Methodology Eligible individuals with SCI who are admitted to CVAMC with pelvic region pressure ulcers will be assigned to a pulsatile lavage treatment group or to a second non-intervention control group. A comprehensive assessment methodology will be employed to characterize pressure ulcer healing. All study participants will be assessed at routine intervals using objective measurement techniques. Statistical analysis of inter-group differences will allow the efficacy of pulsatile lavage for pressure ulcer healing to be established. Forty subjects will be enrolled in the study.
