Relative level of transferred performance (cross-modal transfer, CMT; except VIS→VIS and ACU→ACU transfer to the same modality) from the previous to the current condition for the height of the foot over the obstacle (height), the variation ratio (VR) of the ankle (AN), knee (KN) and hip (HI) angle curves, the root mean square of rectus femoris (RF), biceps femoris (BF), tibialis anterior (TA) and gastrocnemius medialis (GM) muscles, the duration of the whole step over the obstacle (Step t) and the duration of the swing phase over the obstacle (Swing t). Conditions as for Table 1. Significant loss of mean CMT (P < 0.05) is printed in bold.
