Objective: The purpose of this study was to assess the efficacy of a myofascial release (MR) protocol applied with a transcutaneous electrical nerve stimulation (TENS) conductive glove.

Methods: Eighty individuals with neck myofascial syndrome were randomly divided into 4 groups: (1) MR protocol with a TENS conductive glove (MR+TENS), (2) MR protocol without TENS (MR), (3) conventional TENS protocol (TENS), and (4) placebo TENS (control). All participants attended 6 sessions over a period of 3 weeks. The following measures were evaluated at baseline, at the third week, and at the 1-month follow-up: Pain with the visual analog scale (VAS pain), upper trapezius pressure pain threshold (PPT) with pressure algometry, cervical range of motion (ROM) with goniometry, and disability with the neck disability index (NDI). A 2-way ANOVA with repeated measurements was applied.

Results: Significant changes between the 3 intervention groups and the control group were noted in the VAS and the NDI scores (P < .05) with the MR+TENS group exhibiting the biggest difference. Additionally, MR significantly increased PPT compared to TENS, and even further when applied with the conductive glove (P < .05). Regarding lateral flexion ROM, MR was equally effective either alone or in combination with the glove compared to TENS (P < .05). In contrast, TENS did not appear to affect neck PPT and ROM (P > .05). Finally, no difference between the groups was detected in cervical rotation ROM (P > .05).

Conclusion: The MR protocol appears to be more effective in dealing with pain, disability, and lateral flexion ROM than conventional TENS. A TENS conductive glove significantly improves the effects of MR, possibly due to the combined mechanical and electrical stimulation of the muscle.
