 The current study aimed to evaluate the pain perception among patients with Myofascial pain syndrome in both genders. The study was crossectional survey design. Data was collected using consecutive sampling technique. 170 Patients with Myofacial pain syndrome were taken as the sample of the study who visited dental teaching hospital from January, 2020 to April, 2021. Chi-square test was used to assess the pain perception among patients with Myofascial pain syndrome in both genders using SPSS version 23.0. The results of chi-square revealed a significant difference between both genders in terms of prevalence of Myofascial pain syndrome (X2=9.110, P=.011). In conclusion, Males were higher in reporting severe pain while females were higher in reported moderate myofascial pain.
 
 

Prevalence of Myofascial Pain Syndrome and Efficacy of Trigger Point Injection in Patients with Incurable Cancer: A Multicenter, Prospective Observational Study (MyCar Study).

Myofascial pain syndrome (MPS) is caused by overload or disuse of skeletal muscles. Patients with cancer are often forced to restrict their movement or posture for several reasons. The study was conducted to investigate the prevalence and risks of MPS in patients with incurable cancer. The efficacy of trigger point injection (TPI) was also explored. This was a multicenter, prospective observational study. Patients with incurable cancer who started receiving specialist palliative care were enrolled. We investigated the MPS in this population and accompanying risk factors for restricting body movement. Pre- and post-TPI pain was also evaluated using a Numerical Rating Scale (NRS) in patients who received TPI. The primary outcome was the prevalence of MPS. A total of 101 patients were enrolled from five institutions in Japan. Most of the patients (n = 94, 93.1%) had distant metastases, and half of the patients (50, 49.5%) received anticancer treatment. Thirty-nine (38.6%) patients had MPS lesions at 83 sites. Multivariate analysis revealed that the significant risk factor for MPS was poor Performance Status (PS) (odds ratio 3.26; 95% confidence interval [CI] 1.18-9.02, P = .023). We performed TPI for 40 out of 83 MPS lesions. Mean NRS for MPS before TPI was 7.95, which improved to 4.30 after TPI (P < .001). MPS was common in patients with incurable cancer and the risk factor identified in this study was poor performance status. TPI could be a treatment option.

Prevalence of head and neck Myofascial Pain Syndrome in a South American population

Objective: To diagnose the prevalence of Myofascial Pain Syndrome (MPS) with respect to sex, age, affected muscle, socioeconomic stratum, occupation and associated symptoms.&#x0D; Methods: This is a descriptive, cross-sectional study of a convenience sample of 220 outpatients who attended the Faculty of Dentistry of the Universidad de Antioquia Medellín-Colombia, between September 30th, 2015 and September 7th, 2017. Interventions: not applicable. Main measure of results: Myofascial Pain Syndrome.&#x0D; Results: 26.4% of our sample presented symtoms of MPS. More women than men were found to have MPS. The number of cases decreases with age. The most affected muscle is the trapezium, followed by the temporalis, and there are no significant differences in terms of socioeconomic stratum and occupation. The most frequently reported associated symptom is neck pain.&#x0D; Conclusion: Because there is such a high prevalence, and on a global scale, we believe it is important to establish effective means of diagnosis and adequate measures for the prevention and treatment of this pathology.

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.

A Comprehensive Review of the Treatment and Management of Myofascial Pain Syndrome.

Myofascial pain syndrome (MPS) is a musculoskeletal pain condition that stems from localized, taut regions of skeletal muscle and fascia, termed trigger points. The purpose of this comprehensive review is to provide updated information on prevalence, pathophysiology, and treatment modalities with a focus on interventional modalities in managing MPS. Though MPS can present acutely, it frequently presents as a chronic condition, affecting up to 85% of adults during their lifetime. MPS is an often-overlooked component of pain with overarching effects on society, including patient quality of life, physical and social functioning, emotional well-being, energy, and costs on health care. The prevalence of MPS is generally increased among patients with other chronic pain disorders and has been associated with various other conditions such as bladder pain syndrome, endometriosis, and anxiety. MPS is poorly understood and remains a challenging condition to treat. Non-pharmacologic treatment modalities such as acupuncture, massage, transcutaneous electrical stimulation, and interferential current therapy may offer relief to some patients with MPS. Additional studies are warranted to get a better understanding of managing myofascial pain.

