To put my personal biases on the table:

1) My younger son is currently studying for a DPT degree. Knowing how rigorous his training is gives me a positive view toward physical therapy.

2) I like my medicine conservative, with things like surgery as a last resort.

3) For orthopedic or other medical problems which could affect my physical activity (cycling, walking, some jogging, enough weight lifting to maintain my upper body strength), I want to see a medical professional who actively participates in at least some of the same activities. We have a couple of well-regarded local holistic sports medicine offices in which physical therapists, chiropractors, radiologists, and orthopedic surgeons practice collaboratively.

4) I am extremely cautious when it comes to chiropractors, acupuncturists, etc. There are many very good and effective ones -- some of whom are personal friends -- who freely acknowledge their limitations and know what they are doing, but these professions need to clear out their bad apples.

5) I have felt the impacts of improper fit on a bicycle, and I fortunately resolved this before doing permanent spinal or nerve damage. For me, the worst thing was an excessively long forward reach to the bars, which is why I care more about a frame's top tube length than its seat tube length. I have also swallowed my pride and raised my handlebar stem a bit, which also helps.
