Neuromusculoskeletal medicine (NMM), now more formally known as osteopathic neuromusculoskeletal medicine (ONMM), is a medical specialty of American osteopathic medicine. Physicians trained in the specialty focus on the clinical evaluation and management of disorders of the neuromusculoskeletal system and its related visceral and somatic structures. Both American DOs and MDs have the option to train and practice in any of the medical specialties and subspecialties. Neuromusculoskeletal medicine is a specialty which is dominated by DOs, but MDs may also become certified. ONMM physicians complete residency training that includes advanced training on the integration of osteopathic principles into inpatient and outpatient care. They have specialized expertise in the indications, risks, benefits, and application of osteopathic manipulative medicine (OMM) for treatment of patients with neuromusculoskeletal and visceral disorders.
