Abstract Introduction Myofascial pain is one of the most common musculoskeletal pathologies in humans, with the presence of myofascial trigger points (MTrPs). A MTrP is defined as a hyperirritable nodule in a taut band of musculoskeletal fibers. The pain pressure threshold is a tool for the assessment of pain used in humans with proven reliability, however there is no evidence of the same in the study of MTrPs in horses. Aims The aim of this study was to evaluate the reliability of the measurement of pressure pain sensitivity in horses with MTrPs in the brachiocephalicus muscle. A second aim was to calculate the minimum detectable change (MDC) for this result. Material and Methods Twenty horses were evaluated, aged between five and fifteen years old. All without pathology or previous pharmacological treatment. The cranial angle of the scapula was taken as the anatomic reference. A first evaluator, whose reliability was already confirmed, performed a manual palpation of the distal aspect of the brachiocepalicus muscle. A MTrP was located in all animals included in the study. The anatomic reference and the MTrP were marked. The pain pressure threshold of the MTrP was measured using a pressure algometer (Wagner Instruments, EE.UU., kg/cm2). The same evaluator applied the tip of the algometer parallel to the neck and transversal to the muscle fibers, gradually increasing pressure until the ‘jump sign’ or facial expressions of pain were detected by a second operator who also recorded the measurements. The measurements were repeated consecutively twice in this manner. The first operator was blind to the measurements. The intraclass correlation index (ICC) was calculated to evaluate reliability. Results The mean thresholds of pain pressure sensitivity registered for the first and second measurement were 3.29 (1.0) kg/cm2 and 3.31 (0.9) kg/cm2. The ICC was 0.86 (95% CI: 0.68 to 0.95). The MDC was 0.9 kg/cm2 (95% CI: 0.6 to 1.4). Conclusions Acceptable reliability was found for the measurement of the pain pressure threshold in horses with MTrPs in the brachiocephalicus muscle.

Dry Needling (DN) is a technique indicated to treat injuries of muscle origin and widely used in the deactivation of myofascial trigger points (PGMs). Its application almost always produces immediate effect, decreasing pain and increasing range of motion. The main objective of the present study was to verify the effectiveness of Dry Needling in the deactivation of myofascial trigger points. A search was carried out through three distinct databases and 10 articles dating from the last ten years were selected, with a score greater than or equal to six, in the classification of the PEDro platform (Physiotherapy Evidence Database). All selected articles were classified as randomized controlled trials, where eight are blind randomized clinical trials and two double blind randomized clinical trials. Outcomes ranged from decreased trigger points, increased range of motion, pain intensity and pain pressure threshold. The studies included in this review suggest that Dry Needling has a fundamental role in the treatment of PGMs, mainly increasing the pressure pain threshold, thus suggesting trigger point deactivation.

Abstract Background Myofascial trigger point (MTrP) plays a major role in the genesis of mechanical neck pain, which may lead to chronic disorders. The purpose of the study is to investigate and compare the effect of ice massage plus integrated neuromuscular inhibition technique (INIT) versus INIT alone on active trigger points in the upper trapezius of persons having mechanical neck pain. Forty participants diagnosed as mechanical neck pain with upper trapezius active myofascial trigger points. They were randomized into two equal groups. Group A (experimental) received ice massage for 10 min plus INIT, while group B (control) received INIT alone. The treatment program continued for 2 weeks (3 sessions/week). The outcome measures are the pain intensity, pain pressure threshold, cervical lateral side bending and neck daily functions. Results The results showed that there were significant improvements in VAS at p = .899 and F = .78, PPT at p = .288 and F = .553, cervical side bending at p = .094 and F < 0.00001, and NDI at p = .164 and F = 0.00001 in both groups, while there were no statistically significant differences between both groups as p > 0.05. Conclusion Ice massage and INIT are effective methods in managing active trigger points in the upper trapezius of persons having mechanical neck pain without statistically significant difference.

Abstract Background This study aimed to investigate the effects of ischemic compression treatment (ICT) and low-level laser therapy (LLLT) applied on the trigger points of the infraspinatus muscle on shoulder pain and function in patients with shoulder pain. Methods Thirty patients with shoulder pain were randomly categorized into the ICT group (n = 15) and LLLT groups (n = 15). ICT was performed on three myofascial trigger points (MTrPs) of the infraspinatus muscle twice a week for 4 weeks (eight sessions), with 5 minutes of treatment per trigger point. LLLT was performed similarly. Shoulder pain was assessed using the visual analogue scale (VAS) and pain pressure threshold (PPT), and shoulder function was assessed using the Korean Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, rotator cuff strength, and range of motion (ROM) of shoulder flexion and abduction. Results Significant changes in VAS score and PPT were found after the intervention in both groups (p < 0.05). Significant changes were observed in the Korean DASH score, rotator cuff strength, and ROM of shoulder flexion (p < 0.05) but not in the ROM of shoulder abduction (p < 0.05). There were no significant differences between the two groups. Conclusion This study showed that both ICT and LLLT applied on the MTrPs of the infraspinatus muscle were effective for relieving shoulder pain and improving shoulder functions in patients with shoulder pain.

Ultrasound at a frequency of 1 or 3 MHz is frequently used to treat various musculoskeletal conditions, but research on ultrasound operating at 38-50 kHz frequencies (US-KHz) is lacking. Study aimed to evaluate the short-term effect of US-KHz on pain pressure threshold (PPT), ankle dorsiflexion range of motion (ROM), and motor performance (the Side Hop Test) in subjects with a myofascial trigger point (TrP) in the calf muscle. US-KHz was applied to the area of the palpable TrP in the calf muscle for 10 minutes (continuous pulse, transducer head size 19.6 cm2, power 0.75-1.25 w/cm2) in twenty volunteers (18-45 years old). Significant improvements (p<0.001) were noted in the Side Hop Test 24 hours after the intervention. ROM improved significantly after 5 minutes with changes maintained 24 hours later. No change was found in the PPT. This pilot study presents preliminary evidence of the efficacy of US-KHz in treating TrPs. Doi: 10.28991/SciMedJ-2021-0303-5 Full Text: PDF

Pain perception threshold (PFT) in the head was assessed with a pressure algometer in 58 cluster headache (CH) patients (52M, 6F; 41 episodic and 17 chronic). Fourteen patients in cluster period were retested in remission. Thresholds were assessed at 10 symmetrical points on each side of the head and at the deltoid. Compared with controls ( n = 80), CH patients had lower PPT in the head and in the deltoid. PPT was lower on the symptomatic side than on the non-symptomatic side in patients with episodic CH during a cluster period ( p<0.001) and in patients with chronic CH ( p<0.05). This pattern was more evident during a cluster period than during remission ( p<0.05). A reduced PPT did not correlate with illness duration and pain side. The lowest PPT mean values were found at the anterior and intermediate levels of the temporal muscle on the symptomatic side. These results imply a central mechanism underlying the pathogenesis of CH.

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.
