Dry needling of the trapezius muscle in office workers with neck pain: a randomized clinical trial

Background: Neck pain is a frequent complaint in office workers. This pain can be caused by myofascial trigger points (MTrPs) in the trapezius muscle. This study aimed to determine the effectiveness of deep dry needling (DDN) of active MTrPs in the trapezius muscle.

Methods: A randomized, single blinded clinical trial was carried out at the Physical Therapy Department at Physiotherapy in Women's Health Research Group at Physical Therapy Department of University of Alcalá, in Alcalá de Henares, Madrid, Spain. Forty-four office workers with neck pain and active MTrPs in the trapezius muscle were randomly allocated to either the DDN or the control group (CG). The participants in the DDN group were treated with DDN of all MTrPs found in the trapezius muscle. They also received passive stretch of the trapezius muscle. The CG received the same passive stretch of the trapezius muscle only. The primary outcome measure was subjective pain intensity, measured using a visual analogue scale (VAS). Secondary outcomes were pressure pain threshold (PPT), cervical range of motion (CROM) and muscle strength. Data were collected at baseline, after interventions and 15?days after the last treatment.

Results: Differences were found between the DDN group and the CG for the VAS (P?P?P?P?Discussion: Deep dry needling and passive stretch seems to be more effective than passive stretch only. The effects are maintained in the short term. The results support the use of DDN in the management of trapezius muscle myofascial pain syndrome in neck pain.     

剪切波超声弹性成像技术和表面肌电图在颈肩肌筋膜疼痛综合征疗效评估中的应用

目的:探讨剪切波超声弹性成像(SWE)技术和表面肌电图(sEMG)在颈肩肌筋膜疼痛综合征(MPS)疗效评估中的应用价值。方法:回顾性分析2017年10月~2019年10月间医院收治的90例颈肩(MPS)患者的临床资料,所有患者均接受4个疗程(7d为1疗程)的针刺联合推拿治疗,根据治疗后1个月的疗效划分为A组(54例)、B组(36例)。于治疗前、后采用SWE检测两组患者的杨氏模量值、触发点厚度、组织弹性图评分,并使用sEMG检测平均振幅值、平均频率斜率值,并使用受试者工作曲线(ROC)分析以上指标对颈肩MPS患者疗效的评估价值。结果:治疗前,两组患者的组织弹性图评分、杨氏模量值、筋膜厚度、平均振幅值、平均频率斜率等比较,差异均无统计学意义(P_均>0.05)。治疗后,两组患者的组织弹性图评分、杨氏模量值、筋膜厚度等均低于治疗前(A组B组),差异均具有统计学意义(P_均<0.05)。ROC曲线显示,组织弹性图评分、杨氏模量值、筋膜厚度、平均振幅值、平均频率斜率评估颈肩MPS患者疗效的AUC分别为0.750、0.744、0.836、0.812、0.752,具有一定的价值,且联合检查的价值较高(AUC=0.957,P<0.01)。结论:剪切波超声弹性成像技术联合表面肌电图可用于颈肩肌筋膜疼痛综合征疗效评估。     

Placental Elasticity as a New Non-invasive Predictive Marker of Pre-eclampsia

Point shear wave elastography is an ultrasonography technique used to evaluate tissue elasticity. We examined whether placental elasticity is useful for predicting the onset of pre-eclampsia. Two hundred twenty-one participants were divided into two groups: one group at low risk (n?=?185) and the other at high risk (n?=?36) for pre-eclampsia. The two groups were compared with respect to shear wave velocity (SWV) of the placenta. Use of SWV as a predictor of pre-eclampsia was also investigated by creating a receiver operating characteristic (ROC) curve. The ROC curve was used to set a cutoff SWV value for predicting pre-eclampsia. The SWV of the high-risk group was significantly higher than that of the low-risk group (p < 0.001). Thirteen participants developed pre-eclampsia after SWV measurements, and the SWVs of these participants were significantly higher than those of participants in who pre-eclampsia did not develop. The cutoff value and area under the ROC curve were 1.188 m/s and 0.9118, respectively. Placental elasticity was significantly increased even before the onset of pre-eclampsia onset and, thus, may be a parameter used to predict the onset of pre-eclampsia.     

