Chronic neck pain (CNP) may be associated with latent myofascial trigger points (MTrPs) in the levator scapulae (LS), which can be treated with ischemic compression (IC) and dry needling (DN). Variables and elastography changes are evaluated to compare the short-term efficacy of two treatments with DN.
A randomized clinical trial is conducted with 80 participants in two groups: the DN group ( = 40) and IC group ( = 40). The duration is 12 weeks, and mechanical heterogeneity index, pressure pain threshold (PPT), and pain intensity are measured at baseline, immediately after, 48 h after, and one week after treatment.
Statistically significant changes were immediately observed between the two groups: PPT decreased in the DN group ( = 0.05), while it increased in the IC group. At 48 h and one week after treatment, these values increased in the DN group and remained higher than in the IC group. The heterogeneity index improved in both groups but more significantly in the DN group than in the IC group.
In subjects with CNP who had latent plus hyperalgesic MTrPs in the LS muscle, DN outperformed IC in PPT, pain intensity, and mechanical heterogeneity index at 48 h and one week after initiating therapy.
慢性颈部疼痛（CNP）可能与肩胛提肌（LS）中的潜在肌筋膜触发点（MTrP）有关，缺血性按压（IC）和干针疗法（DN）可用于治疗。评估相关变量和弹性成像变化，以比较DN两种治疗方法的短期疗效。
对80名参与者进行一项随机临床试验，分为两组：DN组（n = 40）和IC组（n = 40）。疗程为12周，在基线、治疗后即刻、治疗后48小时和治疗后一周测量机械异质性指数、压力疼痛阈值（PPT）和疼痛强度。
两组之间即刻观察到统计学上的显著变化：DN组PPT降低（P = 0.05），而IC组PPT升高。在治疗后48小时和一周时，DN组这些值升高且仍高于IC组。两组的异质性指数均有所改善，但DN组比IC组更显著。
在LS肌肉中存在潜在加痛觉过敏MTrP的CNP患者中，在开始治疗后48小时和一周时，DN在PPT、疼痛强度和机械异质性指数方面优于IC。
