The Vibratron II provides a non-invasive means of measuring the sensitivity to vibration of a patient's hands and feet. Reliable quantitative measurements are achieved with a test that takes only minutes to administer. A two-alternative forced choice procedure is used to determine the degree of sensitivity.

LIGHTWEIGHT, STURDY EQUIPMENT
Vibratron II consists of a small controller and two separate vibrating rods. Vibration amplitude, which is continuously adjustable, is displayed on the front panel.

There are two ranges. For fine control, 0 - 6.5 vibration units corresponds to 0 - 20 microns. For low resolution, 6.5 - 19.9 vibration units corresponds to the 0 - 200 microns. A table and a formula are provided for conversion of

Possible environmental applications:

• Screening of multiple subjects for effects of exposure to neurotoxins - toxic dump sites, industrial accidents, solvents in chemical plants.
  
• Evaluating workers for job related cumulative trauma disorders such as carpal tunnel syndrome.

Clinically it is intended for use for:

• Early detection and monitoring of sensory loss resulting from diseases such as diabetes and alcoholism.
• Early detection of sensory loss resulting from drug therapy.
• Evaluation of nerve recovery after cessation of drug therapy or other treatment.
• Evaluation of nerve recovery after hand surgery.
