LiftTrainer

The LiftTrainer is a behaviorally oriented approach to improving lifting techniques. By using a combination of biofeedback, biomechanical analysis tools, and one on one coaching, the LiftTrainer protocol guide individuals towards lifting behaviors that lower the forward bending, lateral bending, and twisting moments ("stresses") acting on the spine while maintaining desired productively levels.

The subject is first instrumented with sensors at key anatomical landmarks. These sensors allow a magnetic motion monitoring system to create a computer model of the subject, which in turn allows measurement of lateral bending, twisting, and forward bending moments. Graphs of these peak values are shown to the subject after (s)he performs 4-6 approximately normal lifts. Additionally, the subject hears a sound feedback which corresponds to the current sum of the three moment values in real-time. The coach attempts to help the subject reduce the peak moments by asking the subject to modify their lifting techniques over the course of 5-10 training sets of 4-6 lifts each & monitoring the moment values for signs of improvement.
