Title Grindcare Units Reduce Electromyographic Activity In Muscles Of TMD Patients During Sleep
Clinical Question With a patient who has chronic temporomandibular disorder (TMD) pain, would providing the patient with a GrindCare unit used at night be more effective than providing the patient with no treatment, in reducing the patient's TMD symptoms?
Clinical Bottom Line The use of a Grindcare unit can reduce the number of EMG episodes in temporomandibular joint muscles per hour of sleep; however, it neither reduces patients’ pain nor increases patients’ hours of sleep as compared to no treatment.

(level of evidence)
#1) 23148551Jadidi / 2012Eleven subjects with myofascial temporomandibular disorders with a clinical diagnosis of bruxism Randomized Controlled Trial
Key resultsThe number of EMG episodes per hour of sleep was significantly reduced in patients using the Grindcare system compared to baseline (at p = 0.021). However, there were no significant differences in the number of painful muscles, maximum pain-free jaw opening, pain intensity, depression scores (at p > 0.513) or muscle tension scores (at p = 0.646) between groups that did and did not use the Grindcare system. Additionally, there was no significant difference in the average duration of sleep of patients with or without the Grindcare system (at p= 0.646).

Comments on
The Evidence
This study was a double-blind randomized controlled trial. The groups were similar at start, and each subject completed the study. The groups were treated the same, except that one group received active Grindcare treatment while the other did not. There was adequate follow-up of the subjects’ responses and adequate compliance by the subjects. The author of the study is the inventor of Grindcare.
Applicability These subjects are representative of many patients with temporomandibular disorder pain. The treatment is feasible in most settings; however, the cost of purchasing a Grindcare unit as well as patient comfort during sleep may be limiting factors to its widespread use.
