Overview
QuadStar II is a portable, digital NMES, IFC, and TENS device designed to stimulate sensory and motor nerves for disuse atrophy, muscle spasms, poor range of motion and the relief of chronic, arthritic and post-surgical pain.

Device features include: 9 preprogrammed fixed sequences which enable the user to program INF followed by NMES and ending with TENS therapy; plus a customizable program sequence and a Patient Compliance Meter.

The four-channel device incorporates touch proof design and a user friendly graphical interface.
