Which of the following is a common technique used in chiropractic treatment?

Joint manipulation is a common technique used in chiropractic treatment, which involves applying controlled force to spinal joints. This technique is fundamental to chiropractic philosophy and practice, aimed at restoring proper movement and alignment of the spine, enhancing function, and alleviating pain.

Chiropractors utilize various forms of joint manipulation, often referred to as spinal adjustments, to address musculoskeletal issues and improve the overall health of the nervous system. By correcting misalignments, chiropractors aim to remove interference in the nervous system, allowing for improved communication between the brain and body.

In contrast, other options provided, such as bloodletting, radiation therapy, and homeopathy, are not standard practices in chiropractic care. Bloodletting is an outdated medical practice with no relevance to chiropractic treatment. Radiation therapy is a method used primarily in oncology and is not applicable to the chiropractic field. Homeopathy, while a form of alternative medicine, operates on a different set of principles and is not a technique employed by chiropractors for manipulating joints.
