Influence of quantified dry cupping on soft tissue compliance in athletes with myofascial pain syndrome.

PURPOSE: This study aimed to develop a quantitative dry cupping system that can monitor negative pressure attenuation and soft tissue pull-up during cupping to quantify soft tissue compliance. METHODS: Baseball players with myofascial pain syndrome were recruited to validate the benefits of cupping therapy. Nine of 40 baseball players on the same team were diagnosed with trapezius myofascial pain syndrome; another nine players from the same team were recruited as controls. All participants received cupping with a negative pressure of 400 mmHg for 15 minutes each time, twice a week, for 4 weeks. Subjective perception was investigated using upper extremity function questionnaires, and soft tissue compliance was quantified objectively by the system. RESULTS: During the 15-minute cupping procedure, pressure attenuation in the normal group was significantly greater than that in the myofascial group (p = 0.017). The soft tissue compliance in the normal group was significantly higher than that in the myofascial group (p = 0.050). Moreover, a 4-week cupping intervention resulted in an obvious increase in soft tissue lift in the myofascial pain group (p = 0.027), although there was no statistical difference in the improvement of soft tissue compliance. Shoulder (p = 0.023) and upper extremity function (p = 0.008) were significantly improved in both groups, but there was no significant difference between the two groups. CONCLUSION: This quantitative cupping monitoring system could immediately assess tissue compliance and facilitate the improvement of soft tissues after cupping therapy. Hence, it can be used in athletes to improve their functional recovery and maintain soft tissues health during the off-season period.

Treatment and management of myofascial pain syndrome.

Myofascial Pain Syndrome (MPS) is a regional pain disorder that affects every age-group and is characterized by the presence of trigger points (TrPs) within muscles or fascia. MPS is typically diagnosed via physical exam, and the general agreement for diagnostic criteria includes the presence of TrPs, pain upon palpation, a referred pain pattern, and a local twitch response. The prevalence of MPS among patients presenting to medical clinics due to pain ranges anywhere from 30 to 93%. This may be due to the lack of clear criteria and guidelines in diagnosing MPS. Despite the prevalence of MPS, its pathophysiology remains incompletely understood. There are many different ways to manage and treat MPS. Some include exercise, TrP injections, medications, and other alternative therapies. More research is needed to form uniformly-accepted diagnostic criteria and treatments.

Ashi Acupuncture Versus Local Anesthetic Trigger Point Injections in the Treatment of Abdominal Myofascial Pain Syndrome: A Randomized Clinical Trial.

BACKGROUND: Chronic pelvic pain (CPP) is defined as recurrent or continuous pain in the lower abdomen or pelvis, non-menstrual or non-cyclic, lasting at least 6 months. There is strong evidence that up to 85% of patients with CPP have serious dysfunction of the musculoskeletal system, including abdominal myofascial syndrome (AMPS). AMPS is characterized as deep abdominal pain, originating from hyperirritable trigger points, usually located within a musculoskeletal range or its fascia of coating. In the literature, there are few studies that address AMPS. OBJECTIVE: This study aimed to compare the responses of ashi acupuncture treatment and local anesthetic injection in the treatment of chronic pelvic pain secondary to abdominal myofascial pain syndrome in women. STUDY DESIGN: Randomized controlled clinical trial. SETTING: Tertiary University Hospital. METHODS: Women with a clinical diagnosis of CPP secondary to AMPS were randomized and evaluated using instruments to assess clinical pain, namely, the visual analogue scale (VAS), numerical categorial scale (NCS), and the McGill Questionnaire, after receiving treatment with ashi acupuncture (group A, n = 16) or local anesthetic injections (group B, n = 19). They were reevaluated after one week and one, 3, and 6 months after each treatment, in addition to assessments of pain and adverse events performed during the sessions. RESULTS: Ashi acupuncture and local anesthetic injections were both effective in reducing clinical pain assessed through the analyzed variables among study participants. There was no difference between the groups and there was a strong correlation between these pain assessment instruments. LIMITATIONS: The absence of blinding to the different forms of treatment among the patients and the researcher directly involved in the treatment, the absence of a placebo group, the selective exclusion of women with comorbidities and other causes of CPP, and the difference between the number of sessions used for each technique. CONCLUSION: Treatments with ashi acupuncture and local anesthetic injections were effective in reducing clinical pain in women with abdominal myofascial pain syndrome.

