Osteopathy is the body of medicine that originally used strictly manipulative techniques for correcting somatic abnormalities thought to cause disease and inhibit recovery. ...

Claims made for the benefits of spinal adjustments range from temporary, palliative (pain relieving) effects to long term wellness and preventive care. Some claims are controversial, particularly with regard to indications and health benefits.

An indication is when something is indicated by methods of a reference. ... Joint manipulation is a type of passive movement of a skeletal joint. ...

Spinal adjustment is a variation of a procedure also known as spinal manipulation, and specifically intended to correct vertebral subluxations. Spinal manipulation has documented use as far back as Hippocrates and the ancient Egyptians and was carried through the ages by families of bonesetters. The modern form of spinal manipulation techniques have characteristic biomechanical features, and are usually associated with an audible "popping" sound. There is strong evidence that this sound is the result of a phenomenon known as cavitation. // Spinal manipulation is manipulation of synovial joints in the spinal column. ...

Adjustment/manipulation

The central clinical method that all chiropractors agree on is spinal manipulation or spinal adjustment. Though, the terms "spinal adjustment" and "spinal manipulation" are often used interchangeably by chiropractors in their literature and research,^[1] chiropractors much prefer to use the word "adjustment" to describe the nature of their work.^[2]

Definition

The International Chiropractors Association (ICA) defines a chiropractic adjustment as being “characterized by a specific thrust applied to the vertebra utilizing parts of the vertebra and contiguous structures as levers to directionally correct articular malposition [an undesired positioning of a joint].”^[3] The definition of this procedure describes the use of a load (force) to specific body tissues with therapeutic intent. This ‘load’ is traditionally used by hand, and can vary in its velocity, amplitude, duration, frequency, and body location (Meeker & Haldeman, 2002, p. 218).[2]

Intention

The intention of a chiropractic adjustment is to affect or correct the alignment, motion and/or function of vertebrae. Specifically, they are intended to correct "vertebral subluxations;" the term given to the signs and symptoms that are said to result from abnormal alignment of vertebrae (Meeker & Haldeman, 2002, p. 218).[2] This intention forms the legal and philosophical foundation of the profession, and is even formulated in US Medicare law as "manual manipulation of the spine to correct subluxation."

Adjustment methods

As the chiropractic profession engaged in the pursuit of improving health through adjustments to the nervous system, individual practitioners and institutions proposed and developed various proprietary techniques and methods. While many of these techniques did not endure, hundreds of different approaches remain in chiropractic practice today. Most cite case studies, anecdotal evidence, and patient testimonials as evidence for effectiveness. These techniques include:

• Toggle Drop - this is when the chiropractor, using crossed hands, presses down firmly on a particular area of the spine. Then, with a quick and precise thrust, the chiropractor adjusts the spine. This is done to improve mobility in the vertebral joints.
• Lumbar Roll (aka side posture) - the chiropractor positions the patient on his or her side, then applies a quick and precise manipulative thrust to the misaligned vertebra, returning it to its proper position.
• Release Work - the chiropractor applies gentle pressure using his or her fingertips to separate the vertebrae.
• Table adjustments - The patient lies on a special table with sections that drop down. The chiropractor applies a quick thrust at the same time the section drops. The dropping of the table allows for a lighter adjustment without the twisting positions that can accompany other techniques.
• Instrument adjustments - often the gentlest methods of adjusting the spine. The patient lies on the table face down while the chiropractor uses a spring-loaded activator instrument to perform the adjustment. This technique is often used to perform adjustments on animals as well.
• Manipulation under anesthesia (MUA) - this is performed by a chiropractor certified in this technique in a hospital outpatient setting when the patient is unresponsive to traditional adjustments.

Manipulation under Anesthesia or MUA is spinal manipulation performed while the patient is under general anesthesia. ...

Adjustment techniques

There are many techniques which chiropractors can specialize in and employ in spinal adjustments. Some of the most notable techniques include:

