RESUMO

OBJECTIVE: Aim: To compare the effectiveness of end-range mobilization and therapeutic exercises, used in combination with ischemic compression, on disability and pain indicators among patients with adhesive capsulitis of the shoulder joint and thoracic myofascial pain syndrome. PATIENTS AND METHODS: Materials and Methods: The study involved 68 patients. Goniometry of the shoulder joint, assessment of pain in myofascial trigger points, and the Shoulder Pain and Disability Index questionnaire were used before and after physical therapy. The duration of physical therapy comprised 3 weeks. Physical therapy of the first group of patients consisted of end-range mobilization and ischemic compression. Patients of the second group performed therapeutic exercises and ischemic compression. RESULTS: Results: Both groups demonstrated positive dynamics of shoulder joint mobility, Shoulder Pain and Disability Index and pain in trigger points. However, the final results of the studied indicators were better in the first group of patients. CONCLUSION: Conclusions: Physical therapy based on the combination of end-range mobilization and ischemic compression had a more positive impact on disability and pain indicators for adhesive capsulitis of the shoulder joint and myofascial pain syndrome as compared to the combination of therapeutic exercises and ischemic compression.

RESUMO

Myofascial pain syndrome (MPS) is the most common in the musculoskeletal disease. Dry needling techniques and ischemic compression are the most common applications. We aimed to compare the efficacy of dry needling and ischemic compression methods on pain, cervical range of motion and disability in myofascial pain syndrome. This is a randomized, controlled study. 98 patients with MPS were randomly assigned into three groups. Group1 received dry needling (n=33), group 2 (n=33) received ischemic compression and group 3 (n=32) received combined with dry needling and ischemic compression inventions. Additionally, all patients were given neck exercise programs including isotonic, isometric, and stretching. The severity of the pain was measured by visual analog scale (VAS). The pressure pain threshold (PPT) and cervical range of motion (ROM) were also recorded. Disability was assessed by the Neck Pain Disability Scale. All assessments were performed before the treatment and one month and three months after the treatment. There were statistically significant improvements in VAS, PPT, cervical ROM, and disability scores after one and three months in all groups compared to pre-treatment results (p<0.05). After three months of follow-up, statistically significant differences were observed in all parameters between the groups (p<0.05) except cervical ROM (p>0.05). Myofascial pain syndrome in patients with ischemic compression and dry needling effective treatment methods are shown separately in our study to be more effective when used together.

RESUMO

The antinociceptive effect of BoNT-A have been well documented in animal studies; however, results of few but well-designed randomized placebo-controlled clinical trials about BoNT-A efficacy in masticatory myofascial pain (MFP) are inconsistent. Therefore, the present randomized, double-blind, placebo-controlled clinical trial evaluated the efficacy of BoNT-A in patients with refractory MFP. Twenty-eight patients with pain reduction of less than 30% despite conservative treatment and with an average pain intensity of > 50 mm on the visual analogue scale (VAS) participated. Patients were randomly assigned to receive a total of 80 U of BoNT-A or saline solution (SS) injected into the masseter and anterior temporalis muscles. Pain intensity (VAS), quantitative sensory testing (QST), conditioned pain modulation (CPM), and psychosocial status were examined. Follow-up was performed at 1 and 6 months. For repeated-measure comparisons between evaluation times, Friedman test with Bonferroni correction was used for pain and somatosensory variables and the Wilcoxon test for the psychosocial variables. The Mann-Whitney test was used for all comparisons between groups. The BoNT-A group had a significant decrease in pain intensity at follow-ups compared with the SS group (p < 0.001). QST assessment revealed higher pressure pain threshold values in the masseter muscle for BoNT-A group compared to SS (p < 0.03) at all follow-ups. No differences were found for mechanical pain threshold and wind-up ratio values (p > 0.05) in the entire study. The BoNT-A group presented the most efficient CPM effect (p < 0.03) only at the 1 month follow-up in the masseter muscle. There was a significant time effect for BoNT-A in all psychosocial variables (p < 0.05) and a drug effect in the Central Sensitization Inventory (p < 0.01), Pittsburgh Sleep Quality Index (p < 0.004), and Healthy Survey 36 (p < 0.05) at 6 months follow-up. The study demonstrates that a single injection-session of BoNT-A has positive effects on the hall pain spectrum of patients with refractory masticatory myofascial pain.

