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.

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.

Abstract Objective Myofascial pain syndrome is one of the primary causes of health care visits. In recent years, physical exercise programs have been developed for the treatment of myofascial trigger points, but their effect on different outcomes has not been clarified. Thus, this study aimed to assess the effect of physical exercise programs on myofascial trigger points. Methods A systematic search was conducted in Pubmed, Web of Science, and Scopus. Articles analyzing the effect of physical exercise programs on pain intensity, pressure pain threshold, range of motion, and disability were included. Risk of bias was assessed using the Cochrane RoB2 tool. The DerSimonian-Laird method was used to compute the pooled effect sizes (ES) and their 95% confidence interval (95% CI) for pain intensity, pressure pain threshold, range of motion, and disability. Results A total of 24 randomized controlled trials were included in this systematic review and meta-analysis. The pooled ES were –0.47 (95% CI = –0.61 to –0.33) for pain intensity, 0.63 (95% CI = 0.31 to 0.95) for pressure pain threshold, 0.43 (95% CI = 0.24 to 0.62) for range of motion, and –0.18 (95% CI = –0.45 to 0.10) for disability. Conclusions Physical exercise programs may be an effective approach in the treatment of pain intensity, pressure pain threshold, and range of motion among patients with myofascial trigger points.

Objective To investigate the therapeutic effectiveness of percutaneous fascia release to treat chronic recurrent gluteal myofascial pain related to recurrent tendonitis or bursitis at the attachment sites. Methods Five patients (three males, two females; aged 48.6 ± 8.9 years) with myofascial trigger points in the gluteus medius muscle were treated. Outcome measures, including pain intensity, pressure pain threshold, and the relative strength of hip abduction, were assessed before, immediately after, and six months after the treatment. The data measured before and after treatment (different times) on visual analog scale, pressure pain threshold, and relative hip abduction strength were analyzed by Wilcoxon signed-rank test and paired t-test, respectively, for the comparisons between time points. Results Reduction in pain intensity and increase in the pressure pain threshold and the relative hip abduction strength were found in all five patients after treatment when compared with those of before treatment ( P < 0.05). Moreover, all of these improvements existed for at least six months ( P > 0.05). Conclusions Percutaneous fascia release of gluteal muscle insertion sites can be used to treat chronic gluteal pain related to subtrochanteric bursitis to avoid recurrence, if other treatment cannot control the recurrence, although this was demonstrated only on a small sample size without control and blind assessment in the pilot study.

Objective. The purpose of this pilot study is to investigate the effectiveness of the percutaneous soft tissue release for the treatment of recurrent myofascial pain in the forearm due to recurrent lateral epicondylitis.Methods. Six patients with chronic recurrent pain in the forearm with myofascial trigger points (MTrPs) due to chronic lateral epicondylitis were treated with percutaneous soft tissue release of Lin’s technique. Pain intensity (measured with a numerical pain rating scale), pressure pain threshold (measured with a pressure algometer), and grasping strength (measured with a hand dynamometer) were assessed before, immediately after, and 3 months and 12 months after the treatment.Results. For every individual case, the pain intensity was significantly reduced(P<0.01)and the pressure pain threshold and the grasping strength were significantly increased(P<0.01)immediately after the treatment. This significant effectiveness lasts for at least one year.Conclusions. It is suggested that percutaneous soft tissue release can be used for treating chronic recurrent lateral epicondylitis to avoid recurrence, if other treatment, such as oral anti-inflammatory medicine, physical therapy, or local steroid injection, cannot control the recurrent pain.

Painful Knee

Osteoarthritis (OA) is the most common joint disorder in the world. Among the mechanisms involved in osteoarthritis, biomarkers (cytokines profile) may be related to pain and pain intensity, functional capacity, and pressure pain thresholds (PPT). Thus, the study of these relationships may offer useful information about pathophysiology and associated mechanisms involved in osteoarthritis. Therefore, the objective of this study was to investigate the seric concentration of pro (IL-6, IL-8, and TNF-α) and anti-inflammatory (IL-10) cytokines in patients with painful knee osteoarthritis and to correlate the levels of these biomarkers with the patients’ functional capacity and pressure pain threshold (PPT) values.

Objective: To assess clinical differences in the Achilles tendons of runners with ankle equinus wearing either compressive or standard stockings. Design: Case–control study. Methods: In this study, we conducted clinical examinations of 98 sportsmen (runners) with equinus, before and after 30 min of running on a treadmill; 49 runners wore compressive stockings and 49 wore standard stockings. Clinical assessments of the runners’ Achilles tendons were based on the pressure pain threshold (PPT) and skin temperature analysis. Results: Achilles tendon evaluations identified significant differences in skin temperature modification and PPT between the compressive and standard stocking groups. Conclusions: Based on our findings, we propose that higher skin temperatures are associated with lower pressure pain thresholds in the Achilles tendons of runners with ankle equinus.
