Although most cases of temporomandibular muscle and joint disorders (TMJD) are mild and self-limiting, about 10% of TMJD patients develop severe disorders associated with chronic pain and disability. It has been suggested that depression and catastrophizing contributes to TMJD chronicity. This article assesses the effects of catastrophizing and depression(More)
Electromyographic (EMG) recordings of the local twitch response in sixteen subjects with pain from active myofascial trigger points in the upper trapezius muscle were examined and compared with recordings from the contralateral normal muscle bands in the same individual. Needle electromyography and a specific reproducible snapping palpation technique were(More)
The Craniomandibular Index (CMI) was developed to provide a standardized measure of severity of problems in mandibular movement, TMJ noise, and muscle and joint tenderness for use in epidemiological and clinical outcome studies. The instrument was designed to have clearly defined objective criteria, simple clinical methods, and ease in scoring; it is(More)
Cold-freeze injury at -4 degrees C to the rat sciatic nerve produces mechanical allodynia and thermal hyperalgesia [M.A. Kleive, P.S. Jungbluth, J.A. Uhlenkamp, K.C. Kajander, Cold injury to rat sciatic nerve induces thermal hyperalgesia or analgesia, 8th World Congress on Pain, Vancouver, BC, Canada, August 1996 (Abstract).]. The NMDA receptor, an(More)
This study was conducted to investigate the range of mandibular movements in a normal population. Sixty-one male dental students were selected and a tracking device (Saphon Visi-Trainer [SVT] C-II) was used. The range of mandibular movements was measured in frontal, sagittal, and horizontal planes. Deviations of movements and angles between planes and path(More)
The personal health record (PHR) is proposed as an innovative solution to the problems of fragmented communication and lack of interoperability among diverse electronic medical record (EMR) systems. It provides a single source (the patient's PHR) for authentication and remote access of the health information data from all EMR systems. A voluntary survey was(More)
Temporomandibular joint internal derangement (TMJ ID) is the most common intra-articular TM disorder and can progress from TMJ ID with reduction to TMJ ID without reduction. It is not known whether this anatomical progression is associated with increasing levels of mandibular dysfunction. The objective of this study was to determine whether the level of(More)
Atypical facial pain is a persistent pain in the face or intraoral region that does not fit into the diagnostic criteria associated with specific orofacial pain disorders. This article presents the results of a study, which showed that in most cases of presumed atypical facial pain, there is a specific physical diagnosis or multiple diagnoses that causes(More)
The psychometric properties of the modified Symptom Severity Index were investigated to assess the relationships among dimensions of pain in temporomandibular disorders (TMD). The 15-item instrument is composed of ordinal scales assessing five pain dimensions (intensity, frequency, duration, unpleasantness and difficulty to endure) as experienced in three(More)