RESUMO

Needle electromyogram (EMG) research has suggested that endplate noise (EPN) is a characteristic of myofascial trigger points (MTrPs). Although several studies have observed MTrPs through ultrasonography, whether they are hyperechoic or hypoechoic in ultrasound images is still controversial. Therefore, this study determined the echogenicity of MTrP ultrasonography. In stage 1, the MTrP of rat masseter muscle was identified through palpation and marked. Needle EMG was performed to detect the presence of EPN. When EPN was detected, ultrasound scans and indwelling needles were used to identify the nodule with a different grayscale relative to that of its surrounding tissue, and the echogenicity of the identified MTrP was determined. In stage 2, these steps were reversed. An ultrasound scan was performed to detect the nodule at the marked site, and an EMG needle was inserted into the nodule to detect EPN. There were 178 recordings in each stage, obtained from 45 rats. The stage 1 results indicate that the MTrPs in ultrasound images were hypoechoic with a 100% sensitivity of assessment. In stage 2, the accuracy and precision of MTrP detection through ultrasonography were 89.9% and 89.2%, respectively. The results indicate that ultrasonography produces highly accurate and precise MTrP detection results.

RESUMO

Complications associated with pelvic organ prolapse (POP) surgery using a synthetic non-absorbable mesh are uncommon (<5%) but may be severe and may hugely diminish the quality of life of some women. In drawing up these multidisciplinary clinical practice recommendations, the French National Authority for Health (Haute Autorité de santé, HAS) conducted an exhaustive review of the literature concerning the diagnosis, prevention, and management of complications associated with POP surgery using a synthetic mesh. Each recommendation for practice was allocated a grade (A,B or C; or expert opinion (EO)), which depends on the level of evidence (clinical practice guidelines). PREOPERATIVE PATIENTS' INFORMATION: Each patient must be informed concerning the risks associated with POP surgery (EO). HEMORRHAGE, HEMATOMA: Vaginal infiltration using a vasoconstrictive solution is not recommended during POP surgery by the vaginal route (grade C). The placement of vaginal packing is not recommended following POP surgery by the vaginal route (grade C). During laparoscopic sacral colpopexy, when the promontory seems highly dangerous or when severe adhesions prevent access to the anterior vertebral ligament, alternative surgical techniques should be discussed per operatively, including colpopexy by lateral mesh laparoscopic suspension, uterosacral ligament suspension, open abdominal mesh surgery, or surgery by the vaginal route (EO). BLADDER INJURY: When a bladder injury is diagnosed, bladder repair by suturing is recommended, using a slow resorption suture thread, plus monitoring of the permeability of the ureters (before and after bladder repair) when the injury is located at the level of the trigone (EO). When a bladder injury is diagnosed, after bladder repair, a prosthetic mesh (polypropylene or polyester material) can be placed between the repaired bladder and the vagina, if the quality of the suturing is good. The recommended duration of bladder catheterization following bladder repair in this context of POP mesh surgery is from 5 to 10 days (EO). URETER INJURY: After ureteral repair, it is possible to continue sacral colpopexy and place the mesh if it is located away from the ureteral repair (EO). RECTAL INJURY: Regardless of the approach, when a rectal injury occurs, a posterior mesh should not be placed between the rectum and the vagina wall (EO). Concerning the anterior mesh, it is recommended to use a macroporous monofilament polypropylene mesh (EO). A polyester mesh is not recommended in this situation (EO). VAGINAL WALL INJURY: After vaginal wall repair, an anterior or a posterior microporous polypropylene mesh can be placed, if the quality of the repair is found to be satisfactory (EO). A polyester mesh should not be used after vaginal wall repair (EO). MESH INFECTION (ABSCESS, CELLULITIS, SPONDYLODISCITIS): Regardless of the surgical approach, intravenous antibiotic prophylaxis is recommended (aminopenicillin + beta-lactamase inhibitor: 30 min before skin incision +/- repeated after 2 h if surgery lasts longer) (EO). When spondylodiscitis is diagnosed following sacral colpopexy, treatment should be discussed by a multidisciplinary group, including especially spine specialists (rheumatologists, orthopedists, neurosurgeons) and infectious disease specialists (EO). When a pelvic abscess occurs following synthetic mesh sacral colpopexy, it is recommended to carry out complete mesh removal as soon as possible, combined with collection of intraoperative bacteriological samples, drainage of the collection and targeted antibiotic therapy (EO). Non-surgical conservative management with antibiotic therapy may be an option (EO) in certain conditions (absence of signs of sepsis, macroporous monofilament polypropylene type 1 mesh, prior microbiological documentation and multidisciplinary consultation for the choice of type and duration of antibiotic therapy), associated with close monitoring of the patient. BOWEL OCCLUSION RELATED TO NON-CLOSURE OF THE PERITONEUM: Peritoneal closure is recommended after placement of a synthetic mesh by the abdominal approach (EO). URINARY RETENTION: Preoperative urodynamics is recommended in women presenting with urinary symptoms (bladder outlet obstruction symptoms, overactive bladder syndrome or incontinence) (EO). It is recommended to remove the bladder catheter at the end of the procedure or within 48 h after POP surgery (grade B). Bladder emptying and post-void residual should be checked following POP surgery, before discharge (EO). When postoperative urine retention occurs after POP surgery, it is recommended to carry out indwelling catheterization and to prefer intermittent self-catheterization (EO). POSTOPERATIVE PAIN: Before POP surgery, the patient should be asked about risk factors for prolonged and chronic postoperative pain (pain sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Concerning the prevention of postoperative pain, it is recommended to carry out a pre-, per- and postoperative multimodal pain treatment (grade B). The use of ketamine intraoperatively is recommended for the prevention of chronic postoperative pelvic pain, especially for patients with risk factors (preoperative painful sensitization, allodynia, chronic pelvic or non-pelvic pain) (EO). Postoperative prescription of opioids should be limited in quantity and duration (grade C). When acute neuropathic pain (sciatalgia or pudendal neuralgia) resistant to level I and II analgesics occurs following sacrospinous fixation, a reintervention is recommended for suspension suture removal (EO). When chronic postoperative pain occurs after POP surgery, it is recommended to systematically seek arguments in favor of neuropathic pain with the DN4 questionnaire (EO). When chronic postoperative pelvic pain occurs after POP surgery, central sensitization should be identified since it requires a consultation in a chronic pain department (EO). Concerning myofascial pain syndrome (clinical pain condition associated with increased muscle tension caused by myofascial trigger points), when chronic postoperative pain occurs after POP surgery, it is recommended to examine the levator ani, piriformis and obturator internus muscles, so as to identify trigger points on the pathway of the synthetic mesh (EO). Pelvic floor muscle training with muscle relaxation is recommended when myofascial pain syndrome is associated with chronic postoperative pain following POP surgery (EO). After failure of pelvic floor muscle training (3 months), it is recommended to discuss surgical removal of the synthetic mesh, during a multidisciplinary discussion group meeting (EO). Partial removal of synthetic mesh is indicated when a trigger point is located on the pathway of the mesh (EO). Total removal of synthetic mesh should be discussed during a multidisciplinary discussion group meeting when diffuse (no trigger point) chronic postoperative pain occurs following POP surgery, with or without central sensitization or neuropathic pain syndromes (EO). POSTOPERATIVE DYSPAREUNIA: When de novo postoperative dyspareunia occurs after POP surgery, surgical removal of the mesh should be discussed (EO). VAGINAL MESH EXPOSURE: To reduce the risk of vaginal mesh exposure, when hysterectomy is required during sacral colpopexy, subtotal hysterectomy is recommended (grade C). When asymptomatic vaginal macroporous monofilament polypropylene mesh exposure occurs, systematic imaging is not recommended. When vaginal polyester mesh exposure occurs, pelvic +/- lumbar MRI (EO) should be used to look for an abscess or spondylodiscitis, given the greater risk of infection associated with this type of material. When asymptomatic vaginal mesh exposure of less than 1 cm2 occurs in a woman with no sexual intercourse, the patient should be offered observation (no treatment) or local estrogen therapy (EO). However, if the patient wishes, partial excision of the mesh can be offered. When asymptomatic vaginal mesh exposure of more than 1 cm2 occurs or if the woman has sexual intercourse, or if it is a polyester prosthesis, partial mesh excision, either immediately or after local estrogen therapy, should be offered (EO). When symptomatic vaginal mesh exposure occurs, but without infectious complications, surgical removal of the exposed part of the mesh by the vaginal route is recommended (EO), and not systematic complete excision of the mesh. Following sacral colpopexy, complete removal of the mesh (by laparoscopy or laparotomy) is only required in the presence of an abscess or spondylodiscitis (EO). When vaginal mesh exposure recurs after a first reoperation, the patient should be treated by an experienced team specialized in this type of complication (EO). SUTURE THREAD VAGINAL EXPOSURE: For women presenting with vaginal exposure to non-absorbable suture thread following POP surgery with mesh reinforcement, the suture thread should be removed by the vaginal route (EO). Removal of the surrounding mesh is only recommended when vaginal mesh exposure or associated abscess is diagnosed. BLADDER AND URETERAL MESH EXPOSURE: When bladder mesh exposure occurs, removal of the exposed part of the mesh is recommended (grade B). Both alternatives (total or partial mesh removal) should be discussed with the patient and should be debated during a multidisciplinary discussion group meeting (EO).

