Objective. Some dry needling treatments involve repetitive and rapid needle insertions into myofascial trigger points. This type of treatment causes muscle injury and can also damage nerve fibers. The aim of this study is to determine the injury caused by 15 repetitive punctures in the muscle and the intramuscular nerves in healthy mouse muscle and its ulterior regeneration.Methods. We repeatedly needled thelevator auris longusmuscle of mice, and then the muscles were processed with immunohistochemistry, methylene blue, and electron microscopy techniques.Results. Three hours after the dry needling procedure, the muscle fibers showed some signs of an inflammatory response, which progressed to greater intensity 24 hours after the procedure. Some inflammatory cells could still be seen when the muscle regeneration was almost complete seven days after the treatment. One day after the treatment, some changes in the distribution of receptors could be observed in the denervated postsynaptic component. Reinnervation was complete by the third day after the dry needling procedure. We also saw very fine axonal branches reinnervating all the postsynaptic components and some residual sprouts the same day.Conclusion. Repeated dry needling punctures in muscle do not perturb the different stages of muscle regeneration and reinnervation.

Background: Myofascial trigger points (MTrPs) are hypersensitive nodules in a taut band (TB) of skeletal muscle. Dry needling (DN) is an invasive technique recommended for the treatment of MTrPs. However, to our knowledge, no studies have investigated the influence of the DN technique on modification of muscle stiffness and neurophysiological properties of MTrPs. Objective: The objective was to examine the effect of DN on muscle stiffness and motoneuron excitability of a latent medial MTrP (nodule and TB) of the soleus muscle in non-injured subjects. Methods: A double-blinded randomised controlled trial of 46 subjects with latent medial MTrPs of the soleus was conducted, in which all received one session of DN. The intervention group (n = 23) were subjected to DN into the MTrP (the nodule), while the control group (n = 23) were subjected to DN into the TB. Assessment was carried out at baseline (pre-test), after the intervention (post-test) and 1 week after the intervention (follow-up). Biomechanical variables (muscle resistive force at 10°/s and 180°/s, muscle extensibility and strength), as measured with an isokinetic dynamometer, and neurophysiological variables (H-reflex), were recorded. Results: There were no statistically significant differences in biomechanical or neurophysiological assessments between groups. Considering the intra-group analysis, subjects in the intervention group exhibited increased maximal isometric voluntary force to ankle plantarflexion (MIVFp) at both post-intervention and follow-up assessment (p < 0.0125; 0.2 < d < 0.5), while no changes were found in the control group. Conclusion: One session of DN targeting latent MTrPs did not change muscle stiffness, muscle extensibility or motoneuron excitability. Further research on subjects with muscle tone disorders should be considered to better address the impact of DN on muscle tone. Trial registration number: NCT02575586 (ClinicalTrials.gov).

Myofascial Trigger Points

Nyeri miofasial servikal (NMS) merupakan sumber nyeri umum pada individu dengan nyeri leher kronik nonspesifik. Nyeri dapat bersifat lokal, regional dan dapat juga memiliki banyak titik pemicu nyeri (myofascial trigger points/MTrPs). NMS menyebabkan nyeri di daerah otot servikal maupun fasia di sekitarnya. Nyeri leher menurunkan kualitas hidup, menurunkan produktivitas dan menyebabkan disabilitas sehingga berpengaruh secara sosioekonomi terhadap penderita dan masyarakat.Pengobatan sindrom nyeri miofasial servikal masih belum memuaskan terkait kronisitasnya. Dry needling (DN) adalah salah satu pilihan terapi nonfarmakologi yang bisa diterapkan pada NMS. DN akan mengurangi sensitisasi perifer dan sentral dengan menghilangkan sumber nosisepsi perifer (area MTrPs), memodulasi aktifitas kornu dorsalis dan mengaktifkan jalur inhibisi nyeri sentral.Neurolog sering menangani kasus NMS dan perkembangan DN akhir-akhir ini semakin pesat sebagai manajemen nyeri. Namun, keefektifan terapi DN masih belum jelas. Oleh karena itu, pengetahuan tentang peran DN pada NMS ini penting untuk diketahui oleh para neurolog. Artikel kami akan membahas tentang peran DN pada sindrom nyeri miofasial servikal.Kata kunci: Dry needling, nyeri miofasial servikal, terapi, myofascial trigger point

Procedures such as dry needling (DN) or percutaneous electrical nerve stimulation (PENS) are commonly proposed for the treatment of myofascial trigger points (MTrP). The aim of the present study is to investigate if PENS is more effective than DN in the short term in subjects with mechanical neck pain. This was an evaluator-blinded randomized controlled trial. Subjects were recruited through announcements and randomly allocated into DN or PENS groups. Pain intensity, disability, pressure pain threshold (PPT), range of motion (ROM), and side-bending strength were measured. The analyses included mixed-model analyses of variance and pairwise comparisons with Bonferroni correction. The final sample was composed of 44 subjects (22 per group). Both groups showed improvements in pain intensity (ηp2 = 0.62; p < 0.01), disability (ηp2 = 0.74; p < 0.01), PPT (ηp2 = 0.79; p < 0.01), and strength (ηp2 = 0.37; p < 0.01). The PENS group showed greater improvements in disability (mean difference, 3.27; 95% CI, 0.27–6.27) and PPT (mean difference, 0.88–1.35; p < 0.01). Mixed results were obtained for ROM. PENS seems to produce greater improvements in PPT and disability in the short term.

