Vibration sensation threshold (VPT) is an important method for quantitative sensory measurement (QST). It provides a quick, economical and accurate early screening method for diabetes peripheral neuropathy (DPN), and can find high-risk people with serious complications such as diabetes foot as soon as possible.

VPTClinical application:

· Diabetes peripheral neuropathy examination.
· Male sexual function sensitivity nerve examination.
· Neurological and surgical sensory dysfunction assessment.
· Postoperative sensory nerve rehabilitation function assessment.
· Identification of neurological function in occupational diseases.
· Evaluate acute and chronic poisoning events.
· Used for pharmacology and drug research projects.

Why do we need a quantitative sensory examination?

· Sensomotor and peripheral sympathetic neuropathy are the main risk factors for foot ulcer in diabetes.
· Neuropathy cannot be diagnosed solely based on medical history, and a careful examination of the feet is necessary.
· More than 50% of diabetes patients have obvious neuropathy and "high-risk foot".
· Some prospective studies have confirmed that sensory loss is the main "alarm symptom" of foot ulcer. Therefore, it is necessary to conduct regular foot nervous system examination for all patients with diabetes.