RESUMO

OBJECTIVE: The aim of the study is to examine the effectiveness of extracorporeal shockwave therapy in reducing pain, improving functionality, joint range of motion, quality of life, fatigue, and health status self-perception in people with myofascial pain syndrome. METHODS: PubMed, the Cochrane Library, CINAHL, the Physiotherapy Evidence Database, and SPORTDiscus were systematically searched for only randomized clinical trials published up to June 2, 2022. The main outcome variables were pain, as reported on the visual analog scale and pressure pain threshold, and functionality. A quantitative analysis was conducted using the inverse variance method and the random effects model. RESULTS: Twenty-seven studies were included ( N = 595 participants in the extracorporeal shockwave therapy group). The effectiveness of extracorporeal shockwave therapy for relieving pain was superior for the extracorporeal shockwave therapy group compared with the control group on the visual analog scale (MD = -1.7 cm; 95% confidence interval = -2.2 to -1.1) and pressure pain threshold (mean difference = 1.1 kg/cm 2 ; 95% confidence interval = 0.4 to 1.7) and functionality (standardized mean difference = -0.8; 95% confidence interval = -1.6 to -0.04) with high heterogeneity. However, no differences were found between extracorporeal shockwave therapy and other interventions as dry needling, exercises, infiltrations, and lasers interventions. CONCLUSIONS: Extracorporeal shockwave therapy is effective in relieving pain and improving functionality in patients with myofascial pain syndrome compared with control and ultrasound therapy.

RESUMO

PURPOSE OF REVIEW: Chronic pelvic pain is much of a burden to those who suffer from it. Additionally, in many patients medical doctors, such as urologists are unable to identify a cause or clear pathology that can explain the pain. Still numerous patients and doctors keep on searching for a cause, focussing particularly on the pelvic organs. Lots of diagnostics and treatment methods are used but often without success. In recent years, we have gained increased insight into the mechanisms of pain and adapted the terminology accordingly. RECENT FINDINGS: Two aspects of chronic pelvic pain have gained more attention. First, the myofascial aspects, especially the role of the pelvic floor muscles in maintaining the pain and as a therapeutic option. Second, the role of the brain and the psychological aspects intertwine with the pain and its consequences also open up for alternative management options. In terminology chronic pain is now included in the ICD-11, a historical change. Introducing chronic primary pain (no cause found) helps us to look away from the organ and deal with the patient as a whole human being. SUMMARY: The findings reported here are helpful for your daily practice. Looking from a broad perspective gives the patient the feeling of being seen and heard. Working together in a multidisciplinary team makes your work easier and gives more satisfaction. VIDEO ABSTRACT: http://links.lww.com/COU/A44.

RESUMO

OBJECTIVE: To examine for the in vitro existence of contractile nodules on the taut band of muscle fibers where myofascial trigger points (MTrPs) are located (using cell culture). METHODS: Sixteen male Sprague-Dawley rats (7 weeks old) were randomly divided into experimental and control groups. A blunt striking injury and eccentric exercise were applied to the gastrocnemius muscle of rats in the experimental group once a week for 8 weeks to establish an MTrP model. Subsequently, the rats were reared normally and rested for 4 weeks. After modeling, the skeletal muscles at the MTrPs (and non-MTrPs at the same anatomical position) were extracted from the two groups of rats for in vitro cell culture experiments of single muscle fibers. Potential contractile nodules in the MTrP group were exposed to different concentrations of acetylcholinesterase, whereas non-MTrP cells were exposed to acetylcholine. The morphological changes of muscle cells in each group were observed. RESULTS: By culturing MTrP cells in vitro, large contractile nodules remained in single MTrP muscle fibers, whereas some contractile nodules were twisted and deformed. After the addition of different acetylcholinesterase concentrations, no obvious morphological changes were observed in the contractile nodules in the MTrP group. After the non-MTrP cells were exposed to different acetylcholine concentrations, no significant morphological changes were observed in the single muscle fibers. CONCLUSION: MTrP cells can continue to maintain contractile morphology in vitro, but whether the recovery of such contractile nodules is related to acetylcholine remains uncertain.

