Reliability of quantitative sensory testing on myofascial trigger points in the upper trapezius muscle of individuals with chronic neck pain

SUMMARY OBJECTIVE: The objective of this study was to measure the intra- and inter-rater reliability of the quantitative sensory testing for measuring the thermal pain threshold on myofascial trigger points in the upper trapezius muscle of individuals with chronic neck pain. METHODS: Thirty female participants were included, aged between 18 and 45 years and with bilateral myofascial trigger points, active and centrally located in the upper trapezius muscle. Two measurements with quantitative sensory testing were performed by each examiner at an interval of 1 week between them. RESULTS: We observed substantial reliability for the intra-rater analysis (intraclass correlation coefficient ranging between 0.876 and 0.896) and excellent reliability for the inter-rater analysis (intraclass correlation coefficient ranging between 0.917 and 0.954). CONCLUSION: The measurement of the thermal pain threshold on myofascial trigger points in individuals with chronic neck pain has acceptable reliability values, supporting the use of the quantitative sensory testing in the research setting and the clinical environment.

Myofascial component of cancer pain review.

BACKGROUND: Pain is a common complaint of cancer patients, experienced by 38%-85% of patients. Some studies have shown a high incidence of myofascial pain syndrome (MPS) in cancer patients. AIMS: 1) To estimate the prevalence of MPS in cancer patients; 2) to examine the efficacy of current treatment options for MPS in cancer patients. METHODS: Narrative review. PubMed, CINAHL, PEDro, and Google Scholar databases were searched from inception until November 2017, for the keywords: cancer; cancer pain; breast cancer; mastectomy; lumpectomy; myofascial pain; trigger points. Trials of any methodological quality were included. All published material with an emphasis on randomized control trials was analyzed. RESULTS: MPS is prevalent in cancer patients who suffer from pain, with a prevalence of between 11.9% and 44.8% in those diagnosed either with neck or head or breast cancer. Clinical studies showed conflicting results. Four interventional studies found that specific treatment for MPS may reduce the prevalence of active myofascial trigger points and therefore decrease pain level, sensitivity, and improve range of motion (in shoulder) in cancer patients. Two recent randomized control trials showed that pressure release of trigger points provides no additional beneficial effects to a standard physical therapy program for upper limb pain and function after breast cancer surgery. CONCLUSIONS: We recommend including the evaluation of myofascial pain in routine clinical examination of cancer patients suffering from pain. Future studies are needed to investigate the long- and short-term effect of MPS treatments in cancer patients.

Musculoskeletal neck disorders in thyroid cancer patients after thyroidectomy.

Thyroid cancer (TC) is the most common type of cancer in the endocrine system, and thyroidectomy is the preferred treatment. Complications associated are still common and 80% of patients complain of posterior neck pain. The aim of this study was to analyse the long-term musculoskeletal disorders in TC patients who had undergone thyroidectomy. An observational case-control study was carried out. Twenty-eight patients who had undergone thyroidectomy and 28 healthy control patients were included. Outcomes were collected 6 months after surgery and included: musculoskeletal neck disorders (neck range of movement, trigger points) and functional variables (pain intensity and disability). Significant differences were found between groups in flexion (p = 0.002) and extension (p = 0.005), with lower values in the thyroidectomy group. The number of trigger points was higher in the thyroidectomy group in both scalenes (p < 0.001), both sternocleidomastoids (p < 0.001), both upper trapezius (p = 0.005 and p = 0.008), right levator scapulae (p = 0.002) and both suboccipitalis (p = 0.002). Pain intensity (p < 0.001) and the Neck Outcome Scale subscales (p < 0.05) also presented significant differences. Thyroidectomy patients, 6 months after surgery, show a significant decrease in neck range of movement and an increase in the number of trigger points. They also show greater pain intensity and more disability.

Myofascial trigger points in migraine and tension-type headache.

