Abstract
The most common cause of chronic musculoskeletal pain is chronic myofascial pain syndrome (MPS). MPS often presents with increased muscle stiffness, and the myofascial trigger point (MTrP). Imaging modalities have been used to identify the MTrP, but their role in the detection and diagnosis of MPS remains unclear. The purpose of this review was to identify evidence in literature for the use of imaging in the role of classifying and explaining the physiology of MTrPs. Since few imaging techniques have been performed on MTrPs, we explored the imaging techniques that can effectively image complex skeletal muscle microstructure, and how they could be used. As part of a scoping review, we conducted a systematic search from three medical databases (CINAHL, EMBASE and MEDLINE) from year to year to analyze past MTrP imaging, as well as analyzing imaging techniques performed on the microstructure of muscle. Previously, ultrasound has been used to differentiate active, latent MTrPs, but these studies do not adequately address their underlying anatomical structure. MRI remains the standard method of imaging skeletal muscle. The existing MRI literature suggests that the DTI technique can quantify muscle injury, strain, and structure. However, theoretically, HARDI and DKI techniques seem to provide more information for complex structural areas, although these modalities have a disadvantage of longer scan times and have not been widely used on skeletal muscle. Our review suggests that DTI is the most effective imaging modality that has been used to define the microstructure of muscle and hence, could be optimal to image the MTrP. HARDI and DKI are techniques with theoretical potential for analysis of muscle, which may provide more detailed information representative of finer muscle structural features. Future research utilizing MRI techniques to image muscle are necessary to provide a more robust means of imaging skeletal muscle and the MTrP.

Interrater and Intrarater Reliability and Minimum Detectable Change of Ultrasound for Active Myofascial Trigger Points in Upper Trapezius Muscle in Individuals With Shoulder Pain. J Manipulative Physiol Ther 2020; 43:855-863. [PMID: 32863059 DOI: 10.1016/j.jmpt.2020.01.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2019] [Revised: 01/14/2020] [Accepted: 01/29/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVE We sought to investigate the interrater and intrarater reliability of ultrasound and the minimum detectable change (MDC) for the trigger points (TrPs) active in the upper trapezius (UT) muscle in individuals with shoulder pain. METHODS Forty individuals with shoulder pain were investigated for the presence of active TrPs in the UT muscle by means of ultrasound for the parameters of gray scale, muscle thickness of UT muscle at rest, and contraction and area of TrPs. The intrarater reliability was performed on 2 days, and interrater reliability on the same day. For the gray scale, the reliability was evaluated using the kappa coefficient (κ), while the other parameters were measured by the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and MDC. RESULTS For the gray scale, the intrarater agreement was almost perfect (κ = 1.00) and the interrater agreement was substantial (κ = 0.75). The intrarater and interrater reliability were excellent for most of the parameters, except for the area of TrPs (intrarater: ICC = 0.71, substantial; interrater: ICC = 0.52, substantial). The MDC for intrarater reliability varied between 0.04 and 0.05 (SEM% between 2.4% and 38.87%), and that for interrater reliability ranged from 0.05 to 0.07 (SEM% between 3.18% and 55.10%), with a higher value for area. CONCLUSION Parameters such as gray scale, resting muscle thickness, and muscle contraction of the UT muscle, obtained through ultrasound, showed excellent intrarater and interrater reliability with low SEM%. The intrarater and interrater reliability for the area deserves a caveat regarding their use.

Abstract
OBJECTIVE To systematically review current literature to determine the effectiveness of the ischemic compression (IC) technique on pain and function in individuals with shoulder pain. METHODS This review was conducted according to recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Cochrane Collaboration for Systematic Reviews; a search was performed in the electronic databases PubMed, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus, Physiotherapy Evidence Database, and Web of Science. Randomized clinical trials and quasi-randomized clinical trials were included, and the methodological quality was evaluated through the Physiotherapy Evidence Database scale. RESULTS The search found 572 studies; of these, 71 were selected by title and, subsequently, 29 were selected through abstract analyses. After critical analyses, 5 studies were included. The methodological quality ranged from 4 (reasonable) to 9 (excellent) points. Pain was assessed by all studies using the visual analog scale, Global Perceived Effect scale, Numerical Rating Scale, pressure pain threshold, or Perceived Amelioration Numerical Scale. Function was evaluated by 3 studies through the Shoulder Pain and Disability Index; Neck Disability Index; American Shoulder and Elbow Surgeons Standardized Shoulder Assessment; and Disabilities of the Arm, Shoulder, and Hand questionnaires. The studies showed that the IC technique produces immediate and short-term positive effects for pain, and positive short-term effects for shoulder function in individuals with shoulder pain. CONCLUSION The IC technique seems to be beneficial for pain and shoulder function. However, caution is needed when considering this evidence owing to the limited quality of some studies, the few articles found, and the lack of standardization of the application parameters of the technique to facilitate its reproducibility.

