Deep dry needling (DDN) and percutaneous electrolysis (PE) provide the benefit of the mechanical effect of the needle, and PE adds the potential advantages of the galvanic current it incorporates in myofascial trigger points (MTrPs) therapy. The aim of this study was to compare the short-term efficacy between PE and DDN on active MTrPs of the levator scapulae by considering pain intensity. A simple-blind randomized controlled trial was carried out, recruiting patients suffering from non-specific neck pain lasting more than 3 months and with active MTrPs in the levator scapulae muscle (n = 52). Patients were divided into intervention (PE; n = 26) and control (DDN; n = 26) groups and received one treatment session on the active MTrPs of the levator scapulae. Patients were assessed for pain intensity, pressure pain threshold (PPT), cervical range of motion (CROM), neck disability and post-needling soreness, immediately after treatment, at 72 h and at 14 days. In addition, pain during treatment was recorded after the procedure. There were no significant differences for pain intensity, post-needling soreness and PPT. We found significant differences in CROM, immediately after treatment (p = 0.043), and at 72 h (p = 0.045), in favor of the PE group. Significant differences were found for neck disability (p < 0.047), immediately post-treatment, in favor of the DDN group. Moreover, there were significant differences for pain during the intervention (p < 0.002), in favor of the DDN group (4.54 ± 2.21) versus the PE group (6.54 ± 2.27). PE and DDN appear to have similar short-term effects. PE proved to be a more painful treatment than DDN. Clinical trial registry: NCT04157426.

Background Current research relates jaw clenching to athletic performance, in terms of force and agility. However, the impact of jaw clenching on sports accuracy is unclear. Objectives To analyse the impact of jaw position and chewing type on free-throw accuracy and electromyographic (EMG) activity of masticatory muscles during free-throws. Methods Cross-sectional study with 25 female basketball players aged 18–44. Each participant executed 18 free-throws under three different jaw conditions: mandibular rest, maximum intercuspation, and with interdental cotton rolls, in randomised order. Results Chewing type and jaw position were not associated with shooting accuracy (p = 0.106; p = 0.778). There was a positive correlation between EMG activity of the right masseter and free-throw accuracy at maximum intercuspation (rs = 0.402; p = 0.046). In contrast, negative correlations were found with other muscles when the occlusal vertical dimension was altered (rs = −0.619, p = 0.001; rs = −0.490; p = 0.013; rs = −0.534; p = 0.006). The chewing type affected the EMG of the left masseter in the altered occlusal vertical dimension (H = 6.969; p = 0.031). Significant differences in EMG recordings were observed across different mandibular positions during free-throws (p < 0.001). Conclusions While jaw positioning and chewing type do not impact free-throw accuracy in amateur female basketball players, the EMG activity of masticatory muscles is linked to shooting performance. This highlights the need for further research on motor behaviour of masticatory muscles in precision sports, especially for athletes using intraoral devices.
