Investigation of Pain Relief Bias in Grasping Movements

Abstract

The action of holding hands is said to be effective in touching used in nursing. However, the action of grasping the hand includes the action of“ being grasped ”in addition to the action of“ grasping ”. Therefore, in this study, we focused on the “ grasping ” motion and investigated to what extent the sensation of pain changes depending on the presence or absence of the motion. It is also said that there is a threshold for pain, and that the act of grasping the hand delays the onset of pain. However, since the ultimate threshold is unknown, we investigated how the“ grasping ”motion changes the pain threshold.
