Abstract
The aim of the present study was to evaluate the efficacy of low-level laser therapy (LLLT) and the microelectric neurostimulation (MENS) in the treatment of patients with temporomandibular disorders (TMD). A sample of 19 individuals presenting with signs and symptoms of myogenic TMD was randomly divided into two groups (I - LLLT and II - MENS). Therapy was done in 10 sessions, three times a week, for one month. Patients were evaluated by the Visual Analogue Scale (VAS), measurement of active range of motion (AROM) and muscle palpation, performed immediately before and 5 minutes after each therapeutic session by a blinded TMD specialist. The ANOVA for repeated measurements and Mann-Whitney tests were used for the statistical analysis. The results showed an increase in maximum mouth opening and a decrease in tenderness to palpation for both groups. The VAS reduced for both groups, although more evident for the laser group (p<0.05). Authors concluded that both therapies were effective as part of the TMD treatment, and the cumulative effect may have been responsible for this fact. However, caution is recommended when judging the results due to the self-limiting aspect of musculoskeletal conditions such as TMD.

Combined therapies have been proposed in the management of symptoms of temporomandibular disorders (TMD)
Combined therapies have been proposed in the management of symptoms of TMD
According to Ogus and Tooller[26] (1986) and Guralnick[16] (1984), TMD management is more effective when patient is treated according to a logical sequence of importance, i.e.: treatment of the symptoms, of the underlying cause, of the predisposing factors, and eventually treatment of the pathological effects
Summary
Combined therapies have been proposed in the management of symptoms of TMD. This interdisciplinary approach is necessary because of the multifactorial aspect of these problems. Different forms of treatments other than the historical occlusal are part of the global management and are known as supportive therapy[27]. According to Ogus and Tooller[26] (1986) and Guralnick[16] (1984), TMD management is more effective when patient is treated according to a logical sequence of importance, i.e.: treatment of the symptoms, of the underlying cause, of the predisposing factors, and eventually treatment of the pathological effects. To increase patient’s awareness of the cause of symptoms, to achieve muscle relaxation, to reduce muscle hyperactivity, reestablishing joint movement, to relieve pain, and to allow a normal function are common physical therapy goals and objectives. Microcurrent therapy (MENS) and soft laser are some of these modalities
