Evaluation of Involvement of Subjects in Rehabilitation Exercises using Physiological Signals

摘要

Active participation of patients in exercise is an important factor in maintaining rehabilitation programs. In this study, an adaptive algorithm called partially ordered set master (POSM), and a traditional algorithm (increment/decrement one level at a time) that change the difficulty levels of rehabilitation tasks adaptively for each individual have been evaluated. A small working group of 20 healthy subjects are asked to play a fruit- assisted rehabilitation system with the use of these two adaptive methods. The difficulty of the game is dynamically changed according to the performances (score) of the subjects with these two algorithms. The physiological signals, performance (score), and subjective reports (arousal/valence) are used to evaluate these two algorithms in terms of engaging the subjects.
