Chiropractic
Chiropractic is a form of alternative medicine mostly concerned with the diagnosis and treatment of mechanical disorders of the musculoskeletal system, especially the spine.[1][2] Some proponents, especially those in the field’s early history, have claimed that such disorders affect general health via the nervous system,[2] through vertebral subluxation, claims which are not based on scientific evidence. The main chiropractic treatment technique involves manual therapy, especially spinal manipulation therapy (SMT), manipulations of other joints and soft tissues.[3] Its foundation is at odds with mainstream medicine, and chiropractic is sustained by pseudoscientific ideas such as subluxation and “innate intelligence” that reject science.[4][5][6][7][8] Chiropractors are not medical doctors.[9]
Numerous controlled clinical studies of treatments used by chiropractors have been conducted, with conflicting results.[4] Systematic reviews of this research have not found evidence that chiropractic manipulation is effective, with the possible exception of treatment for back pain.[4] A critical evaluation found that collectively, spinal manipulation was ineffective at treating any condition.[10] Spinal manipulation may be cost-effective for sub-acute or chronic low back pain but the results for acute low back pain were insufficient.[11] The efficacy and cost-effectiveness of maintenance chiropractic care are unknown.[12] There is not sufficient data to establish the safety of chiropractic manipulations.[13] It is frequently associated with mild to moderate adverse effects, with serious or fatal complications in rare cases.[14] There is controversy regarding the degree of risk of vertebral artery dissection, which can lead to stroke and death, from cervical manipulation.[15] Several deaths have been associated with this technique[14] and it has been suggested that the relationship is causative,[16][17] a claim which is disputed by many chiropractors.[17]
Chiropractic is well established in the United States, Canada, and Australia.[18] It overlaps with other manual-therapy professions such as osteopathy and physical therapy.[19] Most who seek chiropractic care do so for low back pain.[20] Back and neck pain are considered the specialties of chiropractic, but many chiropractors treat ailments other than musculoskeletal issues.[4] Many chiropractors describe themselves as primary careproviders,[4][21] but the chiropractic clinical training does not support the requirements to be considered primary care providers,[2] so their role on primary care is limited and disputed.[2][21] Chiropractic has two main groups: “straights”, now the minority, emphasize vitalism, “innate intelligence”, and consider vertebral subluxations to be the cause of all disease; “mixers”, the majority, are more open to mainstream views and conventional medical techniques, such as exercise, massage, and ice therapy.[22]
D. D. Palmer founded chiropractic in the 1890s,[23] after saying he received it from “the other world”,[24] and his son B. J. Palmer helped to expand it in the early 20th century.[23] Throughout its history, chiropractic has been controversial.[25][26] Despite the overwhelming evidence that vaccination is an effective public health intervention, among chiropractors there are significant disagreements over the subject,[27] which has led to negative impacts on both public vaccination and mainstream acceptance of chiropractic.[28] The American Medical Association called chiropractic an “unscientific cult” in 1966[29] and boycotted it until losing an antitrust case in 1987.[21] Chiropractic has had a strong political base and sustained demand for services; in recent decades, it has gained more legitimacy and greater acceptance among conventional physicians and health plans in the United States.[21]
Waco
Waco (/ˈweɪkoʊ/ way-koh) is a city which is the county seat of McLennan County, Texas, United States.[3] It is situated along the Brazos River and I-35, halfway between Dallas and Austin. The city had a 2010 population of 124,805, making it the 22nd-most populous city in the state.[4] The US Census 2015 population estimate is 132,356.[5] The Waco Metropolitan Statistical Area consists of McLennan and Falls Counties, which had a 2010 population of 234,906.[6] Falls County was added to the Waco MSA in 2013. The US Census 2016 population estimate for the Waco MSA is 265,207.[7]
Indigenous peoples occupied areas along the river for thousands of years. In historic times, the area of present-day Waco was occupied by the Wichita Indian tribe known as the “Waco” (Spanish: Hueco or Huaco).
In 1824, Thomas M. Duke was sent to explore the area after the Waco people tried to defend themselves and their lands from settlers. His report to Stephen F. Austin, described the Waco village:
After further violence due to settler incursion, Austin halted an attempt to destroy their village in retaliation. In 1825, he made a treaty with them. The Waco were eventually pushed out of the region, settling north near present-day Fort Worth. In 1872, they were forced onto a reservation in Oklahoma with other Wichita tribes. In 1902, the Waco received allotments of land and became official US citizens. Neil McLennan settled in an area near the South Bosque River in 1838.[8] Jacob De Cordovabought McLennan’s property[9] and hired a former Texas Ranger and surveyor named George B. Erath to inspect the area.[10]In 1849, Erath designed the first block of the city. Property owners wanted to name the city Lamartine, but Erath convinced them to name the area Waco Village, after the Indians who had lived there.[11] In March 1849, Shapley Ross built the first house in Waco, a double-log cabin, on a bluff overlooking the springs. His daughter Kate was the first settler child to be born in Waco.[12]
