To investigate (1) the effect of spray and stretch versus control on reducing postneedling soreness of 1 latent myofascial trigger point (MTrP) and (2) whether higher levels of psychological distress are associated with increased postneedling pain intensity.
A 72-hour follow-up, single-blind randomized controlled trial.
University community.
Healthy volunteers (N=70; 40 men, 30 women) aged 18 to 36 years (mean age, 21±4y) with latent MTrP in 1 upper trapezius muscle.
All subjects received a dry needling application over the upper trapezius muscle. Then, participants were randomly divided into 2 groups: an intervention group, which received spray and stretch over the needled trapezius muscle, and a control group, which did not receive any intervention.
Visual analog scale (at postneedling, posttreatment, and 6, 12, 24, 48, and 72h after needling), pressure pain threshold (at preneedling, postneedling, and 24 and 48h after needling). Psychological distress was evaluated by using the Symptom Checklist-90-Revised.
Repeated-measures analysis of variance demonstrated a significant interaction between group and time (F3,204.8=3.19; P<.05; ηp(2)=.04) for changes in postneedling soreness. Between-group differences were significant only immediately after intervention (P=.002), and there were no differences found between groups after 6 hours of the intervention (P>.05). Repeated measures of covariance showed that none of the psychological covariates affected these results. Somatization, anxiety, interpersonal sensitivity, and hostility were significantly correlated (P<.05) with postneedling pain intensity. Repeated-measures analysis of variance did not show a significant effect of spray and stretch on mechanical hyperalgesia (F2.6,175=1.9; P=.131; ηp(2)=.02).
The spray and stretch had a short-term (<6h) effect in reducing postneedling soreness of a latent MTrP. Pressure pain threshold did not significantly change after spray and stretch. Psychological factors are related to postneedling pain.
调查（1）喷雾拉伸与对照组对减轻1个潜在肌筋膜触发点（MTrP）针刺后疼痛的效果，以及（2）较高水平的心理困扰是否与针刺后疼痛强度增加相关。
一项72小时随访的单盲随机对照试验。
大学社区。
年龄在18至36岁（平均年龄21±4岁）、一侧上斜方肌存在潜在MTrP的健康志愿者（N = 70；40名男性，30名女性）。
所有受试者均接受对上斜方肌的干针治疗。然后，参与者被随机分为两组：干预组，接受对针刺的斜方肌进行喷雾拉伸；对照组，不接受任何干预。
视觉模拟量表（针刺后、治疗后以及针刺后6、12、24、48和72小时）、压力痛阈（针刺前、针刺后以及针刺后24和48小时）。使用症状自评量表-90修订版评估心理困扰。
重复测量方差分析显示，针刺后疼痛变化在组间和时间上存在显著交互作用（F3,204.8 = 3.19；P <.05；ηp(2)=.04）。组间差异仅在干预后立即显著（P =.002），干预6小时后组间无差异（P >.05）。重复测量协方差分析表明，心理协变量均未影响这些结果。躯体化、焦虑、人际敏感和敌对与针刺后疼痛强度显著相关（P <.05）。重复测量方差分析未显示喷雾拉伸对机械性痛觉过敏有显著影响（F2.6,175 = 1.9；P =.131；ηp(2)=.02）。
喷雾拉伸对减轻潜在MTrP针刺后疼痛有短期（<6小时）效果。喷雾拉伸后压力痛阈无显著变化。心理因素与针刺后疼痛相关。
