Differential diagnosis of posterior neck pain is very challenging based on symptoms and physical examination only. Retropharyngeal calcific tendinitis is a rare and frequently misdiagnosed entity in various causes of neck pain. It results from calcium hydroxyapatite deposition in the longus colli muscle which is characterized by severe neck pain, painful restriction of neck movement, dysphagia, and odynophagia. We herein report a case of a patient with acute retropharyngeal calcific tendinitis, who complained of posterior neck pain, initially diagnosed and treated as a myofascial neck pain syndrome.

PURPOSE: Myofascial pain syndrome (MPS) is thought to be, the least understood and most frequently misdiagnosed disease. With appropriate diagnosis, pain trigger point injection has been proven its effectiveness, so I investigated the usefulness of pain trigger point injection for the treatment of MPS. METHODS: Twelve patients with clinical MPS were evaluated. Pain trigger points were identified by using the positive jump response to the operator's finger pressure. After the pain trigger points had been identified, 2 ml of lidocaine (Travel's technique) were injected. RESULTS: Of the total of 12 patients investigated, include self-diagnosis, 6 (50%) were misdiagnosed mainly as neurosis. These 12 patients had 33 pain trigger points. The pain trigger points were distributed mainly in the chest, 8 patients (66%), and 25 points (76%). As to the duration of pain, in 10 patients, the pain dramatically disappeared within 5 minutes. In the remaining two patients improved symptoms were noted within 20 minutes after injection. CONCLUSIONS: The proper diagnosis of MPS, which is frequently misdiagnosed as neurosis, or some other physiologic and psychologic diseases was the first step and the mainstay in the treatment of MPS. This study suggests that in the diagnosis of MPS, the most practically useful method in the emergency room is to confirm the positive jump response, including tout band and referred pain, by using finger pressure. Pain trigger point injection therapy was dramatically effective, so hopefully it will be available allow clinicians as a possible treatment to better care for patients suffering from MPS.

Differential diagnosis of posterior neck and occipital pain is difficult based on symptoms and physical examination only. We report a case of patient who complained of pain in the posterior neck and occiput, with the initial diagnosis of myofascial pain syndrome, but who did not improve with conventional treatments. Magnetic resonance imaging revealed a cervical intraspinal tumor, and the patient developed subsequent motor weakness and sensory changes. Comprehensive diagnostic approaches are strongly recommended when the patient manifests symptoms unresponsive to treatment.

OBJECTIVE: This study was carried out to investigate if the measurement of range of motion(ROM) could be applied in the diagnosis of Myofascial Pain Syndrome(MPS) and to determine the severity by analyzing ROM in MPS patients. METHODS: The study subjects were 476 female telephone number information service workers. Southampton Protocol and Pittsburgh Protocol were used to diagnose MPS and to measure ROM. ROMs were measured by 2 inclinometers exercising each shoulder passively and actively in 5 directions ; abduction, forward flexion, extension, external rotation, and internal rotation. RESULTS: Compared to the normal group (n=147), the mean of right side ROM in the subjects (n=270) with same side MPS was 2.1 degrees(SD=11.5) lesser in active extension and 1.7 degrees(SD=10.4) lesser in passive extension. Compared to the mild group (n=210), the mean of right side ROM in the patients with same side severe MPS (n=58) was lesser in all directions. Especially in active forward flexion, passive forward flexion, active extension, passive extension and active external rotation, ROM in the subjects with severe MPS was lesser by 6.5 degrees(SD=13.1), 5.1 degrees(SD=12.8), 5.9 degrees(SD=11.8), 5.0 degrees(SD=10.6) and 3.9 degrees(SD=9.8), respectively, than those of the subjects with mild MPS. Compared to the subjects with left side mild MPS(n=172), ROM in the subjects with left side severe MPS (n=59) was 5.3 degrees(SD=13.3) lesser in active forward flexion. CONCLUSIONS: In this study, ROMs in the subjects with severe MPS tended to be lesser than those in mild patients. This tendency was more prominent in the right side than the left, active range of motion than passive and forward flexion and extension than others. The results of this study are expected to help diagnose shoulder MPS and determine severity.

OBJECTIVES: This study was conducted to investigate the prevalence of playing-related musculoskeletal disorders (PRMDs) of some music college freshmen majoring in string instruments. METHODS: The study subjects were 199 freshmen majoring in strings at three colleges in Seoul and surrounds. The symptom prevalence and related factors of PRMDs were surveyed with a self-administered questionnaire. The Southampton Protocol was used to diagnose PRMDs. RESULTS: The freshmen had played for 9 years and 7 months on average. The symptom prevalence of PRMDs according to the modified-NIOSH surveillance criteria was 73.4%. The shoulder was the most prevalent symptom complaint site. The prevalence of PRMDs by the Southampton Protocol was 54.3% and myofascial pain syndrome was the most common. The instrument (violin or viola vs. cello or bass), regular breaks, self perceived evaluation of playing posture and regular computer use had a significant association with the symptom prevalence of PRMDs in univariate logistic regression analysis (p<0.05). The instrument, regular breaks and regular computer use were significant variables affecting the symptom prevalence of PRMDs in multivariate logistic regression analysis (p<0.05). CONCLUSIONS: This study suggests that music college freshmen playing strings are a high risk group for musculoskeletal disorders. Therefore, the prevention of PRMDs requires the establishment of an ergonomic playing-environment, and the education of comfortable posture and stretching program such as musical warming up and physical stretching. It is especially important to form an effective treatment and rehabilitation system based on earlier diagnosis for musicians who are suffering from the PRMDs.

