Diagnostic tools for DPN

Diagnostic Tool

Outcome

Biothesiometer (Xilas VPTMeter)[1]

Identifies patients at high risk for foot problems by detecting degree of nerve damage; measures vibration perception threshold (VPT)

Neurometer[2]

Measures current perception threshold (CPT)

Computer-assisted sensory evaluation (CASE IV)[3]

Records both vibration and thermal measurements

Physitemp Vibratron II[4]

Measures sensitivity to vibration in hands and feet

Medoc TSA-II NeuroSensory Analyzer[5]

Assesses integrity of sensory nerve fibers by measuring vibratory or thermal stimuli (warmth, cold, and heat-or cold-induced pain)

Podotrack[6]

Identifies high-pressure areas

NC-stat nerve conduction system[7]

Measures nerve conduction of motor and sensory nerves

Electromyography (EMG)[8]

Nerve conduction studies and needle electromyography
