The CASE IV QST lab focuses on the testing of sensory abnormalities in the areas of temperature change sensation, vibration, and pain threshold testing. 

Safe and proven testing patterns developed at the Mayo Clinic® assist in the assessment of sensory abnormalities due to neurologic disease, help in the determination of type of dysfunctional fibers, and quantitatively verify the effectiveness of small and large unmyelinated nerve fibers.

The CASE IV QST lab utilizes two stimulators to determine sensory threshold. Patient responses to safe, effective stimuli are used to generate a sensory threshold level which are then compared to reference data available with the WR TestWorks software.

The CASE IV QST lab includes stimulators, patient instruction cards for clear, concise, and standardized instruction, a patient supply kit, an equipment cart, and a computer running the WR TestWorks software with printer. Get more functionality from your lab by adding a Q-Sweat or Cardiac system. On-site installation and training is included for all labs in the United States and Canada.
