saxonmacleod,
Like Steve, I too am a MS-II at KCOM. I don't know that I have a diagnostic kit in my hands, but, I think they are certainly part of my diagnostic kit. That is to say, that in my limited experience, I wouldn't want to not have my hands. I need the stethoscope, opthalmoscope, etc. and I need my hands. The one thing that you will learn above all else at a D.O. school is to be comfortable touching another person. This is a skill that has to be worked upon, especially in our society, where touching has so many negative or sexual conotations and it is often unsettling to touch another person with whom your are not familiar. OTM, by its very nature, is very tactile, and in learning OTM you become very comfortable in touching people.
In addition to learning to be comfortable in touching another person, and more to your question, OTM does force you to be aware of what the musculature and skeleton are doing. Am I more advanced or a better in palpation than a traditional allopathic student...I don't know, however, I am sure that I have felt more backs, necks, legs, arms, etc. than most other 2nd year medical students, and as such I have more experience to tell me when something "ain't right." And if I can feel something that isn't right perhaps it will give me a clue to look for something else that might be wrong with the patient, or, help to narrow my search when diagnosing a problem.
I realize the above ramblings aren't real specific, however, as a 2nd year student, I don't have a lot of clinical experience. Perhaps a 3rd or 4th year student with more experience, or a practicing physician could answer your question more completely and with better examples.
Sincerely
Sweaty Paul 🙂
