The device must have randomized testing in order to prevent predictability. The time between each force application, the force levels, and the testing sites will be randomized.

DESIGN SOLUTION
A microprocessor will be coded to create randomized time intervals, force levels, and testing sites. Two applications and a ‘sham’ application will be applied per force at each testing site. The microprocessor will be wired to motor drivers in order to control the stepper motors.
