An 18 year old male suffered a facial injury during a basketball game. Shortly after the injury he could not open his left jaw joint and had pain on both sides of his jaw, pain in his ear, and headaches. He completed a TMJ Scale to screen for the presence of a TMJ disorder. This test detects and measures physical symptom severity including pain, palpation pain, perceived malocclusion, joint dysfunction and range of motion limitation. It also screens for elevated levels of emotional distress, stress, chronicity and the presence of non-TMJ disorders that can complicate diagnosis and treatment.
After five months the patient was asked to take another TMJ Scale by his dentist. The second report, according to the dentist, "displays the dramatic improvement reported by the patient." His percentile rank on the Global Scale, which measures the overall symptom intensity of a TMJ disorder, fell from 65% before treament to 8%, and all of the other scale scores were no longer elevated. The dentist also reported that the TMJ Scale demonstrated that treatment had been successful and "provided data to both the patient and insurers that Maximum Medical Improvement had been attained."
