Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower. The area that needs a high sensitivity like the palm of the <span>hands(especially the fingertips), face</span>, and tongue should be the one with lowest two-point discrimination.
In this report, a<span>nterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm. </span>
