ABSTRACT
Rehabilitation is important to LD recovery. Most current rehabtraining activities rely on the labor-intensive process which requires the continuous assistance from a physical therapist. The physical therapist helps the patient to repeat many actions by monitoring and correcting the patient’s gestures. This kind of rehab-training is very costly due to the signifi cant involvement of physical therapists
or nurses. Recently, the robot-assisted rehab-training scheme was invented. Figure 1 shows an example of robot-aided rehab-training machine called KineAssist, which requires less involvement of therapists than the conventional approach due to its intelligent patient motion assistance [5]. Such a machine can hold the patient whenever he or she loses body balance. The physical therapist can set up the exercise contents and assist the patient to achieve certain goals (such as grabbing a ball). However, the robot-assisted rehab-training still needs many efforts from the physical therapists due to the complexity of the exercises and lack of enough intelligence within the machine.