Interrater and Intrarater Reliability and Minimum Detectable Change of Ultrasound for Active Myofascial Trigger Points in Upper Trapezius Muscle in Individuals With Shoulder Pain.

OBJECTIVE: We sought to investigate the interrater and intrarater reliability of ultrasound and the minimum detectable change (MDC) for the trigger points (TrPs) active in the upper trapezius (UT) muscle in individuals with shoulder pain. METHODS: Forty individuals with shoulder pain were investigated for the presence of active TrPs in the UT muscle by means of ultrasound for the parameters of gray scale, muscle thickness of UT muscle at rest, and contraction and area of TrPs. The intrarater reliability was performed on 2 days, and interrater reliability on the same day. For the gray scale, the reliability was evaluated using the kappa coefficient (κ), while the other parameters were measured by the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and MDC. RESULTS: For the gray scale, the intrarater agreement was almost perfect (κ = 1.00) and the interrater agreement was substantial (κ = 0.75). The intrarater and interrater reliability were excellent for most of the parameters, except for the area of TrPs (intrarater: ICC = 0.71, substantial; interrater: ICC = 0.52, substantial). The MDC for intrarater reliability varied between 0.04 and 0.05 (SEM% between 2.4% and 38.87%), and that for interrater reliability ranged from 0.05 to 0.07 (SEM% between 3.18% and 55.10%), with a higher value for area. CONCLUSION: Parameters such as gray scale, resting muscle thickness, and muscle contraction of the UT muscle, obtained through ultrasound, showed excellent intrarater and interrater reliability with low SEM%. The intrarater and interrater reliability for the area deserves a caveat regarding their use.

Can the Positional Release Technique Affect Central Sensitization in Patients With Chronic Tension-Type Headache? A Randomized Clinical Trial.

OBJECTIVES: To investigate whether the positional release technique (PRT) affects central sensitization in patients with chronic tension-type headache (TTH). DESIGN: Randomized controlled trial with concealed allocation, assessor blinding, and intention-to-treat analysis. SETTING: Two university neurology clinics. PARTICIPANTS: Patients (N=32) with TTH and myofascial trigger points (MTrP) in their cervical muscles. INTERVENTIONS: Patients in the PRT group received 10 treatment sessions for each of their MTrPs over the course of 5 weeks. All participants could use ibuprofen 200 mg for their headaches during the study. MAIN OUTCOME MEASURES: The primary outcome measure was brain metabolite profile. The secondary outcome measures were headache frequency and intensity, McGill score, and pressure pain threshold (PPT), which were evaluated in each participant during 5 weeks with proton magnetic resonance spectroscopy, patients' self-reports, the McGill Pain Questionnaire, and a pressure algometer. RESULTS: Analysis of the data from 26 patients showed that headache frequency (P=.001), headache intensity (P=.002), McGill score (P=.003), and local PPT (P=.003) changed significantly after PRT. The myo-inositol/creatine concentration ratio in the somatosensory cortex (P=.041) decreased significantly in the control group. Furthermore, there were significant differences between groups in headache frequency (P<.001), headache intensity (P<.001), McGill score (P<.001), local PPT (P=.004), distal PPT (P=.041), and glutamate-glutamine/creatine concentration ratio in the thalamus (P=.014). CONCLUSIONS: These findings indicate that PRT did not affect central sensitization in patients with TTH despite the improvement in clinical symptoms.

The effects of dry needling on pain relief and functional balance in patients with sub-chronic low back pain.

