About QST Products

The QST technique offers an alternative method and a complement to the standard nerve conduction and evoked potential testing for assessment of sensory function.

Somedic products include a number of tools designed to determine functions in the peripheral and/or central nervous system by applying physiologically relevant stimuli with known mechanisms of action to the skin. Each type of stimuli is designed specifically for different neuroanatomic pathways and discrete fibre populations.

Somedic products are dedicated, non-invasive instruments that are easy to learn and use in a large field of applications, such as diagnosing diabetes, whiplash injuries, occupational diseases and pain analysis. Further they may be used to evaluate effects from transplant surgery, oral surgery, orthopaedic surgery as well as neurological examinations and applications.

Somedic products and their individual componets are
• CE-marked and comply with the MDD93/42/EEC directive
• Currently not approved for sale in the US (for research use only).

What is QST?
• Stands for Quantitative Sensory Testing
• The general idea is to assign a subjective value of sensation to a known (objective) sensory stimuli

Why use QST instruments?
• To screen for peripheral nerve fibre dysfunction
• To determine the distribution and severity of neurological damages and disturbances
• To measure the outcome of (medical) treatment
• To monitor work related neurological damages on the work force
• To monitor and warn about neurological side-effects in drugs with potential neuropatic risks
• Evaluation of pharmacological and other treatments
• Early detection of toxic effects from the environment