BACKGROUND: A myofascial trigger point is defined as a hyperirritable spot in skeletal muscle that is associated with a hypersensitive palpable nodule in a taut band. It has been suggested that myofascial trigger points take part in chronic pain conditions including primary headache disorders. The aim of this narrative review is to present an overview of the current imaging modalities used for the detection of myofascial trigger points and to review studies of myofascial trigger points in migraine and tension-type headache. FINDINGS: Different modalities have been used to assess myofascial trigger points including ultrasound, microdialysis, electromyography, infrared thermography, and magnetic resonance imaging. Ultrasound is the most promising of these modalities and may be used to identify MTrPs if specific methods are used, but there is no precise description of a gold standard using these techniques, and they have yet to be evaluated in headache patients. Active myofascial trigger points are prevalent in migraine patients. Manual palpation can trigger migraine attacks. All intervention studies aiming at trigger points are positive, but this needs to be further verified in placebo-controlled environments. These findings may imply a causal bottom-up association, but studies of migraine patients with comorbid fibromyalgia syndrome suggest otherwise. Whether myofascial trigger points contribute to an increased migraine burden in terms of frequency and intensity is unclear. Active myofascial trigger points are prevalent in tension-type headache coherent with the hypothesis that peripheral mechanisms are involved in the pathophysiology of this headache disorder. Active myofascial trigger points in pericranial muscles in tension-type headache patients are correlated with generalized lower pain pressure thresholds indicating they may contribute to a central sensitization. However, the number of active myofascial trigger points is higher in adults compared with adolescents regardless of no significant association with headache parameters. This suggests myofascial trigger points are accumulated over time as a consequence of TTH rather than contributing to the pathophysiology. CONCLUSIONS: Myofascial trigger points are prevalent in both migraine and tension-type headache, but the role they play in the pathophysiology of each disorder and to which degree is unclarified. In the future, ultrasound elastography may be an acceptable diagnostic test.

Analysis of chronic myofascial pain in the upper trapezius muscle of breast cancer survivors and women with neck pain.

Myofascial trigger points are present in dysfunctioning muscles and are associated with several diseases. However, the scientific literature has not established whether myofascial trigger points of differing etiologies have the same clinical characteristics. Thus, the objective of the present study was to compare the intensity of myofascial pain, catastrophizing, and the pressure pain threshold at myofascial trigger points among breast cancer survivors and women with neck pain. This was a cross-sectional study that included women over 18 years old complaining of myofascial pain in the upper trapezius muscle region for more than 90 days, equally divided into breast cancer survivors (n = 30) and those with neck pain (n = 30). For inclusion, the presence of a bilateral, active, and centrally located trigger point with mean distance from C7 to acromion in the upper trapezius was mandatory. The measures of assessment were: pain intensity, catastrophizing, and the pressure pain threshold at the myofascial trigger points. A significant difference was observed only when comparing pain intensity (p < 0.001) between the breast cancer survivors (median score: 8.00 points, first quartile: 7.00 points, third quartile: 8.75 points) and women with neck pain (median score: 2.50 points, first quartile: 2.00 points, third quartile: 4.00 points). No significant difference was found between groups in catastrophizing and pressure pain threshold. The conclusion of this study was that breast cancer survivors have a higher intensity of myofascial pain in the upper trapezius muscle when compared to patients with neck pain, which indicates the need for evaluation and a specific intervention for the myofascial dysfunction of these women.

Evidence of Generalized Muscle Stiffness in the Presence of Latent Trigger Points Within Infraspinatus.

OBJECTIVE: To evaluate stiffness of infraspinatus muscle tissue, both with and without latent trigger points, using ultrasound shear wave elastography (SWE). The primary hypothesis is that muscle with a latent trigger point will demonstrate a discrete region of increased shear wave speed. The secondary hypothesis is that shear wave speed (SWS) in the region with the trigger point will be higher in patients compared with controls, and will be similar between the two groups in the uninvolved regions. DESIGN: Case-control. SETTING: Hospital-based outpatient physical therapy center. PARTICIPANTS: Convenience sample (N=18) of patients (6 female, 3 male, mean age=44) (range=31-61y) diagnosed with latent trigger points in infraspinatus and matched controls without trigger points. MAIN OUTCOME MEASURES: Shear wave speed (m/s). RESULTS: SWS of the latent trigger point (mean=4.09±SD1.4 m/s) did not differ from the adjacent muscle tissue (3.92±1.6 m/s, P>.05), but was elevated compared to corresponding tissue in controls (2.8±0.75 m/s, P=.02). SWS was generally greater in patients' uninvolved tissue (3.83±1.6 m/s) when compared to corresponding tissue in controls (2.62±0.2 m/s, P=.05). CONCLUSION: Although discrete regions of increased SWS corresponding to the trigger point were not observed in patients, evidence of generally increased muscle stiffness in infraspinatus was exhibited compared to healthy controls. Further study of additional muscles with SWE is warranted.

