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]
Phoenixville
Phoenixville is a borough in Chester County, Pennsylvania, United States, 28 miles (45 km) northwest of Philadelphia, at the junction of French Creek with the Schuylkill River. It is located in the Philadelphia Metro Area. The population is 16,440 as of the 2010 Census.[3]
Originally called Manavon, Phoenixville was settled in 1732 and incorporated as a borough in 1849. In its industrial heyday early in the twentieth century, it was an important manufacturing center and it was the site of great iron and steel mills such as the Phoenix Iron Works, boiler works, silk mill, underwear and hosiery factories, a match factory, and the famous (and now highly collectible) Etruscan majolica pottery. Like many American towns and cities, Phoenixville owes its growth to its waterways. It is not only situated on the broad Schuylkill River, a historic thoroughfare to Native Americans and early settlers alike, but it is bisected by the fast-flowing French Creek, which was quickly harnessed for water power.
Much of this history was recognized by the creation of the Phoenixville Historic District, the largest National Register of Historic Places site in Chester County. The Black Rock Bridge, Gay Street School, and Schuylkill Navigation Canal, Oakes Reach Section are also listed on the National Register of Historic Places.[4]