Abstract Aims To evaluate the anatomic variability of the gastrocnemius venous system using ultrasound and the overlap of the same with myofascial trigger points (MTrPs 1 and 2) clinically located in this muscle. Material and Methods In total, 82 legs of 41 healthy adults were studied, belonging to 26 men and 15 women aged between 22 and 50 years. The blood vessels located below MTrP1 and MTrP2, described by Travell and Simons were observed, and each image was analyzed by sectors (medial, central and lateral) to quantify the number of blood vessels, their distribution and overlap with the MTrPs described at this level. Results Examination of the 164 heads of 82 gastrocnemius muscles revealed that at least one vessel exists for each section analyzed. The number of veins per head varied between 1 and 8. The most common pattern in the medial gastrocnemius was three vessels (41.5%) and two vessels (49%) in the lateral gastrocnemius. In 100% of the cases the localization of the veins coincided with the clinical localization of the MTrPs. Conclusions The venous pattern of the proximal gastrocnemius is highly variable among subjects regarding the number of blood vessels and their distribution. There is a complete overlap between the clinical localization of the gastrocnemius MTrPs and the presence of blood vessels.

Background: Deep dry needling (DDN) and ischemic compression technic (ICT) may be considered as interventions used for the treatment of Myofascial Pain Syndrome (MPS) in latent myofascial trigger points (MTrPs). The immediate effectiveness of both DDN and ICT on pressure pain threshold (PPT) and skin temperature of the latent MTrPs of the triceps surae has not yet been determined, especially in athletes due to their treatment requirements during training and competition. Objective: To compare the immediate efficacy between DDN and ICT in the latent MTrPs of triathletes considering PPT and thermography measurements. Method: A total sample of 34 triathletes was divided into two groups: DDN and ICT. The triathletes only received a treatment session of DDN (n = 17) or ICT (n = 17). PPT and skin temperature of the selected latent MTrPs were assessed before and after treatment. Results: Statistically significant differences between both groups were shown after treatment, showing a PPT reduction (p < 0.05) in the DDN group, while PPT values were maintained in the ICT group. There were not statistically significant differences (p > 0.05) for thermographic values before and treatment for both interventions. Conclusions: Findings of this study suggested that ICT could be more advisable than DDN regarding latent MTrPs local mechanosensitivity immediately after treatment due to the requirements of training and competition in athletes’ population. Nevertheless, further studies comparing both interventions in the long term should be carried out in this specific population due to the possible influence of delayed onset muscle soreness and muscle damage on PPT and thermography values secondary to the high level of training and competition.

Background Treatment of active myofascial trigger points includes both invasive and non-invasive techniques. Objectives To compare the effects of upper trapezius trigger point dry needling (DN) and strain–counterstrain (SCS) techniques versus sham SCS. Study Design Randomised controlled trial. Method 34 study subjects with active trigger points were randomly assigned to one of three treatment groups, and received either three sessions of DN (n=12), six sessions of SCS (n=10), or sham SCS (n=12) over a 3-week period. Subjective pain response and subjects’ own ratings of perceived disability were measured. Results The analysis of variance mixed model showed a significant time effect for pain (p<0.001), elicited pain (p<0.001), pain pressure threshold (p<0.01), and neck disability index (p=0.016). Pain at rest decreased in all groups, as follows: DN 18.5 mm (95% CI 4.3 to 32.7 mm); SCS 28.3 mm (95% CI 12.4 to 44.1 mm); sham SCS 21.9 mm (95% CI 3.5 to 40.1 mm). Reductions in disability score (points) were significant in the SCS group (5.5, 95% CI 1.6 to 9.4) but not in the DN (1.4, 95% CI −4.9 to 2.1) or sham SCS (1.8, 95% CI −6.4 to 2.7) groups. There was no significant group×time interaction effect for any variables studied. Conclusions There were no differences between the sham SCS, SCS, and DN groups in any of the outcome measures. DN relieved pain after fewer sessions than SCS and sham SCS, and thus may be a more efficient technique. Future studies should include a larger sample size. Trial Registration Number NCT01290653.
