Left panel: Training at home for a participant in the track group. The training system consisted of a laptop computer (A) (in this instance, showing 1:17 min/s into a participant-selected pause from tracking), an ankle electrogoniometer brace (B), a web camera (C), a single-button control box (in participant's hands, not shown), and a wireless modem (D). Right panel: Telecommunication setup at therapist's location. The therapist could see the participant's tracking performance in one window. Simultaneously in another window, with the participant's camera directed on the ankle, the therapist also could see the actual ankle movement. With the therapist's camera directed on the therapist, the participant could see the therapist. Audio was transmitted in both directions.
