Perception of surface pressure applied to the hand

摘要

The study aimed to determine the relationship between the physical magnitude and the subjective perception of applied pressure, and to determine discomfort and pain thresholds. Free modulus magnitude estimation of the subjective pressure level was made on three points: on the finger, the palm and the thenar area. The pressure was judged to be higher at the thenar point than at the finger and palm points. The slopes of the linear functions (log magnitude estimates as function of log pressure) were 0.66, 0.78 and 0.76 for the finger, palm and thenar points respectively.