BACKGROUND: Pain relief is important both for the movement of patients suffering from low back pain and the quality of life. Dry needling is effective on myofascial trigger points but its effect on the area of pain and the functional balance is not fully known. OBJECTIVE: To examine the immediate effect of dry needling on pain and functional balance of patients suffering from low back pain. METHODS: Twenty five patients with sub-chronic low back pain were randomly divided into two groups: the intervention or control group. Needles were used for the participants of the intervention group, bilaterally at the spinus level, one and a half finger breath from the midline in levels L2-L5 of the lumbar spine. A third line of needles was inserted in the interspinosus spaces, except L5-S1 level. Bipedal stance, lateral loading and mediolateral body sway were assessed using a pair of force plates. Pain tolerance was assessed using an algometer. RESULTS: The pain tolerance significantly increased in the intervention group from (M = 4.87, SE 0.663) to (M = 6.52, SE 0.547) (F(1,23) = 7.8, p< 0.05) after intervention. During mediolateral body sway the force signal in the dominant frequency significantly increased in the intervention group from (M = 43.2, SE 4.6) to (M = 54,9, SE 3.6) (F(1,23) = 4.63, p< 0.05) after intervention, exhibiting more controlled rhythmic behavior. CONCLUSIONS: Dry needling in painful areas and penetrating all the muscle groups seems to improve pain and functional balance, yet its effect on specific muscles needs to be studied further.

Effects of dry needling of active trigger points in the scalene muscles in individuals with mechanical neck pain: a randomized clinical trial.

OBJECTIVE: The aim of this study was to compare the effects of dry needling (DN) versus pressure release over scalene muscle trigger points (TrPs) on pain, related disability, and inspiratory vital capacity in individuals with neck pain. METHODS: In this randomized, single-blind trial, 30 patients with mechanical neck pain and active TrPs in the scalene musculature were randomly allocated to trigger point dry needling (TrP-DN; n = 15) or pressure release (n = 15) groups. The DN group received a single session of DN of active TrPs in the anterior scalene muscles, and the pressure release group received a single session of TrP pressure release over the same muscle lasting 30 s. The primary outcome was pain intensity as assessed by a numerical pain rate scale (NPRS, 0-10). Secondary outcomes included disability (neck disability index, NDI) and inspiratory vital capacity. Outcomes were assessed at baseline and 1 day (immediately post), 1 week, and 1 month after the treatment session. Data were expressed as mean score difference (Δ) and standardized mean difference (SMD). RESULTS: Patients receiving DN exhibited a greater decrease in pain intensity than those receiving TrP pressure release at 1 month (Δ 1.2 (95% CI-1.8, -0.6), p = 0.01), but not immediately (1 day) or 1 week after. Patients in the DN group exhibited a greater increase in inspiratory vital capacity at all follow-up time points (Δ 281 mm (95% CI 130, 432) immediately after, Δ 358 mm (95% CI 227, 489) 1 week after, and Δ 310 mm (95% CI 180, 440) 1 month after treatment) than those in the pressure release group (p = 0.006). Between-group effect sizes were large at all follow-up time points (1.1 > SMD > 1.3) in favor of DN. CONCLUSION: This trial suggests that a single session of DN over active TrPs in the scalene muscles could be effective at reducing pain and increasing inspiratory vital capacity in individuals with mechanical neck pain. Future studies are needed to further confirm these results.

Alleviation of migraine symptoms by application of repetitive peripheral magnetic stimulation to myofascial trigger points of neck and shoulder muscles - A randomized trial.

Migraine is a burdensome disease with an especially high prevalence in women between the age of 15 and 49 years. Non-pharmacological, non-invasive therapeutic methods to control symptoms are increasingly in demand to complement a multimodal intervention approach in migraine. Thirty-seven subjects (age: 25.0 ± 4.1 years; 36 females) diagnosed with high-frequency episodic migraine who presented at least one active myofascial trigger point (mTrP) in the trapezius muscles and at least one latent mTrP in the deltoid muscles bilaterally prospectively underwent six sessions of repetitive peripheral magnetic stimulation (rPMS) over two weeks. Patients were randomly assigned to receive rPMS applied to the mTrPs of the trapezius (n = 19) or deltoid muscles (n = 18). Whereas the trapezius muscle is supposed to be part of the trigemino-cervical complex (TCC) and, thus, involved in the pathophysiology of migraine, the deltoid muscle was not expected to interfere with the TCC and was therefore chosen as a control stimulation site. The headache calendar of the German Migraine and Headache Society (DMKG) as well as the Migraine Disability Assessment (MIDAS) questionnaire were used to evaluate stimulation-related effects. Frequency of headache days decreased significantly in both the trapezius and the deltoid group after six sessions of rPMS (trapezius group: p = 0.005; deltoid group: p = 0.003). The MIDAS score decreased significantly from 29 to 13 points (p = 0.0004) in the trapezius and from 31 to 15 points (p = 0.002) in the deltoid group. Thus, rPMS applied to mTrPs of neck and shoulder muscles offers a promising approach to alleviate headache frequency and symptom burden. Future clinical trials are needed to examine more profoundly these effects, preferably using a sham-controlled setting.

