Training program and study design. Four stroke persons participated in a training program based on directional and plantarflexion static exertions. Mobility parameters (gait velocity and Timed Up and Go test results) were evaluated at every session at baseline (E1 to E7), during the treatment (T1 to T23) and upon withdrawal (E8 to E13) and one other time 2 months later (E14). Muscle activity patterns were evaluated during static directional exertions in sessions identified in yellow and italics at baseline (E1, E4, E7), upon withdrawal (E8, E10, E13) and at follow-up (E14). During the intervention period, MVEs were measured at the beginning of each week. Participants were asked to perform eight controlled static exertions in the eight directions and plantarflexion exertion during the first session and twelve during the second and third sessions of each week at an increasing level of exertion each week
