This combination of systems proved to be very successful in regaining movement for the patient. In fig. 3A, the different movements are shown with the different muscle contractions. The dot plots show the success rate for virtual and real arm movement; it shows that the movement is above the possibility of chance. The virtual arm was shown to have quicker response, but this is probably due to the lack of strength in the muscles. The patient was given the task of drinking coffee which involved reaching and grasping; this test had success 11 out of 12 times. Fig. 4 shows this action along with the time it took to complete each stage of this function. For this task, the system was turned off to see if any function remained, but showed no movement, thus proving the success in movement is due to the two-part system.
