sides, and even the front of the head.Reduced range of motionIf you can’t turn your head to the side to the same degree towards each shoulder, or you feel limited in how far forward you can lower your head to your chest, or how far you can tilt your head back, you may have reduced range of motion. Your doctor will be able to test this.Common causes of neck painWhiplashThis commonly follows a car accident in which the person’s car is hit from behind while it is stationary or slowing down. The person’s head is first thrown backwards and then when their body stops moving, the head is thrust forward. This type of injury can strain your neck muscles and cause ligaments in the neck to stretch or tear.The pain from whiplash, which is usually worse with movement, does not always start immediately — it may take several days to come on. Neck pain and stiffness may be accompanied by muscle spasm, dizziness, headaches, nerve pain and shoulder pain.Muscle strainOngoing overuse of your neck muscles (which can be caused by a poor neck position during everyday activities, particularly computer work) can trigger neck muscle strain, causing chronic neck pain and stiffness. The pain is often worse with movement and may be associated with headaches, muscle spasms and restriction of neck movements.Degenerative disc diseaseAs we grow older, the soft gelatinous centre of the shock-absorbing discs in our spines dries out. This causes the discs to become narrowed, and the distance between the vertebrae to decrease.Herniated discIf the tough outside layer of one of the cervical discs tears, the soft gelatinous centre may bulge outwards — this is known as a herniated disc. Herniated discs can put pressure on nerve roots as they leave the spinal cord, causing pain in the neck as well as pain, numbness and weakness in the arms.Cervical spondylosisThis degenerative condition of the cervical spine is due to normal ageing and wear and tear on the cervical discs and the vertebrae. It is also known as cervical osteoarthritis, and is more common among older people.The development of bone spurs often accompanies this degeneration of the spine. Bone spurs, also known as osteophytes, are small outgrowths of bone tissue that are formed when the cartilage covering bone is worn away and bone starts to rub on adjacent bone. The bone spur is the body’s attempt to protect the bone surface. Unfortunately, the bone spur can sometimes pinch or press upon the nerve roots as they leave the spinal canal.Symptoms associated with cervical spondylosis include neck pain and stiffness that often improves with rest. The pain may radiate to the shoulders or between the shoulder blades. If there is nerve root compression, there may be numbness, pain or weakness in the arms.Cervical spinal canal stenosisDegenerative changes in the vertebrae can lead to narrowing of the canal in which your spinal cord lies — this is known as cervical spinal canal stenosis. As the canal becomes narrower, it can put pressure on the spinal cord. The associated neck pain is usually worse with activity, and may radiate to the arms or legs. Arm or leg weakness can also occur. Sometimes people with cervical spinal canal stenosis have no symptoms. Occasionally, it may give rise to Lhermitte's sign — an electric shock-like feeling down the body when the neck is bent forward.Tests and diagnosisYour doctor may be able to determine the cause of your neck pain from your history and physical examination, but sometimes tests such as X-rays, MRI scans and CT scans are required to find the exact cause of your symptoms. These scans can assess the spine and be used to show disc problems, spinal cord problems or compression of your nerve roots.Sometimes doctors will order electromyography (EMG) or nerve conduction studies — tests that evaluate the electrical activity in nerves and muscles to help determine if there is any nerve damage related to your neck problems.It can be difficult to identify the precise source of neck pain even after investigations. Generally, X-ray abnormalities do not correlate well with pain. Some people have severe spondylosis on X-rays, but have no pain. The key thing that your doctor should be able to tell is if the pain is involving pressure on the nerve roots or spinal cord. Last Reviewed: 18 December 2012
Once your history is gathered, the chiropractor may complete a physical exam, or they may begin treatment. This may be a manual spinal manipulation, or the chiropractor may use various chiropractic instruments. After your adjustment is complete, the chiropractor will recommend a schedule of follow-up visits. The number of visits will depend on your current health condition, how much pain you’re in, and what other therapies you’re using to treat your pain. Chiropractic care is always best done in addition to other pain management treatments, such as physical therapy, medication, or pain-reducing injections.
One of the most common questions that people ask is around the safety of chiropractic care. So, how safe is it? According to the American Chiropractic Association, “Chiropractic is widely recognized as one of the safest drug-free, non-invasive therapies available for the treatment of back pain, neck pain, joint pain of the arms or legs, headaches, and other neuromusculoskeletal complaints.” While chiropractic is considered a safe complementary therapy, there can be some potential side effects, like soreness following a spinal manipulation.
