摘要
目的:通过对颈肩炵痛受试者的上斜方肌静力牵伸、等长收缩以及静力牵伸加等长收缩,观察其肌电图特征性变化
以及主观疼痛感觉变化,探索不同干预缓解肌肉疼痛、降低肌肉紧张的最低重复次数和时间,比较三种方法的优劣,
以确定最小有效干预剂量和较佳干预方案。
方法:招募20例颈肩疼痛受试者,随机抽取12例为ー组,共抽取3次,分别对上斜方肌进行静力牵伸、等长收缩以及
静力牵伸加等长收缩干预,每组干预时间间隔15d,对上斜方肌进行肌电图检測和干预前后的疼痛视党模拟量表
(VAS)衡量主观疼痛感觉。
结果:静力牵伸、等长收缩以及静力牵伸加等长收缩干预后,颈肩部主观疼痛感显著降低(P<0.01、P<0.05和P<
0.01);静力牵伸和静力牵伸加等长收缩干预后,右侧上斜方肌表面肌电图(sEMG)静息绝对值和相对值有显著降低
(P<0.01);等长收缩干预后右侧上斜方肌sEMG静息绝对值和相对值无显著性差异(P>0.05);静力牵伸加等长收
缩和静力牵伸比等长收缩干预更能有效的降低右侧上斜方sEMG静息绝对值和相对值(P<0.05)。
结论:三种运动干预方案均能起到缓解受试者颈肩部疼痛的即时效果,静力牵仲和静力羍仲加等长收缩能够有效的
缓解颈肩部疼痛患者肌紧张。

Abstract
Objective: To de ect the changes of EMG characteri and AS ine for the patients upper trapezius with
neck-shoulder complaints after stretching and isometric-contraction training. To identify thethe minimum ef ec
tive dose and the best intervention by detecting and comparing the minimum repeated times and time of three
methods alleviating muscle pain and reducing muscle tension
Method: We recruited twenty patients with neck-shoulder complaints, from whom 12 subjects were randomly
selected for 3 times. The upper trapezius for each patient was given stretching, isometric contraction and
stretching-isometric contraction training, respectively, with 15 days interval. Before and after intervention, EMG
examination and VAS test were performed
Result: After the intervention, VAS index decreased significantly(P<0.01, P<0.05 and P<0.01). In the right side
of the upper trapezius, the resting absolute value and relative value of SEMG were decreased significantly(<
0.01) after stretching or stretching-isometric contraction, while no significant difference after isometric contraction
