Pain Inhibitory Effects of Other Pain Induced by Mechanical Pressure Compared to Electrical Stimulation and Cold Water.

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

healthy male or female between 18 and 65 years
Free of pain and with no history of chronic pain

Exclusion criteria

Pregnant or having given birth within the last year

Treatment and study plan

Conditioning stimulus

Other

Pain stimulus on non-dominant side

Primary outcomes

Change from Baseline in Tibialis Anterior Pressure Pain Threshold (PPT) to immediate post-conditioning stimulus

Time frame: 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.
