At the same time, recent studies show an increasingly positive attitude of patients and physicians (MD and DO) towards the use of manual therapy as a valid, safe and effective treatment modality. One survey, published in the "Journal of Continuing Medical Education", found that a majority of physicians (81%) and patients (76%) felt that manual manipulation (MM) was safe, and over half (56% of physicians and 59% of patients) felt that manipulation should be available in the primary care setting. Although less than half (40%) of the physicians reported any educational exposure to MM and less than one-quarter (20%) have administered MM in their practice, most (71%) respondents endorsed desiring more instruction in MM. Another small study examined the interest and ability of MD residents in learning osteopathic principles and skills, including OMT. It showed that after a 1-month elective rotation, the MD residents responded favorably to the experience.
