Splint therapy is a common method for treatment of CMD patients. However, the clinical assessment of the therapy was depended on the sensibility of the patient. The purpose of this study was to evaluate splint therapy for CMD patients using the pressure pain threshold (PPT).The PPT measuring system consisted of a grip switch and a push-pressure sensor. The sensor pressed on the skin overlying the muscle concerned. As soon as the pressure sensation became painful, the patient relayed a signal via a switch-off. The pressure was then immediately released. The largest PPT at the time of a switch-off signal was recorded and stored in a laptop computer.The daily change of PPT was observed in 10 normal subjects and four CMD patients with muscle palpation during splint therapy. Each PPT was measured at four sites of the masseter muscle and two sites of the temporal muscle on each side.No difference of PPT between the sides was observed in normal subjects. However, PPT of the painful side was significantly lower than that of the other side before the splint therapy. This difference decreased over the period of splint therapy.The measurement of pressure pain threshold could be an important tool for the judgement of the effect of splint therapy.
