Welcome to the Upper West Side Chiropractors section containing UWS chiropractors in 10023, 10024, 10025, 10026 and 10027 zip codes. Chiropractors perform a hands-on therapy based on the theory that many medical disorders (especially disorders of the nervous system) may be caused by dislocations in the spine (vertebral subluxations). Chiropractic medicine originated in the late 1800s in the United States. About 12% to 15% of the population of the United States receives treatment from chiropractors. Chiropractic treatments usually involve adjusting the joints and bones in a person's spine using twisting, pulling, or pushing movements. Some chiropractors use heat, electrical stimulation, or ultrasound to help relax the person's muscles before doing a spinal adjustment. The primary theory behind chiropractic therapy is to help the body heal itself by correcting dislocation of the joints, particularly the bones of the spine (vertebrae).
