“…However, sympathectomized patients, who lack sympathetic vascular innervation, but participate in normal physical activity, do not exhibit the structural or functional vascular adaptations typically observed in the SCI model (Eisenach et al 2002; Hashmonai and Kopelman 2003). In addition, previous studies in SCI have demonstrated that vascular adaptations are partly reversible by electrical stimulation training of the inactive paralyzed legs in SCI (de Groot et al 2005; Hopman et al 2002; Thijssen et al 2007b).…”
