To whom it may concern  As an orthopedic surgeon, who treats acute and chronic patient suffering from lower back problems, I recommend, the movement called anterior and posterior pelvic tilt.  Over the last 6 months I have been using Backlife in my practice, and I can report significant alleviation of lower back pain.  The device replicates in a unique and precise way the movement and mobility created by the therapist (know as anterior- posterior pelvic tilt manipulation as stated above). Backlife is a CPM (continues passive movement) device, which emulates this movement.  Backlife is very user friendly, does not require professional supervision & can be used by the one who suffers from lower back pain.  Due to the accurate, special and effective movement that Backlife creates, it is suitable and helps acute and chronic patients as one.  Sincerely yours, Prof   Moshe Salai Head of Orthopedic Department Rabin Medical Center, Belinson Campus ISRAEL
