Classification
Supplemental - Highly Recommended: Stroke
Short Description of Instrument
Purpose: This scale assesses neurologic deficit severity following pediatric ischemic stroke.
 
Overview: The PSOM is a composite of clinical and radiographic information and a detailed neurologic examination. The measure was published in 2000.
 
Time: Varies depending on the examination results for the 115 test items
 
Psychometric Properties: The PSOM has demonstrated reliability and validity. It has been used in several neonatal/ childhood stroke studies to assess neurological deficit severity.
Scoring
Scoring: The neurologic examination of the PSOM contains 115 test items ordered developmentally in the areas of behavior, mental status, cranial nerves, motor functions, sensory function, cerebellar function, and gait function. At the completion of the examination, a deficit severity score ranging from 0 (no deficit) to 2 (severe deficit) is assigned for each of five spheres: right sensorimotor (including motor, visual, hearing, and somatosensory function), left sensorimotor, language production, language comprehension, and cognitive and behavioral performance. The patient is assigned an overall Deficit Severity Score of normal, mild, moderate, or severe for each assessment, based on the combination of scores in the individual spheres of the PSOM.
 
 
Scoring for Pediatric Stroke Outcome Measure (PSOM)
Adapted from (deVeber et al., 2000)
 
Good, Normal: Score = 0 in all five spheres
 
Good, Mild deficit: Score = 0.5 in one sphere only
 
Poor, Moderate deficit: Score = 0.5 in two, three, or four spheres; Score = 1 in one sphere and 0.5 in one sphere; Score = 1 in one sphere only
 
Poor, Severe deficit: Score = 0.5 in all five spheres; Score = 1 in one sphere plus 0.5 in two spheres; Score = 1 in at least two spheres; Score = 2 in at least one sphere
 
0 = No impairment, normal function; 0.5 = minimal to mild impairment, normal function; 1 = moderate impairment, decreased function; 2 = severe impairment, loss of function.
Right sensorimotor, left sensorimotor, language expressive, language comprehensive, and cognitive and behavior.