Acute effects of myofascial induction technique in plantar fascia complex in patients with myofascial pain syndrome on postural sway and plantar pressures: A quasi-experimental study

ObjectivesThe prevalence of myofascial pain syndrome varies from 21% 93%. Several studies have shown that myofascial induction is effective in treating myofascial pain syndrome. Although these techniques have shown some effectiveness in clinical practice, there have been little study into their effects, and have deep effects. The purpose of this study was to investigate if the application of a single myofascial induction technique for each foot, targeted to the plantar fascia resulted in changes in balance and footprint variables. DesignA quasi-experimental study. SettingAn outpatient clinic. Subjects20 healthy participants (12 females and 8 males) were evaluated pre and post Myofascial induction technique for each foot in plantar fascia during 5 min. MethodsWe measured static footprint and stabilometry variables in asymptomatic subjects. The footprint surface area was divided: bilateral rear foot, bilateral midfoot, bilateral fore foot. ResultsWe found differences in the footprint variables: maximun pressure in forefoot (p = 0.025), surface in forefoot (p = 0.03). The myofascial induction has no effects on stabilometry variables. ConclusionsThe immediate effects of the longitudinal technique of myofascial induction of the plantar fascia are the increase of surface and maximum pressure in fore foot.

Prevalence of myofascial pain syndrome in patients with incurable cancer

BackgroundMyofascial pain syndrome (MPS) is a condition that involves skeletal muscles. It is caused by overload or disuse of muscles and is characterized by extreme tenderness in the muscles with taut bands. Treatment for MPS is different from that for cancer-related pain. Cancer patients have many factors that cause restriction of body movement and posture. Although cancer patients appear to demonstrate risk factors for MPS, its prevalence has not been reported in patients with incurable cancer. This study was conducted to investigate the prevalence of MPS in patients with incurable cancer. MethodsA retrospective chart review. The data for patients with incurable cancer who received palliative care at our department between September 2015 and March 2016 were investigated. We examined the prevalence of MPS, which was diagnosed on the basis of the Rivers criteria (RC) and Simons criteria (SC). We also examined the following factors associated with MPS: performance status (PS), use of medical devices, and primary cancer sites. The primary outcome was the prevalence of MPS based on RC. Secondary outcomes included the prevalence of MPS based on SC and the relationship between MPS and either PS or medical devices. ResultsThirty-four patients with incurable cancer were identified. MPS based on RC or SC was detected in 10 (29%) and 20 (59%) patients, respectively. Twenty-two of 34 patients who complained of pain, 10 (45%) had MPS based on RC and 20 (90%) had MPS based on SC. Age and central venous port were risk factors for MPS by multivariate analysis. ConclusionA very high prevalence of MPS was detected in our study population. MPS should be considered when patients with incurable cancer complain of pain.

Prevalence of myofascial pain syndrome in patients with incurable cancer.

