An osteopathic doctor, known as a DO, is a fully licensed physician who can treat any medical condition an MD can. DOs practice across all medical specialties, from family medicine and pediatrics to cardiothoracic surgery and psychiatry. What sets them apart is additional training in the musculoskeletal system and a hands-on treatment method that gives them extra tools for certain conditions, particularly pain, mobility issues, and some systemic problems.
Full Medical Practice, Not Just Back Pain
There are more than 167,000 active DOs in the United States. About 55% work in primary care, but roughly 45% practice in non-primary-care specialties. The American Osteopathic Association certifies DOs in 24 primary specialties and 48 subspecialties, covering everything from dermatology and ophthalmology to neurological surgery, emergency medicine, and obstetrics. A DO can prescribe medications, order imaging, perform surgery, and manage complex chronic diseases. In terms of licensing, DOs complete four years of medical school followed by residency training, just like MDs.
The practical difference is that DO programs include additional coursework focused on the musculoskeletal system and a hands-on diagnostic and treatment method called osteopathic manipulative treatment, or OMT. This training shapes how many DOs approach patient care, even those who specialize in areas that have nothing to do with bones and muscles.
Conditions Treated With Hands-On Techniques
OMT is where osteopathic medicine most visibly differs from conventional practice. It involves moving muscles and joints using stretching, gentle pressure, and resistance. The most common reasons people receive OMT are lower back pain, neck pain, and migraines, but the applications go well beyond that.
For head and neck issues, a DO may apply gentle pressure to the head and spine to release tension. This approach is used for chronic headaches, neck stiffness, and temporomandibular joint (TMJ) disorders. Diaphragm techniques, which use soft pressure on the diaphragm to mobilize surrounding tissues, can improve breathing mechanics and ease certain types of back pain. A technique called lymphatic pump uses rhythmic, pulse-like pressure on the feet, chest, or abdomen to help clear congestion in the lymphatic system. This can reduce swelling and help relieve symptoms tied to respiratory infections and digestive issues.
OMT is also used during pregnancy to improve sleep quality and reduce musculoskeletal pain that comes with carrying extra weight in new places. For infants, some DOs use very gentle OMT techniques to address colic, breastfeeding difficulties, and recurrent ear infections.
Chronic Low Back Pain
Chronic lower back pain is one of the most studied areas in osteopathic treatment. A systematic review and meta-analysis published in Complementary Therapies in Medicine found that osteopathic interventions were significantly more effective than control treatments at reducing pain and improving functional status in people with chronic nonspecific low back pain. The effect sizes were meaningful: pain reduction showed a moderate effect, and improvements in daily function were statistically significant as well.
Within the different osteopathic techniques studied, myofascial release (a method focused on releasing tension in the connective tissue surrounding muscles) showed the strongest evidence for pain reduction, with benefits that persisted at follow-up assessments. For people managing ongoing back pain who want to reduce their reliance on medication, this is a practical option worth discussing with a provider.
The Osteopathic Approach to Diagnosis
Beyond OMT as a treatment, DOs are trained in a distinctive diagnostic method called the osteopathic structural examination. This is a systematic, hands-on assessment of the body that checks for areas of imbalance or restricted movement in the musculoskeletal system. The idea is that structural problems in one area, say a pelvis that’s slightly rotated, can contribute to symptoms somewhere else, like recurring headaches or digestive complaints.
During this exam, the DO evaluates specific anatomical landmarks from head to feet, both front and back, looking at alignment, tissue tension, and joint mobility. This information gets layered on top of the standard medical workup (lab tests, imaging, health history) to build a more complete picture. Not every DO performs structural exams regularly; it depends on their specialty and practice style. But the training influences how they think about the connection between physical structure and overall health.
Care for Older Adults
OMT has specific applications for elderly patients, particularly around balance, mobility, and fall prevention. Research published in the Journal of Osteopathic Medicine indicates that OMT can improve balance and mobility in older adults, both of which are critical factors in reducing fall risk. Treatment sessions in clinical studies typically lasted 20 to 45 minutes and were performed one to two times per week over several weeks. Some studies also found improvements in motor function, which matters for older adults managing conditions that affect movement and coordination.
For elderly patients dealing with joint stiffness, chronic pain, or reduced circulation, OMT offers a low-risk, non-pharmacological option. This is particularly valuable in a population that often takes multiple medications and benefits from treatments that don’t add to that burden.
The Philosophy Behind the Practice
Osteopathic medicine is built on four core principles that shape how DOs are trained to think about patient care. The first is that the body functions as a unit connecting body, mind, and spirit. The second is that the body has built-in mechanisms for self-healing and self-regulation. The third is that structure and function are deeply connected: how your body is built affects how it works, and vice versa. The fourth principle ties the others together: effective treatment should account for all of these relationships rather than focusing on a single symptom in isolation.
In practice, this means a DO treating someone for chronic migraines might also evaluate neck alignment, jaw tension, stress levels, and sleep patterns rather than jumping straight to medication. That doesn’t mean DOs avoid prescribing drugs or performing procedures. They use the full range of modern medicine. The philosophy simply adds a layer of thinking about how structural and lifestyle factors contribute to the problem, and whether addressing those factors could reduce the need for more invasive interventions.
