Wave Forms
The waveform that is produced when this technology is employed is similiar to a fingerprint of the material being tested.
Are frequency and waveforms important?
The waveform produced by the complex interaction between the patient, induced force and the piezoelectric sensor is the output used by the ProAdjuster to access joint compliance. By having this waveform, we have the ability to determine the natural frequency of the joint complex. The waveform is the basic output used by ProAdjuster and other testing systems used in the published research.
A single component of the waveform is the amplitude or height of the waveform. This is only a measure of stiffness and contains no other information about the joint. While this measure is important it does not take into consideration or use all of the information that is available from the waveform. From the waveform frequency can be derived and well as the hysterisis (Mechanical property of a visoelastic system to deform and then come back to its original shape). By using all the information available, the ProAdjuster system, under protection of a patent, uses all the information to produce a more complete view of the patients condition.
The ProAdjuster is in a unique position that all the waveform information is available to the doctor. Below is the supporting research that explains the critical nature of waveforms and frequency.