• Activator Methods - uses the Activator Adjusting Instrument instead of by-hand adjustments to give consistent mechanical low-force, high-speed clicks to the body. Utilizes a leg-length analysis to determine segmental aberration.
• Active Release Therapy (Active Release Technique) - soft tissue system/movement based massage technique that treats problems with muscles, tendons, ligaments, fascia and nerves.
• Blair Upper Cervical Technique - an objective upper cervical technique focusing primarily on misalignments in the first bone of the spine (Atlas) as it comes into contact with the head (Occiput).
• Cox Flexion-Distraction - a gentle, non-force adjusting procedure which mixes chiropractic principles with osteopathic principles and utilizes specialized adjusting tables with movable parts.
• Hole-in-one technique - developed by B.J. Palmer. He, at some point, claimed that the "pure, unadulterated & straight" chiropractors should only treat the upper two cervical vertebrae (C1-C2) , which is the cause of most, if not all, disorders by being misaligned.
• Directional Non-Force Technique - utilizes a diagnostic system for subluxation analysis consisting of gentle challenging and a unique leg check allowing the body to indicate the directions of misalignment of structures that are producing nerve interference. A gentle but directionally specific thumb impulse provides a long lasting correction to bony and soft tissue structures.
• Diversified - the classic chiropractic technique, developed by D.D. Palmer, DC. Uses specific manual thrusts focused on restoring normal biomechanical function. Has been developed to adjust extremity joints as well.
• Gonstead Technique - Developed by an engineer enthusiast turned chiropractor, this technique uses a very specific method of analysis by the use of nervoscopes, full spine x-rays and precise adjusting techniques that condemns "torquing" of the spine, which may harm the Intervertebral disc.
• Kale Technique (Specific Chiropractic) - gentle technique which utilizes a special adjusting table that helps adjust and stabilize the upper cervical region surrounding the brain stem.
• Logan Basic Technique - a light touch technique that works to "level the foundation" or sacrum. Its concept employs the use of heel lifts and specific contacts.
• NUCCA Technique - manual method of adjusting the atlas subluxation complex based on 3D x-ray studies which determine the correct line of drive or vector of force.
• Thompson Terminal Point Technique (Thompson Drop-Table Technique) - uses a precision adjusting table with a weighing mechanism which adds only enough tension to hold the patient in the "up" position before the thrust is given.
• Toggle Recoil Technique - a quick thrust and release to the upper cervical vertebra, the recoil is to allow the vertebra to oscillate into its proper position.

Mechanisms and effects

The effects of spinal adjustment vary depending on the method performed. All techniques claim effects similar to other manual therapies, ranging from decreased muscle tension to reduced stress. Studies show that most patients go to chiropractors for musculoskeletal problems: 60% with low back pain, and the rest with head, neck and extremity symptoms (Meeker & Haldeman, 2002, p. 219).[2] Also the article Chiropractic: A profession at the crossroads of mainstream and alternative medicine states that, “chiropractic was to be a revolutionary system of healing based on the premise that neurologic dysfunction caused by ‘impinged’ nerves at the spinal level was the cause of most dis-ease” (Meeker & Haldeman, 2002, p. 218).[2] The mechanisms that are claimed to alter nervous system function and affect overall health are seen as speculative in nature, however, clinical trials have been conducted that include “placebo-controlled comparisons [and] comparisons with other treatments” (Meeker & Haldeman, 2002, p. 220).[2] Out of 43 trials 30 preferred manipulation over the comparisons showing that the benefits of chiropractic can’t be seen as speculative in nature.^{[citation needed]} There are many ways that a chiropractor can choose to help a person. Some of the techniques use adjustments in an effort to restore proper posture and curvatures; confirming that “poor posture and physical injury, including birth trauma, may be common primary causes of illness and can have a direct and significant impact not only on spinal mechanics, but on other bodily functions” (Cooper & McKee, 2003, p. 113).^[4] Whether these effects are placebo related is speculative though. Regardless of the technique used, most emphasize the repetitive use of adjustments over time in an effort to retrain the body's nervous system.

The effects of spinal manipulation have been shown to include: temporary relief of musculoskeletal pain, increased range of joint motion, changes in facet joint kinematics, increased pain tolerance and increased muscle strength (Meeker & Haldeman, 2002, p. 222).[2] Common side effects of spinal manipulative therapy (SMT) are characterized as mild to moderate and may include: local discomfort, headache, tiredness, or radiating discomfort (Meeker & Haldeman, 2002, p. 222).[2]

Safety

The World Health Organization states that when "employed skillfully and appropriately, chiropractic care is safe and effective for the prevention and management of a number of health problems."^[5] As with all interventions, there are risks associated with spinal manipulative therapy (SMT). Common, but unserious side effects include: discomfort, headache, and fatigue which will go away after 24 to 48 hours. Infrequent, but potentially serious side effects include: strokes, spinal disc herniation, vertebral and rib fractures and cauda equine syndrome (Meeker & Haldeman, 2002, p. 222).[2]^[6] // Spinal manipulation is manipulation of synovial joints in the spinal column. ...

A study on the chiropractic spinal adjustment published in the February 2002 issue of the Annals of Internal Medicine reviewed more than 160 reports and studies on chiropractic. With regard to the safety of neck adjustment, it states: "The apparent rarity of these accidental events has made it difficult to assess the magnitude of the complication risk. No serious complication has been noted in more than 73 controlled clinical trials or in any prospectively evaluated case series to date" (Meeker & Haldeman, 2002, p. 222).[2] In a 1993 study, it was concluded that chiropractic treatment of the lumbar spine by side posture manipulation is "both safe and effective" (as cited in Cassidy, Thiel &Kirkaldy, 1994).^[7] The February 2002 issue of the Annals of Internal Medicine estimated that only 1 of every 100 million manipulations have serious side effects.[2] Annals of Internal Medicine (Ann Intern Med; ISSN 0003-4819) is an academic medical journal published by the American College of Physicians (ACP). ...