97 Background: Myofascial pain syndrome (MPS) is a condition that involves skeletal muscles. It is caused by overload or disuse of muscles and is characterized by extreme tenderness in the muscles with taut bands. Treatment for MSP is different from that for cancer-related pain. Cancer patients have many factors that cause restriction of body movement and posture. Although cancer patients appear to demonstrate risk factors for MPS, its prevalence has not been reported in patients with incurable cancer. This study was conducted to investigate the prevalence of MPS in patients with incurable cancer. Methods: The data for patients with incurable cancer who received palliative care by our department between September 2015 and March 2016 were retrospectively investigated. We examined the prevalence of MPS. MPS was diagnosed on the basis of the Rivers criteria (RC) and Simons criteria (SC). We also examined the following factors associated with MPS: performance status (PS), use of medical devices (MD), and primary cancer sites. The primary outcome was the prevalence of MPS using the RC. Secondary outcomes included the prevalence of MPS using the SC, and the relationship between MPS and either PS or MD. Results: Thirty-four patients with incurable cancer were identified. The clinical characteristics are as follows: age (median, range): 65 (39-89) years; male/female ratio: 16/18; primary sites: pancreas (n = 8), breast (n = 8), lung (n = 4), colorectal (n = 4), head and neck (n = 2), and other primary sites (n = 8). Seventeen of 34 patients (50%) had a PS 3 or 4. Twenty-two patients (64.7%) complained of pain. MPS using the RC was detected in 10 patients (29%). MPS using the SC was detected in 20 patients (59%). Of 22 patients who complained of pain, MPS using the RC was detected in 10 (45%) patients and MPS using the SC was detected in 20 (90%) of patients. Patients with central venous port (CVP) devices had a significantly higher number of MPS lesions than patients without CVP devices (p = 0.029). Conclusions: A very high prevalence of MPS was detected in our study population. MPS should be considered when patients with incurable cancer complain of pain. A multi-center prospective study will be conducted to confirm our findings.

Targeting Myofascial Taut Bands by Ultrasound

Myofascial pain syndrome (MPS) is a frequent diagnosis in chronic pain and is characterized by tender, taut bands known as trigger points. The trigger points are painful areas in skeletal muscle that are associated with a palpable nodule within a taut band of muscle fibers. Despite the prevalence of myofascial pain syndrome, diagnosis is based on clinical criteria alone. A growing body of evidence that suggests that taut bands are readily visualized under ultrasound-guided exam, especially when results are correlated with elastography, multidimensional imaging, and physical exam findings such as local twitch response. The actual image characteristic in B mode appears to be controversial. Ultrasonography provides an objective modality to assist with diagnosis and treatment of trigger points in the future.

Central poststroke pain: somatosensory abnormalities and the presence of associated myofascial pain syndrome

BackgroundCentral post-stroke pain (CPSP) is a neuropathic pain syndrome associated with somatosensory abnormalities due to central nervous system lesion following a cerebrovascular insult. Post-stroke pain (PSP) refers to a broader range of clinical conditions leading to pain after stroke, but not restricted to CPSP, including other types of pain such as myofascial pain syndrome (MPS), painful shoulder, lumbar and dorsal pain, complex regional pain syndrome, and spasticity-related pain. Despite its recognition as part of the general PSP diagnostic possibilities, the prevalence of MPS has never been characterized in patients with CPSP patients. We performed a cross-sectional standardized clinical and radiological evaluation of patients with definite CPSP in order to assess the presence of other non-neuropathic pain syndromes, and in particular, the role of myofascial pain syndrome in these patients.MethodsCPSP patients underwent a standardized sensory and motor neurological evaluation, and were classified according to stroke mechanism, neurological deficits, presence and profile of MPS. The Visual Analogic Scale (VAS), McGill Pain Questionnaire (MPQ), and Beck Depression Scale (BDS) were filled out by all participants.ResultsForty CPSP patients were included. Thirty-six (90.0%) had one single ischemic stroke. Pain presented during the first three months after stroke in 75.0%. Median pain intensity was 10 (5 to 10). There was no difference in pain intensity among the different lesion site groups. Neuropathic pain was continuous-ongoing in 34 (85.0%) patients and intermittent in the remainder. Burning was the most common descriptor (70%). Main aggravating factors were contact to cold (62.5%). Thermo-sensory abnormalities were universal. MPS was diagnosed in 27 (67.5%) patients and was more common in the supratentorial extra-thalamic group (P <0.001). No significant differences were observed among the different stroke location groups and pain questionnaires and scales scores. Importantly, CPSP patients with and without MPS did not differ in pain intensity (VAS), MPQ or BDS scores.ConclusionsThe presence of MPS is not an exception after stroke and may present in association with CPSP as a common comorbid condition. Further studies are necessary to clarify the role of MPS in CPSP.
