“…The pressure pain threshold (PPT) for the examination of MTPs is the minimal force that induces pain. [6][7][8][9] Infrared thermography is a non-ionizing and noninvasive imaging technique that detects the distribution of body surface heat. It detects, records and transforms into images the infrared radiation emitted by the human skin, reflecting in real-time the microcirculatory dynamic of the cutaneous surface of the patients.…”

Objectives: The aim of the study was to identify and correlate myofascial trigger points (MTPs) in the masticatory muscles, using thermography and algometry. Methods: 26 female volunteers were recruited. The surface facial area over the masseter and anterior temporalis muscles was divided into 15 subareas on each side (n 5 780). This investigation consisted of three steps. The first step involved thermographic facial examination, using lateral views. The second step involved the pressure pain threshold (PPT), marking the MTP pattern areas for referred pain (n 5 131) and local pain (n 5 282) with a coloured pencil, and a photograph of the lateral face with the head in the same position as the infrared imaging. The last step was the fusion of these two images, using dedicated software (ReporterH 8.5-SP3 Professional Edition and QuickReportH 1.2, FLIR Systems, Wilsonville, OR); and the calculation of the temperature of each point. Results: PPT levels measured at the points of referred pain in MTPs (1.28 ¡ 0.45 kgf) were significantly lower than the points of local pain in MTPs (1.73 ¡ 0.59 kgf; p , 0.05). Infrared imaging indicated differences between referred and local pain in MTPs of 0.5 u C (p , 0.05). Analysis of the correlation between the PPT and infrared imaging was done using the Spearman non-parametric method, in which the correlations were positive and moderate (0.4 # r , 0.7). The sensitivity and specificity in MTPs were 62.5% and 71.3%, respectively, for referred pain, and 43.6% and 60.6%, respectively, for local pain. Conclusion: Infrared imaging measurements can provide a useful, non-invasive and nonionizing examination for diagnosis of MTPs in masticatory muscles.

“…Studies performed to date have shown that in MPS, the use of an algometer is safe in terms of determining the tenderness of the trigger points. [16][17][18][19] The second investigator identified the patient groups using the RAS system. If the patient was in the oral flurbiprofen group, the tablets were given to the patients along with an explanation of how and when to take them, and if the patient was in one of the needling groups, the procedures were performed by the second investigator.…”

Amaç: Bu çalışmada boyun ve sırt bölgesinde miyofasiyal ağrı sendromu (MAS) bulunan hastalarda kuru iğneleme, lidokain enjeksiyonu ve oral flurbiprofen tedavilerinin etkinliği karşılaştırıldı. Hastalar ve yöntemler:Bu prospektif çalışmaya toplam 60 hasta (7 erkek, 53 kadın; ort yaş 33.7 yıl; dağılım 18-50 yıl) dahil edildi. Hastalar blok randomizasyon ile üç gruba ayrıldı. Bir gruba tetik noktalara kuru iğneleme, bir gruba lidokain enjeksiyonu (çift kör) ve diğer gruba yedi gün süresince 200 mg/gün oral flurbiprofen tedavisi verildi. Ayrıca hastaların tümüne tutulan kasın gerilmesini temel alan standart bir ev egzersiz programı da verildi. Tedavi öncesi ve tedaviden sonraki üçüncü ve 14. günlerde ağrı şiddeti, görsel analog ölçeği (GAÖ) ile tetik noktaların duyarlılık derecesi algometre ile boyun ve omuz aktif eklem hareket açıklıkları gonyometre ile ve yaşam kalitesi Nottingham Sağlık Profili ile değerlendirildi. Bulgular: Üç grupta da tedaviden sonraki üçüncü ve 14. günlerde tedavi öncesine göre ağrı şiddeti, tetik nokta hassasiyeti, eklem hareket açıklıkları ve yaşam kalitesi açısından iyileşme saptandı. Tedavilerin etkinlikleri açısından gruplar arasında anlamlı fark bulunmadı.Sonuç: Miyofasiyal ağrı sendromunun tedavisinde, ev egzersizleri ile birlikte kuru iğneleme, lidokain enjeksiyonu ve oral flurbiprofen tedavilerinin tümü etkindir.Anahtar sözcükler: Kuru iğneleme; flurbiprofen; lidokain; miyofasiyal ağrı sendromu. Objectives:The aim of this study was to assess and compare the efficiency of dry needling, lidocaine injection and oral flurbiprofen treatments in patients with myofascial pain syndrome (MPS) involving the neck and back region. Patients and methods:A total of 60 patients (7 males, 53 females; mean age 33.7 years; range 18 to 50 years) were included in this prospective study. The patients were divided into three groups by block randomization. Each group was assigned to dry needling for trigger points, lidocaine injection (double blind) or oral flurbiprofen 200 mg/day over seven days. All patients were also prescribed a standardized home exercise program based on stretching of the affected muscles. Before treatment and on the third and 14 days after treatment, pain severity was assessed by visual analog scale (VAS), degree of tenderness at the trigger points by algometry, active joint range of motion of the neck and shoulders by goniometry, and the quality of life by Nottingham Health Profile.Results: There was a significant improvement in pain severity, trigger point tenderness, joint range of motion, and quality of life in all three groups on the third and 14 th days of treatment. No significant difference was found in treatment efficiency among the groups. Conclusion:Treatments with dry needling, lidocain injection and oral flurbiprofen along with home exercises are all effective in the management of MPS.

“…The results are still controversial. Some studies have reported significant improvement through use of STR in combination with other modalities as a part of MTrP treatment [12][13][14][15][16] . The combination treatment has been proved to be effective in treating MTrP rather than STR alone 14,16) .…”

Effects of Strain Counter-Strain and Stretching Techniques in Active Myofascial Pain Syndrome

Abstract. [Purpose] This study investigated the effects of passive stretching (STR) and strain counter-strain (SCS) techniques in subjects with myofascial pain syndrome (MPS) as measured by a visual analogue scale (VAS), pressure pain threshold (PPT), displacement pain threshold (DPT), active range of motion (AROM), and patients perception of change (PPC).[Subjects] Twenty volunteers with active MPS in the upper trapezius muscle participated in the study.[Methods] The subjects were randomly allocated to either a STR or SCS treatment group. Evaluations were performed at before, immediately, one hour, and one day after treatment. [Results] No significant difference between groups were found. However, there was a significant improvement of VAS an hour after SCS treatment. The improvement seemed to be maintained after treatment. The STR group showed a significant decrease of DPT between immediately and a day after treatment, indicating less tissue compliance.[Conclusion] The SCS treatment helps relieve the pain one hour after treatment in subjects with active MPS.
