Diaphragm and core stabilization exercises in low back pain: A narrative review. J Bodyw Mov Ther 2023; 36:221-227. [PMID: 37949564 DOI: 10.1016/j.jbmt.2023.07.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2021] [Revised: 05/03/2023] [Accepted: 07/04/2023] [Indexed: 11/12/2023]
Abstract
INTRODUCTION Core stabilization is a vital concept in clinical rehabilitation (including low back pain rehabilitation) and competitive athletic training. The core comprises of a complex network of hip, trunk and neck muscles including the diaphragm. AIMS The paper aims to discuss the role of the diaphragm in core stability, summarize current evidence and put forth ideal core training strategies involving the diaphragm. METHOD Narrative review RESULTS: The diaphragm has a dual role of respiration and postural control. Evidence suggests that current core stability exercises for low back pain are superior than minimal or no treatment, however, no more beneficial than general exercises and/or manual therapy. There appears to be a higher focus on the transversus abdominis and multifidi muscles and minimal attention to the diaphragm. We propose that any form of core stabilization exercises for low back pain rehabilitation should consider the diaphragm. Core stabilization program could commence with facilitation of normal breathing patterns and progressive systematic restoration of the postural control role of the diaphragm muscle. CONCLUSION The role of the diaphragm is often overlooked in both research and practice. Attention to the diaphragm may improve the effectiveness of core stability exercise in low back pain rehabilitation.

Abstract
BACKGROUND Determining the optimal number of dry needling (DN) sessions to satisfactorily treat a stroke patient with spasticity is important from both clinical and economic perspective. OBJECTIVE To explore the effects of one versus three sessions of DN on spasticity of the wrist flexors and motor recovery after stroke. METHODS In this single-blind randomized clinical trial, 24 patients were randomly and equally divided into two groups: one group received one session of DN, while the other group received three sessions of DN in one week. Both groups received one minute of DN of the flexor carpi radialis and flexor carpi ulnaris. The outcome measures were the Modified Modified Ashworth Scale (MMAS), passive resistance torque (PRT), wrist active and passive extension range of motion (ROM), and the Brunnstrom Stages of Stroke Recovery (BSSR) measured before, immediately after, and one week after the last DN session. RESULTS Both groups demonstrated a significant improvement in all outcomes (p < .05). The MMAS scores in both groups meaningfully improved (p < .001). No significant differences were found between the two groups; however, a significant time-by-group interaction was observed for the PRT (p = .02; Cohen's d = 0.23-0.73), wrist active extension ROM (p = .001; Cohen's d = 0.37-0.67), and wrist passive extension ROM (p = .02; Cohen's d = 0.32-1.30). The BSSR significantly improved from 3 to 4 in both groups (p < .001). CONCLUSION Administering three sessions of DN can effectively improve spasticity and motor function after stroke.

Intramuscular Electrical Stimulation for the Treatment of Trigger Points in Patients with Chronic Migraine: A Protocol for a Pilot Study Using a Single-Case Experimental Design. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1380. [PMID: 37629671 PMCID: PMC10456716 DOI: 10.3390/medicina59081380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 07/25/2023] [Accepted: 07/25/2023] [Indexed: 08/27/2023]
Abstract
Background and Objectives: Trigger points (TrPs) are prevalent in patients with migraine headaches. Needling interventions targeting TrPs in migraine patients may reduce the intensity and frequency of headaches, yet systematic reviews reveal a lack of robust evidence. Intramuscular electrical stimulation (IMES) is a modality that delivers electrical current into muscles and TrPs, with recent studies suggesting it may amplify the therapeutic effects of dry needling peripherally and centrally. This could be advantageous for patients with migraine and symptomatic TrPs. Materials and Methods: This study will implement a multiple baseline single-case experimental design (SCED). In a clinical setting, a SCED study lends itself to conducting research with only a few patients that each serve as their own controls. In this SCED study, four participants with chronic migraine will be enrolled in a non-concurrent manner and randomized to one of four baseline measurement periods (4, 5, 6 or 7 weeks), leading to four potentially different start dates for each participant in the intervention phase. During the intervention phase, patients will receive five sessions of dry needling with IMES, one session per week for five weeks. The primary outcome measure will be headache frequency, i.e., the reduction in the number of headache days over a one-month period using electronic headache diary data from the Migraine Buddy smartphone application. Secondary outcome measures will be changes in mean migraine pain intensity using a numeric pain rating scale (NPRS), migraine disability using the Migraine Disability Assessment Test (MIDAS), the Headache Impact Test (HIT-6), and changes in selected cervical musculoskeletal impairments including pressure pain thresholds (PPTs) over TrPs, the craniocervical flexion test (CCFT), and cervical active range of motion (AROM). Primary and secondary outcome measures will be analyzed separately using both visual and statistical analyses. Results: Actively recruiting participants. This project was approved by the Mass General Brigham Institutional Review Board (protocol #2023P000931) and is registered with ClinicalTrials.gov (NCT05893914). Conclusions: This study will seek to determine the effects of a five-week intervention period of IMES to TrPs in the posterior cervical muscles of subjects with chronic migraine.