A critical overview of the current myofascial pain literature - January 2018.

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.

Ischemic compression and kinesiotherapy on chronic myofascial pain in breast cancer survivors.

OBJECTIVE: assess the effects of ischemic compression and kinesiotherapy on the rehabilitation of breast cancer survivors with chronic myofascial pain. METHODS: A randomized, controlled, blinded clinical trial was performed with 20 breast cancer survivors with myofascial trigger point in the upper trapezius muscle. Patients were randomly allocated to ischemic compression + kinesiotherapy (G1, n = 10) and kinesiotherapy (G2, n = 10). Both groups were submitted to 10 sessions of treatment. The variables evaluated were: Numeric Rating Scale, Pain Related Self-Statement Scale, pressure pain threshold, Functional Assessment of Cancer Therapy-Breast and Infrared thermography. RESULTS: A significant reduction (p < 0.05) was observed in pain intensity after 10 sessions in Groups 1 and 2, a significant increase (p < 0.05) in pressure pain threshold in both the operated and non-operated side after 10 sessions for Group 1. CONCLUSION: Ischemic compression associated with kinesiotherapy increases the pressure pain threshold on the myofascial trigger point in the upper trapezius muscle and reduces the intensity of pain in breast cancer survivors with myofascial pain.

Central Sensitization Is Modulated Following Trigger Point Anesthetization in Patients with Chronic Pain from Whiplash Trauma. A Double-Blind, Placebo-Controlled, Crossover Study.

Objective: Central sensitization (CS) with low peripheral pain thresholds (PPTs) is a common finding among patients with chronic pain after whiplash (CPWI). While it has been proposed that myofascial myofascial trigger points (MTrPs) may act as modulators of central sensitization, previously reported findings are conflicting and inconclusive. The present study was designed to investigate immediate responsiveness of CS to alterations in nociceptive input. Design: Controlled, double-blind, cross-over. Subjects: Thirty-one patients with chronic pain (trapezius myalgia) and CS after whiplash. Methods: Participants were referred by randomization to group A for injection of a single peripheral pain generator (MTrP or other discrete tender point) with local anesthetic or to group B for sham injection and cross-over. Documentation of PPT (Algometer), maximum jaw opening (caliper), and grip strength (Vigorimeter), as well as subjective overall pain (visual analog scale [VAS]), was made before and after each intervention. Results: Statistical analysis of data (Student's t test, analysis of variance) confirmed that peripheral pain thresholds were significantly higher and maximum jaw opening significantly greater after anesthetizing a focal pain generator in the trapezius, but not after a sham injection. In contrast with the objective variables, subjective generalized pain improved (VAS) after not only an injection of local anesthetic, but also, and to a similar extent, after a sham injection. Conclusions: CS, as expressed by lowered PPT, is a rapidly adjusting physiological response to nociceptive stimuli in some patients with chronic pain after whiplash. PPT are likely modulated by myofascial tender points in selected patients with CS. With reference to the present findings, surgical ablation of MTrPs is discussed as a potential treatment modality for CS.

Myofascial trigger points in patients with temporomandibular joint disc displacement with reduction: a cross-sectional study

Abstract Objective The objective of this retrospective study was to evaluate the impact of myofascial trigger points (MTrPs) in patients with articular disc displacement with reduction (DDWR) and to identify which clinical variables are associated with the concomitant presence of DDWR and MTrPs. Material and Methods 130 patients were selected that sought treatment due to joint pain, with ages ≥18 years, of both genders, with DDWR confirmed by magnetic resonance imaging. The sample was divided into two groups: Group 1, patients with DDWR and MTrPs (N=101); and Group 2, patients with DDWR and no MTrPs (N=29). Information on gender, age, pain duration, pain scores, and maximal interincisal distance (MID) were collected. The logistic regression model was used and the odds ratios (OR) was calculated (p<0.05). Results Group 1 presented statistically significant higher mean pain scores (p=0.007), and smaller MID (p=0.0268) than Group 2. OR were significant for the pain scores (1.429), MID (0.937) and gender (women) (2.810). Conclusions Patients with DDWR and MTrPs had increased pain scores and a MID decrease compared to patients with DDWR and no MTrPs. The variables pain scores, MID, and gender (women) showed a significant association with the concomitant presence of DDWR and MTrPs.

