Backlife uses CPM (continuous passive movement ) to treat pain 
in the lower back.
CPM gently contracts and extends the spine 
which helps to relieve pressure on the 
vertebrae and discs, relaxing the
muscles that attach to your spine.
CPM is used by many back pain 
therapists.

If you can have physiotherapy then you
can use back life. If in doubt consult your
doctor before use.