Abstract
OBJECTIVE To systematically scope the reported advice and education in physical therapy management of patients with subacromial shoulder pain, and to define key themes of the advice and education. DESIGN Scoping review. LITERATURE SEARCH We searched MEDLINE, Scopus, Web of Science, and CINAHL, with publication dates from 2007 to September 2019. STUDY SELECTION CRITERIA We included quantitative and qualitative research that reported on physical therapy interventions for subacromial shoulder pain. DATA SYNTHESIS We performed a qualitative synthesis that identified items included in patient advice and education. RESULTS Of 89 original studies included, there were 61 randomized controlled trials; 5 prospective studies; 16 nonrandomized observational intervention studies or case series; and 7 surveys, audits of physical therapy patient records, and focus groups with physical therapists. We identified 7 key themes for advice and education: exercise intensity and pain response, activity modification advice, posture advice, pain self-management advice, pathoanatomical and diagnosis information, behavioral approaches, and pain biology advice. CONCLUSION While advice focused predominantly on the local tissue pathology model, 10% of studies included information about pain neuroscience education, psychosocial factors, motor imagery, or behavior change.

Abstract
Background: Nonspecific shoulder pain has a high prevalence in older adults and causes functional alterations. Furthermore, there are difficulties in establishing a clinical diagnosis, effective treatments are lacking, and little evidence has been found regarding the use of invasive physical therapy techniques in this age group. Purpose: To determine the efficacy of a single physical therapy intervention with deep dry needling (DDN) on latent and active myofascial trigger points (MTrPs) in older adults with nonspecific shoulder pain. Methods: This pilot study is a single-blind, randomized, controlled clinical trial that included 20 participants, aged 65 years and older, who were diagnosed with nonspecific shoulder pain. The study was approved by the Clinical Research Ethics Committee of the area. Participants were recruited at their homes or at a care center and were randomly assigned into either an experimental group (n = 10), which received a session of DDN on 1 active and 1 latent MTrP of the infraspinatus muscle, or a control group (n = 10), which received a session of DDN on only 1 active MTrP. A blind examiner assessed the pain intensity, pain pressure threshold on the anterior deltoid, and extensor carpi radialis brevis muscles and grip strength before, immediately after, and 1 week after the intervention. Results: Statistically significant differences (P < .05) in the pressure pain thresholds (PPTs) of the extensor carpi radialis brevis were found in the experimental group in both posttreatment assessments. Moreover, the effect size values (d Cohen) varied from small for grip strength (0.017-0.36) to moderate for the pain intensity (0.46-0.78) and PPT in the anterior deltoid (0.49-0.66) and to large for the PPT in the extensor carpi radialis brevis (1.06-1.58). Conclusions: A single physical therapy intervention with DDN on 1 latent MTrP, in conjunction with 1 active MTrP, in the infraspinatus muscle may increase the PPT of the extensor carpi radialis brevis muscle area immediately following and 1 week after the intervention in older adults with nonspecific shoulder pain.

Abstract
Study Design Multicenter, parallel randomized clinical trial. Background Myofascial trigger points (MTrPs) are implicated in shoulder pain and functional limitations. An intervention intended to treat MTrPs is dry needling. Objectives To investigate the effectiveness of dry needling in addition to evidence-based personalized physical therapy treatment in the treatment of shoulder pain. Methods One hundred twenty patients with nonspecific shoulder pain were randomly allocated into 2 parallel groups: (1) personalized, evidencebased physical therapy treatment; and (2) trigger point dry needling in addition to personalized, evidence-based physical therapy treatment. Patients were assessed at baseline, posttreatment, and 3-month follow-up. The primary outcome measure was pain assessed by a visual analog scale at 3 months, and secondary variables were joint range-of-motion limitations, Constant-Murley score for pain and function, and number of active MTrPs. Clinical efficacy was assessed using intention-to-treat analysis. Results Of the 120 enrolled patients, 63 were randomly assigned to the control group and 57 to the intervention group. There were no significant differences in outcome between the 2 treatment groups. Both groups showed improvement over time. Conclusion Dry needling did not offer benefits in addition to personalized, evidencebased physical therapy treatment for patients with nonspecific shoulder pain. Level of Evidence Therapy, level 1b.

