Clinical efficacy of electroacupuncture-like magnetic therapy compared to conventional transcutaneous electrical nerve stimulation in individuals with carpal tunnel syndrome.

This study aimed to evaluate the clinical efficacy of an electroacupuncture-like magnetic therapy (ELMT) and conventional transcutaneous electrical nerve stimulation (TENS) in patients with carpal tunnel syndrome (CTS). A prospective randomized controlled trial in single-centre was conducted. Thirty-four CTS patients confirmed by electrodiagnostic study were randomized into TENS or ELMT group and completed a six-week treatment program. TENS or ELMT treatment was applied on acupuncture point PC-6 (Neiguan) and one selected hand acupoint. Therapeutic exercises were also included after the electrophysical modality. Their physical signs, motor and sensory performances, Boston Carpal Tunnel Questionnaire (BCTQ) scores, and results of electrodiagnostic study were evaluated. After treatments, both groups demonstrated significantly decreased BCTQ scores and positive rate of Tinel's sign in the major symptomatic side, which indicated improvements in the symptom severity and physical functions. Significant increases in distal sensory amplitude and nerve conduction velocity of the median nerve were only found in the ELMT group. Our study found either conventional TENS or ELMT plus therapeutic exercises could improve the symptomatology and physical provocation sign of CTS. The ELMT has additional improvement in the nerve conduction in patients with CTS.

Fu's subcutaneous needling as an adjunctive therapy for diaphragmatic dysfunction in a critically ill patient with severe neurologic disability: A case report.

RATIONALE: Diaphragmatic dysfunction is prevalent among intensive care unit patients. The use of Fu's subcutaneous needling (FSN) for respiratory problems is a new issue and few study has been conducted so far. PATIENT CONCERNS: Despite conventional treatments, the patient continued using noninvasive ventilation after discharge from the intensive care unit due to diaphragmatic dysfunction. DIAGNOSIS: Diaphragmatic dysfunction. INTERVENTIONS: After the myofascial trigger points were confirmed in the neck, chest, and abdomen area, FSN therapy was performed using disposable FSN needles. FSN needles were penetrated into the subcutaneous layer. OUTCOMES: The patient dyspnea and tachypnea improved, and noninvasive ventilation time dropped significantly. The patient was successfully weaned from the ventilator after 3 sessions of FSN therapy, and there was an increase in diaphragmatic excursion and tidal fraction of the diaphragm via the ultrasound imaging. We found no evidence of relapse 12 months after treatment. LESSONS: FSN therapy has potential as an alternative strategy for patients with diaphragmatic dysfunction and severe neurologic disabilities who do not respond well to conventional therapies, but further research is still required to establish the effects of FSN on diaphragmatic function.

Efficacy of Fu's Subcutaneous Needling on Sciatic Nerve Pain: Behavioral and Electrophysiological Changes in a Chronic Constriction Injury Rat Model.

Fu's subcutaneous needling (FSN), an invented acupuncture technique from traditional Chinese medicine, is used worldwide for pain relief. However, the mechanisms of action are still not fully understood. During FSN treatment, the FSN needle is inserted and retained in the subcutaneous tissues for a long duration with a swaying movement. However, challenges arise from maintaining a posture while manipulating FSN in animal models (e.g., rats) for researchers. Uncomfortable treatment can lead to fear and resistance to FSN needles, increasing the risk of injury and may even affect research data. Anesthesia may also affect the study results too. Hence, there is a need for strategies in FSN therapy on animals that minimize injury during the intervention. This study employs a chronic constriction injury model in Sprague-Dawley rats to induce neuropathic pain. This model replicates the pain induced by nerve injury observed in humans through surgical constriction of a peripheral nerve, mimicking the compression or entrapment seen in conditions such as nerve compression syndromes and peripheral neuropathies. We introduce an appropriate manipulation for easily inserting an FSN needle into the subcutaneous layer of the animal's body, including needle insertion and direction, needle retention, and swaying movement. Minimizing the rat's discomfort prevents the rat from being tense, which causes the muscle to contract and hinder the entry of the needle and improves the study efficiency.

Fu's Subcutaneous Needling for Knee Osteoarthritis Pain.