Histopathological nature of myofascial trigger points at different stages of recovery from injury in a rat model.

OBJECTIVE: To investigate the histopathological nature of myofascial trigger points (MTrPs) or spots (MTrSs) at different stages of recovery from injury in a rat model. METHODS: Forty Sprague-Dawley rats were randomly divided into two groups: a control group (CG) and experimental group (EG). The CG was further randomly subdivided into CG1 and CG2 subgroups. The CG2 was used for palpating the taut band and CG1 as a blank. EG was subdivided into three groups according to recovery times: 4 weeks (4W), 8 weeks (8W) and 12 weeks (12W); these groups consisted of eight rats each. All CG rats received no intervention, whereas the intervention in EG rats was by a blunt strike to the vastus medialis and eccentric exercise for 8 weeks. The taut bands with spontaneous electrical activity were then detected in the muscle to guide a muscle biopsy. The histopathological findings were investigated under optical and electron microscopes in all groups. RESULTS: Under optical microscopy, the differently augmented sizes of round fibres (contracture knots) with deep staining in the transverse section and fusiform shapes in a longitudinal view were clearly seen in CG2 and EGs with a large diameter; the number of contracture knots was significantly more in EGs than in CGs. Under an electron microscope, the mitochondria in EGs significantly decreased with abnormal structures. The sarcomeres were significantly shortened in the 8W and 12W EGs. CONCLUSION: An injury can cause activation of MTrSs in a muscle and an activated level of MTrPs depending on the number of contracture knots in muscle with impaired energy production.

Quantification of dry needling on myofascial trigger points using a novel ultrasound method: A study protocol.

INTRODUCTION: Myofascial pain syndrome (MPS) is a neuromuscular dysfunction consisting of both motor and sensory abnormalities. Considering the high prevalence of MPS and its related disabilities and costs, this study was designed to determine the reliability of new ultrasonographic indexes of the upper trapezius muscle as well as the sensitivity and specificity of 2D ultrasound imaging for diagnostic purposes. Furthermore, we sought to evaluate the effectiveness of dry needling (DN) on studied ultrasonographic indexes. MATERIALS AND METHODS: This study will be performed in two steps with two different designs. The first is a pilot study and was designed as a semi-experimental study to determine the sensitivity and specificity of ultrasonography for the diagnosis of MPS and the reliability of ultrasonographic measurements like muscle thickness, area of myofascial trigger points (MTrPs) in longitudinal view, echogenicity of MTrPs in longitudinal view, echogenicity of muscle with MTrPs in longitudinal and transverse views, and pennation angle of upper trapezius muscle. The second study is an interventional study which was designed to investigate the effectiveness of DN on ultrasonographic measurements, for which the reliability was determined in the first study. CONCLUSION: we will quantify the effectiveness of DN on MTrPs and muscle tissue by using novel ultrasonographic indexes. The results of the current study will provide baseline information to design more interventional studies to improve the evaluation of other treatments of MPS.

Myofascial pain and fibromyalgia: two different but overlapping disorders.

There is good evidence supporting that people with fibromyalgia syndrome (FMS) exhibit central sensitization. The role of peripheral nociception is under debate in FMS. It seems that widespread pain experienced in FMS is considered multiple regional pains; therefore, several authors proposed that muscles play a relevant role in FMS. Trigger points (TrPs) have long been a contentious issue in relation to FMS. Preliminary evidence reported that the overall spontaneous pain is reproduced by referred pain from active TrPs, suggesting that FMS pain is largely composed of pain arising, at least partially, from TrPs. Finally, there is preliminary evidence suggesting that management of TrPs is able to modulate the CNS and is effective for reducing pain in FMS, although results are conflicting and future studies are clearly needed.

Muscle Trigger Points and Pressure Pain Sensitivity Maps of the Feet in Women with Fibromyalgia Syndrome.