Comparison of Three Manual Therapy Techniques as Trigger Point Therapy for Chronic Nonspecific Low Back Pain: A Randomized Controlled Pilot Trial.

Objectives: This pilot study aimed to compare the efficacy of manual pressure release (MPR), strain counterstrain (SCS), and integrated neuromuscular inhibition technique (INIT) in the management of chronic nonspecific low back pain (LBP). Design: Single-blind, randomized, controlled pilot trial. Setting: Neurosurgery clinic. Subjects: Forty-eight patients (46 women; mean age, 35.47 ± 10.58 years) diagnosed chronic nonspecific LBP and who had at least one active myofascial trigger point (MTrP) in the quadratus lumborum, iliocostalis lumborum, gluteus maximus, gluteus medius, and gluteus minimus muscles were included. Interventions: Patients received a standard home exercise program in addition to the MPR technique (MPR group), SCS technique (SCS group), and INIT (INIT group) for 12 sessions (2 days/week for 6 weeks). Outcome measures: The primary outcome was the visual analog scale (VAS). The secondary outcomes were MTrP examination, pressure pain threshold, lumbar active range of motion, Oswestry Disability Index (ODI), Beck depression inventory, and state-trait anxiety inventory. Results: There is no significant difference in terms of the percentage of deactivated MTrPs after 1st session and 12th session between groups (p > 0.05), but the percentage of deactivated MTrPs was less in MPR group than other groups. The overall group-by-time interaction for the repeated measures analysis of variance was not significant for primary and secondary outcomes (p > 0.05), but the improvement in the VAS-activity and the ODI was slightly better in the SCS group compared with other groups. Conclusions: These preliminary findings, which might help provide a glimpse into the clinical effectiveness of three manual therapy techniques (MPR, SCS, and INIT) rather than statistical significance, indicated that SCS or INIT might provide slightly better improvement in pain during activity, deactivation of MTrPs, and disability related to pain in chronic nonspecific LBP.

Relationship between muscle spindles and myofascial trigger spots according to Hoffmann reflex pathway and tissue morphology characteristics in a rat model.

OBJECTIVES: To determine how muscle spindles are involved in the pathophysiology of chronic myofascial trigger spots (MTrSs, similar to myofascial trigger points) in a rat injury model according to the characteristics of the Hoffmann reflex (H-reflex) and the anatomical relationship between muscle spindles and MTrSs. METHODS: 16 male Sprague-Dawley rats (7 weeks old) were randomly divided into experimental and control groups. A blunt strike injury and eccentric exercise were applied to the gastrocnemius muscle of rats in the experimental group once a week for 8 weeks as a MTrS modelling intervention. Subsequently, the rats were reared normally and rested for 4 weeks. At the end of the 12th week, the rats were examined for the presence of MTrSs defined by the detection of a palpable taut band exhibiting both a local twitch response and spontaneous electrical activity. After modelling, evocation of the H-reflex and morphological examination of muscle spindles and MTrSs were conducted. RESULTS: The threshold (0.35±0.04 mA) of the H-reflex and latency (1.24±0.18 ms) of the M wave recorded at MTrSs were not significantly different to those at non-MTrSs (P>0.05). Compared with non-MTrSs, a lower Mmax (4.28±1.27 mV), higher Hmax (median (IQR) 0.95 (0.80-1.08) mV) and Hmax/Mmax (median (IQR) 0.21 (0.16-0.40)), and shorter H wave latency (4.60±0.89 ms) were recorded at MTrSs (P<0.05). Morphologically, there was a close anatomical relationship between the MTrS cells and the muscle spindles. DISCUSSION: Compared with normal muscles, the H-reflex myoelectrical activity was enhanced and some muscle spindles might have been influenced by active MTrSs. Thus, muscle spindles may play an important role in the pathological mechanism underlying myofascial trigger points.