Fu's subcutaneous needling (FSN) is a new acupuncture and dry needling technique based on traditional Chinese medicine. It rapidly produces long-lasting effects in soft tissue injuries, particularly in painful musculoskeletal conditions, by providing stimulation primarily in the subcutaneous area. Osteoarthritis (OA) is the most common joint disease in adults worldwide and is often accompanied by a painful syndrome of structural changes in the peripheral joints of the knee. However, the etiology of OA pain is not fully understood, though myofascial trigger points (MTrPs) are commonly found in the lower limb muscles (so-called "tightened muscles") of patients with knee OA. FSN has been used in many fields for the treatment of acute pain problems and can relieve muscle contraction from MTrPs, thereby improving the local circulation. This study recruited patients with pain from knee OA into an FSN group or a transcutaneous electrical nerve stimulation (TENS) group with three treatment sessions and a follow-up over the course of 2 weeks. The results showed that FSN was effective in treating soft tissue pain around the knee with OA. This study aimed to establish and visualize three key technical indicators during FSN therapy, including the FSN needle insertion point and layer; the frequency and duration of the swaying movement; and the manipulation of the reperfusion approach. These findings have great potential for future applications in myofascial pain treatment, especially for pain management. Following this protocol could enhance FSN skills.

Treatment of postsurgical trigeminal neuralgia with Fu's subcutaneous needling therapy resulted in prompt complete relief: Two case reports.

RATIONALE: Trigeminal neuralgia is a recurrent unilateral transient electroshock-like pain. Fu's subcutaneous needling (FSN), used to treat the musculoskeletal problems, has not been reported in this field. PATIENT CONCERNS: The pain extent of case 1 had no reduction after the previous microvascular decompression, the pain of case 2 relapsed 4 years after the microvascular decompression. DIAGNOSES: Postsurgical trigeminal neuralgia. INTERVENTIONS: FSN therapy was applied on the muscles around the neck and face area, which the myofascial trigger points were palpated in these muscles. The FSN needle was inserted into the subcutaneous layer and the needle tip was pointed toward the myofascial trigger point. OUTCOMES: The following outcome measurements were observed before and after treatment, including numerical rating scale, Barrow Neurology Institute Pain Scale scores, Constant Face Pain Questionnaire scores, Brief Pain Inventory-Facial scores, Patient Global Impression of Change scores, and medication dosage. The follow-up surveys were made after 2 and 4 months respectively. The pain of Case 1 was significantly reduced after 7 times FSN treatments and the pain of Case 2 was even disappeared after 6 times FSN treatments. LESSONS: This case report suggested that FSN can relieve postsurgical trigeminal neuralgia safely and effectively. Clinical randomized controlled studies are needed to be further conducted.

Efficacy of Fu's Subcutaneous Needling in Treating Soft Tissue Pain of Knee Osteoarthritis: A Randomized Clinical Trial.

Purpose: Fu's subcutaneous needling (FSN) is a new acupuncture technique that produces a long-lasting effect in soft-tissue injuries. In patients with degenerative knee osteoarthritis (OA), myofascial trigger points (MTrPs) are common in the lower-limb muscles. In this randomized clinical trial, we evaluated the immediate, 1-week and 2-week effectiveness of FSN therapy in the treatment of degenerative knee OA. Patients and methods: We randomly divided 32 patients with knee OA into the FSN group (mean age: 65.73 ± 6.79 years) or the transcutaneous electrical nerve stimulation (TENS) group (mean age: 62.81 ± 5.72 years). The pressure pain threshold (PPT) and tissue hardness (TH) of the muscle and tendon attachment sites, knee range of motion, and physical ability (average walking speed) were measured. The subjective pain intensity index, Western Ontario and McMaster Universities OA Index (WOMAC), and Lequesne index were used to determine the efficacy of FSN on MTrP-induced soft-tissue pain compared with that of TENS. Results: A significantly greater improvement in pain qualities in the VAS (p < 0.05) was found in the FSN group. Moreover, in muscle and tendon qualities (including PPT and TH), a significant difference in the PPT of the quadriceps muscle (p < 0.05) was also observed among the immediate treatments in the FSN group. As for the functional index questionnaire assessment, the FSN group exhibited significant improvements among the immediate, 1-week and 2-week efficacies in terms of WOMAC (p < 0.05) and Lequesne index scores (p < 0.05). Conclusion: FSN was effective in treating soft-tissue pain in degenerative knee OA in terms of alleviating pain, strengthening walking ability, and improving overall functional performance. Pain relief was the primary benefit of FSN and a significant correlation between pain relief and knee joint mobility improvement was found.