Abstract
The click reaction between a functionalized trans-cyclooctene (TCO) and a tetrazine (Tz) is a compelling method for bioorthogonal conjugation in combination with payload releasing capabilities. However, the synthesis of difunctionalized TCOs remains challenging. As a result, these compounds are poorly accessible, which impedes the development of novel applications. In this work, the scalable and accessible synthesis of a new bioorthogonal difunctionalized TCO is reported in only four single selective high yielding steps starting from commercially available compounds. The TCO-Tz click reaction was assessed and revealed excellent kinetic rates and subsequently payload release was shown with various functionalized derivatives. Tetrazine triggered release of carbonate and carbamate payloads was demonstrated up to 100 % release efficiency and local drug release was shown in a cellular toxicity study which revealed a >20-fold increase in cytotoxicity.

Abstract
Background: In this case report of a 31-year-old female, we describe the effects of dry needling on scar tissue following total hip arthroplasty. Case report: A 31-year-old woman underwent an elective bilateral total hip replacement due to a motor vehicle accident. Based on physical examination, the patient had burning pain at the incision site at the time of menstruation and limited hip range of motion worse on the right side. The treatment program consisted of six sessions of dry needling over a three-week period alongside infrared radiation for 20 minutes during each session. The needles were spaced along the entire length of the scar tissue and rotation was performed back and forth across the scar region to release the adhesion between the scar line and the underlying tissue, focusing more on the painful-to-touch spots and adhesive points. Following the completion of the dry needling treatments hip range of motion and the patient's functional outcome improved. Dry needling may be an effective and rapid treatment for scar tissue adhesion after surgical procedures. High-quality randomized-controlled studies are needed to verify the efficacy of this method.

Abstract
BACKGROUND Spasticity is a common cause of disability in multiple sclerosis (MS), which can negatively affect the patient's walking and balance. OBJECTIVE To evaluate the immediate effect of dry needling (DN) on spasticity and mobility in a female with MS. CASE DESCRIPTION In this case, a 38-year-old female with a 4-year history of MS was treated. The hamstring muscles (biceps femoris and semitendinosus) were needled for 1 minute in a single session. The main outcome measures were the Modified Modified Ashworth Scale (MMAS) to evaluate spasticity, the Timed 25-Foot Walk (T25FW) for the assessment of mobility and leg function performance, and stiffness as a biomechanical index of spasticity measured by a dynamometer. The assessments were done before and immediately after DN. OUTCOMES The MMAS scores decreased in the hamstrings (1 to 0) and quadriceps (2 to 1). The mobility improved as the time for T25FW decreased from 16.30 to 9.29 seconds. The stiffness of hamstring decreased after treatment (0.451 to 0.312). CONCLUSION One session of DN for the hamstring muscle decreased spasticity and improved mobility in this patient with MS. Further studies are suggested.

Intramuscular Electrical Stimulation to Trigger Points: Insights into Mechanisms and Clinical Applications—A Scoping Review. J Clin Med 2022; 11:jcm11206039. [PMID: 36294360 PMCID: PMC9605351 DOI: 10.3390/jcm11206039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 10/07/2022] [Accepted: 10/10/2022] [Indexed: 11/21/2022] Open
Abstract
Intramuscular electrical stimulation (IMES) is a modality used by clinicians to treat myofascial pain. Recent studies have shown positive results for the use of IMES on pain outcomes, yet studies investigating the potential mechanisms of IMES directly to trigger points (TrPs) are lacking. We performed a scoping review of the literature to summarize the current evidence from human and animal studies on the mechanisms of IMES to the TrP location, and to identify gaps in the existing literature. Electronic literature searches were conducted across five databases from inception to 15 August 2022, including PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Allied and Complementary Medicine Database (AMED), Scopus and Cochrane Register of Controlled Trials. Four studies met our full criteria for inclusion in this review. Three studies assessed the effects of IMES to TrPs on human subjects with MPS, and only one study used an animal model with experimentally generated TrPs. Based on the results of the included studies, IMES within a TrP region was reported to normalize muscle blood flow, decrease endplate noise of the TrP and elicit antinociceptive effects, at least partially, through engaging supraspinal descending pain inhibitory systems. At present, no clinical implications can be determined on the use of IMES to TrPs due to the limited amount and quality of the available evidence. Further studies investigating the clinical effectiveness and also underlying mechanisms of IMES to TrPs are clearly needed.

Abstract
A recent study published in Diagnostics attempted to visualize trigger points and contracture knots with high-definition ultrasound. Based on their findings, the authors reversed the commonly understood meaning of the two terms. However, they did so without providing any convincing evidence. The authors maintained that their sonography images represented trigger points within contracture knots, supporting the multiple loci hypothesis. On review of the paper, both conclusions seem premature and rather speculative.

