This prospective multi-center nonrandomized interventional clinical trial was conducted at eight level-1 trauma centers in North America with specialized units for SCI care. Twenty-seven patients presenting with motor-sensory complete SCI (AIS grade A) had catheters inserted for up to 7-days post-injury for CSF drainage and SCPP augmentation. Mean arterial pressure, intrathecal pressure (ITP), SCPP, ITP waveform morphology, and CSF drainage volume were collected hourly. Neurologic assessments were repeated at 6-months post-injury to determine if AIS grade conversion\/improvement had occurred. Hemodynamic measures associated with the outcome of being an AIS grade \u201cconverter\u201d or \u201cnon-converter\u201d were compared. Of the 27 AIS A participants at baseline, 8 experienced neurologic recovery reflected by AIS grade conversion at 6-month follow-up (converters); 19 remained AIS A (non-converters). Converters were characterized by a higher ITP, lower SCPP, greater CSF drainage volume, and a more pulsatile ITP waveform morphology than nonconverters. In patients with AIS A SCI, AIS grade conversion at 6 months was associated with a specific pattern of hemodynamic measures that we hypothesize reflect a complete decompression and restoration of CSF flow in the subarachnoid space at the injury site. These metrics may provide guidance and\/or targets for future studies on the management of acute SCI.<\/jats:p>","DOI":"10.1177\/2689288x261455160","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T07:54:20Z","timestamp":1780991660000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Characterizing
