Efficacy of an early intervention for patients with acute temporomandibular disorder-related pain: a one-year outcome study.
BACKGROUND The authors conducted a r and omized clinical trial to evaluate the efficacy of a biopsychosocial intervention for patients who were at high risk ( HR ) of progressing from acute to chronic temporom and ibular disorder (TMD)-related pain . METHODS The authors classified subjects ' risk using a predictive algorithm and r and omized them into an early-intervention ( EI ) or a nonintervention ( NI ) group . The EI included cognitive behavioral skills training and biofeedback . The authors assessed pain and psychosocial measures at intake and at a one-year follow-up . Subjects '  self-reported pain levels were measured on an analog scale and as a response to palpation . RESULTS At one year , EI-group subjects had significantly lower levels of self-reported pain and depression . At one year , more NI-group subjects than EI-group subjects had utilized health care for jaw-related pain . NI-group subjects were 12.5 times as likely to have a somatoform disorder , more than seven times as likely to have an anxiety disorder , and 2.7 times more likely to have an affective disorder at one year , compared with EI-group subjects . CONCLUSIONS EI-group subjects had reduced pain levels , improved coping abilities and reduced emotional distress at one year . CLINICAL IMPLICATION S The TMD-related pain experience is complex and requires early identification with a biopsychosocial EI to achieve maximal , sustainable results