RESUMO

OBJECTIVE: The objective of this study was to compare trigger point (TrP) dry needling, TrP electroacupuncture and motor point electroacupuncture of the trapezius muscle for the treatment of myofascial pain syndrome (MPS). METHODS: This randomised clinical trial included 90 patients divided into three groups. Group 1 was treated with dry needling of TrPs, group 2 with intramuscular electrical stimulation of TrPs, and group 3 with electroacupuncture of motor points and/or the spinal accessory nerve. Each group received seven treatment sessions. The outcomes were the pain score measured by visual analogue scale (VAS) and quality of life evaluated by the 12-item short form (SF-12) health questionnaire. We compared the pain outcome over serial time points using growth curve analysis methods. RESULTS: Participants in the three groups experienced significant improvements in pain scores over time. The average pain level of participants in group 3 across the repeated assessments was 0.98 units lower than in group 1 (mean difference (95% confidence interval (CI) = 1.74-0.23)), p = 0.012). There were no significant differences in pain scores between participants in groups 1 and 2, and there were no significant differences in quality of life across the three groups at the end of the treatment period. CONCLUSION: Our results provide evidence that electrical stimulation of motor points and/or of the spinal accessory nerve may be superior in terms of pain relief (but not quality of life) to dry needling and possibly electrical stimulation of trigger points for the management of MPS involving the trapezius. TRIAL REGISTRATION NUMBER: TRIAL-RBR-43R7RF (Brazilian Clinical Trials Registry).

RESUMO

BACKGROUND AND OBJECTIVE: Myofascial pain syndrome (MPS) is a chronic musculoskeletal disorder characterized by the presence of trigger points. Among the treatment options, botulinum toxin injections have been investigated. The aim of this paper was to provide a synthesis of the evidence on intramuscular botulinum toxin injections for upper back MPS. DATABASES AND DATA TREATMENT: A systematic review of the literature was performed on the PubMed, Scopus and Cochrane Library, using the following formula: ("botulinum") AND ("musculoskeletal") AND ("upper back pain") OR ("myofascial pain"). RESULTS: Ten studies involving 651 patients were included. Patients in the control groups received placebo (saline solution) injections, anaesthetic injections + dry needling or anaesthetic injections. The analysis of the trials revealed modest methodological quality: one "Good quality" study, one "Fair" and the other "Poor". No major complications or serious adverse events were reported. Results provided conflicting evidence and did not demonstrate the superiority of botulinum toxin over comparators. Most of the included trials were characterized by a small sample size, weak power analysis, different clinical scores used and non-comparable follow-up periods. Even if there is no conclusive evidence, the favourable safety profile and the positive results of some secondary endpoints suggest a potentially beneficial action in pain control and quality of life. CONCLUSION: The currently available studies show conflicting results. Their overall low methodological quality does not allow for solid evidence of superiority over other comparison treatments. Further insights are needed to properly profile patients who could benefit more from this peculiar injective approach. SIGNIFICANCE: The randomized controlled trials included in this review compared using botulinum toxin to treat upper back MPS with placebo or active treatments (e.g., dry needling or anaesthetics) showing mixed results overall. Despite the lack of clear evidence of superiority, our study suggests that the use of botulinum toxin should not be discouraged. Its safety profile and encouraging results in pain control, motor recovery and disability reduction make it an interesting treatment, particularly in the subset of patients with moderate to severe chronic pain and active trigger points. To support the safety and efficacy of botulinum toxin, further high-quality studies are needed.

