Amplitude and frequency spectrum of temporomandibular joint sounds from subjects with and without other signs/symptoms of temporomandibular disorders.
Temporomandibular joint (TMJ) sound is one of the most commonly recognized signs in patients with temporomandibular disorders (TMD) but is also frequently seen in asymptomatic individuals. Sound recording is therefore only meaningful if the sounds from a normal healthy joint can be differentiated from those in patients. In this study, the amplitude and power spectrum of the TMJ sounds from symp...
متن کاملA new method for acquisition and analysis of single unit recording data
Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...
متن کاملVibration Arthrography as a Diagnostic Method for Osteoarthritis of the Knee joint
The technique of vibration arthrography (VAG) permits the non-invasive evaluation of internal derangements of the knee. In this method, the delicate sounds emitted from a joint are recorded by a sensitive detector which is placed on a joint, and the resultant signals are depicted by an oscilloscope. The primary objective in this study was to examine the vibration signal patterns associated with...

متن کاملModified stethoscope for auscultation of temporomandibular joint sounds.
BACKGROUND Purpose of this study was to modify the stethoscope which can auscultate the temporomandibular joint (TMJ) sounds more precisely than conventional stethoscope, and fabrication of stethoscope compatible software which analyses the auscultated sound and gives documentary evidence of that analysis in the form of graph. MATERIALS & METHODS The conventional stethoscope was modified by a...