Rapid Improvement in Neck Disability, Mobility, and Sleep Quality with Chronic Neck Pain Treated by Fu's Subcutaneous Needling: A Randomized Control Study.

Background: Chronic neck pain is a common musculoskeletal disorder caused by overuse of neck and upper back muscles or poor posture, and it is commonly combined with a limited range of motion in the neck and shoulders. Most cases will recover within a few days; however, the symptoms often recur easily. Fu's subcutaneous needling (FSN) is a new therapeutic approach used to treat patients with chronic neck pain. However, there is no solid evidence to support the effectiveness of FSN on chronic neck pain and disability. Methods: Participants (n = 60) with chronic neck pain for more than 2 months with pain intensity scored by visual analog scale (VAS) more than five were enrolled in this trial. Participants were equally randomized into the FSN or transcutaneous electrical nerve stimulation (TENS) group who received interventions once a day on day 1, day 2, and day 4. They were assessed by outcome measurements during pre- and post-treatment and followed up for 15 days. Results: The VAS was immediately reduced in the FSN and TENS groups and sustained for 15 days of follow-up (all P < 0.001). The immediate effects were also observed as the pressure pain threshold increased in the FSN group on day 2 (P=0.006) and day 4 (P=0.023) after treatment, and tissue hardness decreased by FSN on day 1 and day 2 after treatment (both P < 0.001). FSN and TENS treatment improved neck disability and mobility; moreover, FSN promoted participants to receive better sleep quality, as determined by PSQI assessment (P=0.030). TENS had no benefit on sleep quality. Conclusion: FSN was able to relieve pain and relax muscle tightness. Notably, FSN significantly improved neck disability and mobility and enhanced sleep quality. These findings demonstrated that FSN could be an effective alternative treatment option for patients with chronic neck pain. Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT03605576, registered on July 30, 2018.

Effects of Fu's subcutaneous needling on mitochondrial structure and function in rats with sciatica.

To observe the effects of Fu's subcutaneous needling (FSN) and acupuncture treatment on the mitochondrial structure and function of the skeletal muscle tissue of rats with sciatica. Forty Sprague-Dawley rats were divided into control, model, acupuncture, and FSN groups (10 each) according to a random number table. The control group was left untreated. Rats in the FSN group were treated with FSN once every 2 days for three times, respectively (days 1, 3, 5, and 7), to cooperate with reperfusion approach. The acupuncture group was treated at the same timeline as that of the FSN group. Changes in the mechanical pain threshold, mitochondrial ultrastructure, mitochondrial citrate synthase (CS) activities, mitochondrial respiratory chain complex II, and mitochondrial COX- I protein expression in the skeletal muscle of rats treated with different treatments were compared with those of the model group. The pain thresholds of the rats were remarkably higher after FSN treatment and acupuncture, and the pain threshold of the FSN group was higher than that of the acupuncture group. Compared with the control group, the mitochondria of the model group had a damaged ultrastructure, were arranged in a disorganized manner, accumulated under the basement membrane, and appeared vacuolated with autophagosomes. The state of mitochondria in the FSN group was close to that in the control group and was remarkably better than that in the acupuncture group. The activities of mitochondrial CS and respiratory chain complex II in the skeletal muscle of the treated rats decreased compared with the control group (p < 0.05), and their levels were better in the FSN group than in the acupuncture group (p < 0.05). FSN treatment for 1 week considerably improved the pain thresholds and improved the skeletal muscle mitochondrial ultrastructure and mitochondrial function in rats with sciatica.

Efficacy of Fu's Subcutaneous Needling on Myofascial Trigger Points for Lateral Epicondylalgia: A Randomized Control Trial.

