Chiropractors can perform which of the following according to the scope of practice?

The scope of practice for chiropractors primarily includes normal chiropractic office procedures, which encompass a range of activities related to patient care within the chiropractic framework. This includes the assessment and treatment of musculoskeletal disorders, as well as related supportive care such as manual therapies and patient education on lifestyle modifications. Chiropractors are trained to provide non-invasive treatments and interventions designed to enhance the patient's overall health and well-being.

The other options, while varying in relevance, do not fall within the typical scope of practice for chiropractors in Massachusetts. Physical exams are indeed a part of what they do; however, the phrasing "only physical exams" suggests a limitation that does not accurately reflect the full range of services offered. Psychotherapy is outside the typical practice, as chiropractors are not trained or licensed to provide mental health therapy. Major surgical interventions, by their nature, require medical training beyond chiropractic education and are not a permissible function within chiropractic practice. Thus, normal chiropractic office procedures encapsulate the full range of services recognized under the chiropractic scope, making it the correct answer.
