  1. Condition 1 was the coordination movement for the dominant (non-paretic) ankle from dorsiflexion 10° to plantarflexion 10° and simultaneously moving the non-dominant (paretic) ankle from plantar flexion 10° to dorsiflexion 10° in healthy and stroke subjects; Condition 2 was the coordination movement for the non-dominant (paretic) ankle from dorsiflexion 10° to plantarflexion 10° and simultaneously moving the dominant (non-paretic) ankle from plantar flexion 10° to dorsiflexion 10° in healthy and stroke subjects