Lateral epicondylalgia (LE), a common overuse syndrome of the extensor muscle and tendons on the lateral epicondyle, causes persistent severe musculoskeletal pain on the outer part of the elbow. Fu's subcutaneous needling (FSN), a newly invented subtype of acupuncture and dry needling, is a new trend and potential treatment of LE by targeting the myofascial trigger points (MTrPs). However, no scientific evidence is available to support this method. This study aims to evaluate the distal FSN treatment on the LE by measuring pain-related scales, such as visual analog scale (VAS), pressure pain threshold (PPT), muscle tissue hardness (TH), pain-free grip (PFG), and the functional outcome by a patient-rated tennis elbow evaluation (PRTEE) questionnaire study. A total of 60 LE patients were randomly divided into FSN (n = 30) and transcutaneous electrical nerve stimulation (TENS, n = 30) as the control group. Every subject was treated with three regimens and followed up for 15 days. Results showed that FSN has an immediate effect on VAS, PPT, TH, and PFG. Moreover, sustained effects on pain relief were followed up to 15 days. Pain remission was consistent with long-term PRTEE results. Overall, FSN is a safe and efficient therapy option for LE, significantly improving pain relief and activity difficulty with immediate, short-term, and long-term effectiveness. This trial is registered with ClinicalTrials.gov NCT03605563.

Evaluating Effectiveness of Fu's Subcutaneous Needling for the Pain Nature and Quality of Life in Patients with Knee Osteoarthritis: A Study Protocol of Randomized Clinical Trial.

BACKGROUND: Knee osteoarthritis (OA) is a common clinical disease. Knee pain is the major symptom of knee OA and the primary reason why patients seek treatment. Fu's subcutaneous needling (FSN) has been used to treat knee OA for more than 20 years. However, the establishment of treatment methods and rigorous evaluation of FSN's efficacy are still lacking. A randomized single-blind clinical trial will be conducted to evaluate whether FSN treatment can immediately alleviate pain due to knee OA surrounding the patella and the curative effective of 1-week and 2-week treatments. In addition, the feasibility and initial effect of FSN treatment for patients with knee OA will be discussed. MATERIALS AND METHODS: Patients with confirmed knee OA, as diagnosed by doctors using X-ray films or from clinical symptoms, who are over 50 years old will be participants recruited. They will be randomly assigned either FSN treatment or transcutaneous electrical nerve stimulation treatment. In addition, their pressure pain threshold, muscle tone of lower leg muscle, and physical ability will be measured. Participants will be asked to complete the questionnaires of Western Ontario and McMaster Universities Osteoarthritis Index and Lequesne' index as the measurements for quality of life. RESULTS: The findings of this study will reveal whether FSN or transcutaneous electrical nerve stimulation is clinically efficacious for treating pain due to knee OA, with respect to muscle stiffness, gait, dynamic balance, the pressure pain threshold, and quality of life before and after treatment. STUDY REGISTRATION: This study is approved by the Research Ethics Committee of China Medical University & Hospital, Taichung, Taiwan (CMUH107-REC3-027) and registered at the ClinicalTrials.gov Protocol Registration and Results System (registration number NCT04356651).

Effects of 4-Week Inspiratory Muscle Training on Sport Performance in College 800-Meter Track Runners.

Background and objectives: Respiratory muscle fatigue is one of the important factors limiting sports performance due to the metaboreflex. This reflex will cause a decrease in blood flow to the extremities and accelerate exercising limb fatigue. Previous studies found that inspiratory muscle training (IMT) can effectively enhance the respiratory muscle endurance and reduce fatigue during long-duration exercise or aerobic exercise, thereby enhancing athletic performance. However, the mechanism between inspiratory muscle strength, change of limb blood flow and sports performance still requires investigation, especially in short-duration exercise, anaerobic or both aerobic and anaerobic exercise. The purpose of this study was to investigate the effects of 4-week inspiratory muscle training on respiratory muscle strength, limb blood flow change rate and sports performance in recreational 800-m college runners. Materials and Methods: Twenty healthy 800-m college runners randomized into the IMT group (11 subjects) and control group (9 subjects). IMT consisted of 30 inspiratory efforts twice daily, 5 days a week, with intensity at 50%, 60%, 70% and 80% of maximum inspiratory pressure (MIP) for 4 weeks, while a control group kept 50% of MIP for 4 weeks. An 800-m trial test, limb blood flow change rate by using Impedance Plethysmography, and MIP were as the outcome measured variables and be evaluated. All measured variables were assessed before and after 4-week IMT training. Two-way ANOVA was conducted for statistical analysis. Results: The results showed significantly interaction between groups and pre-posttest. IMT group significantly decreased limb blood flow change rate from 19.91 ± 11.65% to 9.63 ± 7.62% after received the IMT training program (p < 0.05). The MIP significantly improved from 112.95 ± 27.13 cmH2O to 131.09 ± 28.20 cm H2O in IMT group, and the 800-m trial test also shorted the running time from 162.97 ± 24.96 s to 156.75 ± 20.73 s. But the control group no significantly changed in MIP and 800-m trial test. Conclusions: Our results indicated that the 4-week IMT training (twice a day, 5 days a week) significantly improves participants' inspiratory muscle strength, 800-m running performance and decreases the limb blood flow change rate.

