Somedic MSA Thermal Stimulator NG

The Modular Sensory Analyzer for thermal testing
The Somedic MSA NG is an advanced diagnostic system which has evolved from Somedic SenseLabīs extensive experience in developing and manufacturing sensory equipment. Somedic MSA NG sets a new standard in function, performance and safety, meeting the requirements of the most demanding user.

The Somedic MSA NG is a modular system, giving users the option to upgrade and/or add new functions. Also our modular components facilitate service and maintenance. All communication with the Somedic MSA NG goes by the standard serial port. A (lap top) computer is sufficient for efficient work.

The Thermal Stimulator features an innovative new design in thermodes. The new thermodes offer high thermal capacity and exceptionally even temperature distribution across the thermode surface. The thermodes include dual temperature sensors on the thermode surface and a third on the thermode heat exchanger.

Key application
• Quantification of small fibre function
Key features
• Thermal stimuli with high accuracy and repeatability
• Thermodes of different sizes, that easily can be exchanged, adapting the Somedic MSA NG to tests at different anatomical locations
• A dedicated Windows program that handles all set-ups and running of the Somedic MSA NG, as well as storage of the results in a standard Access databases, that facilitates the generation of various types of reports

Technical Specification - Somedic MSA NG (Next Generation)

Intended use
Somedic MSA NG is intended for the study, in medical practice and research, of the relationship between the intensity of controlled thermal stimuli and the associated percept(s). Determination of perception and/or pain thresholds are performed by using a hand-held transducer to apply on intact skin stimuli of accurately controlled temperatures.
