20 patients with severe trismus resulting from either trauma or infection have been treated using the method of "continuous dynamic jaw extension". The clinical results and the electromyographic tests show that almost complete rehabilitation of mandibular movement is possible. The treatment is most effective during the healing phase of the abscess and as an early treatment for the traumatised patient. Extension exercises should not be undertaken during the exudative phase of abscess formation. The reaction ability of the masticatory musculature obtained from the electromyographic investigations is defined in the "reactive myotonus-index". Thus the jaw extension appliance used is helpful both in the diagnosis and treatment of severe trismus.
采用“持续动态下颌伸展”方法治疗了20例因创伤或感染导致严重牙关紧闭的患者。临床结果和肌电图测试表明，下颌运动几乎完全恢复是可能的。该治疗在脓肿愈合阶段最为有效，也是创伤患者的早期治疗方法。在脓肿形成的渗出期不应进行伸展运动。从肌电图检查中获得的咀嚼肌反应能力在“反应性肌强直指数”中定义。因此，所使用的下颌伸展矫治器在严重牙关紧闭的诊断和治疗中均有帮助。
