    Ultium EMG System. The benefit provided by use of the device is the provision of objective measures to assess the severity of pathological human movement conditions and gauge any subsequent improvement offered by therapy, training or design changes.

  • Page 6: Introduction

    2.3 Intended Use Noraxon’s Ultium EMG sensor is intended to measure and quantify muscle biopotential signals separately or in combination with other kinematic or kinetic signals. These inter-related measurements can provide data to assist in understanding movement abnormalities. The system is designed as a diagnostic tool for clinical, investigational and research applications.