Abstract
Dry needling is a therapeutic intervention that has been growing in popularity. It is primarily used with patients that have pain of myofascial origin. This review provides background about dry needling, myofascial pain, and craniofacial pain. We summarize the evidence regarding the effectiveness of dry needling. For patients with upper quarter myofascial pain, a 2013 systematic review and meta-analysis of 12 randomized controlled studies reported that dry needling is effective in reducing pain (especially immediately after treatment) in patients with upper quarter pain. There have been fewer studies of patients with craniofacial pain and myofascial pain in other regions, but most of these studies report findings to suggest the dry needling may be helpful in reducing pain and improving other pain related variables such as the pain pressure threshold. More rigorous randomized controlled trials are clearly needed to more fully elucidate the effectiveness of dry needling.

Abstract
OBJECTIVES To identify the presence of myofascial trigger points (TrPs) and pressure pain threshold (PPT) levels in the shoulder muscles of both involved and uninvolved sides in patients with unilateral shoulder impingement syndrome (SIS). METHODS Twenty-seven patients with SIS and 20 matched control patients participated in this study. TrPs of 10 shoulder muscles and 8 PPTs, including tibialis anterior PPT, were assessed. RESULTS SIS group showed a greater number of TrPs (t=-2.697; P=0.010) than the control group. The muscles of the uninvolved side of the SIS group also presented some active TrPs. PPTs showed small differences between involved and uninvolved sides of patients with SIS and higher differences between both sides of the SIS group and dominant side of controls although with significant difference only in the supraspinatus PPT (F=3.239; P=0.045). The muscle PPTs of the patients presenting TrPs in each muscle of the involved side were lower than the PPTs of the patients without TrPs in the same muscle for both involved and uninvolved sides with few significant differences. DISCUSSION The high number of TrPs in the involved side of patients with SIS suggests the presence of peripheral sensitization. The results reject the presence of central alterations. Finally, the patients with unilateral SIS may present bilateral deficits related to myofascial pain.

Abstract
STUDY DESIGN Systematic review and meta-analysis. BACKGROUND Myofascial pain syndrome (MPS) is associated with hyperalgesic zones in muscle called myofascial trigger points. When palpated, active myofascial trigger points cause local or referred symptoms, including pain. Dry needling involves inserting an acupuncture-like needle into a myofascial trigger point, with the goal of reducing pain and restoring range of motion. OBJECTIVE To explore the evidence regarding the effectiveness of dry needling to reduce pain in patients with MPS of the upper quarter. METHODS An electronic literature search was performed using the key word dry needling. Articles identified with the search were screened for the following inclusion criteria: human subjects, randomized controlled trial (RCT), dry needling intervention group, and MPS involving the upper quarter. The RCTs that met these criteria were assessed and scored for internal validity using the MacDermid Quality Checklist. Four separate meta-analyses were performed: (1) dry needling compared to sham or control immediately after treatment, (2) dry needling compared to sham or control at 4 weeks, (3) dry needling compared to other treatments immediately after treatment, and (4) dry needling compared to other treatments at 4 weeks. RESULTS The initial search yielded 246 articles. Twelve RCTs were ultimately selected. The methodological quality scores ranged from 23 to 40 points, with a mean of 34 points (scale range, 0-48; best possible score, 48). The findings of 3 studies that compared dry needling to sham or placebo treatment provided evidence that dry needling can immediately decrease pain in patients with upper-quarter MPS, with an overall effect favoring dry needling. The findings of 2 studies that compared dry needling to sham or placebo treatment provided evidence that dry needling can decrease pain after 4 weeks in patients with upper-quarter MPS, although a wide confidence interval for the overall effect limits the impact of the effect. Findings of studies that compared dry needling to other treatments were highly heterogeneous, most likely due to variance in the comparison treatments. There was evidence from 2 studies that lidocaine injection may be more effective in reducing pain than dry needling at 4 weeks. CONCLUSION Based on the best current available evidence (grade A), we recommend dry needling, compared to sham or placebo, for decreasing pain immediately after treatment and at 4 weeks in patients with upper-quarter MPS. Due to the small number of high-quality RCTs published to date, additional well-designed studies are needed to support this recommendation. LEVEL OF EVIDENCE Therapy, level 1a-.

Abstract
Dry needling is a common treatment technique in orthopedic manual physical therapy. Although various dry needling approaches exist, the more common and best supported approach targets myofascial trigger points. This article aims to place trigger point dry needling within the context of pain sciences. From a pain science perspective, trigger points are constant sources of peripheral nociceptive input leading to peripheral and central sensitization. Dry needling cannot only reverse some aspects of central sensitization, it reduces local and referred pain, improves range of motion and muscle activation pattern, and alters the chemical environment of trigger points. Trigger point dry needling should be based on a thorough understanding of the scientific background of trigger points, the differences and similarities between active and latent trigger points, motor adaptation, and central sensitize application. Several outcome studies are included, as well as comments on dry needling and acupuncture.
