Objectives : The purpose of this study is to compare the effectiveness between myofascial release technique and ultrasound in subjects with myofascial pain syndrome. Method : Twenty subjects with myofascial pain syndrome were randomly assigned to a myofascial release technique group(n=10) or an ultrsound group(n=10). The Cervical Range of Motion(C-ROM) instrument was used to measure cervical range of motion. Electromyography(EMG) was used to measure muscle power sternocleidomastoid and upper trapezius. Result : The result of this study shows there were no significant differences in ROM increase and muscle power increase between the myofascial release technique group and the ultrasound group. In the group with Myofascial Release Technique, the average score was $61.40{\pm}11.12$ in SCM flexion of C-ROM and $127.87{\pm}4.24$ in Rt. upper trapezius extension of EMG. In the group with ultra sound, the average score was $68.60{\pm}10.02$ in SCM flexion of C-ROM and $131.50{\pm}5.45$ in Rt. upper trapezius extension of EMG. Conclusion : The results suggest that there was no significant difference between two therapeutic techniques.

Purpose: Myofascial syndrome is a chronic muscle pain caused by repetitive motions with stress-related muscle tension. This study aimed to investigate the validity and reliability of the evidence for diagnosing myofascial pain syndrome in trapezius muscle using a pressure algometer and surface electromyography. Methods: The experiments were performed using a total of 10 subjects, and the target locations were determined by means of a pressure algometer in the right upper trapezius muscle. The part with the lowest pain value as the trigger point and the part with the highest pain value as the non-pain trigger point were selected for measuring the locations. The median frequency and average frequency were measured in those locations with electromyography. To check the muscle fatigue, the upper trapezius muscle was moved up and down for 2 seconds at 5-second intervals in 30 seconds. The measured values were evaluated using the independent paired t-test and MannWhitney U-test. Results: The median frequency at the non-trigger point (13.7) was significantly higher than that at the trigger point (7.3). Furthermore, the mean frequency (14.7) at the non-trigger point was significantly higher than that at the trigger point (6.3). Conclusion: The results showed the correlations between the trigger points of the muscle pain and frequency analysis of surface electromyography. Thus, this study may be possible to use as a diagnostic tool for myofascial pain syndrome.

Trigger point injection treatment is an effective and widely applied treatment for myofascial pain syndrome. The trapezius muscle frequently causes myofascial pain in neck area. We herein report a case in which direct pulsed radiofrequency (RF) treatment was applied to the trapezius muscle. We observed that the RF treatment produced continuous pain relief when the effective duration of trigger point injection was temporary in myofascial pain.

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.

The purpose of this review was to examine the clinical characteristics of patients who had a diagnosis of Myofascial Pain Syndrome(MPS). Myofascial pain is a painful condition of skeletal muscle characterized by the presence of one or more trigger points. A trigger point(TrP) is a focus of hyperirritability in a tissues. Of the patients with MPS, 21(44.7 %) were male and 26(55.3 %) were female. The mean duration of MPS was 9.6 months for males and 11.3 months for females. Trigger points with associated referred patterns of pain were found in muscles of the post neck(trapezius, infrasupinatus) and in quadratus lumborum muscle. Patients reported increased fatigue(87.2 %), tingling sensation(66.0 %), numbness(66.0 %), tension(55.3 %), anxiety(44.7 %), headache (59.6 %), pilomotor activation(59.6 %).

Background: Myofascial pain syndrome (MPS) is a regional musculoskeletal pain disorder that is caused by myofascial trigger points. The objective of this study was to determine the prevalence of MPS among chronic back pain patients, as well as to identify risk factors and the outcome of this disorder. Methods: This was a prospective observational study involving 126 patients who attended the Pain Management Unit for chronic back pain between 1st January 2009 and 31st December 2009. Data examined included demographic features of patients, duration of back pain, muscle(s) involved, primary diagnosis, treatment modality and response to treatment. Results: The prevalence of MPS among chronic back pain patients was 63.5% (n = 80). Secondary MPS was more common than primary MPS, making up 81.3% of the total MPS. There was an association between female gender and risk of developing MPS ($x^2$ = 5.38, P = 0.02, O.R. = 2.4). Occupation, body mass index and duration of back pain were not significantly associated with MPS occurrence. Repeated measures analysis showed significant changes (P < 0.001) in Visual Analogue Score (VAS) and Modified Oswestry Disability Score (MODS) with standard management during three consecutive visits at six-month intervals. Conclusions: MPS prevalence among chronic back pain patients was significantly high, with female gender being a significant risk factor. With proper diagnosis and expert management, MPS has a favourable outcome.
