Chiropractors often argue that this education is as good as or better than medical physicians', but most chiropractic training is confined to classrooms with much time spent learning theory, adjustment, and marketing. The fourth year of chiropractic education persistently showed the highest stress levels. Every student, irrespective of year, experienced different ranges of stress when studying. The chiropractic leaders and colleges have had internal struggles. Rather than cooperation, there has been infighting between different factions. A number of actions were posturing due to the confidential nature of the chiropractic colleges in an attempt to enroll students.[clarification needed]
There is no good evidence that chiropractic is effective for the treatment of any medical condition, except perhaps for certain kinds of back pain. Generally, the research carried out into the effectiveness of chiropractic has been of poor quality. Numerous controlled clinical studies of treatments used by chiropractors have been conducted, with conflicting results. Research published by chiropractors is distinctly biased. For reviews of SM for back pain chiropractic authors tend to have positive conclusions, while others did not show any effectiveness.
Spinal manipulation is associated with frequent, mild and temporary adverse effects, including new or worsening pain or stiffness in the affected region. They have been estimated to occur in 33% to 61% of patients, and frequently occur within an hour of treatment and disappear within 24 to 48 hours; adverse reactions appear to be more common following manipulation than mobilization. The most frequently stated adverse effects are mild headache, soreness, and briefly elevated pain fatigue. Chiropractic is correlated with a very high incidence of minor adverse effects. Chiropractic are more commonly associated with serious related adverse effects than other professionals following manipulation. Rarely, spinal manipulation, particularly on the upper spine, can also result in complications that can lead to permanent disability or death; these can occur in adults and children. There is a case of a three-month-old dying following manipulation of the neck area. Estimates vary widely for the incidence of these complications, and the actual incidence is unknown, due to high levels of underreporting and to the difficulty of linking manipulation to adverse effects such as stroke, which is a particular concern. Adverse effects are poorly reported in recent studies investigating chiropractic manipulations. A 2016 systematic review concludes that the level of reporting is unsuitable and unacceptable. Reports of serious adverse events have occurred, resulting from spinal manipulation therapy of the lumbopelvic region. Estimates for serious adverse events vary from 5 strokes per 100,000 manipulations to 1.46 serious adverse events per 10 million manipulations and 2.68 deaths per 10 million manipulations, though it was determined that there was inadequate data to be conclusive. Several case reports show temporal associations between interventions and potentially serious complications. The published medical literature contains reports of 26 deaths since 1934 following chiropractic manipulations and many more seem to remain unpublished.
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.
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.
The treatment plan may involve one or more manual adjustments in which the doctor manipulates the joints, using a controlled, sudden force to improve range and quality of motion. Many chiropractors also incorporate nutritional counseling and exercise/rehabilitation into the treatment plan. The goals of chiropractic care include the restoration of function and prevention of injury in addition to back pain relief.
