TI  - Short-term effects of dry needling of active myofascial trigger points in the 
      masseter muscle in patients with temporomandibular disorders.
PG  - 106-12
AB  - AIMS: To investigate the effects of dry needling over active trigger points 
      (TrPs) in the masseter muscle in patients with temporomandibular disorders (TMD). 
      METHODS: Twelve females, aged 20 to 41 years old (mean = 25, standard deviation 
      +/- 6 years) diagnosed with myofascial TMD were recruited. Each patient attended 
      two treatment sessions on two separate days and received one intervention 
      assigned in a random fashion, at each visit: deep dry needling (experimental) or 
      sham dry needling (placebo) at the most painful point on the masseter muscle TrP. 
      Pressure pain threshold (PPT) over the masseter muscle TrP and the mandibular 
      condyle and pain-free active jaw opening were assessed pre- and 5 minutes 
      postintervention by an examiner blinded to the treatment allocation of the 
      subject. A two-way repeated-measures analysis of variance (ANOVA) with 
      intervention as the between-subjects variable and time as the within-subjects 
      variable was used to examine the effects of the intervention. RESULTS: The ANOVA 
      detected a significant interaction between intervention and time for PPT levels 
      in the masseter muscle (F = 62.5; P < .001) and condyle (F = 50.4; P < .001), and 
      pain-free active mouth opening (F = 34.9; P < .001). Subjects showed greater 
      improvements in all the outcomes when receiving the deep dry needling compared to 
      the sham dry needling (P < .001). CONCLUSION: The application of dry needling 
      into active TrPs in the masseter muscle induced significant increases in PPT 
      levels and maximal jaw opening when compared to the sham dry needling in patients 
      with myofascial TMD.
