Vibration II Vibrations Sensitivity Tester from Physitemp

Physitemp’s Vibratron II Vibration Sensitivity Tester provides a non-invasive way to measure the vibration sensitivity of a patient’s hands and feet. This test takes only minutes to achieve reliable quantitative measurements. A two-alternative forced choice procedure is used to measure the degree of sensitivity.

Lightweight, Sturdy Equipment

The vibration sensitivity tester contains two separate vibrating rods and a small controller. Vibration amplitude is displayed on the digital front panel and it can be continuously adjusted using output control.

Vibratron II is available in two ranges:

  • For low resolution, 6.5 - 19.9 vibration units correspond to the 0 - 200 µm
  • For fine control, 0 - 6.5 vibration units correspond to 0 - 20 µm

A table and a formula are given for conversion of

Possible environmental applications:

  • Evaluating workers for job-related cumulative trauma disorders like carpal tunnel syndrome
  • Screening various subjects to identify effects of exposure to neurotoxins - industrial accidents, toxic dump sites, and solvents in chemical plants

Clinically it is intended for use for:

  • Early detection of sensory loss caused by drug therapy
  • Early detection and monitoring of sensory loss caused by diseases like diabetes and alcoholism.
  • Evaluation of nerve recovery following hand surgery
  • Evaluation of nerve recovery following cessation of drug therapy or other treatment


The key features of the Vibratron II Vibration Sensitivity Tester are as follows:

  • Assess peripheral nerve function
  • Monitor peripheral neuropathy
  • Field studies or clinical testing
