Abstract
In this paper, we show a method to model coordinated joint range of motion (ROM) of the thumb with subjective discomfort by exhaustively testing various postures. Coordinated joint ROM was modeled by capturing twelve exercises for four adults without any hand disabilities. Posture candidates were then generated for the discomfort experiment by uniformly sampling each subject’s ROM. Each subject was asked to answer if they felt it difficult to retain that posture for 10 s owing to pain or fatigue. The collected data from four subjects were converted into a discomfort possibility map.
