Abstract
BACKGROUND The most important clinical problem in myofascial pain syndrome (MPS) is trigger points (TrPs). The aim of the present study was to investigate the comparison of immediate effect of deep transverse friction massage (DTFM), high-power pain threshold ultrasound (HPPTUS), and whole body vibration (WBV) on treatment of active myofascial trigger points (MTrPs). MATERIALS AND METHODS sixty six men with active TrPs of upper trapezius muscle were randomly divided into three equal groups: DTFM, HPPT US, and WBV. Pain intensity based on the Visual Analogue Scale (VAS), pressure pain threshold (PPT) and active contralateral lateral flexion range of motion (CLF ROM) of the neck were evaluated before and immediately after the interventions. RESULTS The VAS, PPT and the active CLF ROM were substantially improved after intervention in all groups (P < 0.01). When the three groups were compared regarding VAS, participants in the WBV group reported significantly more reduction in pain (P < 0.01). On comparing the interventions, there were no significant differences in PPT values (P > 0.05). The CLF ROM value in HPPTUS and WBV groups have significant increase in comparison to the DTFM group. CONCLUSION All three interventions can improve neck pain, PPT and ROM in participants with active TrPs in upper trapezius muscle, but due to the fact that the DTFM has more pressure on therapist fingers, and the HPPTUS technique requires proper interaction with the participants, WBV can be used as one of the effective intervention on active MTrPs of upper trapezius. CLINICAL TRIAL REGISTRATION NUMBER IRCT20200518047498N1.

Abstract
It is unclear which factors contribute to the developing pressure pain hypersensitivity of the upper trapezius, a type of neurophysiological hyperexcitability. The present study investigated the relationship between physical and psychological factors and pressure pain hypersensitivity of the upper trapezius for each sex. In total, 154 individuals with neck/shoulder myofascial pain participated, among 372 food service workers. Participants completed a questionnaire (Beck Depression Inventory, and Borg Rating of Perceived Exertion scale) and were photographed to measure posture. Pressure pain sensitivity, 2 range of motions (cervical lateral bending and rotation), and 4 muscle strengths (serratus anterior, lower trapezius [LT], biceps, and glenohumeral external rotator) were measured by a pressure algometer, iPhone application, and handheld dynamometer, respectively. For each sex, forward multivariate logistic regression was used to test our a priori hypothesis among selected variables that a combination of psychosocial and physical factors contributed to the risk for pressure pain hypersensitivity. In multivariate analyses, LT strength (odds ratio = 0.94, 95% confidence interval = 0.91-0.97, P = .001) was the only significant influencing factor for pressure pain hypersensitivity in men. Dominant painful ipsilateral cervical rotation range of motion (odds ratio = 0.96, 95% confidence interval = 0.92-0.99, P = .037) was the only influencing factor for pressure pain hypersensitivity in women. LT strength and dominant painful ipsilateral cervical rotation range of motion could serve as guidelines for preventing and managing pressure pain hypersensitivity of the upper trapezius in food service workers with nonspecific neck/shoulder myofascial pain.

Abstract
Severe neck-shoulder pain induces functional limitations in both life and work. The purpose of this study was to determine the characteristics of shoulder microcirculation abnormality in workers. This study recruited 32 workers and patients, both n = 16. Questionnaires were administered, and Laser Doppler Flowmetry (LDF) was used to measure microcirculatory blood flow (MBF) at the myofascial trigger points (MTrPs) on the shoulders. The absolute-deviationMMBF represented the mean MBF (MMBF) variability among subjects. The differences in the life characteristics, shoulder pain level, and microcirculatory characteristics at MTrPs between the two groups were compared. It was found that shoulder pain level was significantly higher in the patient than in the control group (p < 0.001). Deviation of the MMBF value beyond the postulated “normal range” of 60–80 was significantly higher in the patient than in the control group (p < 0.001). The MMBF deviation was significantly correlated with shoulder pain level, pain duration, and the symptom effect (p < 0.01, n = 32). A normal range for the MMBF of 60–80 on the shoulder near MTrPs is hypothesized for the first time based on this study. Noninvasive LDF can be used to assess abnormality in the MBF on shoulder MTrPs at an early stage.

