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.
