A comparison of the muscular relaxation effect of TENS and EMG-biofeedback in patients with bruxism
PainSci summary of Wieselmann-Penkner 2001?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible. ★★★☆☆?3-star ratings are for typical studies with no more (or less) than the usual common problems. Ratings are a highly subjective opinion, and subject to revision at any time. If you think this paper has been incorrectly rated, please let me know.
This small test of TENS as a method of relaxing muscles compared TENS to EMG-biofeedback in 20 patients. Unfortunately, neither approach had any effect after 20 minutes of treatment: those jaw muscles kept right on clenching, as measured by EMG.
original abstract†Abstracts here may not perfectly match originals, for a variety of technical and practical reasons. Some abstacts are truncated for my purposes here, if they are particularly long-winded and unhelpful. I occasionally add clarifying notes. And I make some minor corrections.
This study investigated effects of electromyographic (EMG) biofeedback (BFB) and transcutaneous electrical neuromuscular stimulation (TENS) on the EMG activity of the masticatory muscles and skin conductance level (SCL) of patients, suffering from myofacial pain syndrome. In the course of the investigation, EMG activity as well as the SCL was measured after a 20 min BFB or, respectively, after a myomonitor session in 20 patients and pre- and post-treatment values were compared. Results showed tendencies of decreased mean-EMG levels for both groups after the treatment sessions, with higher EMG values for the myomonitor group. There was no indication of a significant decrease in mean EMG levels over the sessions. Furthermore, an increase of the SCL during the period of treatment was observed for both groups in session I and II, while session III produced nearly stable values. No existing correlations for changes in SCL and EMG-activity could be established.
