Randomized Controlled Trial
Comparison of device-supported sensorimotor training and splint intervention for myofascial temporomandibular disorder pain patients.
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 3 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 was recorded under conditions of force-controlled submaximum and maximum biting in intercuspation. ⋯ Moreover, sensorimotor training was significantly (P < .05) less easy to use than the splint. The results of this study confirm the pain-reducing effect of sensorimotor training for patients with myofascial TMD pain (GCPS I and II). This innovative active treatment might be a promising option for TMD pain patients.

To investigate the effect of altering occlusal vertical dimension (OVD) in patients with severe attrition on corticomotor control of the masseter muscles as assessed by navigated transcranial magnetic stimulation (nTMS). ⋯ The results suggest that alteration of OVD in patients with severe attrition was associated with signs of neuroplastic changes in the corticomotor control of the masseter muscles. The results of the study may add to our understanding of the putative mechanisms related to cortical changes in response to OVD alterations.
