An apparatus and method are shown for simulating therapeutic manipulations with reduced risk of injury. The apparatus of the present invention includes a reciprocating body which fits into an axial bore of an elongate housing. A biasing member also fits within the axial bore and generates elastic resistance force in response when the reciprocating body and elongate housing are compressed together. A measuring device is included which measures the speed and amplitude of an impulse of the simulated manipulation and displays the results of the impulse on a display. The method of the present invention includes delivering an impulse of a therapeutic manipulation to the apparatus above rather than a training partner or an inanimate object, measuring the speed and amplitude of the impulse, and displaying the result of the measurement.

A manipulation device is programmable with different parameters associated with different manipulation exercises for different types of simulated patients. A measuring system determines the success or failure for any of the programmable manipulation exercises and tracks specific results that precisely track how close a student comes to specific target force values. This allows a student to more accurately track performance improvements and more effectively focus practice sessions on problem manipulation techniques. The measurement system not only measures the time and force values associated with the manipulation exercises but also measures angular displacement of the manipulation apparatus during the manipulation exercise. This allows the student to not only determine if a proper amount of force was applied during the manipulation exercise but also to determine if the force was maintained in the same direction and angle.
