Indications for use: 2 channel JVA amplifier1. To record and display sounds/vibrations from the temporomandibular joints.2. To aid the clinician in their analysis of a joint sound/vibration by allowing them to see the waveform in various standard plots.3. To aid the clinician in comparing a patient's current stand plots to previous recordings before, during, and after treatment.4. To provide numerical values that can be used to quantify the physical characteristics of the sounds/vibrations, allowing intra-patient comparisons (only) by the clinician.

TMJ Vibration (Sound) Evaluation System. A lightweight headset holds highly sensitive vibration transducers over each TM joint, enabling simultaneous, bilateral capture of tissue vibrations emanating from joint sounds. Vibration (sound) data is correlated to vertical dimension of opening and closing, providing clinicians with valuable information to aid in assessing the status of articular disk and joint function.
