To the OP - I went into school wanting to do OP ortho/pain management type stuff because of my experience throughout undergrad. I work in a clinic that focuses on this stuff and really enjoy it. However, I'm still keeping my options open. Part of my clinical this summer will be with women's health, I'm also looking forward to my neuro affiliation. So, we'll see! But, I am still very much interested in ortho/pain management.
adh28 - My first clinical was with geriatrics. I honestly wasn't looking forward to it, but it definitely exceeded my expectations! In regards to finding your "niche" and getting special exposure, that's definitely an option at my program. Your full time internships have requirements (must fulfill one in ortho, acute, neuro, and geri), however if you want to explore more specialized areas (peds, women's health, vestibular, etc) you can do part time clinicals when you are in academic semesters. Or if you want to strengthen your area of interest, you can do all your part time clinicals in geri if you choose. This is just speaking for my program. I don't know if all give you the opportunity for part time clinicals throughout your curriculum. Hope that helped!
