Abstract: We asked whether abdominal binding improves cardiorespiratory function in individuals with cervical spinal cord injury (SCI). 13 participants with chronic SCI (C 5-C 7) and 8 able-bodied controls were exposed to varying degrees of elastic abdominal compression (unbound [UB], loose-bound [LB], and tight-bound [TB]) while seated. In SCI, TB increased vital capacity (14%), expiratory flow throughout vital capacity (15%), inspiratory capacity (21%), and maximal expiratory mouth pressure (25%). In contrast, TB reduced residual volume (-34%) and functional residual capacity (-23%). TB increased tidal and twitch transdiaphragmatic pressures (∼45%), primarily by increasing the gastric pressure contributions. TB increased cardiac output (28%), systolic mitral annular velocity (22%), and late-diastolic mitral annular velocity (50%). Selected measures of cardiorespiratory function improved with LB, but the changes were less compared to TB. In able-bodied, changes were inconsistent and always less than in SCI. In conclusion, abdominal-binding improved cardiorespiratory function in low-cervical SCI by optimising operating lung volumes, increasing expiratory flow, enhancing diaphragmatic pressure production, and improving left-ventricular function. © 2011 Elsevier B.V.