RESUMO

BACKGROUND: Myofascial pain syndrome (MPS) has an impact on physical health and quality of life for patients, with various noninvasive methods used for relieving myofascial pain. The authors aimed to compare the effectiveness of different noninvasive therapeutic interventions for MPS. MATERIALS AND METHODS: The authors searched PubMed, Embase, CINAHL Complete, Web of Science, Cochrane, and Scopus to identify randomized controlled trials describing the effects of any noninvasive treatments in patients with MPS. The primary outcome was pain intensity, while pressure pain threshold and pain-related disability were secondary outcomes. RESULTS: The analysis included 40 studies. Manual therapy [mean difference (MD) of pain: -1.60, 95% CI: -2.17 to -1.03; MD of pressure pain threshold: 0.52, 95% CI: 0.19 to 0.86; MD of pain-related disability: -5.34, 95% CI: -8.09 to -2.58], laser therapy (MD of pain: -1.15, 95% CI: -1.83 to -0.46; MD of pressure pain threshold: 1.00, 95% CI: 0.46 to 1.54; MD of pain-related disability: -4.58, 95% CI: -7.80 to -1.36), extracorporeal shock wave therapy (MD of pain: -1.61, 95% CI: -2.43 to -0.78; MD of pressure pain threshold: 0.84, 95% CI: 0.33 to 1.35; MD of pain-related disability: -5.78, 95% CI: -9.45 to -2.12), and ultrasound therapy (MD of pain: -1.54, 95% CI: -2.24 to -0.84; MD of pressure pain threshold: 0.77, 95% CI: 0.31 to 1.22) were more effective than no treatment. CONCLUSION: Our findings support that manual therapy, laser therapy, and extracorporeal shock wave therapy could effectively reduce pain intensity, pressure pain threshold, and pain-related disability with statistical significance when compared with placebo. This finding may provide clinicians with appropriate therapeutic modalities for patients with MPS among different scenarios.

RESUMO

PURPOSE: This study aims to examine the effect of deep tissue massage (DTM) on the myofascial trigger point (MTrP) number, neck range of motion (ROM), pain, disability and quality of life in patients with Myofacial pain syndrome (MPS). METHODS: The study involved patients with MPS between the ages of 20-57. The patients were randomly divided into two groups: the control group (n = 40) and the study group (n = 40). Transcutaneous Electrical Neuromuscular Stimulation (TENS), hotpack and ultrasound were applied to 40 patients in the control group. The study group was also administered DTM for 12 sessions in addition to TENS, hotpack and ultrasound applications. Neck pain and disability scale (NPDS) for a neck disability, universal goniometer for neck ROM, MTrP count using manual palpation, Short Form 36 (SF-36) for quality of life and severity of neck pain were evaluated using a visual analog scale (VAS). All patients were evaluated before and after treatment. RESULTS: It was found that the DTM group has statistically more improvement than the control group for VAS, NPDS and SF-36. Moreover, although there was a significant improvement in favour of the study group for extension, lateral flexion, right rotation and left rotation in the neck ROM, there was no significant difference in flexion measurements between the study and control group. CONCLUSION: In addition to the traditional rehabilitation program, DTM is effective on neck ROM, pain, disability and quality of life. Therefore, DTM treatment is a safe and inexpensive treatment method that can be applied in patients with MPS.

RESUMO

OBJECTIVES: Post cholecystectomy pain syndrome can cause significant distress, impairs quality of life and exacerbations often result in emergency visits. Poorly controlled postoperative pain is a recognized cause of persistent postsurgical pain. Abdominal myofascial pain syndrome is an underdiagnosed cause of persistent pain in this cohort. The objective was to estimate the incidence of poorly controlled postoperative pain in the first 48 h after surgery and the likelihood of developing persistent pain at 12 months. METHODS: The patients undergoing laparoscopic cholecystectomy at a tertiary unit were consented for participation in a prospective service evaluation. A telephone review was performed at three, six and twelve months after surgery. Incidence of poorly controlled pain in the first 48 h after surgery was assessed. Patients with persistent pain were referred to the pain clinic. RESULTS: Over a six-month period, 200 patients were assessed. Eleven patients were excluded (5.5 %). Twelve patients were lost to follow-up (6.6 %, 12/189). Patient satisfaction with acute postoperative pain management was low in 40 % (76/189). Poorly controlled postoperative pain was reported by 36 % (68/189) of patients. Incidence of persistent pain was 29 % (54/189) at 12 months post-surgery. Over half of patients with persistent pain (63 %, 34/54) reported poorly controlled postoperative pain. A somatic source was diagnosed in 54 % (29/54) with post cholecystectomy pain syndrome. CONCLUSIONS: Poorly controlled postoperative pain was reported by a third of patients. Persistent pain was present in 29 % at twelve months post-surgery. Abdominal myofascial pain syndrome should be considered as a differential diagnosis in post cholecystectomy pain syndrome.

