More and more studies are being done with today's improved technology to show which exercises help and how many to do. In fact, this is providing therapists with the information needed to actually prescribe exercises. One size doesn't fit all! And one exercise doesn't work for all.
Your physical therapist is the best one to re-examine you and revise your exercise program. The therapist will look at a variety of factors including your muscle strength, posture, goals, flexibility, and overall health. Based on these, a specific program will be designed for you.