Prevalence and sensitivity of trigger points in lumbo-pelvic-hip muscles in patients with patellofemoral pain syndrome.

OBJECTIVES: Changes in the activity of the lumbo-pelvic-hip muscles have been established as a major cause of patellofemoral pain syndrome (PFPS), a common orthopedic problem. The present study aimed to compare the prevalence and sensitivity of myofascial trigger points (MTrPs) in lumbo-pelvic-hip muscles in persons with and without PFPS. METHODS: Thirty women with PFPS and 30 healthy women 18-40 years old were recruited for this study. The prevalence of MTrPs was assessed by palpation, and pressure algometry was used to measure the pressure pain threshold. This study evaluated the areas where MTrPs are most commonly found in the lumbar muscles (internal oblique, erector spinae and quadratus lumborum), pelvic muscles (gluteus maximus, gluteus medius, gluteus minimus and piriformis), and hip muscles (hip adductor, quadriceps, hamstring, tensor fascia lata and sartorius). Independent t-tests were used to compare mean pressure pain thresholds between the two groups. Chi-squared tests were used to compare the prevalence of MTrPs. RESULTS: The prevalence of MTrPs was significantly higher in most of the lumbo-pelvic-hip muscles in patients with PFPS compared to healthy persons. However, there were no significant differences between groups in the prevalence of MTrPs in the gluteus minimus or adductor muscles. The pressure pain threshold in lumbo-pelvic-hip muscles was lower in patients with PFPS compared to healthy participants. CONCLUSION: In patients with PFPS the prevalence of MTrPs in the lumbo-pelvic-hip region was higher, and the pressure pain threshold was lower, than in healthy people. Thus therapy to treat PFPS should target the lumbo-pelvic-hip muscles.

The prevalence of myofascial trigger points in hip and thigh areas in anterior knee pain patients.

BACKGROUND: Anterior knee pain (AKP) is a widespread problem among young athletes and soldiers. There are many theories on the etiology of AKP but there is little reference to myofascial trigger points (MTrPs) as a possible contributor. AIM: To evaluate the association between AKP and prevalence of active and latent MTrPs in the hip and thigh muscles in soldiers. METHODS: A cross-sectional study was conducted in the Beer-Sheva military outpatient physical therapy clinic. Subjects were 42 men and 23 women referred for physical therapy, 33 with a diagnosis of AKP (cases) and 32 with upper limb complaints (without AKP, controls). All subjects underwent physical evaluation by an examiner blinded to their identity and medical condition. The following muscles were assessed bilaterally for active or latent MTrPs: rectus femoris (proximal), vastus medialis (middle and distal), vastus lateralis (middle and distal) and gluteus medius (anterior, posterior and distal). RESULTS: In six out of eight areas, the cases had a higher prevalence of total active and latent MTrPs than the controls. When summarizing MTrPs by muscle, cases had significantly more MTrPs than controls in each muscle. The largest difference was found in vastus medialis and vastus lateralis; nearly half of the cases had MTrPs in these muscles. CONCLUSIONS: Subjects with AKP have a greater prevalence of MTrPs in their hip and thigh muscles than controls, indicating an association between MTrPs and AKP. Further research is necessary to determine whether MTrPs are the cause or the consequence of AKP.

Local heating of trigger points reduces neck and plantar fascia pain.

BACKGROUND: Heating the skin and muscles is a commonly accepted method of pain relief and a modality to increase relaxation in muscles and increase tissue blood flow. OBJECTIVE: The purpose of the present study was to examine the effect of local heat applied to trigger points and to determine if there was pain relief in the neck and plantar fascia. METHODS: Forty adults were divided into 2 different groups according to their pain; twenty subjects had plantar foot pain and the other 20 had nonspecific neck pain. The 20 subjects in each group were randomly subdivided into a heat and a sham group. Sensitivity to pressure was measured with an algometer. A stopwatch was given to the subject and started when either the heat patch or placebo was applied. Heat cells were applied at trigger points on the pain area. RESULTS: Subjective pain significantly decreased in both sham and heat group patients with neck pain (p< 0.05), however, the change was greater in the heat group and there was a significant difference between the heat and sham groups (p= 0.002, d= 0.81). For the plantar pain group, a significant decrease in subjective pain was found in the heat group but not in the sham group. Pressure pain threshold significantly decreased in the heat group patients both with neck and plantar pain but for the sham group there was an increase in the pressure after sham treatment. Pain relief during the intervention was also significantly different between the heat and sham group in both patients with neck and plantar pain. CONCLUSION: The effect of local heat on trigger points of the body on pain relief was significantly better in the heat groups than in the sham groups. This finding is significant because using heat on trigger points could be an alternative to dry needling performed by healthcare professionals. This modality can be alternative for home use and avoids opioids.

