“…It is assumed that post-needling soreness is thought to be a consequence of the neuromuscular damage generated by the consecutive needling insertions into the muscle 45. This hypothesis has been supported by a recent study showing that muscle damage identified by magnetic resonance imaging after the application of dry needling over the gastrocnemius muscle was associated withpost-needling induced-pain 46. Other authors have associated the presence of post-needling to the number of local twitch responses elicited during the needling therapy 47…”

Myofascial pain syndrome is a pain condition characterized by the presence of trigger points. Current evidence, mostly experimental studies, clearly supports a role of trigger points on peripheral and central sensitization since they are able to contribute to sensitization of peripheral nociceptors, spinal dorsal horn neurons, and the brainstem. Several interventions are proposed for treating trigger points, dry needling being one of the most commonly used by clinicians. There is no consensus on the clinical application of trigger point dry needling: some authors propose that local twitch responses should be elicited during the needling intervention to be effective, whereas others do not. The application of trigger point dry needling is able to reduce the excitability of the central nervous system by reducing peripheral nociception associated to the trigger point, by reducing dorsal horn neuron activity, and by modulating pain-related brainstem areas. However, the effects are mainly observed in the short-term, and effect sizes are moderateto small. Therefore, the current review proposes that the application of trigger point dry needling should be integrated into current pain neuroscience paradigm by combining its application with pain neuroscience education, graded exercise and manual therapy. Additionally, patient’s expectations, beliefs, previous experiences and patient–clinician interaction should be considered when integrating trigger point dry needling into a comprehensive treatment approach.

“…The automatic sympathetic neuron activation during the acupuncture intervention has also been correlated to the production of NO or vasoactive neuropeptides to modulate the vasodilation of the blood vessel to enhance the local blood volume (Jänig & Lisney, 1989; Kashiba & Uedo, 1991). In the other perspective, a consistent effort was on finding the anatomy acupoint sites in the meridian channel, by correlating to facial trigger points (Melzack et al ., 1977; Baraja-Vegas et al ., 2019), skin resistance (Ahn et al ., 2008), and interstitial flow (Zhang et al ., 2015). Among these attempted explanations, the neuron activation for both central nervous system and sympathetic nervous system is believed to be a clue to understand the acupuncture.…”

Acupuncture, though with debatable mechanisms, has been widely used as an alternative therapy for many diseases such as pain symptoms, systematic inflammation, etc. But current mechanisms based on neuron excitation, microcirculation, and acupoint anatomy cannot fully explain the physiological processes in acupuncture. In this work, the physiology of acupuncture is demonstrated by modeling the effects of a magnetic needle inserted into muscle tissue with a 2D frame. It has been found that active oxygen (O2) transport carried by interstitial flow is enhanced with the intervention of a magnetic needle. During needle retention, the magnetic needle generates a high gradient magnetic field around the tip, which exerts a strong force on the diamagnetic interstitial fluid to further accelerate the flow. This interstitial flow strongly correlates to the magnetic flux density B0 of the needle and tissue permeability. Moreover, it is found that the needle stirs the interstitial flow leading to redistribution of O2, and can pump O2 flux by 1-2 orders of magnitude compared to that without magnetic field. Furthermore, the enhancement of active O2 transport by magnetic needle is site-specific to the tissue in the vicinity of the tip. This enhancement is more effective in edema condition, which usually possesses a higher tissue permeability (>10−9 m2), than that in healthy condition. Based on the findings above, a general physiological mechanism of acupuncture is proposed based on the stimulated active O2 transport to mitochondria.Key pointsMagnetic needle provides high gradient magnetic field force on water molecules due to their diamagnetic property;Interstitial flow is driven by the high magnetic force and triggers active O2 transport in tissue with high permeability (specific hydraulic conductance);By modeling, the flux of O2 transport to mitochondria can be enhanced by more than 1-2 orders of magnitude due to the stirring effect of needle on the interstitial flow during acupuncture treatment;Physiological mechanism of acupuncture is proposed based on the dramatic enhancement of O2 transport to mitochondria by needle intervention.

Introduction: Despite the existence of some theories about the effect of Dry Needling on pain, there is still a lack of research using this technique in the treatment of temporomandibular disorder and its repercussions on the autonomic nervous system. Therefore, the aim was to analyze the effect of Dry Needling on the autonomic modulation of university students with temporomandibular disorders. Methods: This is an interventional, inferential study, carried out with university students with temporomandibular disorders. A frequency meter was used before, during, and after the application of the dry needle to verify its short and medium term effect on the autonomic nervous system. For statistical analysis, the ANOVA test was used. Results: Twenty volunteers with an average age of 21.3 years took part in the study, most of them male (65%). When the rMSSD and pNN50 indexes were analyzed, an increase was observed during dry needling (p = 0.701 and 0.452, respectively). However, after application, these indices fell, remaining above the base values. However, the triangular RR and TINN indices showed a constant increase during collection (p = 0.578 and 0.613, respectively). The high frequency component increased during the technique (p = 0.860), but the same did not happen with the low frequency component (p = 0.693), which suffered a constant increase, even with minor variation. Conclusion: The effect of this technique promotes the improvement of the heart rate variability values, maintaining the balance of the autonomic nervous system without generating cardiovascular risks, and its effects were immediate and lasting.
