If you’ve ever seen the letters “DO” after a physician’s name, you might have wondered what that means compared to the more familiar “MD.” Both are licensed physicians who attend medical school, complete residency training, and practice medicine across all specialties — but their educational philosophies have some meaningful differences worth understanding.
What Is Osteopathic Medicine?
Osteopathic medicine is a distinct branch of medicine founded in the late 19th century by Andrew Taylor Still, who believed that the body’s structure and function are deeply interconnected, and that the body has an inherent ability to heal itself when properly supported.
Today, osteopathic medicine is a fully accredited, evidence-based approach to medicine practiced by Doctors of Osteopathic Medicine (DOs). In the United States, DOs are licensed to practice the full scope of medicine and surgery, prescribe medications, and work in every specialty from surgery to psychiatry to emergency medicine.
DO vs. MD: What’s the Same, What’s Different?
The similarities are extensive. Both DOs and MDs attend four years of medical school. Both complete residency training after medical school. Both must pass licensing examinations (DOs take the COMLEX exam; MDs take the USMLE, though many DOs also take the USMLE). Both are licensed to prescribe medications and practice medicine in all 50 states.
The difference lies in the additional training DOs receive. Osteopathic medical schools include roughly 200 additional hours of training in Osteopathic Manipulative Medicine (OMM), which focuses on the relationship between the musculoskeletal system and overall health. This hands-on training teaches techniques to diagnose and treat health conditions through physical manipulation of the muscles, bones, and joints.
Osteopathic philosophy also emphasizes a whole-person approach to care — viewing the patient as a connected system rather than a collection of separate organs or symptoms. This often translates into longer consultations, more attention to lifestyle factors, and a focus on root cause rather than symptom management alone.
What Is Osteopathic Manipulative Treatment (OMT)?
OMT is the hands-on component unique to DO training. Techniques include soft tissue manipulation (similar to massage), joint mobilization, myofascial release, counterstrain, and high-velocity/low-amplitude thrusting techniques (similar to chiropractic manipulation).
OMT is used for conditions including lower back pain, neck pain, headaches, sports injuries, postural problems, and sometimes respiratory or gastrointestinal complaints. Research on OMT is mixed but generally supportive for musculoskeletal pain in particular.
It’s worth noting that not all DOs practice OMT regularly in clinical settings. Many specialize in areas where manual techniques are not a daily part of practice. However, the philosophical foundation of osteopathic training — whole-person care, emphasis on prevention, and appreciation of the body’s self-healing capacity — tends to influence a DO’s approach regardless of specialty.
Is Seeing a DO Different From Seeing an MD?
In most practical clinical settings, patients may not notice a significant difference in their day-to-day care between a DO and an MD. What you’re more likely to notice is the individual physician’s style, communication approach, and care philosophy — which vary widely among both DOs and MDs.
If you’re specifically interested in OMT as part of your care, look for a DO who actively practices it. Not all DOs offer OMT, particularly in specialty fields far removed from musculoskeletal medicine.
Both DOs and MDs can provide excellent, high-quality medical care. The best doctor is one who listens to you, respects your input, explains your options clearly, and partners with you in your healthcare.
