Chiropractic: Musculoskeletal Pain Affects School Teachers.
An assessment of 486 self-evaluation surveys from female school teachers in Saudi Arabia reveals that musculoskeletal pain is surprisingly prevalent in the profession. Their most common complaint was low back pain, followed by knee pain, heel pain, shoulder pain, upper back pain, hip joint pain, ankle pain, and neck pain. Furthermore, nearly half (46.1%) of the teachers surveyed claimed that their pain affected their teaching performance. Pakistan Journal of Medical Sciences, November 2014

Any stats on U.S. teachers?

I remember reading about a similar study involving self-assessed pain disability scores and US teachers but I can’t remember where…. I’ll see if I can seek it out and provide a link to the abstract. In my experience, these kinds of numbers likely translate to most developed nations in a general sense.
