Outcomes

Primary Outcomes

Mechanical Pain Threshold

Time Frame: immediately after intervention

Mechanical Pain Threshold will be measured using custom-made weighted pinprick stimuli as a set of seven pinprick mechanical stimulators with fixed stimulus intensities (flat contact area of 0.2mm diameter) with forces of 8, 16, 32, 64, 128, 256, and 512mN.
