Abstract：
UNASSIGNED: To assess the effects of 5 different durations of electro-dry needling (EDN) on asymptomatic individuals\' pain response after repeated noxious thermal stimuli.
UNASSIGNED: Randomized, non-controlled intervention trial.
UNASSIGNED: University laboratory.
UNASSIGNED: Asymptomatic participants (N=50) were recruited for the study and randomized into 5 groups. There were 33 women with an average age of 26.8 (±4.8) years. To participate in the study, individuals had to be between the ages of 18 and 40, free of any musculoskeletal injury which prevented participation of daily activities, and not pregnant or trying to become pregnant.
UNASSIGNED: Participants were randomly assigned to receive 5 different durations of EDN: 10, 15, 20, 25, and 30 minutes. To perform the EDN, 2 monofilament needles were inserted lateral to the lumbar spinous processes of L3 and L5 on the right. Needles were left in situ with electrical stimulation at a frequency of 2 Hz and an amplitude which resulted in a 3 to 6 out of 10 intensity pain rating by the participant.
UNASSIGNED: The change in the magnitude of pain in response to repetitive heat-pulses before and after the EDN procedure.
UNASSIGNED: There was a significant reduction in the magnitude of pain in response across the groups after EDN (F(1,42)=94.12, P<.001, ƞp2=.691). However, the interaction between time and group was not significant (F(4,42)=1.019, P=.409, ƞp2=.088), indicating that no duration of EDN was superior to another in reducing temporal summation.
UNASSIGNED: This study suggests that in asymptomatic individuals, performing EDN beyond 10 minutes does not provide any additional benefits in the reduction of the magnitude of pain in response to thermal nociceptive stimuli. Additional study in symptomatic populations is required for generalizability in clinical settings.

摘要：
■评估5种不同持续时间的电干针刺（EDN）对重复有害热刺激后无症状个体\'疼痛反应的影响。
■随机化，非对照干预试验。
■大学实验室。
■招募无症状参与者（N=50）进行研究，并随机分为5组。有33名女性，平均年龄为26.8（±4.8）岁。参加研究,个人必须在18至40岁之间，没有任何肌肉骨骼损伤，这阻碍了日常活动的参与，而不是怀孕或试图怀孕。
■参与者被随机分配接受5种不同持续时间的EDN：10、15、20、25和30分钟。要执行EDN，在右侧L3和L5的腰椎棘突外侧插入2根单丝针。在2Hz的频率和振幅下将针留在原位,这导致参与者在10个强度疼痛评级中的3至6个。
■在EDN程序之前和之后，响应于重复热脉冲的疼痛幅度的变化。
■EDN后，各组的疼痛反应程度显着降低（F（1,42）=94.12，P<.001，p2=.691）。然而,时间与组之间的交互作用不显著(F(4,42)=1.019,P=.409,p2=.088),表明EDN的持续时间在减少时间总和方面没有优于另一个。
■这项研究表明，在无症状的个体中，进行超过10分钟的EDN在减少对热伤害性刺激的疼痛程度方面没有任何额外的益处。需要在有症状人群中进行额外的研究，以便在临床环境中具有普遍性。