Spinopelvic alignment and low back pain after total hip arthroplasty: a scoping review. BMC Musculoskelet Disord 2022; 23:250. [PMID: 35291992 PMCID: PMC8925238 DOI: 10.1186/s12891-022-05154-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 02/28/2022] [Indexed: 11/30/2022] Open
Abstract
Objective Spinopelvic alignment is increasingly considered as an essential factor for maintaining an energy-efficient posture in individuals with normal or pathological status. Although several previous studies have shown that changes in the sagittal spinopelvic alignment may occur in patients undergoing total hip arthroplasty (THA), no review of this area has been completed so far. Thus, the objective of this scoping review was to summarize the evidence investigating changes in spinopelvic alignment and low back pain (LBP) following THA. Data sources We adhered to the established methodology for scoping reviews. Four electronic databases were systematically searched from inception-December 31, 2021. Study selection We selected prospective or retrospective observational or intervention studies that included patients with THA. Data extraction Data extraction and levels of evidence were independently performed using standardized checklists. Data synthesis A total of 45 papers were included in this scoping review, involving 5185 participants with THA. Pelvic tilt was the most common parameter measured in the eligible studies (n = 26). The results were not consistent across all studies; however, it was demonstrated that the distribution of pelvic tilt following THA had a range of 25° posterior to 20° anterior. Moreover, decreased sacral slope and lower pelvic incidence were associated with increased risk of dislocation in patients with THA. Lumbar spine scoliosis did not change significantly after THA in patients with bilateral hip osteoarthritis (5.50°(1.16°) vs. 3.73°(1.16°); P-value = 0.29). Finally, one study indicated that LBP improvement was not correlated with postoperative changes in spinopelvic alignment parameters. Several methodological issues were addressed in this study, including no sample size calculation and no type-I error adjustment for outcome multiplicity. Conclusions Changes in spinopelvic alignment may occur after THA and may improve with time. Patients with a THA dislocation usually show abnormal spinopelvic alignment compared to patients without a THA dislocation. LBP usually improves markedly over time following THA.

Abstract
Introduction Myofascial pain syndrome (MPS) is one of the most common disorders causing chronic muscle pain. Almost one-third of patients with musculoskeletal complaints meet the MPS criteria. The aim of this study is to evaluate the effectiveness of intramuscular electrical stimulation (IMES) in patients with MPS through a systematic review method. Methods PubMed, Scopus, Embase, ProQuest, PEDro, Web of Science, and CINAHL were systematically searched to find out the eligible articles without language limitations from 1990 to December 30, 2020. All relevant randomized controlled trials that compared the effectiveness of IMES with sham-IMES, dry needling, or exercise therapy in patients with MPS were included. Full texts of the selected studies were critically appraised using Revised Cochrane risk-of-bias tool for randomized trials (RoB2). Results Six studies (out of 397) had met our inclusion criteria (involving 158 patients) and were entered to the systematic review. Outcome measures examined in these studies included pain, range of motion, pressure pain threshold, biochemical factors, disability, and amount of analgesic use. In the most studies, it has been shown that IMES is more effective than the control group in improving some outcome measurements such as pain. Conclusion There is preliminary evidence from a few small trials suggesting the efficacy of IMES for the care of myofascial pain syndrome. The data support the conduct of larger trials investigating the efficacy of IMES. Supplementary Information The online version contains supplementary material available at 10.1186/s12998-021-00396-z.

Abstract
BACKGROUND Lower limb disability is common in chronic stroke patients, and aquatic therapy is one of the modalities used for the rehabilitation of these patients. OBJECTIVES To summarize the evidence of the effects of aquatic therapy on lower limb disability compared to land-based exercises in post-stroke patients. METHODS MEDLINE, PsycInfo, CENTRAL, SPORTDiscus, PEDro, PsycBITE, and OT Seeker were searched from inception to January 2019. The search included only randomized clinical trials. Two reviewers independently examined the full text and conducted study selection, data extraction, and quality assessment. Data synthesis was applied to summarize information from the included studies. The quantitative analysis incorporated fixed-effect models. RESULTS Of the 150 studies identified in the initial search, 17 trials (629 participants) satisfied the eligibility criteria. Aquatic therapy improved balance based on the Berg Balance Scale (BBS) (standardized mean difference [SMD], 0.72; 95% confidence interval [CI], 0.50-0.94; I2 = 67%) compared with land-based exercises (control). Also, aquatic therapy had a small positive effect on walking speed (SMD, -0.45; 95% CI {-0.71 - (-0.19)}; I2 = 57%), based on the results of the 10-m walking test, compared to controls. Aquatic therapy had a small positive effect on mobility (based on Timed Up and Go), (SMD, -0.43; 95% CI {-0.7-(- 0.17)}; I2 = 71%) compared to land-based exercise (control). CONCLUSIONS Aquatic therapy had a more positive effect on walking speed, balance, and mobility than land-based exercises. Further research is needed to confirm the clinical utility of aquatic therapy for patients following stroke in the long term.

Abstract
OBJECTIVE Dry needling is a treatment technique used by clinicians to relieve symptoms in patients with tension-type headache (TTH), cervicogenic headache (CGH), or migraine. This systematic review's main objective was to assess the effectiveness of dry needling on headache pain intensity and related disability in patients with TTH, CGH, or migraine. METHODS Medline/PubMed, Scopus, Embase, PEDro, Web of Science, Ovid, Allied and Complementary Medicine Database/EBSCO, Cochrane Central Register of Controlled Clinical Trials, Google Scholar, and trial registries were searched until April 1, 2020, along with reference lists of eligible studies and related reviews. Randomized clinical trials or observational studies that compared the effectiveness of dry needling with any other interventions were eligible for inclusion. Three reviewers independently selected studies, extracted data, and assessed risk of bias. Random-effects meta-analyses were performed to produce pooled-effect estimates (Morris dppc2) and their respective CIs. RESULTS Of 2715 identified studies, 11 randomized clinical trials were eligible for qualitative synthesis and 9 for meta-analysis. Only 4 trials were of high quality. Very low-quality evidence suggested that dry needling is not statistically better than other interventions for improving headache pain intensity in the short term in patients with TTH (SMD -1.27, 95% CI = -3.56 to 1.03, n = 230), CGH (SMD -0.41, 95% CI = -4.69 to 3.87, n = 104), or mixed headache (TTH and migraine; SMD 0.03; 95% CI = -0.42 to 0.48, n = 90). Dry needling provided significantly greater improvement in related disability in the short term in patients with TTH (SMD -2.28, 95% CI = -2.66 to -1.91, n = 160) and CGH (SMD -0.72, 95% CI = -1.09 to -0.34, n = 144). The synthesis of results showed that dry needling could significantly improve headache frequency, health-related quality of life, trigger point tenderness, and cervical range of motion in TTH and CGH. CONCLUSIONS Dry needling produces similar effects to other interventions for short-term headache pain relief, whereas dry needling seems to be better than other therapies for improvement in related disability in the short term. IMPACT Although further high-methodological quality studies are warranted to provide a more robust conclusion, our systematic review suggested that for every 1 or 2 patients with TTH treated by dry needling, 1 patient will likely show decreased headache intensity (number needed to treat [NNT] = 2; large effect) and improved related disability (NNT = 1; very large effect). In CGH, for every 3 or 4 patients treated by dry needling, 1 patient will likely exhibit decreased headache intensity (NNT = 4; small effect) and improved related disability (NNT = 3; medium effect).

