"The purpose of this study was to assess the effect of a single 60 min TENS application on sEMG and kinesiographic activity in TMD patients in remission, and to assess the sEMG and kinesiographic effect of TENS in placebo and untreated groups. Sixty female subjects, selected according to the inclusion\/exclusion criteria, suffering from unilateral TMD in remission were assigned to one of the following group: Group TENS, that received a single session of 60 min of TENS; Group Placebo that received a single session of 60 min of sham TENS; Group Control, that received no treatment. Pre- and post-treatment differences in sEMG of TA, MM, SCM, and DA and interocclusal distance values within groups were tested using the Wilcoxon test. Differences in sEMG and kinesiographic data, among the three groups, were assessed by Kruskal-Wallis test. Significant differences were only observed in the TENS group, for masticatory muscles of both sides; one-way analysis of variance revealed that sEMG values of masticatory muscles of both sides in the TENS group were significantly reduced, in comparison with placebo and control groups. Kinesiographic results showed that the vertical component of the interocclusal distance was significantly increased after TENS only in the TENS group. TENS could be effective to reduce the sEMG activity of masticatory muscles and to improve the interocclusal distance of TMD patients in remission; the placebo effect seems not present in the TENS application.. .

Abstract

"The purpose of this study was to assess the effect of a single 60 min TENS application on sEMG and kinesiographic activity in TMD patients in remission, and to assess the sEMG and kinesiographic effect of TENS in placebo and untreated groups. Sixty female subjects, selected according to the inclusion\/exclusion criteria, suffering from unilateral TMD in remission were assigned to one of the following group: Group TENS, that received a single session of 60 min of TENS; Group Placebo that received a single session of 60 min of sham TENS; Group Control, that received no treatment. Pre- and post-treatment differences in sEMG of TA, MM, SCM, and DA and interocclusal distance values within groups were tested using the Wilcoxon test. Differences in sEMG and kinesiographic data, among the three groups, were assessed by Kruskal-Wallis test. Significant differences were only observed in the TENS group, for masticatory muscles of both sides; one-way analysis of variance revealed that sEMG values of masticatory muscles of both sides in the TENS group were significantly reduced, in comparison with placebo and control groups. Kinesiographic results showed that the vertical component of the interocclusal distance was significantly increased after TENS only in the TENS group. TENS could be effective to reduce the sEMG activity of masticatory muscles and to improve the interocclusal distance of TMD patients in remission; the placebo effect seems not present in the TENS application.. .
