Effects of push and support translation on EMGs. A–D, Representative examples of EMG responses to push and support translation in 3 selected muscles of the limb performing the stance at the moment of disturbance. A, B, Effects of rightward push during stance of the right limb (A, Push in) and during stance of the left limb (B, Push out; Test 1). C, D, Effects of inward (C, Trans in) and outward (D, Trans out) limb translation during stance (Test 3). Shaded area indicates the stance phase of the right limb (Limb-R) in A, C, D and of the left limb (Limb-L) in B, in the step preceding disturbance and in the step with disturbance. Limb (Y): mediolateral limb position. Other designations as in Figure 5.