The Effectiveness of Acupuncture in the Treatment of Frozen Shoulder: A Systematic Review and Meta-Analysis.

BACKGROUND: Frozen shoulder (FS) is associated with pain, reduced range of motion (ROM), and shoulder function. The condition occurs in 2-5% of the population, and it is especially common around the age of 50 years. FS symptoms will recover after 1-4 years. Many patients turn to acupuncture in order to alleviate the FS symptoms. OBJECTIVE: In this review, we will investigate the efficiency of acupuncture as a FS treatment. METHODS: A literature search of acupuncture and FS-related keywords was performed in the following databases: PubMed, Cochrane Library, Embase, and Web of Science. Thirteen publications were included for a systematic review, and a meta-analysis was done using the following measurements: visual analogue scale (VAS) for pain, Constant-Murley Shoulder Outcome Score (CMS) for shoulder function, and active shoulder ROM including flexion, abduction, and external rotation. The Cochrane Collaboration's risk of bias tool and quality of evidence GRADE recommendations and STRICTA 2010 were used to grade the included publications. RESULTS: A meta-analysis on VAS pain score showed significant pain reduction, restoring CMS shoulder function, and flexion ROM in favor of acupuncture versus the control. In external rotation and abduction ROM, a meta-analysis was not significant. The most used acupoints are Jian Yu (LI15) and Jian Liao (TB14). CONCLUSIONS: The results indicate that acupuncture could be safe and effective for pain reduction, restoring shoulder function, and restoring flexion ROM for FS patients in the short term and midterm. However, the level of evidence was very low. More high-quality and longer studies are needed in order to robust the evidence.

Efficacy of Acupoints Dual-Frequency Low-Level Laser Therapy on Knee Osteoarthritis.

BACKGROUND: Knee osteoarthritis (OA) presented with knee pain and limitation of mobility is common, and it may become a chronic problem resulting in major loss of function, with related impaired activity of daily living. Current traditional therapy for knee OA includes pharmacological treatment and physiotherapy, but the efficacies are limited. An alternative noninvasive treatment low-level laser therapy (LLLT) applied to acupoints is still contradictory and the efficacy needs to be assessed. METHODS AND MATERIALS: We conduct the randomized double-blind control study to investigate the efficacy of a dual-frequency LLLT (combines red light (780 nm) and near-infrared light (830 nm)) in patients suffering knee OA. Participates were randomly assigned into active laser therapy (ALT) and placebo laser therapy (PLT) groups. Subjects in the ALT group were separately treated by laser apparatus at the three acupoints (SP9, SP10, and EX-LE2) on their knee joints under continuous radiation for 15 min at the maximum intensity, three times per week for four weeks. The PLT group used laser apparatus of the same model according to similar procedures without laser light emission. Outcome Measurements including visual analog scale (VAS), pain pressure threshold (PPT), and Lequesne index were used. RESULTS: A total of 30 subjects with two-sided knee OA in both groups completed the experiment. Statistically significant decreases were observed in the Lequesne index (5.27 ± 3.26 vs. 10.83 ± 3.83), conscious VAS 4 weeks after treatment (moving: 2.87 ± 1.13 vs. 5.67 ± 1.72; resting: 0.33 ± 0.62 vs. 2.67 ± 1.29), and the increase was noted in PPT (21.23 ± 1.82 kg vs. 13.02 ± 1.46 kg) in the ALT group compared with the PLT group. CONCLUSION: It appears that the knee OA pain and disability can be decreased after a dual-frequency LLLT applied to acupoints (SP9, SP10, and EX-LE2). The clinical efficacy of LLLT is highly related to the therapeutic settings of the laser apparatus; hence, more clinical trials with diffident parameter settings are needed to be further clarified.

