Fig 2 An individual with SCI in a specialized testing chair that allows for passive changes in position from sitting to supine and a rapid return to sitting for the orthostatic challenge. Legs are strapped in to avoid spasms during position changes. A chest strap may be used to prevent trunk motion during the maneuver. The person has an automatic blood pressure/heart rate cuff attached to the arm that records data each minute for specified intervals.

Fig 3 Boxplots of SBP (left panel), DBP (center panel), and heart rate (right panel) in sitting at rest and supine positions for patients with cervical injuries (maroon, n=271), patients with high thoracic injuries (green, n=46), and patients with low thoracic injuries (blue, n=33). All parameters in all positions significantly differed (P<.03) over the neurologic levels. Abbreviations: BP, blood pressure; bpm, beats per minute; HR, heart rate.

Fig 4 Boxplots of SBP (left panel), DBP (center panel), and heart rate (right panel) in sitting at rest and supine positions for patients with (light gray, n=35) and without (dark gray, n=315) central cord syndrome. Supine SBP and heart rate in all positions significantly differed between groups (P<.006). Abbreviation: BP, blood pressure.

Fig 5 Boxplots of SBP (left panel) and DBP (right panel) in the supine preorthostatic challenge and sitting postorthostatic challenge positions for patients with (n=75, light gray) and without (n=275, dark gray) orthostatic hypotension. Abbreviation: BP, blood pressure. Archives of Physical Medicine and Rehabilitation , DOI: ( /j.apmr ) Copyright © 2012 American Congress of Rehabilitation Medicine Terms and Conditions
