简要总结
The objective is to estimate the effects on pain thresholds of a painful mechanical stimulus on the upper trapezius compared to a painful electrical stimulus and a diffuse noxious stimulus using the cold water hand immersion test.
详细描述
The mechanical stimulus produced in manual therapy (MT) techniques elicits neurophysiological responses within the peripheral and central nervous system responsible for pain inhibition. Almost all types of MT elicit a neurophysiological response that is associated with the descending pain modulation circuit. But it has not been demonstrated whether this inhibition occurs through a conditioned pain modulation mechanism induced by painful mechanical stimulation that is carried out with manual therapy techniques.

结局指标
主要结局
Change from Baseline in Tibialis Anterior Pressure Pain Threshold (PPT) to immediate post-conditioning stimulus
时间窗: At baseline and immediately after the conditioning stimulus
PPTs will be assessed on the dominant side over the tibialis anterior muscle using a digital algometer (Wagner instruments, Greenwich, CT, USA). Participants will be instructed to say "stop" when the pressure sensation becomes painful. The average of 3 assessments on the tibialis anterior of the dominant side will be performed for analysis. The algometer pressure for assessment will be gradually increased at a rate of 1kg/second. Data will be collected in kg/cm2.