A critical overview of the current myofascial pain literature - July 2020.

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.

Therapeutic effects of acupuncture on sensory ataxia after a cerebral hemorrhage: A case report.

INTRODUCTION: Sensory ataxia is a dysfunction of dynamic balance due to impairment of sensory input into the control of movement. The sequelae of stroke, such as hemiplegia, somatosensory impairment, and impaired balance may cause significant disability and may affect patients' quality of life. In addition to rehabilitation programs, acupuncture therapy has been applied to stroke patients and is recommended as a complementary therapy in stroke rehabilitation. PATIENT CONCERNS: A 70-year-old male had a sudden onset of conscious loss. The brain computed tomography showed intracerebral hemorrhage with subdural hemorrhage and subarachnoid hemorrhage. DIAGNOSIS: Intracerebral hemorrhagic stroke was diagnosed. INTERVENTIONS: He received craniotomy with hematoma evacuation immediately and waked up 3 weeks with bilateral hemiparesis (right side weaker than left), impaired position sensation and tactile perception in the right lower limb. He then began to receive rehabilitation therapy and had significant improvement in muscle strength and static balance, but no improvement in tactile perception of position sense in the right lower limbs and reached plateau. Then he received acupuncture therapies to Yongquan (KI1), Tongtien (BL7) and Houxi (SI3). OUTCOMES: The patient's walking ability recovered after receiving rehabilitation programs for 3 years, but the impairment in proprioception and dynamic balance persisted. The perception and dynamic balance had significantly improved after patient received acupuncture therapy, especially the acupuncture point of Yongquan (KI1). CONCLUSION: The clinical effect of acupuncture in combination with conventional rehabilitation therapy for neurological impairment recovery, improving activity of daily living performance and improving post-stroke imbalance was explored. We hope that this report can facilitate further well controlled quantitative objective studies on a big size of samples.

A critical overview of the current myofascial pain literature - January 2020.

We are starting 2020 with 6 basic research studies, 9 review articles, 14 dry needling/injection studies, and one manual therapy paper for a total of 30 new papers. Topics range from studies on mechanisms, inflammatory mediators in myofascial pain, fascia, screening, Platelet-rich plasma intramuscular injections, and temporal summation to clinical studies on patients with tension-type headache, chronic pelvic pain, knee osteoarthritis, plantar fasciitis, generalized musculoskeletal pain, neck pain, breast cancer, tendinopathies, thoracic outlet syndrome, and canine dry needling, among others.

Acupuncture and related interventions for carpal tunnel syndrome: systematic review.

OBJECTIVE: To synthesize evidence on the effectiveness of acupuncture and related therapies for primary carpal tunnel syndrome (CTS) by conducting a systematic review of randomized controlled trials (RCTs). DATA SOURCES: Nine databases were searched for potential RCTs from their inception till July 2019. REVIEW METHODS: RCTs which reported at least one of the three outcomes were included: symptom severity, functional status and pain. Included RCTs were appraised using the Cochrane Risk of Bias Tool. RESULTS: A total of 10 RCTs (728 participants) were included. Majority were at high risk of bias for blinding of participants, personnel and outcome assessors. When compared to conventional medications, manual acupuncture showed significant superior effect in reducing symptom than ibuprofen (mean difference (MD) on Symptom Severity Scale (SSS)) = -5.80, 95% confidence interval (CI): -7.95 to -3.65) and prednisolone (MD = -6.50, 95% CI: -10.1, -2.86). Electroacupuncture plus splinting was more effective in reducing symptom severity than splinting alone (SSS score: MD = -0.20, 95% CI: -0.36 to -0.03). Manual acupuncture showed significantly superior effect than ibuprofen in improving functional status (Functional Status Scale (FSS): MD = -1.84, 95% CI: -2.66 to -1.02). The combination of electroacupuncture and splinting showed more improvement in functional status compared to splinting alone (FSS: MD = -6.22, 95%CI: -10.7 to -1.71). Triple treatment of acupuncture, magnetic spectrum heat lamp and splinting showed stronger pain relief than splinting alone. CONCLUSION: For both symptom relief and function improvement, manual acupuncture is superior to ibuprofen while electroacupuncture plus splinting outperforms splinting alone. Limited evidence showed electroacupuncture's potential role in pain reduction.