To review the literature of acupuncture at trigger point for myofascial pain syndrome from the main selected points (trigger point), the mechanism of Chinese medicine and modern research and its clinical application. The results show that acupuncture at trigger point has significant effect on the myofascial pain syndrome, which could be influenced by the type of needle, manipulation, insertion angle and depth of the needles. However, the involved studies at present are still far from enough and lack of systematic study with multivariate analysis, it is needed to be improved that some problems about the clinical diagnosis and basic research.

OBJECTIVE: The diagnosis of myofascial pain syndrome (MPS) is commonly made by Simons' clinical diagnostic criteria which is mainly based on patients' complaints, so it is difficult to distinguish from malingering. The purpose of this study is to evaluate local twitch response by needling (LTR) as an objective diagnostic criterion of MPS. METHOD: Forty four industrial designers complaining of regional pain in neck, shoulder, or upper arm were examined by a physiatrist. If trigger point was detected, local twitch response by needling was confirmed and than severity was measured by 4 grades. Sensitivity, specificity, and positive predictive value of local twitch response was calculated with diagnosis made by Simons' clinical diagnostic criteria. Correlation between grade of local twitch response and sum of clinical features in Simons' criteria was also evaluated. RESULTS: Local twitch response by needling was corresponding with the diagnosis of MPS by Simons' criteria (sensitivity 100%, specificity 96.7%, positive predictive value 93.3%), and the severity of local twitch response was significantly associated with sum of clinical features in Simons' criteria (Spearman correlation 0.950; p=0.048) CONCLUSION: Local twitch response by needling is an important and objective diagnostic criterion of MPS.

OBJECTIVETo study clinical value of shear wave elastography (SWE) in the evaluation of neck-shoulder myofascial pain syndrome.

METHODSFrom December 2013 to July 2014,30 patients diagnosed as neck-shoulder myofascial pain syndrome were in the treatment group,including 17 males and 13 females, with an average age of (44 ± 3) years old. Thirty healthy people were in the control group, including 22 males and 8 females, with a mean age of (37 ± 5) years old. The patients in the treatment group were treated with manipulation, once every other day, total 7 times. The SWE was used to detect tension part of trapezius muscle of patients in the treatment group before and after treatment, as well as to detect muscle belly at the descending part of trapezius muscle in the control group. The tissue elasticity and Yang's modulus value were recorded and compared.

RESULTSThe tissue elasticity chart of patients in the treatment group before treatment was mainly greenish blue with the score of 3.70 ± 1.53, and the Yang's modulus was (43.4 ± 15.6) kPa. The tissue elasticity figure after treatment was mainly blue with the score of 2.40 ± 0.87, and the Yang's modulus was (29.0 ± 5.9) kPa. Whereas in the control group, the tissue elasticity figure was mainly blue with the score of 1.60 ± 0.72, and the Yang's modulus was (24.0 ± 7.6) kPa. These were statistical differences between the two groups (P = 0.000).

CONCLUSIONSWE can be used as an evaluation method of manipulation treatment for neck-shoulder myofascial pain syndrome, which is an objective and sensitive detection method.

OBJECTIVES: The objective of this study was to identify the musculoskeletal co-morbidities of neck pain of myofascial origin among IT professionals. METHODS: A retrospective report analysis of 5357 IT professionals from various IT companies in India was conducted. Demographic details, type and intensity of the musculoskeletal problems, employee feedbacks on status of musculoskeletal health and physician's diagnosis were analysed. Descriptive statistics were used to describe the age, gender, body area affected and nature of work. Chi square test was used to find the association between musculoskeletal co-morbidities and myofascial neck pain (MNP). RESULTS: The study participants were predominantly males (71%). 41% of the population used laptops, 35% desktops and 24% both. Neck pain was the commonest reported symptom, followed by low back, shoulder and arm pain respectively. Statistical analysis also revealed that low back pain and shoulder pain, had a significant association with neck pain. Further analysis revealed that there was a significant association between the presence of MNP and thoracic outlet syndrome (p < 0.001) and fibromyalgia syndrome (p < 0.001). Other than the listed co-morbidities, eye strain was also found to be associated with MNP. CONCLUSIONS: Low back pain and shoulder pain was found to be co morbid symptoms noted among IT professionals with MNP. Thoracic outlet syndrome and fibromyalgia were found to be the most commonly associated disorders with MNP among IT professionals.

Intramuscular hemangioma, an infrequent but important cause of musculoskeletal pain, is often difficult to establish the diagnosis clinically. This report describes a case of a 32-yr-old woman who presented with severe left calf pain for 10 yr. Initial conservative treatments consisting of intramuscular electrical stimulation, herb medication, acupuncture, and intramuscular lidocaine injection under the diagnosis of myofascial pain syndrome in other facilities, failed to alleviate the symptoms. On physical examination, there was no motor weakness or sensory change. Conventional radiography of the leg revealed a soft tissue phlebolith. Conventional angiography study showed hemangioma. Intramuscular hemangioma within the soleus muscle was confirmed by magnetic resonance imaging. Following surgical excision of the hemangioma, the patient's symptom resolved completely. Intramuscular hemangioma is a rare cause of calf pain and should be considered in the differential diagnosis if a patient with muscle pain, particularly if associated with a soft tissue mass, fails to respond to conservative treatment.
