Ambulation following spinal cord injury and its correlates

Abstract

Objectives:To assess walking ability of spinal cord injury (SCI) patients and observe its correlation with functional and neurological outcomes.Patients and Methods:The present prospective, observational study was conducted in a tertiary research hospital in India with 66 patients (46 males) between January 2012 and December 2013. Mean age was 32.62 ± 11.85 years (range 16-65 years), mean duration of injury was 85.3 ± 97.6 days (range 14-365 days) and mean length of stay in the rehabilitation unit was 38.08 ± 21.66 days (range 14-97 days) in the study. Walking Index for spinal cord injury (WISCI II) was used to assess ambulation of the SCI patients. Functional recovery was assessed using Barthel Index (BI) and Spinal Cord Independence Measures (SCIM). Neurological recovery was assessed using ASIA impairment scale (AIS). We tried to correlate ambulatory ability of the patients with functional and neurological recovery.Results:Ambulatory ability of the patients improved significantly using WISCI II (P < 0.001) when admission and discharge scores were compared (1.4 ± 3.5 vs 7.6 ± 6.03). Similarly, functional (BI: 31.7 ± 20.5 vs 58.4 ± 23.7 and SCIM: 29.9 ± 15.1 vs 56.2 ± 20.6) and neurological recovery were found to be very significant (P < 0.001) when admission vs discharge scores were compared. Improvement in WISCI II scores was significantly correlated with improvement in neurological (using AIS scores) and functional status (using BI and SCIM scores) (P < 0.001).Conclusions:Significant improvement was seen in WISCI II, BI, and SCIM scores after in-patient rehabilitation. Improvement in WISCI II scores also significantly correlated with functional and neurological recovery.
