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.
An assembly of mains electricity (AC-powered) devices designed to record parameters for mandibular and muscles of mastication function, primarily to aid in the diagnosis and treatment of temperomandibular joint (TMJ) and myofascial pain dysfunction (MPD) disorders, and for orthodontic, denture, and reconstruction patient evaluation. It typically uses surface electromyography to evaluate muscle groups at rest or in function; sonography to detect sounds/vibrations from the TMJ joint and/or other computer-based system to non-invasively track the mandible in function or identify its position in space relative to the skull.