Comparison of high-power pain threshold ultrasound therapy with local injection in the treatment of active myofascial trigger points of the upper trapezius muscle

Unalan H, Majlesi J, Aydin FY, Palamar D. Comparison of high-power pain threshold ultrasound therapy with local ?njection in the treatment of active myofascial trigger points of the upper trapezius muscle.

Objective

To compare the effects of high-power pain threshold ultrasound (HPPTUS) therapy and local anesthetic injection on pain and active cervical lateral bending in patients with active myofascial trigger points (MTrPs) of the upper trapezius muscle.

Design

Randomized single-blinded controlled trial.

Setting

Physical medicine and rehabilitation department of university hospital.

Participants

Subjects (N=49) who had active MTrPs of the upper trapezius muscle.

Interventions

HPPTUS or trigger point injection (TrP).

Main Outcome Measures

Visual analog scale, range of motion (ROM) of the cervical spine, and total length of treatments.

Results

All patients in both groups improved significantly in terms of pain and ROM, but there was no statistically significant difference between groups. Mean numbers of therapy sessions were 1 and 1.5 in the local injection and HPPTUS groups, respectively.

Conclusions

We failed to show differences between the HPPTUS technique and TrP injection in the treatment of active MTrPs of the upper trapezius muscle. The HPPTUS technique can be used as an effective alternative to TrP injection in the treatment of myofascial pain syndrome.     

Neck Muscle Stiffness Quantified by Sonoelastography is Correlated with Body Mass Index and Chronic Neck Pain Symptoms

This study aimed to quantify neck muscle stiffness in the normal population with ultrasound elastography. We applied the acoustic radiation force impulse technique and measured shear wave velocities (SWVs) as representative values. The mean ± standard deviation values of SWV in 20 healthy volunteers were 2.09 ± 0.45, 1.21 ± 0.30, 1.12 ± 0.17 and 0.97 ± 0.10 m/s for the trapezius, levator scapulae, scalene anterior and sternocleidomastoid muscles, respectively. The SWV values of the four muscles significantly differed (Kruskal-Wallis test, p < 0.001). The SWV values for the trapezius muscle correlated with body mass indexes (Pearson's correlation, p = 0.034). Subjects with chronic neck pain symptoms had significantly stiffer trapezius muscle (Mann–Whitney U test, p = 0.008). This study demonstrated the technique and feasibility of quantifying neck muscle stiffness using acoustic radiation force impulse elastography and shear wave velocity detection. Further study is necessary to evaluate its diagnostic power in assessing various neck muscle diseases.     

The effect of manual pressure release on myofascial trigger points in the upper trapezius muscle

Sustained manual pressure has been advocated as effective treatment for myofascial trigger points (MTrPs). This study aimed to investigate the effect of manual pressure release (MPR) on the pressure sensitivity of latent MTrPs in the upper trapezius muscle using a novel pressure algometer. Subjects (N=37, mean age 23.1±3.2, M=12, F=23) were screened for the presence of latent MTrPs in the upper trapezius muscle (tender band that produced referred pain to the neck and/or head on manual pressure). Subjects were randomly allocated into either treatment (MPR) or control (sham myofascial release) groups. The pressure pain threshold (PPT) was recorded pre- and post-intervention using a digital algometer, consisting of a capacitance sensor attached to the tip of the palpating thumb. There was a significant increase in the mean PPT of MTrPs in the upper trapezius following MPR (P<0.001), but not following the sham treatment. Pressure was monitored and maintained during the application of MPR, and a reduction in perceived pain and significant increase in tolerance to treatment pressure (P<0.001) appeared to be caused by a change in tissue sensitivity, rather than an unintentional reduction of pressure by the examiner. The results suggest that MPR may be an effective therapy for MTrPs in the upper trapezius.
