Does Improvement in American Spinal Injury Association Impairment Scale Grade Correlate With Functional Recovery in All Patients With a Traumatic Spinal Cord Injury?

OBJECTIVE: The aim of the study is to determine what improvement on the American Spinal Injury Impairment Scale correlates with functional status after a traumatic spinal cord injury. DESIGN: We performed an observational cohort study, analyzing prospective data from 168 patients with traumatic spinal cord injury admitted to a single level 1 trauma center. A multivariable analysis was performed to assess the relationship between functional status (from the Spinal Cord Independence Measure) at 1-year follow-up and American Spinal Injury Impairment Scale grade (baseline and 1-yr follow-up), while taking into account covariables describing the sociodemographic status, trauma severity, and level of neurological injury. RESULTS: Individuals improving to at least American Spinal Injury Impairment Scale grade D had significantly higher Spinal Cord Independence Measure score compared with those not reaching American Spinal Injury Impairment Scale D (89.3 ± 15.2 vs. 52.1 ± 20.4) and were more likely to reach functional independence (68.5% vs. 3.6%), regardless of the baseline American Spinal Injury Impairment Scale grade. Higher final Spinal Cord Independence Measure was more likely with an initial American Spinal Injury Impairment Scale grade D (ß = 1.504; 95% confidence interval = 0.46-2.55), and a final American Spinal Injury Impairment Scale grade D (ß = 3.716; 95% CI = 2.77-4.66) or E (ß = 4.422; 95% CI = 2.91-5.93). CONCLUSIONS: Our results suggest that reaching American Spinal Injury Impairment Scale grade D or better 1 yr after traumatic spinal cord injury is highly predictive of significant functional recovery, more so than the actual improvement in American Spinal Injury Impairment Scale grade from the injury to the 1-yr follow-up.

Do all patients with functional motor-incomplete (AIS-D) traumatic spinal cord injury need specialized inpatient functional rehabilitation? A prospective observational cohort study proposing clinical criteria for home-based rehabilitation after acute care.

CONTEXT/OBJECTIVE: Functional motor-incomplete AIS-D traumatic spinal cord injury (tSCI) represents an important growing population in neuro-traumatology. There is thus an important need for establishing strategies to optimize SCI rehabilitation resources. This study aims at proposing eligibility criteria to select individuals who could be discharged home (home-based rehabilitation) after acute care following an AIS-D tSCI and investigate its impact on the long-term functional status and quality of life (QOL), as compared to transfer to inpatient functional rehabilitation (IFR) resources. DESIGN: An observational prospective cohort study. SETTING: A single Level-1 specialized trauma center. PARTICIPANTS: 213 individuals sustaining an AIS-D tSCI. INTERVENTIONS: Home-based rehabilitation based on clinical specific criteria to be assessed by the acute care team. OUTCOME MEASURES: Functional status and QOL as assessed by the Spinal Cord Independence Measure version 3 and WHOQOL-BREF questionnaire one year following the injury, respectively. RESULTS: A total 37.9% of individuals fulfilled proposed criteria for home-based rehabilitation after acute care. As expected, this group was significantly younger, experienced lesser comorbidities and acute complications, and showed higher motor and sensory function compared to the IFR group. Home-rehabilitation was associated with a higher long-term functional status, physical and psychological QOL, when accounting for relevant confounding factors after an acute AIS-D tSCI. There was no readmission due to failure of home-based rehabilitation. CONCLUSION: Home-based rehabilitation in selected individuals sustaining an acute AIS-D tSCI is a safe and interesting strategy to optimize the long-term outcome in terms of functional recovery, physical and psychological QOL, as well as to optimize inpatient rehabilitation resources. The proposed eligibility criteria can be used by the acute care team to select the optimal discharge orientation in this important subpopulation.
