Abstract
Study design:
Prospective multi-center cohort study.
Objectives:
To compare the neurological and functional recovery between tetraplegic Brown-Séquard-plus syndrome (BSPS) and incomplete tetraplegia (non-BSPS).
Setting:
European Multicenter Study of Human Spinal Cord Injury (EM-SCI).
Methods:
BSPS was defined as a traumatic incomplete spinal cord injury (SCI) with ipsilateral weakness and contralateral loss of pinprick sensation at neurologic levels C2–T1. Acute (0–15 days) and chronic phase (6 or 12 months) were assessed for the American Spinal Injury Association (ASIA) sensory scores, upper extremity motor scores and lower extremity motor scores. Furthermore, chronic phase scores of all Spinal Cord Independence Measure (SCIM) II items were analyzed. Differences in neurological and functional outcome between BSPS patients and non-BSPS patients were calculated using Student's t-tests and Wilcoxon signed rank tests.
Results:
Out of 148 tetraplegic patients, 30 were diagnosed with BSPS. Patients with an ASIA impairment scale (AIS) B were significantly (P<0.001) more identified in non-BSPS patients (25%) compared with BSPS patients (3%), respectively. After 12 months, the median scores for sphincter management of the bladder for both BSPS and non-BSPS patients were 15. Both 25 and 75% quartile median scores were 15 for BSPS patients and 12 and 15 for non-BSPS patients (P<0.02). Except for the difference in bladder function, no significant differences were identified in other SCIM II subitems and ASIA motor or sensory scores between BSPS and non-BSPS patients when stratified for injury severity by excluding AIS B patients.
Conclusion:
Compared with incomplete tetraplegic patients, patients with cervical BSPS have a similar neurological and functional recovery when matched for the AIS.
