Prevalence of orthostatic hypotension determined by consensus statement (AAS/AAN, 1996; Freeman et al., 2011) by Cervical, High Thoracic, and Low Cord levels and severity of injury (determined by ISNCSCI (Kirshblum et al., 2011). Orthostatic hypotension is defined as a drop in systolic blood pressure (≥20 mmHg) and/or diastolic blood pressure (≥10 mmHg) within 3 minutes of assumption of an upright position. Percentage of individuals that experienced orthostatic hypotension is indicated with shades of red; percentage of individuals that did not experience orthostatic hypotension is indicated with shades of gray. Among cervical SCI, prevalence of orthostatic hypotension was significantly lower in individuals with AIS A classification (5%) compared with AIS B (14%; p = 0.007) and AIS C (13%; p = 0.002)