Abstract
Spasticity is one of the main complications of a stroke. This double-blind, randomized controlled trial aimed to compare the result of three sessions of dry needling (DN) versus sham DN on the affected upper limbs in post-stroke survivors. We recruited 24 patients (age 57.0 ±
9.6 years; male 71%). Patients were randomly allocated to two groups: a DN group and a sham DN group. The primary outcome measures were the Modified Modified Ashworth Scale (MMAS) and the Box and Block Test (BBT). Secondary outcome measures included active and passive wrist range of motion
(AROM and PROM). All assessments were measured at baseline, immediately after the last session of the intervention, and one month later. Patients in the DN group had improved upper limb spasticity and passive wrist range of motion compared to control group (P < 0.05). There were
no between-group differences in other outcome measures (P > 0.05). Dry needling is a useful method for improving muscle spasticity in the upper limbs of patients with stroke.

Abstract
Myofascial pain syndrome (MPS), trigger points (TrPs), and dry needling (DN) continue to be of interest to researchers and clinicians worldwide. In this quarterly overview, we included studies from 19 countries, including Pakistan, Iran, Spain, Israel, the US, Australia, Turkey, the UK, China, Italy, Germany, Brazil, Denmark, Canada, Saudi Arabia, Egypt, India, New Zealand, and Thailand. As encouraging as it may be that myofascial pain is being considered worldwide, it is frustrating how many studies do not include a proper control group making them not very useful. It is not clear why researchers would go through the trouble of setting up a study, which requires many hours of work and dedication, and not produce a meaningful paper for clinicians and researchers alike. Fortunately, several papers are high quality studies. This overview covers 39 basic research studies, systematic reviews and meta-analyses, clinical studies, and a few case reports.

Abstract
CONTEXT Hamstring muscle tightness is one of the most common problems in athletic and healthy people. Dry needling (DN) was found to be an effective approach for improving muscle flexibility, but there is no study to compare this approach with static stretching (SS) as a common technique for the increase of muscle length. OBJECTIVE To compare the immediate effects of DN and SS on hamstring flexibility in healthy subjects with hamstring tightness. STUDY DESIGN A single-blind randomized controlled trial. SETTING A musculoskeletal physiotherapy clinic at Tehran University of Medical Sciences. SUBJECTS Forty healthy subjects (female: 32, age range: 18-40 y) with hamstring tightness were randomly assigned into 2 groups of DN and SS. INTERVENTION The DN group received a single session of DN on 3 points of the hamstring muscles, each for 1 minute. The SS group received a single session of SS of the hamstrings, consisting of 3 sets of 30-second SS with a 10-second rest between sets in the active knee extension test (AKET) position. MAIN OUTCOME MEASURES The AKET, muscle compliance, passive peak torque, and stretch tolerance were measured at the baseline, immediately, and 15 minutes after the interventions. RESULTS Improvements in all outcomes was better for the DN group than for the SS group. DN increased muscle compliance significantly 15 minutes after the intervention, but it did not improve in the SS group. CONCLUSION DN is effective in improving hamstring flexibility compared with SS. One session of DN can be an effective treatment for hamstring tightness and increase hamstring flexibility. The improvements suggest that DN is a novel treatment for hamstring flexibility.

Abstract
We are sad to report that following this issue, Dr. Li-Wei Chou will no longer be able to contribute to this quarterly literature overview. Unfortunately, his work responsibilities have increased to such an extent that they need to take priority. On behalf of the team, we would like to thank Dr. Chou for his thoughtful and balanced reviews during the past few years. Not only were we able to include an occasional Chinese-language study, he also was able to assist us in interpreting more complex medical studies. Li-Wei, we wish you all the best professionally and personally, and of course, we cannot wait until our paths will cross again sometime in the future! You may have noted that this overview article was missing from the January 2020 issue of the journal due to an administrative mix up. With the current issue we aimed to catch up and therefore, you will find a greater number of reviewed articles than usual. It becomes increasingly challenging to cover the wide range of the published myofascial pain and trigger point (TrP) literature just due to its volume. In this edition, we included 10 basic research articles, 4 reviews, 14 articles on dry needling (DN), acupuncture, and injections, 3 on manual therapies, and 4 on other clinical approaches.

