Abstract

Study design: Retrospective analysis of prospectively collected data.

Objective: Central cord syndrome (CCS) is reported to have better outcomes than other cervical lesions, especially for ambulation and bladder recovery. However, a formal comparison between patients with CCS and other incomplete cervical spinal cord injuries (iCSCI) is lacking. Aim of the study is to investigate the neurological and functional outcomes in patients with or without CCS.

Setting: European Multicenter Study.

Methods: Data following SCI were derived from the European Multicenter Study about Spinal Cord Injury Database. CCS was diagnosed based on a difference of at least ten points of motor score in favour of the lower extremities. Patients were evaluated at 30 days, 6 months and 1 year from injury. The neurological and functional data were collected at each time point based on the International Standards for Neurological Classification of Spinal Cord injury (ISNSCI) and Spinal Cord Independence Measure (SCIM). Patients were selected with a matching procedure based on lesion severity, neurological level of injury (NLI) and age. Evaluation of the outcomes was performed by means of two-way Anova for repeated measures.

Results: The matching produced 110 comparable dyads. At all time points, upper extremity motor scores remained lower than lower extremity motor scores in CCS compared with iCSCI. With regard to daily life independence, both cohorts achieved comparable improvements in self-care sub-scores between T0 and T2 (6.6 ± 6.5 in CCS vs 8.2 ± 6.9 in iCSCI, p = 0.15) but this sub-score was significantly lower in CCS compared with iCSCI (3.6 ± 5.2 in CCS vs 7.3 ± 7.0 in iCSCI at T0, 13.7 ± 6.2 vs 16.5 ± 5.7 at T2), while the other sub-scores were comparable.

Conclusions: In contrast to previous reports, people with CCS have poorer outcomes of self-care ability compared with iCSCI.