The prevalence of primary dysmenorrhea among students and its association with musculoskeletal and myofascial pain.

OBJECTIVES: To examine the association between dysmenorrhea and musculoskeletal pain amongst university students aged 20-35 and the association between dysmenorrhea and the occurrence of MTrPs. METHODS: The study comprised two stages: a cross-sectional study evaluated the association between dysmenorrhea and musculoskeletal pain and a case-control study evaluated the association between dysmenorrhea and the occurrence of MTrPs in the abdominal and pelvic area. Initially, questionnaires such as demographics, menstruation characteristics, Numeric Pain Rating Scale (NPRS), measuring the average pain during menstruation and Nordic, were distributed to female students. Twenty subjects who suffered from menstrual pain of >3 on the NPRS (ones with the highest scores) were included in the second stage as cases. An additional 20 who had not suffered from menstrual pain (NPRS ≤3) were considered controls. All 40 subjects underwent an assessment of MTrPs by two examiners blinded to each other's results and to the group allocation of the subjects. RESULTS: We found that dysmenorrhea is a very prevalent condition among young female students. Most frequent complaints were: lower abdomen and back pain, tiredness, breast tenderness, mood changes, and an increased appetite. Pain during menstruation indicated a significant positive association with neck, low back, and hip/thigh pain during the last 12 months. The results of the palpitation conclusively showed more active MTrPs in the rectus abdominis, quadratus lumborum and paraspinal muscles in women suffering from pain during menstruation than in those who were not in pain. CONCLUSION: Our data provide an initial basis for the inclusion of a myofascial examination when evaluating women with dysmenorrhea.

Effects of myofascial trigger point dry cupping on pain and function in patients with plantar heel pain: A randomized controlled trial.

OBJECTIVE: To investigate the effects of dry cupping on calf muscle myofascial trigger points (MTrPs) on pain and function in patients with plantar heel pain. METHODS: Seventy-one patients were randomly divided into an intervention group or control group. Both groups performed stretching exercises for the calf muscle and plantar fascia and ankle dorsiflexion exercises. The intervention group also received dry cupping. The primary outcome measures were visual analogue scale (VAS), pressure pain threshold (PPT), and patient-specific functional scale (PSFS). The secondary outcomes were ankle dorsiflexion range of motion (ROM) and ankle plantar flexor strength. These measurements were performed at baseline, immediately after intervention, and after 2 days. RESULTS: Current VAS significantly decreased immediately in the intervention group (p = 0.002), but not in the control group (p ≥ 0.220). Morning VAS decreased significantly in both groups (p < 0.001) after 2 days, but decreased more in the intervention group (p = 0.006). Trigger point PPT significantly improved immediately in the intervention group (p = 0.003), but not in the control group (p = 0.112). Both groups improved significantly in PSFS (p < 0.001) and ankle dorsiflexion ROM (p < 0.001). Plantar flexor strength significantly increased immediately in the intervention group (p < 0.001), but not in the control group (p = 0.556). CONCLUSION: Adding dry cupping on calf MTrPs to self-stretching and ankle dorsiflexion exercises for patients with plantar heel pain was superior to only self-stretching and active ankle dorsiflexion exercises in pain, ankle dorsiflexion ROM, and plantar flexor strength.

A systematic review of manual therapy techniques, dry cupping and dry needling in the reduction of myofascial pain and myofascial trigger points.

