Short-term transcutaneous electrical nerve stimulation reduces pain and improves the masticatory muscle activity in temporomandibular disorder patients: a randomized controlled trial

Abstract: Studies to assess the effects of therapies on pain and masticatory muscle function are scarce. Objective To investigate the short-term effect of transcutaneous electrical nerve stimulation (TENS) by examining pain intensity, pressure pain threshold (PPT) and electromyography (EMG) activity in patients with temporomandibular disorder (TMD).Material and Methods Forty patients with myofascial TMD were enrolled in this randomized placebo-controlled trial and were divided into two groups: active (n=20) and placebo … Show more

“…Out of the 42 RCTs, sample size ranged from 13 20 to 99 21 with a total of 1657 patients, mostly women, that is from 47 22 up to 100% 23-31 of the sample.

“…ES as a new and developing treatment has been applied in clinical settings for many years. Ferreira et al [19] found that the temporomandibular disorder treatment process, ES mitigated pain and improved masticatory muscle activity efficiently, without drugs or the need for invasive procedures. Rajfur et al [10] found that electrical therapy was effective in treating chronic low back pain.…”

“…Ferreira.et al [15,28] proved that the therapeutic effects of TENS are superior to those of the placebo. In recent years, several RCTs compared LLLT with TENS for treating patients suffering from TMD [10,12,14,29].…”
