With the lower spine under EED (Expanding Ellipsoidal Decompression), the lumbosacral region is gently though powerfully translated along the Y-axis and simultaneously rotated and unwound on the X-axis. This unique blend of five simultaneous force vectors cannotbe manually duplicated. Simply stated, the Penta Vec 2500, lifts and expands the lumbar spine while the sacrum and pelvis are rotated up and translated away. The feeling is one of lightness and freedom from the monotonous compressive coiling in the lower discs and joints.