Impact of physical therapists' instructions on function and the perception of post-dry needling soreness in mechanical cervical pain; a randomized clinical trial. J Bodyw Mov Ther 2020; 24:118-123. [PMID: 33218498 DOI: 10.1016/j.jbmt.2020.06.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2019] [Revised: 03/10/2020] [Accepted: 06/07/2020] [Indexed: 01/01/2023]
Abstract
BACKGROUND To investigate the impact of physical therapists' instructions on the perception of post dry needling (DN) soreness and function in patients with mechanical neck pain. METHODS Seventy-five patients with neck pain were randomly assigned to three groups: "positive" group (n = 25) received positive verbal input; "negative" group (n = 25) received negative verbal input, and control group (n = 25) did not receive any input about post-needling soreness. All three groups received DN of a trigger point in the upper trapezius muscle. The subjective pain experience, pressure pain threshold (PPT), and neck disability Index (NDI) were assessed before and after DN. RESULTS Patients in all groups showed improvement in pain, PPT and NDI. There were no significant differences in pain (P = 0.41) and PPT (P = 0.68) in the positive and negative groups compared with the control group. Significant difference in function was seen with the NDI after DN of patients in the positive and negative groups compared with the control group (P = 0.011, standard error: 1.08-1.5). CONCLUSION Considering that the power of our study may be too low to draw more definitive conclusions, DN appears to be an effective technique to improve pain and mechanical hyperalgesia. The experience of post-needling soreness does not appear to influence the outcome of DN on pain, PPT, and NDI. Post-needling soreness does not seem to be a limiting factor in achieving acceptable outcomes, especially when clinicians offer DN within a therapeutic emphasizing a positive patient response. This study questions whether any treatments need to be offered to patients receiving DN.

Abstract
BACKGROUND Spasticity is one of the main complications in poststroke survivors leading to difficulties in walking and standing resulting in high levels of disability. OBJECTIVE The aim of the study was to investigate the effects of deep dry needling on lower limb dysfunction in poststroke spastic patients. METHODS A randomized clinical trial conducted in poststroke survivors who were assigned to one of 2 groups: Deep dry needling (intervention group) and sham dry needling (control group). The primary outcome measures were Modified Modified Ashworth Scale (MMAS) and functional tests (timed up and go test, 10-meter walk test). Secondary outcome measures were active ankle dorsiflexion range of motion (AROM), passive ankle dorsiflexion range of motion (PROM), single leg stance test, and Barthel index. All measurements were assessed at baseline (T0), immediately after the third session 1 week later (T1), and 1 month after the end of the intervention (T2). RESULTS We recruited 24 patients (71% male; mean age 57 ± 10 years; 26.4 ± 1.8 kg•m-2; time since event: 25.2 ± 12.5 months). There were significant improvements in MMAS, timed up and go test, 10-meter walk test, Barthel scale, and PROM (P < .05) in the intervention group compared to controls across the time-points. There were no significant improvements in AROM assessments (P > .05). CONCLUSIONS Deep dry needling decreases muscle spasticity and improves lower limb function and gait speed in poststroke survivors.

Abstract
CONTEXT There are numerous studies on the benefits of dry needling (DN) for pain relief. No studies exist examining the effects of DN on hamstring flexibility. OBJECTIVE To determine the immediate effects of DN on hamstring flexibility in healthy subjects with shortened hamstrings. DESIGN A single-blinded, pretest-posttest clinical pilot study. SETTING A university physiotherapy clinic. SUBJECTS A total of 15 healthy subjects (female = 11; age = 23.26 [4.3] y) with shortened hamstrings participated in this study. INTERVENTION Subjects received a single session of DN. Three locations on the hamstring muscle group were needled, each for 1 minute. MAIN OUTCOME MEASURES The active knee extension test, muscle compliance, passive peak torque, and stretch tolerance were measured at baseline, immediately, and 15 minutes after DN. RESULTS There were statistically significant improvements in all outcome measures immediately after DN and at the 15-minute follow-up. The effect sizes for all outcome measures were large (Cohen's d ≥ 0.8). No serious adverse events were observed with DN. CONCLUSIONS This is the first study that demonstrates the beneficial effects of DN on hamstring flexibility, muscle compliance, and stretch tolerance without added stretching. The beneficial effects of DN should encourage clinicians to use DN as a novel strategy for increasing muscle flexibility.

