ObjectivesTo introduce a new measure of disability weighted for the neurologic deficit in patients with spinal cord lesions and to examine the effect on the instrument of being in rehabilitation.DesignDevelopment of instrument and preliminary comparative before-after study.SettingSpinal department in a rehabilitation hospital in Israel.ParticipantsSeventy-nine patients with spinal cord lesions.InterventionsPatients were repeatedly assessed during rehabilitation with the American Spinal Injury Association Impairment Scale (AIS) to measure neurologic motor impairment and with the Spinal Cord Independence Measure (SCIM-II) to measure disability. Scores of the 2 assessments were combined to create the Spinal Cord Injury Ability Realization Measurement Index (SCI-ARMI).Main Outcome MeasuresA preliminary formula for the calculation of SCI-ARMI using the individual patients' SCIM-II and AIS motor scores and changes in SCI-ARMI values through rehabilitation.ResultsThe highest observed SCIM-II scores at patients' AIS level correlated highly with the AIS motor scores (r=.96, P<.01). A regression performed for this linear relationship resulted in a preliminary SCI-ARMI formula. The calculated SCI-ARMI values improved during rehabilitation irrespective of patient age, gender, lesion level, or lesion severity (P<.001).ConclusionsThe preliminary version of the SCI-ARMI can be used to assess quantitatively changes in functional ability, isolating them from the effect of neurologic changes.
