The Model BEP IX is a system designed to objectively measure tactile sensitivity. A complete BEP IX system consists of: 1) HPM's proprietary "BEP for Windows" software that runs on a user-supplied "host computer" and allows the user to focus on the test subject, not the ancillary tasks of measurement; 2) a microprocessor-based interface and control unit (BEP IX ICU, sold separately $1495) that interfaces to the host computer through a simple serial port connection; 3) individual, separately purchased (inquire regarding availability) ergonomically designed and tested stimulation subunits (BEP IXa - vibration, BEP IXb - thermal sense, BEP IXc - touch/pressure, BEP IXd - two-point discrimination, and BEP IXe - electrical current perception); 4) a compact power supply; and 5) a step by step manual for easy set-up and with detailed instructions for each test procedure. Most sensory tests use a modified von Bekesy protocol (similiar to that used in hearing screenings) that allows rapid and accurate estimation of sensory thresholds. The testing process is completely automated (e.g., computer control of stimulus amplitude and application window durations, etc.), virtually eliminating the involvement of the examiner and thereby improving consistency of results. Stimulus generators use the latest technology and incorporate innovative features that result in compact packages. Standard test sites are identified for the hand and foot. For researchers, special configurations can be supplied for stimulating other body sites.
