I did with physical therapy. I did strengthening exercises so that keeping a straight back was much easier.

Hi

Also trying to tuck your tummy helps with posture.

Placing a stick on your back and arms helps greatly, although I dont recommend until you talk to therapist. But they did this to young people in school to teach posture.

Be well, Alma

me too! and now i can't sit up straight except for but a few minutes!

I do an exercise I got from my PT that helps posture. You can do it standing, sitting, driving, in the shower (at least I do): you squeeze together your shoulder blades, hold for count of 3, then repeat 10 times. Try to do it 3 times a day but like my PT says even once is better than none. It is easy to do and really helps your posture. There--you just saved a lot of money on a PT. Hope it helps you. I really do it when I drive and shower.

Another is tuck your chin all the way down and in, then use your neck muscle to raise your head. You shuld feel a nice pull.

The best methods ive found for dealing with poor posture are as follows

Foundation Training by Eric Goodman
Hanna Somatics by Thomas Hanna
Feldenkrais by Moshe Feldenkrais
Pilates by Joseph Pilates.

Im getting good results from Foundation Training at the moment.

my posture is terrible! Right now, I am on prednisone, which seems to help... so maybe it is partly related to MS? I have found that when I lift some arm weights, it seems to get better for awhile too. I'd like to be consistent in doing physio to see if that might work too. Let us know how it goes! Good luck!

The exersize Ezone mentioned did a world of good for me. I highly recomend it. I do it every time I go to the bathroom, as a reminder.
