Objective: To compare the clinical effects of needling interventions eliciting local twitch responses (LTRs) versus needling without eliciting LTRs when applied to muscle trigger points (TrPs) associated with spinal pain of musculoskeletal origin. Databases and data treatment: Electronic databases were searched for randomized or non-randomized clinical trials where one group received needling intervention where LTRs were elicited and was compared with another group receiving the same intervention without elicitation of LTRs in spinal pain disorders associated with TrPs. Outcomes included pain intensity, pain-related disability, and pressure pain thresholds. The risk of bias (RoB) was assessed using the Cochrane risk of bias tool or ROBINS-I tool, methodological quality was assessed with the PEDro score, and quality of evidence was evaluated using the GRADE approach. Results: Six trials were included. The application of a needling intervention eliciting LTRs was associated with a significant reduction in pain intensity immediately after treatment (mean difference (MD): −2.03 points, 95% confidence interval (CI): −3.77 to −0.29; standardized MD (SMD): −1.35, 95% CI: −2.32 to −0.38, p = 0.02) when compared to the same needling intervention without elicitation of LTRs. No effect at short-term follow-up (MD: −0.20 points, 95% CI: −1.46 to 1.06, p = 0.75) was observed. No significant differences based on elicitation or non-elicitation of LTRs were found in related disability (SMD: −0.05, 95% CI: −0.41 to 0.30, p = 0.77) or pressure pain thresholds (MD: 23.39 kPa, 95% CI: −13.68 to 60.47, p = 0.22). Discussion: Low-level evidence suggests an immediate effect of obtaining LTRs during needling interventions on pain intensity, with no significant effects on related disability or pressure pain sensitivity in spinal pain disorders associated with muscle TrPs.

Masticatory Muscle Activity

Masticatory muscle pain (MMP) is the most prevalent source of pain related to temporomandibular disorders. Some authors suggest that MMP may be related to the presence of myofascial trigger points (TrPs). Aim. The aim of the present study was to evaluate the immediate effect of masseter (MM) trigger point compressions technique on masticatory muscle activity and pressure pain thresholds (PPT). Material and methods. The participants were 15 healthy adults (10 women and 5 men; mean age 23.1±3.6). All participants included into the study had unilateral latent trigger points (TrPs) in the masseter muscle. Compression technique (CoT) of the latent TrPs in the masseter muscle was performed by pressing with index finger using constant, calibrated pressure of 2 kg/cm2 on the TrPs for 90 seconds. The electrical activity of the examined muscles and pressure pain thresholds for masseter muscles were recorded prior and after CoT. Results. Mean surface electrical activity of the MM muscle with TrPs and both sides of digastric muscle (DA) during resting mandibular position after CoT was significantly lower than before CoT (mean differences: MM 1=-0.783, p=0.001; DA 1=-0.312, p=0.01; DA 2=-0.229, p=0.025). Mean PPT of the MM muscles with TrPs after CoT was significantly higher comparing to baseline (1.819 vs.1.529 kg, respectively; p=0.001). Conclusions. CoT of the TrPs in masseter muscle reduces masticatory muscles resting activity. The use of CoT applied to the TrPs in masseter muscle increases pain pressure threshold. CoT may be effective in the management of MMP. (Ginszt M, Berger M, Gawda P, Bożyk A, Gawda J, Szkutnik J, Suwała M, Majcher P, Kapelan M.

Abstract Background Pain sensitivity in chronic neck pain patients may be influenced by health conditions related to higher levels of widespread pressure pain hypersensitivity (sensitization). Trigger points have also been reported to play a role in the sensitization process. Objectives To investigate the association between pressure pain thresholds, trigger points, and health conditions in patients with chronic neck pain. Design Original research, preliminary study. Setting A private clinic. Subjects Thirty-four chronic mechanical neck pain patients and 34 chronic whiplash-associated neck pain patients, giving a final sample of 68 chronic neck pain patients. Methods Patients underwent an assessment of pressure pain thresholds over the upper trapezius, extensor carpi radialis longus, and tibialis anterior muscles and were screened for the presence of trigger points in the upper trapezius muscle. Further, information about health history conditions was obtained and collected in a form. Results Significantly negative correlations between all pressure pain thresholds and duration of health history conditions were found (all P < 0.02). Significantly lower pressure pain thresholds (all P < 0.01) were found in patients with active trigger points as compared with those with latent trigger points. Conclusion Widespread pressure pain hypersensitivity was associated with duration of health history conditions, suggesting that long-lasting health complaints may act as a triggering/perpetuating factor, driving sensitization in individuals with chronic neck pain. Active trigger points may be associated with higher widespread pressure hypersensitivity.

Background The purpose of this study was to develop an experimental model of myofascial trigger points to investigate their pathophysiology. Methods Fifteen healthy volunteers who gave informed consent underwent repetitive eccentric exercise of the third finger of one hand (0.1Hz repetitions, three sets at five minute intervals) until exhaustion. Physical examination, pressure pain threshold, and electrical pain threshold of the skin, fascia and muscle were measured immediately afterwards and for seven days. Needle electromyogram (EMG) was also recorded in a subgroup of participants. Results Pressure pain thresholds decreased to a minimum on the second day after the exercise, then gradually returned to baseline values by the seventh day. On the second day, a ropy band was palpated in the exercised forearm muscle and the electrical pain threshold of the fascia at the palpable band was the lowest among the measured loci and tissues. Needle EMG activity accompanied with dull pain sensation was recorded only when the electrode was located on or near the fascia of the palpable band on the second day of exercise. Conclusion These results suggest that eccentric exercise may yield a useful model for the investigation of the myofascial trigger points and/or acupuncture points. The sensitised nociceptors at the fascia of the palpable band might be a possible candidate for the localised tender region.
