Chiropractic

Chiropractic is a licensed healthcare profession focused on the diagnosis, treatment, and prevention of musculoskeletal disorders, with particular emphasis on the spine. Chiropractors use hands-on spinal manipulation and adjustment techniques to restore proper joint mobility, reduce pain, and support the body's natural capacity for function and recovery. As a regulated healthcare discipline in the United States, chiropractic care is delivered by doctors of chiropractic (DCs) who complete graduate-level clinical training and are licensed in all 50 states.

At its core, chiropractic operates on the principle that structural alignment of the spine and musculoskeletal system plays an important role in overall health and nerve function. When joints become restricted or misaligned — what chiropractors traditionally refer to as subluxations — surrounding muscles, nerves, and tissues may be affected. Adjustments aim to restore movement, reduce mechanical stress, and support the nervous system's ability to communicate effectively with the rest of the body.

Beyond spinal manipulation, modern chiropractic practice often incorporates complementary approaches such as soft tissue therapy, therapeutic exercise, postural rehabilitation, and lifestyle counseling. Many chiropractors collaborate with primary care physicians, physical therapists, and other health professionals as part of an integrative care model. Chiropractic is widely regarded as one of the more evidence-informed complementary disciplines, and it is commonly covered by health insurance plans for musculoskeletal conditions in the United States.

Chiropractic was formally founded in 1895 by Daniel David Palmer in Davenport, Iowa, who performed what is widely cited as the first modern chiropractic adjustment. Palmer theorized that misalignments of the spine — which he called subluxations — interfered with the body's innate intelligence and vital nerve energy, contributing to disease. His son, Bartlett Joshua Palmer, later expanded and systematized the profession, helping establish chiropractic colleges and licensing frameworks in the early 20th century.

The roots of spinal manipulation itself are far older, with historical references to bone-setting and spinal manipulation appearing in ancient Greek, Chinese, and Egyptian texts. Indigenous healing traditions across multiple cultures also incorporated forms of manual therapy to address pain and mobility issues. Over the course of the 20th century, chiropractic evolved significantly from its vitalistic origins toward a more evidence-based, musculoskeletal-focused model of care. Today, the profession is licensed, regulated, and increasingly integrated into mainstream healthcare settings, though philosophical diversity still exists within the field regarding the scope and purpose of chiropractic treatment.
