Graphesthesia is the ability to recognize writing on the skin purely by the sensation of touch. Graphesthesia is done in order to test for certain neurological conditions such as; lesions in brainstem, spinal cord, sensory cortex or thalamus. This activity allows the user to write single numbers on the palm with a toothpick. The patient provides a verbal response identifying the figure that was drawn. Loss of graphesthesia indicates either parietal lobe damage on the side opposite the hand tested or damage to the dorsal columns pathway at any point between the tested point and the contralateral parietal lobe.
