Only one study examined the effect of active stand training using the body weight support treadmill system on cardiovascular function among individuals with complete SCI. Harkema et al. (2008) found that after 80 sessions (60 minutes/session; 5x/week) of active stand training, individuals with complete cervical SCI demonstrated increased resting blood pressure and improvements in the cardiovascular responses to standing.

There is level 4 evidence (from 1 pre-post study: Harkema et al. 2008) that 80 sessions of active stand training improves cardiovascular control such as response to orthostatic stress after cervical SCI.
