Background

Aim

..to examine the contribution of superficial and deep pain when using flat or spherical probes when applying pain mechanical pressure.

Methods

• Healthy volunteers
• Fixed mechanical pressure (4 kg)
• Two different probe heads
• With/without light superficial anesthesia

Results

n = 33 healthy volunteers (F =16)
