The CASE IV System is an automated device for characterizing peripheral sensory thresholds that have been altered by disease of sensory receptors, nerve fibers, central nervous system tracts, or cerebral association areas. Using a fully automated routine, the system administers noninvasive, precise, repeatable stimuli. It then records the patient’s responses and quantifies the patient’s sensory threshold using predetermined algorithms. The system is highly accurate, finely calibrated, and constructed so that test results generated by one system are comparable to all other units (all other testing factors being equal).
     A physician need not be present during the testing process, as long as a competent technician is present to prepare and instruct the patient and then monitor the course of the test. The system allows a patient to be tested over a period of time, following the course of sensory abnormality or improvement.
     Ultimately, inferences can be made about the course of a disease process or any effects of controlled clinical trials. Once a set of data has been collected, a database of normative values can be constructed, or the data can be compared with normative data already available, taking modality, site, age, and other variables into account. When patients are properly instructed and prepared for testing, the results of the sensory tests are highly sensitive, specific, repeatable, time-efficient, and quantified.

Two Modes of Testing:

The CASE IV System can determine three types of sensory thresholds using two modes, vibration and thermal:

• Vibratory Detection Threshold (VDT)
• Cooling Detection Threshold (CDT)
• Heat-Pain Detection Threshold (HPDT)
