Forty subjects (age range 22 to 55 yrs.) were assigned randomly into two equal groups: (1) Experimental group received PRFE using the Energex unit (Energex, Inc. Emerson, New Jersey) and (2) Control group received PRFE placebo treatment using a sham device. Both groups received six applications to the TMJ area over two weeks. Data were analyzed for the following times: baseline, first and second follow-up visits. Numerical RatingScale scores for TMJ pain showed a significant reduction over time for the experimental group (mean = 6.13 to 3.05, p<0.001). There was also a significant effect for the controls (mean = 5.35 to 4.20, p=0.01). The effect for experimental subjects was a mean reduction of 3.07 versus 1.15 for controls. The significant reduction in controls was attributed to the placebo effect. The experimental group showed a significant increase in mouth opening (mean = 34.95 to 41.70 mm, p=0.002), right lateral movement (mean = 7.85 to 10.80 mm, p=0.001) and left lateral movement (mean = 7.65 to 10.85 mm, p<0.0001). No significant (p>0.1) change in the control group occurred for mouth opening (mean = 38.50 to 39.65 mm), right lateral movement (mean = 8.60 to 8.75 mm) and left lateral movement (mean = 8.50 to 8.80 mm). No side effects were reported during the treatment and the two week follow-up. These results suggest strongly that PRFE is a safe and effective treatment for TMJ arthralgia as well as for increasing mandibular range of motion.  ISSN : 0  Journal Name : J Can Dent Assoc.  Volume : 22  Issue Number : 1  Publishing Year : 2004 AH 2004 AD  Article Type : Article  Added Date : Thursday, December 6, 2007  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email خالد زواوي zwawi, khalid Investigator Doctorate kzawawi@kau.edu.sa Files File Name Type Description  Efficacy of Pulsed Radio Frequency Energy Therapy in.pdf pdf   Back To Researches Page
