This last article in the three-part series on devices for the diagnosis and treatment of temporomandibular disorders (TMD) compared the claimed diagnostic usefulness of thermography with the present scientific evidence. In a similar manner, the therapeutic efficacy of ultrasound, electrical stimulation, and electromyographic biofeedback was also reviewed. This evaluation concluded that the application of thermography to the diagnosis of TMD is limited by variations within and among subjects and by intrinsic problems with controls of the test environment. It also concluded that evidence that therapeutic ultrasound alone is useful for the treatment of TMD is lacking, that positive clinical results of electrical stimulation may not be due to specific therapeutic effects, and that it is doubtful that the use of electrical stimulation devices can produce a position of the mandible that has any diagnostic or therapeutic significance. There is evidence, however, that relaxation training, assisted by EMG biofeedback, can reduce daytime muscle activity.
