The CASE System is an automated device for measuring sensory

thresholds. A series of safe, precise, repeatable, stimuli are administered

to the subject and are recorded and quantified using proven algorithms

and a validated testing protocol. Stimuli include heat-as-pain, cooling

and vibration. Test results are compared to widely-recognized

normative data (provided courtesy of Peter Dyck, M.D. Rochester MN)

and are expressed as percentiles and normal deviates.

Highly accurate and precisely calibrated, the CASE has a robust

construction that makes it ideal for controlled, standardized and rapid

testing, assuring clear and accurate data from patient to patient and for

serial testing of individuals. A broad range of stimulus intensities can be

delivered, and is able to test the most sensitive and insensitive patients.

The CASE QST System is used to recognize hyposensitivity,

hypersensitivity and hyperalgesia. It is useful in demonstrating

abnormalities in small fiber neuropathies and dysfunction of Αδ fibers

(cooling detection testing), large diameter sensory fibers mediated by

Ααβ, and abnormality of unmylenated dorsal root C (drC) fibers.
