What are the therapeutic uses of yoga?

relaxation

Yoga has a number of benefits including relaxations, stress release, improved sleeping patterns, excercise, physical therapy and more.

I use yoga to maintain flexibility and strength in my core. A number of years ago I slipped a disc in my lower back and it took 12 months to recover.
I have to do yoga and pilates regularly to keep the muscle groups in the lower back strong and flexible to help prevent it slipping again.

I guess yoga has a lot of applications.