Effectiveness of dry needling for improving pain and disability in adults with tension-type, cervicogenic, or migraine headaches: protocol for a systematic review. Chiropr Man Therap 2019; 27:43. [PMID: 31572570 PMCID: PMC6761714 DOI: 10.1186/s12998-019-0266-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Accepted: 07/02/2019] [Indexed: 02/08/2023] Open
Abstract
Background Headache is the most common neurological symptoms worldwide, as over 90% of people have noted at least one headache during their lifetime. Tension-type headaches, cervicogenic headaches, and migraines are common types of headache which can have a significant impact on social, physical, and occupational functioning. Therapeutic management of headaches mainly includes physical therapy and pharmacological interventions. Dry needling is a relatively new therapeutic approach that uses a thin filiform needle without injectate to penetrate the skin and stimulate underlying tissues for the management of neuromusculoskeletal pain and movement impairments. The main objective of this systematic review and meta-analysis is to evaluate the effectiveness of dry needling in comparison to other interventions on pain and disability in patients with tension-type headache, cervicogenic headache, and migraine. Methods/design We will focus on clinical trials with concurrent control group(s) and comparative observational studies assessing the effect of dry needling in patients with tension-type headache, cervicogenic headache, and migraine. Electronic databases from relevant fields of research (PubMed/ Medline, Scopus, Embase®, PEDro, Web of Science, Ovid, AMED, CENTRAL, and Google Scholar) will be searched from inception to June 2019 using defined search terms. No restrictions for language of publication or geographic location will be applied. Moreover, grey literature, citation tracking, and reference lists scanning of the selected studies will be searched manually. Primary outcomes of this study are pain intensity and disability, and secondary outcomes are cervical spine ROM, frequency of headaches, health-related quality of life, and TrPs tenderness. Studies will be selected by three independent reviewers based on prespecified eligibility criteria. Three reviewers will independently extract data in each eligible study using a pre-piloted Microsoft Excel data extraction form. The assessment of risk of bias will be implemented using the Cochrane Back and Neck Review Group 13-item criteria and NOS. Direct meta-analysis will be performed using a fixed or random effects model to estimate effect size such as standardized mean difference (Morris’s dppc) and 95% confidence intervals. Statistical heterogeneity will also be evaluated using the I2 statistic and the χ2 test. All meta-analyses will be performed using Stata V.11 and V.14 softwares. The overall quality of the evidence for the primary outcomes will be assessed using GRADE. Discussion All analyses in this study will be based on the previous published papers. Therefore, ethical approval and patient consent are not required. The findings of this study will provide important information on the value of dry needling for the management of tension-type headache, cervicogenic headache, and migraine. Trial registration PROSPERO registration number: CRD42019124125.

Abstract
Low back pain is a major health issue affecting the lumbopelvic muscles. Morphological changes in hip muscles, such as alterations in the muscle cross-sectional area and muscle volume, may occur in patients with low back pain. This systematic review was conducted to investigate whether patients with low back pain have macroscopic changes in their hip muscle morphology compared with asymptomatic, healthy individuals, based on current evidence. The electronic databases of PubMed/Medline, Ovid, Scopus, Embase® , and Google Scholar were searched from the inception to August 31, 2018. We only included full texts of original studies regarding macroscopic morphological alterations, including atrophy and fat infiltration, in hip muscles of patients with low back pain compared with asymptomatic controls. The quality of the included studies was determined using an assessment tool based on the Newcastle-Ottawa Scale. The scale was modified for the purposes of this study. Sixteen comparative observational studies were found eligible to be included in this review. Eleven were classified as high quality and four as moderate quality. The morphological changes in the psoas major, gluteus maximus, gluteus medius, gluteus minimus, and piriformis muscles were assessed in the primary studies. All selected studies were considered B level of evidence studies. The strength of conclusions for the psoas major, gluteal, and piriformis muscles was moderate. The results revealed that there is substantial controversy about the morphological changes in hip muscles in patients with low back pain; however, the majority of high-quality studies concluded that atrophy of hip muscles is evident in patients with low back pain. The psoas major muscle was the most commonly investigated hip muscle for morphological changes. Major methodological limitations of the included studies were identified and discussed. The present systematic review does not include a formal meta-analysis because of very significant differences in the primary studies in terms of study populations and methodologies. Finally, in clinical practice, it is recommended that physical therapists develop exercise programs to improve hip muscle function in patients with low back pain.

Abstract
This edition of the overview of current myofascial pain literature features several interesting and important publications. From Australia, Braithwaite and colleagues completed an outstanding systematic review of blinding procedures used in dry needling (DN) studies. Other papers tackled the interrater reliability of the identification of trigger points (TrP), the presence of muscle hardness related to latent TrPs, pelvic floor examination techniques, and the links between TrPs, headaches and shoulder pain. Israeli researchers developed a theoretical model challenging the contributions of the Cinderella Hypothesis to the development of TrPs. As in almost all issues, we included many DN, injection and acupuncture studies, which continue to be the focus of researchers all over the world.

Abstract
Objectives: Prudent dry needling techniques are commonly practiced with the intent to avoid large neurovascular structures, thereby minimizing potential excessive bleeding and neural injury. Patient position is one factor thought to affect the size of the safe zone during dry needling of some muscles. This study aimed to compare the size of the needle safe zone of the iliacus muscle during two different patient positions using ultrasound imaging. Methods: The distance from the anterior inferior iliac spine (AIIS) to the posterior pole of the femoral nerve was measured in 25 healthy participants (11 male, 14 female, mean age = 40) in both supine and sidelying positions using a Chison Eco1 musculoskeletal ultrasound unit. The average distance was calculated for each position and a two-tailed, paired t-test (α < 0.05) was used to examine the difference between positions. Results: The mean distance from the AIIS to the posterior pole of the femoral nerve was statistically greater with participants in the sidelying position (mean[SD] = 35.7 [6.2] mm) than in the supine position (mean[SD] = 32.1 [7.3] mm, p < .001). Discussion: Although more study is needed, these results suggest that patient positioning is one of several potential variables that should be considered in the optimization of patient safety/relative risk when performing trigger point dry needling. Level of Evidence: Level 4 (Pre-Post Test).

