Mental practice protocol Prior to experimental sessions, the mental capacity of subjects to learn the imagery techniques will be tested by the Kinesthetic and Visual Imagery Questionnaire and a chronometric test. The Kinesthetic and Visual Imagery Questionnaire is an imagery assessment tool comprised of 10 items, each scored on a five-point ordinal scale, including the image clarity (visual dimension) and the sensations intensity (kinesthetic dimension) of body movements. Each item describes an action: (i) neck flexion/extension, (ii) shoulder shrugging, (iii) forward trunk flexion, (iv) forward shoulder flexion, (v) elbow flexion, (vi) thumb to finger tips, (vii) knee extension, (viii) hip abduction, (ix) foot external rotation, and (x) foot tapping. Subjects physically execute each movement and immediately afterwards imagine performing the same movement. A score of 5 corresponds to the highest clarity/intensity, and a score of 1 corresponds to the lowest clarity/ intensity (for a review, see Malouin et al., 2007). The Kinesthetic and Visual Imagery Questionnaire scores allowed the researcher to assess each participant's abilities and decide whether the subject was a suitable candidate for MP. Comparing actual and imagined movement times, the chronometric test determined the motor imagery ability of participants.
