To determine the immediate effect of neural tension technique (NTT) on conditioned pain modulation in patients with chronic neck pain. A secondary objective was to determine the immediate effect of neural tensioner technique on pain intensity and cervical range of movement.
Randomized clinical trial.
University medical center.
Fifty-four patients with neck pain (13 males and 41 females; mean± SD age = 20.91 ± 2.64 years) were randomly allocated to two groups: NTT or sham technique.
Participants received a visual analog scale (VAS) and neck disability index (NDI) after inclusion. Conditioned pain modulation (CPM) and active cervical range of motion were measured before and after the intervention. Each subject received one treatment session.
The results of the analysis of variance revealed a significant effect for the group × time interaction only for CPM (F = 11.09, P = 0.002, ηp2 = 0.176). No significant interactions were found for the other measures (VAS [F = 1.719, P = 0.195, ηp2 = 0.031], pressure pain threshold C2 [F = 0.731, P = 0.398, ηp2 = 0.018], flexion [F = 0.176, P = 0.677, ηp2 = 0.003], extension [F = 0.035, P = 0.852, ηp2 = 0.001], lateral flexions [F = 0.422, P = 0.519, ηp2 = 0.008], and rotations [F = 1.307 P = 0.258, ηp2 = 0.024]). Regarding CPM, intergroup interaction differences were found postintervention (P = 0.002) with a high effect size (d = 0.98).
This study suggests that neural tension technique enhances immediate conditioned pain modulation in patients with chronic neck pain, but not pain intensity or cervical range of movement.
确定神经张力技术（NTT）对慢性颈痛患者条件性疼痛调制的即时影响。次要目的是确定神经张力器技术对疼痛强度和颈椎活动范围的即时影响。
随机临床试验。
大学医疗中心。
54 名颈痛患者（13 名男性和 41 名女性；平均年龄±标准差=20.91±2.64 岁）随机分为两组：NTT 或假技术。
纳入后，参与者接受视觉模拟评分（VAS）和颈部残疾指数（NDI）。在干预前后测量条件性疼痛调制（CPM）和主动颈椎活动范围。每位患者接受一次治疗。
方差分析结果显示，仅 CPM 的组×时间交互作用有显著影响（F=11.09，P=0.002，ηp2=0.176）。其他测量值未发现显著交互作用（VAS [F=1.719，P=0.195，ηp2=0.031]、C2 压痛阈值 [F=0.731，P=0.398，ηp2=0.018]、屈曲 [F=0.176，P=0.677，ηp2=0.003]、伸展 [F=0.035，P=0.852，ηp2=0.001]、侧屈 [F=0.422，P=0.519，ηp2=0.008]和旋转 [F=1.307，P=0.258，ηp2=0.024]）。关于 CPM，干预后发现组间交互作用差异（P=0.002），具有高效应量（d=0.98）。
本研究表明，神经张力技术可增强慢性颈痛患者即时条件性疼痛调制，但不能增强疼痛强度或颈椎活动范围。