Abstract
Objective There is no consensus on the essential diagnostic criteria for diagnosing a trigger point (TrP). In fact, a variety of diagnostic criteria are currently being used. Our aim was to conduct a Delphi panel to achieve an international consensus on the cluster of criteria needed for the TrP diagnosis to reach a consensus on the definition of active and latent TrPs and to clarify different clinical considerations about TrPs. Methods Following international guidelines, an international three-round Delphi survey was conducted. Questions were created based on a systematic literature search of the diagnostic criteria for TrPs. Results Sixty experts from 12 countries completed all rounds of the survey. A cluster of three diagnostic criteria was proposed as essential for the TrP diagnosis: a taut band, a hypersensitive spot, and referred pain. Eighty percent of the experts agreed that the referred pain elicited by a TrP can include different sensory sensations and not just pain, that is, pain spreading to a distant area, deep pain, dull ache, tingling, or burning pain. Eighty-four percent of the international experts consistently answered that the main clinical differences between active and latent TrPs are the reproduction of any of the symptoms experienced by a patient and the recognition of pain. No specific location of the pain referral area and TrP location should be expected. Conclusions This Delphi panel has produced an expert-based standardized definition of a TrP with a discussion of the clinical components, including the definition of referred pain and the difference between active and latent TrPs, thereby providing a foundation for future research in MPS.

Abstract
This is the first issue of this review column since the passing of Dr. Leon Chaitow. We would like to take a brief moment to acknowledge how much his mentorship, friendship, and confidence have meant to us. Leon was a force in osteopathic and naturopathic medicine and his influence reaches to all corners of the musculoskeletal realm crossing over many disciplines through his lectures, workshops, and of course, his many books, editorials, and articles. In the foreword to one of his books, Jan Dommerholt wrote that "Leon Chaitow […] continued the work of Travell and Simons, but also of many others, whose contributions he has skillfully woven into an intricate tapestry of clinical pearls, practical tips, and solid evidence-informed research." Dr. Chaitow was a synthesizer, who always considered what different clinicians and researchers could possibly contribute to a better understanding of pain and dysfunction and provide real solutions to real problems. Even when he would not necessarily agree with all suggested remedies, he maintained an open mind and was able to take a step back and consider the bigger picture. For example, Leon was not a big fan of dry needling, yet, he valued the importance of this approach and encouraged the inclusion of dry needling papers in this review article and in his journal. The Journal of Bodywork and Movement Therapies became his baby and, considering the growth of the journal, there is no question that Leon's intense focus and efforts are appreciated by many around the globe. We wish to extend our condolences to Leon's wife Alkmini and daughter Sasha. He will surely be missed, but we can find peace in knowing that his legacy will stay with us forever. In this issue, we have included several basic myofascial pain research articles. As usual, dry needling (DN) studies and case reports are the most commonly referenced papers, but we also included neuroscience and electromyography studies, sleep studies, interrater reliability studies, and case reports of adverse events.

Abstract
Twenty-four basic and clinical studies and case reports are included in this quarterly review of the myofascial pain literature. The majority of publications focus on invasive techniques, especially dry needling. We hope, that this not suggest that clinicians and researchers are slowly moving away from manual trigger point (TrP) approaches. While some physiotherapists have bought into the notion that hands-on approaches are a thing of the past, since "pain is in the brain" and "the issues are not in the tissues," there is also a body of research that aims to combine so-called top-down and bottom-up therapies. Combining manual therapy and dry needling with pain neuroscience education is likely the preferred method using a multimodal approach (Puentedura and Flynn, 2016; Lluch Girbes et al., 2015).

Abstract
The majority of papers included in the quarterly review discuss various aspects of dry needling (DN), which continues to be of interest to researchers and clinicians. A study by Liu et al. is the first paper to examine the effects of DN of acetylcholine, esterase and receptors. The study provides support for the integrated trigger point hypothesis and for DN. A paper by Hightower and colleagues found an intriguing link between low magnesium levels in the drink water supply, vitamin D, and myofascial pain, cancer, tendon ruptures, and colon polyps. Contributions originated in the Brazil, China, Germany, Iran, India, Poland, South Korea, Spain, Taiwan, Turkey, and the US.

Background: Disk herniation is the most common cause of radiating low back pain (LBP) in subjects under 60 years of age. The present study aims to compare the effect of dry needling (DN) and a standard conservative approach on the pain and function in subjects with discogenic radiating LBP. Materials and Methods: Fifty-eight subjects with discogenic radicular LBP were screened and randomized into control (Standard physical therapy, n = 29) and experimental group (Standard physical therapy and DN, n = 29). Radiating pain intensity and disability were measured using visual analog scale (VAS) and Oswestry Disability indices at baseline, at the end of treatment and 2 months after the last intervention session. The changes in pain intensity and disability were studied using a 3 × 2 repeated measures analysis of variance considering time as the within-subject factor and group as the between-subject. Results: Pain intensity and disability scores decreased significantly in both experimental and control groups (experimental group: VAS = 37.24, Oswestry Disability Index [ODI] =28.48, control group: VAS = 45.5, ODI = 32.96), following the intervention. The change continued during the follow-up period (P < 0.001 for all comparisons). Pain and disability improvement, however, were more significant in experimental group, both in post intervention (experimental group: VAS = 25.17, ODI = 22.17, control group: VAS = 42.4, ODI = 30.27) (P = 0.05 and P = 0.03, respectively) and follow-up measures (P = 0.006 and P = 0.002, respectively). Conclusion: Both intervention strategies seem to significantly improve pain and disability immediately following intervention, where the improvement continued during 2 months after the last active intervention. Therefore, supplementary DN application may enhance the effect of the standard intervention considerably.

