Patients with temporomandibular joint dysfunctional activity (TM dysfunction) present with a diverse spectrum of clinical signs and symptoms. The multifactorial aetiology of such disorders has been noted. Diagnostic and therapeutic problems arise due to the inadequacy of quantifying the dysfunction. TM dysfunction can affect the muscles of mastication which are responsible for mandibular movement. A pantographic reproducibility index (PRI) is available to quantitatively and qualitatively measure a subjects ability to reproduce mandibular border movements. Physical therapy modalities are used in the management of TM dysfunction. Electrogalvanic stimulation (EGS) is such an example. The effect of electrogalvanic stimulation on subjects with and without TM dysfunction was assessed by Pantronic PRI appraisal in 20 subjects. No statistically significant differences were noted. At the individual level, some changes were observed in susceptible subjects.
颞下颌关节功能紊乱活动（TM功能紊乱）患者表现出多种多样的临床体征和症状。此类疾病的病因是多因素的，这一点已得到公认。由于功能紊乱量化不足，导致了诊断和治疗方面的问题。TM功能紊乱会影响负责下颌运动的咀嚼肌。全景描记重现指数（PRI）可用于定量和定性地测量受试者重现下颌边缘运动的能力。物理治疗方法被用于TM功能紊乱的管理，电刺激（EGS）就是其中一个例子。通过对20名受试者进行Pantronic PRI评估，来评估电刺激对有和没有TM功能紊乱的受试者的影响。未发现统计学上的显著差异。在个体层面上，在易感受试者中观察到了一些变化。
