Chiropractic treatment strives to alleviate lower back pain (LBP) by correcting the position of misaligned, or subluxated, vertebra and joints with a series of high-velocity, low-amplitude, manually delivered thrusts. Chiropractic care includes spinal manipulation, spinal-adjusting techniques (e.g., mobilization), spinal manipulation or adjustment in conjunction with the application of physical modalities such as applications of heat or cold therapy, ultrasound (US), and electrical muscle stimulation (EMS), instruction in strengthening and flexibility exercises, and instruction in proper back care.