RESUMO

INTRODUCTION AND HYPOTHESIS: Pelvic floor myofascial pain (PFMP) is a common but underrecognized component of chronic pelvic pain and pelvic floor disorders symptoms with limited, well-studied treatment modalities. Our objective was to determine the effect of vaginal cryotherapy on PFMP with palpation. METHODS: Following a standardized PFMP screening examination, individuals with a pain score ≥4/10 in ≥1 of four muscle groups were invited to participate in a randomized controlled trial comparing patients undergoing vaginal cryotherapy with controls. Participants in both arms could choose to participate in a single in-office treatment; a 2-week, at-home daily treatment; or both. RESULTS: Between March 2019 and September 2021, a total of 163 participants were enrolled and randomized: 80 to cryotherapy, and 83 to the control group. Sixty-three (28 cryotherapy; 35 controls) completed in-office treatment and 56 (32 cryotherapy; 24 controls) completed at-home therapy. In the in-office comparison, mean pain scores decreased significantly in both arms: cryotherapy (5.13 vs 4.10; p=0.02) and controls (5.60 vs 4.72; p<0.01), with a similar magnitude of reduction between arms (p=0.75). In the at-home comparison, mean pain scores decreased significantly in the cryotherapy arm (6.34 vs 4.75; p<0.01), and nonsignificantly in the control arm (5.41 vs 4.66; p=0.07), resulting in a nonsignificant difference between arms (p=0.14). CONCLUSIONS: Pelvic floor myofascial pain with palpation improved following both a single cryotherapy session and 2 weeks of daily cryotherapy. Interestingly, pain scores also improved with room temperature therapy. Whether these findings reflect a therapeutic effect of both cold and room temperature intravaginal therapy or a placebo effect is unclear but should be explored in larger studies.

RESUMO

Myofascial pain syndrome is a chronic pain disorder characterized by myofascial trigger points (MTrPs). Quantitative ultrasound (US) techniques can be used to discriminate MTrPs from healthy muscle. In this study, 90 B-mode US images of upper trapezius muscles were collected from 63 participants (left and/or right side(s)). Four texture feature approaches (individually and a combination of them) were employed that focused on identifying spots, and edges were used to explore the discrimination between the three groups: active MTrPs (n = 30), latent MTrPs (n = 30), and healthy muscle (n = 30). Machine learning (ML) and one-way analysis of variance were used to investigate the discrimination ability of the different approaches. Statistically significant results were seen in almost all examined features for each texture feature approach, but, in contrast, ML techniques struggled to produce robust discrimination. The ML techniques showed that two texture features (i.e., correlation and mean) within the combination of texture features were most important in classifying the three groups. This discrepancy between traditional statistical analysis and ML techniques prompts the need for further investigation of texture-based approaches in US for the discrimination of MTrPs.

RESUMO

BACKGROUND: Myofascial pain syndrome (MPS) is a common source of pain in primary care or pain clinics. There are many different ways to manage and treat MPS, such as physical exercise, trigger points massage, and dry needling. OBJECTIVE: The objective of this overview is to highlight and discuss the evidence-based treatment of myofascial pain by dry needling in patients with low back pain. METHODS: A systematic review was made based on meta-analysis (MA) and randomized controlled trials (RCTs) related to dry needling treatment for myofascial pain in patients with lumbar pain, published from 2000 to 2023. RESULTS: A total of 509 records were identified at first. Seventy were published before 2000, so they were excluded. From the remaining 439 studies, ninety-two were RCTs or MA, of which 86 additional studies were excluded for the following reasons: not related to dry needling treatment (n = 79), not published in English (n = 4), duplicated (n = 1), project protocol (n = 1), and not related to myofascial pain (n = 1). So, this review was based on 4 RCTs and two MA. These studies compared dry needling efficacy to other treatments, such as acupuncture, sham dry needling, laser therapy, physical therapy, local anesthetic injection, ischemic compression, and neuroscience education. Despite outcomes and follow-up period varied between them, they showed that dry needling can decrease post-intervention pain intensity and pain disability. CONCLUSION: Dry needling is an effective procedure for the treatment of myofascial pain in patients with acute and chronic low back pain. Further high-quality studies are needed to clarify the long-term outcomes.


