ASIA Impairment Scale

A method of assessing the degree of motor and sensory impairment in spinal cord injured patients. The assessment is based on an examination of the perineum and anus, i.e., on the S4-S5 level of the spinal cord. Grade: A – Complete: No motor or sensory function; Grade B – Incomplete, sensory function is intact, but motor function is absent below and including the S4-S5 level; Grade C – Incomplete, motor function is preserved below the neurological level and more than half of the primary muscles have a muscle grade test of less than 3; Grade D – Incomplete: Motor function is preserved and at least half of the muscles below the S4-S5 level have a muscle grade test of 3 or better; and Grade E – Normal.