INTRODUCTION: Myofascial pain with myofascial triggers are common musculoskeletal complaints. Popular treatments include manual therapy, dry needling, and dry cupping. The purpose of this systematic review was to compare the efficacy of each treatment in the short-term relief of myofascial pain and myofascial trigger points. METHODS: Search engines included Google Scholar, EBSCO Host, and PubMed. Searches were performed for each modality using the keywords myofascial pain syndrome and myofascial trigger points. The inclusion criteria included English-language, peer-reviewed journals; a diagnosis of myofascial pain syndrome or trigger points; manual therapy, dry needling, or dry cupping treatments; retrospective studies or prospective methodology; and inclusion of outcome measures. RESULTS: Eight studies on manual therapy, twenty-three studies on dry needling, and two studies on dry cupping met the inclusion criteria. The Physiotherapy Evidence Database (PEDro) was utilized to assess the quality of all articles. DISCUSSION: While there was a moderate number of randomized controlled trials supporting the use of manual therapy, the evidence for dry needling ranged from very low to moderate compared to control groups, sham interventions, or other treatments and there was a paucity of data on dry cupping. Limitations included unclear methodologies, high risk for bias, inadequate blinding, no control group, and small sample sizes. CONCLUSION: While there is moderate evidence for manual therapy in myofascial pain treatment, the evidence for dry needling and cupping is not greater than placebo. Future studies should address the limitations of small sample sizes, unclear methodologies, poor blinding, and lack of control groups.

Myofascial pain syndrome and trigger points: evaluation and treatment in patients with musculoskeletal pain.

PURPOSE OF REVIEW: Myofascial pain syndrome is a chronic pain condition characterized by the presence of myofascial trigger point, a hyperirritable painful spot involving a limited number of muscle fibers. The literature suggest that myofascial trigger points should be considered peripheral pain generators and this critical review will summarize recent findings concerning the clinical evaluation and the treatment of myofascial trigger points. RECENT FINDINGS: The clinical features of myofascial trigger points and their contribution to the patient pain and disability have been detailed in several recent studies, which support the clinical relevance of the condition. Recent studies reported that manual palpation to identify MTrPs has good reliability, although some limitations are intrinsic to the diagnostic criteria. During the last decade, a plethora of treatments have been proposed and positive effects on pain and function demonstrated. SUMMARY: The myofascial trigger point phenomenon has good face validity and is clinically relevant. Clinicians are encouraged to consider the contribution of myofascial trigger points to the patient's pain and disability through a careful medical history and a specific manual examination. Patients with myofascial trigger points will benefit from a multimodal treatment plan including dry needling and manual therapy techniques. Internal and external validity of research within the field must be improved.

A critical overview of the current myofascial pain literature - February 2019.

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

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.

A soft massage tool is advantageous for compressing deep soft tissue with low muscle tension: Therapeutic evidence for self-myofascial release.

OBJECTIVES: This study aimed to compare the amount of deep tissue pressure and muscle relaxation between a soft inflatable rubber ball (SIRB) and a hard massage ball (HMB). DESIGN: Crossover experimental design study. INTERVENTIONS: Thirty participants with neck pain (age: 65.9 ± 3.4, Neck Disability Index score: 34.0% ± 15.2) pillowed a SIRB or an HMB beneath the suboccipital region in the supine position. For the baseline condition, participants pillowed a foam block without a ball. MAIN OUTCOME MEASURES: To quantify the amount of deep-tissue pressure by a ball, compressed soft tissue thickness was measured with lateral cervical radiographs. To assess muscle relaxation, the amount of muscle tension was determined using electromyography of the sternocleidomastoid and upper trapezius muscles. To monitor the cervical lordosis in each condition, the extension angles of the cervical vertebrae were quantified using the relative rotation angles. RESULTS: The compressed soft tissue thickness in the SIRB condition was significantly lower than that in the HMB condition. The normalised muscle activities exhibited that right sternocleidomastoid muscle activity in the HMB condition was significantly higher than that in the baseline and SIRB conditions. In the SIRB and HMB conditions, Numeric Rating Scale for pain was 0.2 ± 0.5 and 5.2 ± 1.4, respectively. CONCLUSIONS: Our findings demonstrate that a SIRB is more advantageous than an HMB for pressing the soft tissue deeply. This finding would be related to reduced muscle tension and discomfort in the SIRB condition when compared with the HMB condition.
