Which practice is based on the belief that pressure on nerves leaving the spinal column causes pain and/or dysfunction of the body part served by that nerve?

• A. Chiropractic
• B. Osteopathy
• C. Acupuncture
• D. Physical therapy

Answer: (A)

Chiropractic care centers on spinal alignment and its impact on nerve signaling. It holds that pressure or misalignment of vertebrae can press on nerves as they exit the spinal column, causing pain or dysfunction in the body region served by those nerves. Practitioners use spinal adjustments to restore proper alignment and relieve this nerve interference, aiming to improve nerve communication and reduce symptoms.

Other approaches work differently. Osteopathy also uses manual techniques but with a broader focus on how the musculoskeletal system interacts with the whole body. Acupuncture targets energy flow along meridians rather than mechanical nerve compression. Physical therapy emphasizes learning targeted exercises and modalities to restore movement, strength, and function rather than correcting spinal nerve pressure.