ANTECEDENTES: A síndrome dolorosa miofascial (SDM) é uma fonte comum de dor em centros primários de atenção à saúde ou nas clínicas de dor. Existem muitas formas diferentes de manejar e tratar a SDM, como o exercício físico, a massagem dos pontos de gatilho e o agulhamento a seco. OBJETIVO: O objetivo desta revisão é destacar e discutir o tratamento baseado em evidências da dor miofascial por agulhamento a seco em doentes com dor lombar. MéTODOS: Foi realizada uma revisão sistemática baseada em metanálises (MA) e ensaios clínicos randomizados (RCTs) relacionados ao tratamento da dor miofascial com agulhamento a seco em pacientes com dor lombar, publicados de 2000 a 2023. RESULTADOS: Foram identificados, inicialmente, um total de 509 registos. Setenta deles, publicados antes de 2000, foram excluídos. Dos 439 estudos restantes, 92 eram RCTs ou MA, dos quais 86 foram excluídos pelas seguintes razões: não relacionados a tratamento com agulhamento a seco (n = 79), não publicados em inglês (n = 4), duplicados (n = 1), protocolo de projeto (n = 1) e não relacionados com dor miofascial (n = 1). Assim, esta revisão baseou-se em quatro RCTs e duas MA. Esses estudos compararam a eficácia do agulhamento seco com outros tratamentos, tais como acupuntura, agulhamento a seco "sham", terapia com laser, fisioterapia, injeção de anestésico local, compressão isquêmica e educação em neurociências. Apesar de os resultados e o período de seguimento variarem entre os estudos, os estudos demonstram que o agulhamento a seco pode diminuir a intensidade da dor pós-intervenção e a incapacidade relacionada à dor. CONCLUSãO: O agulhamento a seco é um procedimento eficaz para o tratamento da dor miofascial em pacientes com dor lombar aguda e crônica. Mais estudos são necessários para esclarecer sua eficácia a longo prazo.

RESUMO

BACKGROUND: Few reports have described multidisciplinary treatment, including extracorporeal shock wave therapy, for patients with refractory chronic tension-type headache. In this study, we conducted multidisciplinary treatment for a patient with chronic tension-type headache who suffered from chronic headache refractory to treatment. CASE PRESENTATION: The patient was a 45-year-old Japanese male suffering from 20 years of headache. As his headache had worsened recently, he visited a local clinic. With the diagnosis of suspected tension-type headache, its treatment was unsuccessful and he was referred to our hospital. The neurology department confirmed the tension-type headache and prescribed another medication, but he showed no improvement. Then, the patient was referred to the rehabilitation medicine department for consultation. At the initial visit, we identified multiple myofascial trigger points in his bilateral posterior neck and upper back regions. At the initial visit, he was prescribed 10 mL of 1% lidocaine injected into the muscles in these areas. In addition, he received 2000 extracorporeal shock wave therapy into bilateral trapezius muscles, and was instructed to take oral Kakkonto extract granules, benfotiamine, pyridoxine hydrochloride, and cyanocobalamin. Cervical muscle and shoulder girdle stretches and exercises were also recommended. At follow-up treatment visits, we used extracorporeal shock wave therapy to bilateral trapezius muscles, which led to immediate pain relief. After 11 weeks, he was not taking any medication and his headache was subjectively improved and his medical treatment ended. CONCLUSION: A patient with chronic tension-type headache refractory to regular treatment was successfully treated with a multimodal approach including extracorporeal shock wave therapy in addition to standard treatment. For patients with tension-type headache accompanied by myofascial trigger points, it may be recommended to promptly consider aggressive multimodal treatment that includes extracorporeal shock wave therapy.

RESUMO

OBJECTIVE: Recently, the DC/TMD has become an essential tool for the diagnosis of temporomandibular disorders (TMD). However, as they fail to include functional activities, new assessment proposals have emerged, such as the isometric contraction test (IC test) of the masticatory muscles, which uses muscle contractions to identify muscular TMD. This study aimed to determine the test-retest reliability of the IC test. METHODS: A total of 64 participants (40 women and 24 men) completed the IC test administered by two different physical therapists on two non-consecutive days. Cohen's kappa (k), PABAK, and percent agreement (PA) between days were estimated. RESULTS: The IC test showed good to excellent test-retest reliability values (k>0.77; PABAK>0.90), both globally and individually for the muscles evaluated, and PA>90%, therefore above the thresholds for clinical applicability. However, the global assessment of myofascial pain and the evaluation of the medial pterygoid muscle showed slightly lower reliability values. CONCLUSION: The IC test is reliable for the assessment of subjects with muscular TMD, both in terms of the global assessment and the evaluation of each muscle, which supports its clinical applicability. Care should be taken when assessing myofascial pain globally and when evaluating the medial pterygoid in all types of pain.