OBJECTIVE : To investigate the presence of trigger points (TrPs) in feet musculature and topographical pressure sensitivity maps of the feet as well as the relationship between TrPs, pressure pain maps, and clinical variables in women with fibromyalgia (FMS). METHODS : Fifty-one FMS women and 24 comparable healthy women participated. TrPs within the flexor hallucis brevis, adductor hallucis, dorsal interossei, extensor digitorum brevis, and quadratus plantae, as well as external and internal gastrocnemius, were explored. Pressure pain thresholds (PPTs) were assessed in a blind manner over seven locations on each foot. Topographical pressure sensitivity maps of the plantar region were generated using the averaged PPT of each location. RESULTS : The prevalence rate of foot pain was 63% (n = 32). The number of active TrPs for each FMS woman with foot pain was 5 ± 1.5 without any latent TrPs. Women with FMS without foot pain and healthy controls had only latent TrPs (2.2 ± 0.8 and 1.5 ± 1.3, respectively). Active TrPs in the flexor hallucis brevis and adductor hallucis muscles were the most prevalent. Topographical pressure pain sensitivity maps revealed that FMS women with foot pain had lower PPT than FMS women without pain and healthy controls, and higher PPT on the calcaneus bone (P < 0.001). CONCLUSIONS : The presence of foot pain in women with FMS is high. The referred pain elicited by active TrPs in the foot muscles reproduced the symptoms in these patients. FMS women suffering foot pain showed higher pressure hypersensitivity in the plantar region than those FMS women without pain.

Latent Trigger Points: What Are the Underlying Predictors?

OBJECTIVE: To determine the factors predicting the presence and number of latent trigger points (LTrPs) in healthy individuals. DESIGN: Cross-sectional study. SETTING: Local faculty of health sciences. PARTICIPANTS: Healthy individuals (N=242) were divided into 2 groups: group 1, those without LTrPs (n=68); and group 2, those with LTrPs (n=174). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Disability was assessed using the Quick-Disabilities of the Arm, Shoulder, and Hand questionnaire and the Neck Pain and Disability Scale. Psychological factors were evaluated using the Brief Symptom Inventory, the Beck Depression Inventory, the State-Trait Anxiety Inventory, and the Perceived Stress Scale. Quality of life was evaluated using the Short-Form-12; smoking habits were determined with questions about current smoking status; and pain level was assessed using the visual analog scale. The LTrP assessment was made with a pinching movement or flat palpation bilaterally. RESULTS: By using a hierarchical regression model, we entered age, depression, and pain level into the first block, which explained a significant amount of variance in the presence and number of LTrPs (R(2)=.041; P=.033 and R(2)=.197; P<.001, respectively). Pain level contributed independently the presence of LTrPs, whereas age and pain level predicted the number of LTrPs (P<.05). CONCLUSIONS: This study found that pain and age were significant predictors of the number of LTrPs, but only pain predicted the presence of LTrPs in healthy individuals.

A critical overview of the current myofascial pain literature - October 2015.

The number of publications about myofascial pain and trigger points (TrP) seems to increase every year. In the current overview we include 27 articles published in past months. The Basic Review section includes articles about the presence and characteristics of TrPs in various neck and shoulder muscles, the correlation between referred pain from active TrPs and knee osteoarthritis, and an anatomical study exploring whether the location of TrPs may be related to the nerve innervation of muscles. Zuil-Escobar and colleagues from Spain considered the intra-rater reliability of the identification of latent TrPs in several leg muscles and the possible correlation of TrP and the presence of a lower medial longitudinal arch. In the section on manual approaches, contributing author Rob Grieve and colleagues continue their studies of TrPs in the lower extremity muscles, while Méndez-Rebolledo and colleagues studied the impact of cross taping and compression. Dry needling (DN) continues to be a topic of interest. We included twelve papers addressing a wide range of topics, such as the effectiveness and safety of DN, and the impact of DN on proprioception, spasticity, and fibromyalgia. Two papers investigated the utilization of repetitive transcranial magnetic stimulation and laser on TrPs, The final section on other clinical studies and reviews includes 8 papers. The studies originated in thirteen different countries with Spain leading the charts with 7 contributions to the literature, followed by Brazil with four. As we have mentioned in previous editions of this literature overview, many studies suffer from very small sample sizes, which makes it difficult to reach definitive conclusions. Nevertheless, myofascial pain continues to be a topic of interest to researchers and clinicians around the globe.

The Current Means for Detection of Migraine Headache Trigger Sites.