Abstract
Background: Because psychosomatic diseases are pathological conditions, it is difficult to identify their degrees. The armchair sign is a test used to assess voluntary muscle relaxation. Objective: We aimed to evaluate the usefulness of the armchair sign for the diagnosis of psychosomatic-prone myofascial pain syndrome (MPS) in patients with incurable cancer. Design: This was a secondary analysis of a prospective multicenter observational clinical study. Setting/Patients: Patients with incurable cancer who were referred to palliative care services at five institutions in Japan between March 2018 and December 2018. Results: A total of 101 patients were enrolled, of whom 44 met MPS diagnostic criteria. Of these, 27 patients (61.3%) had psychosomatic-prone MPS. There was a significant association between the armchair sign and psychosomatic-prone MPS (p = 0.002). Sensitivity and specificity were 40.7% (95% confidence interval [CI]: 18.0–63.4) and 100.0%, respectively. The area under the curve score was 0.704 (95% CI: 0.553–0.855). Conclusions: The armchair sign may be useful as an ancillary test for the diagnosis of psychosomatic-prone MPS in patients with incurable cancer. Trial Registration: UMIN000031338.

Abstract
Background/Objective The intent of the current study was to compare the immediate effects of positional release therapy (PRT) and manual trigger point release (MTpR) on neck range of motion and pain in upper trapezitis. Materials and Methods Sixty participants with upper trapezius myofascial trigger points (MTrPs)' participated in this study. Subjects were randomly classified into two groups (30 in each group): the subjects in Group A received PRT in a shortened position while those in Group B received MTpR in the neutral position for the upper trapezius muscle. They received four therapy sessions every day for four days. The pain intensity and range of motion were measured using the Numerical Pain Rating Scale (NPRS) and cervical range of motion (CROM), respectively, before treatment sessions and repeated immediately after the first and fourth treatment sessions in each group till the last day of their interventions. Results Paired and unpaired t-Test was used for the data analysis. Pre- and postinterventional effects measured on each day and between groups, revealed that CROM and NPRS values were significantly improved in (MTpR) group (CROM, and NPRS P < 0.05). Conclusion Both groups (PRT and MTpR) showed an increase in range of motion on CROM and a decrease in pain intensity on the NPRS during four sessions of therapy, but MTpR showed to be more effectual in these participants.

Abstract
Background: Myofascial pain syndrome (MPS) is a painful musculoskeletal condition. The prevalence of MPS ranges from 5.9% to 38.7% in the general population. "Thor-ra-nee-san-tha-kat" (TRK) is a traditional formula included in the Thailand National List of Essential Medicines for the treatment for muscle pain caused by abdominal rigidity and for severe constipation. Objectives: The authors employed a pilot single-blind, randomized-controlled trial to compare the effectiveness of TRK and naproxen for the treatment of chronic upper trapezius MPS. Materials and Methods: Seventy-six male and female subjects, ages 25-55 years, who met the inclusion criteria were equally randomized into two groups to receive either two 500 mg capsules of TRK once daily before bed or two 250 mg naproxen tablets twice a day after meals for 14 days. Subjects assessed their level of pain using the numerical rating scale. Cervical range of motion (CROM) was determined using a goniometer, and pressure pain threshold (PPT) was assessed using an algometer. Adverse drug reactions were recorded and all items were compared within and between groups, before and after treatment. Results: The results revealed that patient pain scores after 14 days of treatment were much improved with mean differences exceeding the reference minimum clinically important difference (MCID) in both groups. However, the changes in CROM and PPT values were small and did not surpass their respective reference MCIDs except for the right lateral bending CROM for naproxen treatment. The adverse drug reactions were mild, with watery stools reported by 47% of patients in the TRK-treated group and constipation reported by 24% of those in the naproxen group. Conclusion: The administration of TRK formula for 14 days was safe and as effective as naproxen at providing short-term relief of pain in patients with chronic upper trapezius pain.

