Abstract
Objective: To compare between the effects of global postural exercise program against muscle energy technique on maximum pressure pain threshold, maximal mouth opening range of motion as well as quality of life on patients with temporomandibular joint disorders. Methods: 63 patients having temporomandibular disorders were randomized into three groups; Group (A) were given global postural exercise program in addition to conventional therapy (in the form of LASER and hot packs), Group (B) were given muscle energy technique as well as traditional therapy and the Group (C) control were given traditional therapy only. All patients were examined by the pressure algometer, paquimeter and Arabic version of Oral health impact profile 14 questionnaire as well as the duration of treatment were 6 weeks. Results: there were no significant statistical differences revealed pretreatment for all variables, Mmaximal mouth opening range of motion, quality of life scale, as well as pain) as in mouth opening (P=0.130), OHIP-14 (P=0.642), right temporalis muscles (P=0.384), left temporalis muscles (P=0.930), right masseter muscles (P=0.790), left masseter muscles (P=0.064), right trapezius muscle (P=0.403), and left trapezius muscle (P=0.058) among groups where (P>0.05). While after-treatment and follow up , there were significant statistical differences were P value was (P<0.05), in mouth opening (P=0.0001 and P=0.0001, respectively), OHIP-14 (P=0.0001 and P=0.0001, respectively), right temporalis muscles (P=0.035 and P=0.020, respectively), left temporalis muscles (P=0.0001 and P=0.0001, respectively), right masseter muscles (P=0.001 and P=0.0001, respectively), left masseter muscles (P=0.004 and P=0.035, respectively), right trapezius muscle (P=0.0001 and P=0.0001, respectively), and left trapezius muscle (P=0.031 and P=0.001, respectively) between groups. Conclusion: Both Muscle energy technique and global postural exercise program improved mouth opening, pressure pain threshold, as well as quality of life in temporomandibular joint disorders patients, with the superiority of muscle energy technique over global postural exercise program.
