Neuropathy Analyser - Vibrotherm Dx For Quantitative Sensory Testing Measurement of Peripheral Sensory Thresholds: Vibration and Thermal (Cooling, Heat-Pain). In diabetes mellitus, polyneuropathy is an important complication and should be diagnosed as early as possible in order to prevent damage to the patient. Determination of warm, cold, and heat pain thresholds enables one to judge small nerve fibre sensitivity. Failure to perceive variances in temperature in the extremities is the most decisive early symptom of distal symmetric polyneuropathy, a typical ailment accompanying diabetes mellitus (Ziegler 1988). The VIBROTHERM Dx can determine Vibratory Threshold, Cold pain Threshold and Heat Pain Threshold. This model Vibotherm Dx is a combination of VIBROMETER and THERMOMETRY HCP. Supplied with computer connectivity and software for data storage and patient report generation.
