It’s me again, commenting now on PT’s, as an OT who has worked with, and has been worked on by PT’s for a variety of issues over my life. I have come to understand first hand as you have, that probably most PT’s do not know the in’s and out’s of REALLY GOOD, SAFE, EFFECTIVE exercise s for osteopenia/osteoporosis.
Unless they have really taken an interest and dug deeper into the specifics or done extra teaching /training at conferences , they will probably be providing you with general weight bearing exercises, using weights on your hands , having you do machines in their office/gym. That is not good enough and as you’ve realized can sometimes be unsafe or detrimental.