Myofascial pain and treatment: Editorial a critical overview of the current myofascial pain literature - August 2019.

This quarter's overview of the myofascial pain literature includes quite a few basic research papers in addition to the usual high quantity of dry needling (DN) papers. Of particular interest are a study by Fischer and colleagues studying the role of mitochondrial functions in chronic trigger points (TrPs) (Fischer et al 2018), a study by Li and associates who conducted a quantitative proteomics analysis to identify biomarkers of chronic myofascial pain and therapeutic targets of dry needling in a rat model of TrPs (Li et al 2019), and a sonography study by Mitchell et al. looking into the distances from the skin to the pleura in the context of DN (Mitchell et al 2019). A total of 33 papers are included in this overview article. We welcome Dr. Jacob Thorp to our team of authors. Dr. Thorp is a US-based physical therapist. He is Professor and Founding Director of the Physical Therapy Program at Charleston Southern University in North Charleston, SC.

Characteristics of Traditional Chinese Medicine Use for Carpal Tunnel Syndrome.

Carpal tunnel syndrome (CTS) is a common musculoskeletal disorder and an occupational disease caused by repeated exercise or overuse of the hand. We investigated the characteristics of traditional Chinese medicine (TCM) use by practitioners in CTS patients, including demographic variables, socioeconomic status, previous medical conditions, health care use, and hospital characteristics for TCM health care. This cross-sectional study identified 25,965 patients newly diagnosed with CTS based on the first medical diagnosis recorded between 1999 and 2013 in the nationwide representative insurance database of Taiwan. The date of initial CTS diagnosis in outpatient data was defined as the index date, and four patients were excluded because of missing gender-related information. Patients who used TCM care as the first option at their diagnosis were classified as TCM users (n = 677; 2.61%), and all others were TCM non-users (n = 25,288; 97.4%). In the all variables-adjusted model, female patients had an adjusted odds ratio (OR; 95% CI) of TCM use of 1.35 (1.11-1.66). National Health Insurance (NHI) registration was associated with higher odds ratios of TCM use in central, southern, and eastern Taiwan than in northern Taiwan (ORs = 1.43, 1.86, and 1.82, respectively). NHI registration was associated with higher odds ratios of TCM use in rural cities than in urban cities (OR (95% CI) = 1.33 (1.02-1.72)). The TCM group had a 20% less likelihood of exhibiting symptoms, signs, and ill-defined conditions and injury and poisoning. The TCM group had a 56% lower likelihood of having diseases of the musculoskeletal system and connective tissue. Multi-level model outcomes were similar to the results of the all variables-adjusted model, except for the NHI registration outcome in rural and urban cities (OR [95% CI] = 1.33 [0.98-1.81]). Significant associations between the number of TCM visits and TCM use were observed in all logistic regression models. The study presented key demographic characteristics, health care use, and medical conditions associated with TCM use for CTS. Previous experience of TCM use may affect the use of TCM for CTS treatment. This information provides a reference for the allocations of relevant medical resources and health care providers.

Myofascial pain and treatment: Editorial.

The first article featured in this quarter's overview deserves special attention. Margalef and colleagues developed the first viable animal model of trigger points (TrPs). They also provided evidence of glycosaminoglycans (GAGs) near TrPs, which is a new finding that deserves further scientific inquiry (Margalef et al 2019). In 2011, Stecco et al. already mentioned a possible role of hyaluronan, which constitutes a subgroup of GAGs, in the etiology of myofascial pain (Stecco et al 2011). Mayoral Del Moral and colleagues published an excellent study that showed very good inter-examiner reliability for identifying subjects with MPS for identifying specific muscles (Mayoral Del Moral et al 2018). Sollmann and colleagues described a new and objective method to identify TrPs, using T2 mapping with quantitative MRI-based techniques (Sollmann et al 2016). As usual, many new dry needling (DN) studies, reviews, manual TrP papers and case reports are included. Finally, we would like to thank Dr. Michelle Finnegan for her contributions to this overview paper during the past 5 years. Dr. Finnegan will be focusing on other professional endeavors and she will not return as a contributing author.
