Joint Vibration Analysis

Temporomandibular Joint Vibration Analysis (JVA) is the electronic recording of TMJ sounds, or more accurately, vibrations occurring in the joint.  Utilizing vibration transducers called accelerometers, a characteristic wave pattern is created for the various types of internal joint vibrations (conditions).

A very simple principle: Bio-JVA is based on simple principles of motion and friction:  When smooth surfaces rub together, little friction is created…and little vibration.  If these surfaces become rough, then friction and vibration are created when these surfaces articulate.

Fast and accurate: JVA provides a fast, non-invasive, and repeatable measurement of TMJ function to aid in the diagnosis of TMJ function.

How it works:  Human joints have surfaces which rub together in function.  smooth, well lubricated surfaces in a proper biomechanical relationship produce little friction and little vibration.  But surface changes, such as those caused by degeneration, tears, or displacements of the disk, generally produce friction and vibration.  Different disorders can produce different vibration patterns or “signatures”. PC-assisted vibration analysis helps identify these patterns and helps your doctor distinguish among various TM disorders.

Recorded by staff, read by the Doctor:  A JVA recording only takes 10 seconds and taken by the staff.  Interpretation is done by Dr. Wiesse and takes only a few minutes.
