The purpose of this study was to clarify the electromyographic property of chewing movement before and after treatment in patients with non-reducing disc displacement of the temporomandibular joint (TMJ). Twenty patients who were diagnosed with unilateral non-reducing disc displacement of the TMJ were treated by pumping and injection of sodium hyaluronate into the joint. Chewing movement in these patients was evaluated by electromyography (EMG) at the initial visit and at mean 19-month follow-up and the results were compared. Chewing movement in 23 normal controls were also examined. Duration of contraction, cycle time and integrated value at the initial visit which were different from those in the controls without TMJ dysfunction tended to be at the control level mean 19 months after treatment of pumping and injection of sodium hyaluronate into the joint in patients with non-reducing disc displacement of the TMJ. Electromyography appeared to be a method of documenting the chewing movement which was impaired at initial visit improved after treatment in patients with non-reducing disc displacement of the TMJ.
