Physiological arousal accompanying postural responses to external perturbations after stroke

Neuromuscular control of standing balance is known to be impaired after stroke (Garland et al. 2009). Response to surface translations have characterized the postural reactions of people post-stroke as being asymmetrical favoring the non-paretic leg (Marigold et al. 2004; van Asseldonk et al. 2006), accompanied by muscle activation which is delayed, and of decreased amplitude, in the paretic limb with poor intra-limb muscle coordination (Badke and Duncan 1983; Marigold and Eng 2006). In particular, the plantarflexor muscles in people post-stroke demonstrate impaired responses to external perturbations (Pollock et al.
