Sham Comparator
AOT + MI group
Control group
The AOT + MI group was shown a video (4 minutes) in which a subject (matched for age, sex, and limb affected) performed, in third person view, quadriceps concentric contractions for 2 minutes and isometric contractions for 2 minutes. The video contained visual elements indicating the maximality of the effort. After both concentric and isometric movement video the subjects performed a MI session (1 minute in length each), in which they were asked to imagine in first person the action previously observed in the video.
The control group was shown a video of landscapes (4 minutes in length). Halfway through and at the end of the video they were asked to imagine what they had just seen for 1 minute.
