A Feasibility Study of SSVEP-Based Passive Training on an Ankle Rehabilitation Robot

Table 1

Result of conducting combined ankle movement tasks.

Subject	S1	S2	S3	S4	S5
Number of accordant task	20	18	16	17	18
Success rate	100%	90%	80%	85%	90%
ITR (bits/min)	24	16.5	11.5	13.8	16.5

Note. Two kinds of tasks, one for combined DF and PF training, and the other for combined INV and EV training. The total number of motion intentions requested to identify for every subject is 20. The duration for robot to judge the motion intention of subjects is 5 s. The number of flickering circles representing the motion intention of subjects was 4.
