The Model BEP II is a multi-function system designed to acquire a standardized set of performance measures, nearly all of which are directly or indirectly associated with lower extremity motor control functions.

The BEP II system consists of:

• 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;
• a rugged lower extremity unit (the BEP II module) that interfaces to the host computer through a simple serial port connection and provides visual stimuli and senses test subject responses made with the lower extremities during one of the multiple standard test protocols;
• a compact power supply; and
• a step-by-step manual for easy set-up and use.

The BEP II module is positioned on the floor in front of a seated subject (or under the leg of a standing subject for some protocols) who uses it to execute lower extremity tasks designed to stress specific performance resources. It has six high speed touch sensors (two groups of three) and two high intensity/high speed semiconductor lights (one per group of sensors). Tests consist of short, well-defined tasks (10-30 sec) that permit rapid documentation of performance capacities that have been established as important characteristics of the involved subsystems and are important to the execution of higher level tasks such as gait.
