Changes in functional independence after inpatient rehabilitation in patients with spinal cord injury: A simultaneous evaluation of prognostic factors.

Objective: This study aimed to investigate the improvements of functional independence following inpatient rehabilitation and compare those improvements between different levels and severities of Spinal Cord Injury (SCI). Prognostic factors affecting the patient's outcomes were also studied.

Settings: Rofeideh Rehabilitation Hospital.

Outcome measures: Spinal Cord Independence Measure version III (SCIM III), and Functional Independence Measure (FIM).

Method: In this retrospective cohort study, 180 patients with SCI were enrolled to record their functional independence upon admission and discharge, and the changes were compared between different levels and severities of injury using non-parametric tests. The prognostic factors of outcomes were studied by generalized estimating equation (GEE) analysis.

Results: The independence changes were significant for all the severities (American Spinal Injury Association Impairment Scale (AIS)) and levels of injury except for the patients with AIS A and B at upper cervical levels (P < 0.05). The level of injury, AIS, Length of Stay (LOS), and pressure ulcer had a significant prognostic value on patient's outcomes. Furthermore, there was a significant difference between different levels of injury with the same AIS grade in functional improvement (P < 0.05), while there was a significant difference between AIS groups with the same level of injury only at upper and middle cervical lesions (P < 0.05).

Conclusion: Recording the values of functional independence before and after rehabilitation in individuals with SCI can help clinicians approximately expect the outcomes of future patients. Moreover, a deeper study of the prognostic factors can provide a more logical expectation of rehabilitation outcomes.
