Objectives: Purpose of this study was to compare the short-term therapeutic efficacy of device-supported sensorimotor training with that of standard splint therapy for patients with myofascial temporomandibular disorder (TMD) pain over a treatment period of three months. We tested the hypothesis that both types of intervention are equally effective for pain reduction. In addition, the electromyographic (EMG) activity of the temporal and masseter muscles were recorded under conditions of force-controlled sub-maximum and maximum biting in intercuspation.

Methods: Of consecutive patients seeking treatment for non-odontogenic orofacial pain, 45 patients with functional myofascial TMD pain (graded chronic pain status, GCPS, I and II) were randomly assigned to two treatment groups (sensorimotor training and conventional splint treatment). Patients were evaluated four times (initial examination, 2, 6, and 12 weeks later) by use of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). EMG activity was recorded at the initial session and after three months. Ease-of-use of the treatment options was also evaluated.

Results: Significant (p<0.001) pain reduction (sensorimotor training 53%, splint therapy 40%) was achieved for both groups, with no significant differences (p > 0.05) between the groups. EMG activity under sub-maximum bite force during the first and last sessions was not significantly different (p>0.05). During maximum biting, however, EMG activity was approximately 20% greater (p<0.01) for the masseter muscle in both groups after the treatment period. In contrast, a significant increase (p<0.01) for the temporal muscle was only observed in the sensorimotor training group. Moreover, sensorimotor training was significantly (p<0.05) less easy to use than the splint.

Conclusions: The results of this study confirm the pain-reducing effect of sensorimotor training for patients with functional myofascial TMD pain. This innovative active treatment might be a promising option for TMD pain patients.
