| dc.description.abstract | This thesis describes a study on a new active assistance in robotic rehabilitation in a haptic virtual environment for post-stroke patients. The novelty of this active assistance system lies in that the assistance is directly rendered on the result of a task performing. Active assistance will generally raise the confidence level of patients in performing a rehabilitation exercise. However, an overly high assistance level may induce cognitive fatigue with patients and thus decreases their motivation of performing a rehabilitation exercise. This thesis hypothesizes that a proper active assistance can improve the performance of a rehabilitation exercise, but will not reduce the motivation of patients in doing rehabilitation exercise. However, due to the difficulty in obtaining a proper number of patients for the experiment, the study turned to healthy people. Accordingly, a revised hypothesis is that active assistance on healthy people does not improve the task performance and not reduces the motivation of healthy people. In this thesis, first, a test-bed with the haptic virtual environment was designed and constructed. The test-bed included a simple task – i.e., following a predefined circle trajectory. Then, a statistical experiment was designed and an experiment was conducted on the test-bed. The experimental results test the hypothesis successfully. The main contributions of this thesis are: (1) the development of a new active assistance system for rehabilitation in a virtual environment and (2) the experimental study on the motivation of healthy people with the developed active assistance system. A care must, however, be taken that the experiment was conducted on healthy people and the conclusion drawn from the study may not be valid on patients. | |
