Product model: VPT-Ⅰ
1 Overview:
Vibration sensory threshold tester (VPT-Ⅰ) is a simple, non-invasive neurological function test instrument. Used to provide vibration locally, detect
The patient's sensory threshold for vibration can assist in diagnosing whether the patient has neurosensory system diseases. Tests that can be used to detect the human peripheral nervous system
Research progresses such as testing, screening of diabetic foot disease, deep sensory disturbances produced by the sensory center of the brain, deep sensory nerve fiber lesions, and nerve regeneration.
Perform non-invasive assessments and measurements. It can provide the basis for clinical diagnosis and scientific research for detection items related to vibration perception threshold.