Abstract
This edition of the overview of the current myofascial pain literature includes 24 studies, case reports and systematic and narrative reviews. Surprisingly, five of the 24 papers were difficult to read and interpret mostly because of a poor mastery of the English language. It is somewhat surprising that journal editors and reviewers would accept papers that are needlessly difficult to read and not direct the authors to language services or others who could improve the quality of the writings. Of course, it is exciting that researchers and clinicians from all over the world continue to focus on myofascial pain and attempt to shed new light on the complexity of the problem to improve the clinical decision-making process and eventually clinical approaches and outcomes. There were no new papers on manual therapies, but many focused on dry needling.

Prevalence of Myofascial Pain Syndrome in Chronic Non-Specific Neck Pain: A Population-Based Cross-Sectional Descriptive Study. PAIN MEDICINE 2016; 17:2369-2377.

Abstract
BACKGROUND Chronic non-specific neck pain is a frequent complaint. It is a recognized medical and socioeconomic problem and a frequent cause of job absenteeism. In recent years, case reports about myofascial pain syndrome (MPS) are emerging among patients suffering from pain. MPS is a regional pain syndrome characterized by myofascial trigger points (MTrP) in palpable taut bands of skeletal muscle that refer pain to a distance, and that can cause distant motor and autonomic effects. OBJECTIVE To assess the prevalence of active and latent MTrPs in subjects suffering from chronic non-specific neck pain. DESIGN A population-based cross-sectional descriptive study was carried out from January 2012 to December 2014. SETTING Three primary healthcare centers in Alcalá de Henares, Madrid (Spain). SUBJECTS Two hundred and twenty-four participants diagnosed by their family doctor with chronic non-specific neck pain. METHODS Participants were examined by a physical therapist to determine the presence of MPS. Pain descriptions from the subjects and pain body diagrams guided the physical examination. The subjects were not given any information concerning MPS or other muscle pain syndromes. RESULTS All participants presented with MPS. MTrPs of the trapezius muscles were the most prevalent, in 93.75% of the participants. The most prevalent active MTrPs were located right (82.1%) and left (79%) in the nearly-horizontal fibers of the upper trapezius muscle. Furthermore, active MTrPs in the levator scapulae, multifidi, and splenius cervicis muscles reached a prevalence of 82.14%, 77.68%, and 62.5%, respectively. CONCLUSIONS MPS is a common source of pain in subjects presenting chronic non-specific neck pain.

Abstract
A nearly forgotten reaction discovered more than 60 years ago-the cycloaddition of a cyclic alkyne and an organic azide, leading to an aromatic triazole-enjoys a remarkable popularity. Originally discovered out of pure chemical curiosity, and dusted off early this century as an efficient and clean bioconjugation tool, the usefulness of cyclooctyne-azide cycloaddition is now adopted in a wide range of fields of chemical science and beyond. Its ease of operation, broad solvent compatibility, 100 % atom efficiency, and the high stability of the resulting triazole product, just to name a few aspects, have catapulted this so-called strain-promoted azide-alkyne cycloaddition (SPAAC) right into the top-shelf of the toolbox of chemical biologists, material scientists, biotechnologists, medicinal chemists, and more. In this chapter, a brief historic overview of cycloalkynes is provided first, along with the main synthetic strategies to prepare cycloalkynes and their chemical reactivities. Core aspects of the strain-promoted reaction of cycloalkynes with azides are covered, as well as tools to achieve further reaction acceleration by means of modulation of cycloalkyne structure, nature of azide, and choice of solvent.

Abstract
The worldwide interest in myofascial pain syndrome (MPS) and trigger points (TrPs) is reflected in the increasing number of publications. In this overview of the literature, we included 26 studies, case reports and review articles by authors from 18 different countries. Several research groups are exploring the characteristic of TrPs such as Chen and colleagues, who continued their work on the quantification of the taut bands. Meng and colleagues studied the relationships between TrPs and central sensitization, while Yu and colleagues examined the electrophysiological characteristics that occur as a result of active TrPs. Several researchers used objective measurements to determine clinical outcomes, such as Koppenhaver and colleagues who measured objective changes in the function and nociceptive sensitivity of lumbar multifidus muscle subjects with low back pain. Turo and colleagues quantified muscle tissue changes after dry needling in chronic myofascial pain using elastography. Multiple studies explored various treatment options for TrPs, such as dry needling, injections with lidocaine or granisetron, traditional Thai massage, self-myofascial release, kinesiotaping, and monochromatic infrared photo energy, among others.

Abstract
Thoracic spine pain is as disabling as neck and low back pain without receiving the same level of attention in the scientific literature. Among the different structures that can refer pain to the thoracic spine, muscles often play a relevant role. Trigger points (TrPs) from neck, shoulder and spinal muscles can induce pain in the region of the thoracic spine. There is a lack of evidence reporting the presence of TrPs in the region of the thoracic spine, but clinical evidence suggests that TrPs can be a potential source of thoracic spine pain. The current paper discusses the role of TrPs in the thoracic spine and dry needling (DN) for the management of TrPs in the thoracic multifidi and longissimus thoracis. This paper also includes a brief discussion of the application of DN in other tissues such as tendons, ligaments and scars.