The authors' 15-year experience with migraine surgery has led them to believe that the most common reasons for incomplete response are failure to detect all of the trigger sites or, on rare occasions, inadequate surgery on the trigger sites. Thus, accurate identification of trigger sites is essential. The purpose of this article is to share the authors' current stepwise algorithm for accurately detecting the migraine trigger sites, which has evolved through surgery on nearly 1000 patients. To begin, a thorough history is taken. Each patient's constellation of symptoms can point toward one or multiple trigger points. The patient is asked to point to the most frequent site from which migraine headaches originate with one fingertip, and then the site is explored with a Doppler. If an arterial Doppler signal is identified at the site, it is considered an active arterial trigger site. Response to a nerve block with a local anesthetic in a patient with an active migraine headache confirms the presence of a trigger site. If the patient does not have pain at the time of the office visit, an injection of botulinum toxin A at the suspected trigger site may be considered. Although positive responses to botulinum toxin A and nerve block are very helpful and reliable in confirming the trigger sites, negative responses must be interpreted with extreme caution. In patients with a migraine headache starting from the retrobulbar site, a computed tomography scan of the paranasal sinuses is obtained to look for contact points and other pathology that would confirm rhinogenic trigger sites.

Predicting outcomes of neuroreflexotherapy in patients with subacute or chronic neck or low back pain.

BACKGROUND CONTEXT: In the context of shared decision-making, a valid estimation of the probability that a given patient will improve after a specific treatment is valuable. PURPOSE: To develop models that predict the improvement of spinal pain, referred pain, and disability in patients with subacute or chronic neck or low back pain undergoing a conservative treatment. STUDY DESIGN AND SETTING: Analysis of data from a prospective registry in routine practice. PATIENT SAMPLE: All patients who had been discharged after receiving a conservative treatment within the Spanish National Health Service (SNHS) (n=8,778). OUTCOME MEASURES: Spinal pain, referred pain, and disability were assessed before the conservative treatment and at discharge by the use of previously validated methods. METHODS: Improvement in spinal pain, referred pain, and disability was defined as a reduction in score greater than the minimal clinically important change. A predictive model that included demographic, clinical, and work-related variables was developed for each outcome using multivariate logistic regression. Missing data were addressed using multiple imputation. Discrimination and calibration were assessed for each model. The models were validated by bootstrap, and nomograms were developed. RESULTS: The following variables showed a predictive value in the three models: baseline scores for pain and disability, pain duration, having undergone X-ray, having undergone spine surgery, and receiving financial assistance for neck or low back pain. Discrimination of the three models ranged from slight to moderate, and calibration was good. CONCLUSIONS: A registry in routine practice can be used to develop models that estimate the probability of improvement for each individual patient undergoing a specific form of treatment. Generalizing this approach to other treatments can be valuable for shared decision making.

Sono-myography and sono-myoelastography of the tender points of women with fibromyalgia.

Sono-myography and sono-myoelastography have been found useful in the investigation of myofascial trigger points. The objective of this study was to use the same techniques to investigate the morphology, stiffness and blood flow of tender points in women with fibromyalgia and to compare the results with those for samples from healthy patients. Algometry tests indicated significant differences between groups (p < 0.001). Elliptical and hypoechoic areas were observed in the ultrasound images of the upper trapezius in both groups. No differences between groups were found in the number of hypoechoic areas (p = 0.167, t = 1.008); blood flow also did not differ between the groups. Larger hypoechoic areas were found in the fibromyalgia group (p = 0.139, t = 1.317). Sono-myoelastography did not reveal greater stiffness in these areas compared with the rest of the muscle. These results lead us to believe that sono-myoelastography and sono-myography, used in the diagnosis of myofascial trigger points, may not be able to discriminate tender points.

Complementary treatment in fibromyalgia: combination of somatic and abdominal acupuncture.

Fibromyalgia is a complex syndrome characterised by widespread pain associated with a variety of other signs and symptoms. The emerging consensus indicates that the best approach to treatment involves the combination of pharmacological and non-pharmacological interventions. Since acupuncture is a tool of traditional Chinese medicine increasingly used as an alternative or complementary therapy for the treatment of pain, the present study aimed to combine two different acupunctural methods (the somatic and abdominal one) in the treatment of 30 consecutive female FM patients and to evaluate the reduction of pain and the well-being state. The results showed a statistically significant reduction of the number of tender points and of pain. Moreover we observed a statistically significant reduction of FIQ, FAS, HAQ, disease activity VAS, ZSAS, ZSDS at the end of the treatment. In conclusion, these data suggest that the combination of two types of acupuncture could be a useful complementary treatment in FM patients, not only to control pain but also to improve associated symptoms and quality of life. As a result, acupuncture could be very useful to relieve pain in a multidisciplinary setting.
