Abstract:

Study examined the value of using American Spinal Injury Association (ASIA) motor subscores rather than the total ASIA motor score to predict functional abilities as measured using motor Functional Independence Measure (FIM) scores. Discharge data from subjects with traumatic spinal cord injury (SCI) included in the National SCI Database were used in the analysis. Results showed that the use of separate ASIA upper-extremity and lower-extremity motor scores instead of a single ASIA motor score improved prediction of motor FIM scores.
