The term "adjustment" refers to the specific manipulation chiropractors apply to vertebrae that have abnormal movement patterns or fail to function normally. The objective of the chiropractic treatment is to reduce the subluxation, which results in an increased range of motion, reduced nerve irritability and improved function.
The adjustment made by the chiropractor consists of a high velocity, short lever arm thrust applied to a vertebra, which is often accompanied by an audible release of gas (joint cavitation). The audible sound is caused by the release of oxygen, nitrogen, and carbon dioxide, which releases joint pressure (cavitation). The sensation is usually relieving, though minor discomfort has been reported (that usually lasts for only a short time duration) if the surrounding muscles are in spasm or the patient tenses up during the chiropractic procedure.
There are times when joint cavitation or cracking does not occur and this is often due to either significant muscle splinting or the patient may not be adequately relaxed during the chiropractic procedure. At times like this, it is sometimes best for the chiropractor to apply ice, have the patient rest, or do electrical stimulationand massage prior to attempting spinal manipulation.
Cox Flexion Distraction Technique
THE RESEARCH SAYS...
The Biomechanics Study
Federally Funded Research has thus far proven the following about Cox® Flexion Distraction:
Reduces intradiscal pressures to a -192 mm Hg
Increases intradiscal height
Increases foraminal size up to 28% (more room for nerve roots & spinal cord)
The Latest Clinical Outcomes Study
European Spine Journal reports on a comparison study of flexion-distraction to medical conservative active-exercise therapy. Patients, including those with radiculopathy, did significantly better with flexion-distraction.
CLINICAL APPLICATION IS...
The following is presented as a general overview of the treatment.
Cox® Technic is DOCTOR-APPLIED, DOCTOR-CONTROLLED, HANDS-ON, SPECIFIC CONTACT, PATIENT-FOCUSED care. During a treatment on this instrument, the patient lies prone while the treating physician concentrates on one vertebral motion segment at a time. The goal is to reduce stenotic effects by dropping intradiscal pressure to allow disc reduction, increasing the size of the intervertebral foramen, and lowering pressure on the dorsal root ganglion and the exiting nerve roots. While concentrating on the low back, the doctor may use the instrument's caudal (the part the legs lie on) section to allow lateral and circular motion which returns normal motion to the spinal segments with reduced pain.
After undergoing a thorough examination which leads the doctor to a specific diagnosis of the spine condition to be treated, the patient lies prone (face-down) on a specially-designed table. Tolerance testing is performed prior to the application of Cox® Technic to be sure there is no aggravation of the condition.
The Lumbar Spine Adjustment
The doctor will hold a spinous process (the back part of the vertebra that feels like a "bump" on your spine) to isolate a single segment for treatment. The distraction manipulation is applied manually by the doctor to the patient's low back at the level(s) of the spine to be treated or that are painful. The doctor controls all motion and notes the spine's response to treatment. Treating conditions, there are three sets of distraction motions. Between each set, the doctor allows the area to "rest" and massages trigger points and muscles to further reduce spasm and increase circulation. (circumduction). All movements are slow and to tolerance.
The late Larry Webster, D.C., Founder of the International Chiropractic Pediatric Association(ICPA), developed a specific chiropractic analysis and adjustment which enables chiropractors to establish balance in the pregnant woman’s pelvis and reduce undue stress to her uterus and supporting ligaments. This balanced state in the pelvis has been clinically shown to allow for optimal fetal positioning. The technique is known as the Webster Technique.
The Webster technique is a specific chiropractic analysis and diversified adjustment. The goal of the adjustment is to reduce the effects of sacral subluxation/SI joint dysfunction. In so doing neuro-biomechanical function in the pelvis is improved.
It is considered normal by some for a baby to present breech until the third trimester. Most birth practitioners are not concerned with breech presentations until a patient is 37 weeks along. Approximately 4% of all pregnancies result in a breech presentation.
The Journal of Manipulative and Physiological Therapeutics reported in the July/August 2002 issue an 82% success rate of babies turning vertex when doctors of chiropractic used the Webster Technique. Further, the results from the study suggest that it may be beneficial to perform the Webster Technique as soon as the 8th month of pregnancy when a woman has a breech presentation.
