Adaptive conjunctive cognitive training (ACCT) in virtual reality for chronic stroke patients: a randomized controlled pilot trial

摘要

Experimental protocol and set-up. The protocol lasted 18 weeks in total, 6 weeks of training, and 3-months follow-up period. The set-up of the EG in the hospital consisted of a desktop computer, a Microsoft Kinect and two wristbands with reflective markers that are worn by the patient. A Tobii EyeTracker T120 tracked the eye movement of the patient during the training. The Kinect detects the reflective markers and transposes the movement of the patient's real arms onto the virtual arms of the avatar in the training scenarios. The patients are seated at a table, and the three training scenarios ( Complex Spheroids, Star Constellations, and Quality Controller) are shown on the screen always in the same order. Besides the automated adaptive difficulty mechanism and the embodied training, the system incorporates further principles of neurorehabilitation including the provision of multisensory feedback, feedback of results, variable and structured practice as well as promoting the use of the paretic limb.