Abstract
Background: Despite the suggestion of a relationship between development or progression of myofascial pain syndrome (MPS) and psychological stress, few studies have reported its proportion or association with treatment efficacy. Objective: We aimed to investigate the proportion of MPS with psychological stress among cancer patients and to compare the efficacy of trigger point injection (TPI) in the same patients with/without psychological stress. Design: This was a prospective observational study. Setting/Patients: Participants were 205 patients with cancer who received TPIs for MPS at a hospital in Japan. Results: The proportion of patients with MPS and psychological stress was 0.57 (95% confidence interval [CI] 0.50-0.64). The TPI efficacy rate at seven days after treatment was 0.55 (95% CI 0.46-0.64) for patients with MPS and psychological stress and 0.82 (95% CI 0.74-0.90) for their counterparts without psychological stress (p < 0.004). The odds ratio for TPI efficacy seven days after treatment with psychological stress versus without psychological stress was 0.25 (95% CI 0.13-0.49). Conclusions: MPS was a clinical symptom of psychosomatic disorder in approximately half of our patients. The TPI efficacy for patients with MPS who had psychological stress was lower than for their counterparts without psychological stress. Trial registration: UMIN000041210.

Abstract
BACKGROUND Increased genu recurvatum (GR) angle is a risk factor for knee injury. Identification of factors causing GR is important for the prevention and rehabilitation of GR. Few studies have investigated the association between muscle strength and GR. OBJECTIVE To examine the association between GR angle and hip and knee muscle strength in standing workersMETHODS:The participants in this study were 110 healthy volunteers (59 male, 51 female) who performed standing work in a theme park. The GR angle, muscle strength, and strength ratio of the lower extremities were measured to determine their associations with GR. The GR angle was measured using a Smart KEMA motion sensor, and muscle strength was assessed using a Smart KEMA strength sensor. Stepwise multiple regression models were used to investigate which muscles contributed most to the extent of the GR angle. RESULTS Stepwise multiple regression analysis showed that the decreased hip external rotator to hip internal rotator ratio, increased knee extensor to knee flexor ratio, and young age were associated with an increased GR angle. CONCLUSIONS Many factors are known to increase the GR angle. However, this study investigated the roles of only hip and knee muscle strength. The results suggest that muscle strength ratios are more important than the weakness of any muscle.

Abstract
OBJECTIVE The purpose of this study was to assess the intrarater and interrater reliability of marking 2 angles with the TEMPLO software and to provide relevant information for clinical practice. METHODS A prospective test-retest study has been conducted. Four raters took measures on 2 days, with 2 weeks in between. Craniovertebral angle and trunk forward lean were drawn on 22 video frames using TEMPLO. Reliability was examined using intraclass correlation coefficients including standard errors of measurement and minimal detectable change values as measures of precision expressed in the unit of the test (°). RESULTS Intraclass correlation coefficients for intrarater and interrater reliability ranged from 0.98 to 1.00. Standard errors of measurement and minimal detectable change values ranged from 0.4° to 0.8° and 0.8° to 2.3°, respectively. CONCLUSION These results indicate excellent reliability for craniovertebral angle and trunk forward lean assessed with TEMPLO software. Changes exceeding 2.3° may be expected to fall outside the test's variability.

Abstract
BACKGROUND Because patients with nonspecific chronic low back pain (NSCLBP) are heterogeneous, subgrouping patients with NSCLBP might clarify the research findings. NSCLBP in the direction of extension movement, namely active extension pattern (AEP), is common during prolonged standing. OBJECTIVE Predictors of pain intensity and dysfunction were determined in prolonged standing service workers (PSSWs) with NSCLBP subclassified as AEP in the motor impairment subgroup. METHODS Variables were measured using questionnaires including a visual analog scale (VAS), the Oswestry Disability Index (ODI), Borg Rating of Perceived Exertion (RPE) Scale, and Korean Occupational Stress Scale (KOSS). Postural assessment was performed by measuring pelvic anterior tilting angle (PATA). The smart KEMA measurement system was used to evaluate hip flexion, hip extension (HE), and knee flexion range of motion (ROM), as well as hip extensor strength, hip abductor strength (HArS), hip external rotator strength (HERrS), hip internal rotator strength, knee extensor strength, and knee flexor strength, and lumbopelvic stability (LS) in 78 PSSWs with NSCLBP subclassified as AEP. RESULTS In prediction models, HArS, LS, PATA, KOSS and HE ROM accounted for 40.1% of the variance in the VAS (p < 0.05); predictors of dysfunction included the HERrS and age, which accounted for 11.9% of the variance in the ODI (p < 0.05) in multiple regression models when using a stepwise selection procedure. CONCLUSIONS The present results indicate that HArS and HERrS, LS, PATA, KOSS, HE ROM and age should be considered for evaluating and predicting NSCLBP subclassified as AEP in PSSWs, and when designing interventions.
