OBJECTIVE: To evaluate potential pain cutoff scores reflecting mild, moderate,
and severe pain in the spinal cord injury (SCI) population and determine the
relationship between the derived cutoff scores and both psychosocial and
functional outcome measures. DESIGN: Retrospective analysis. SETTING: SCI Model
Systems. PARTICIPANTS: Persons (N=6096; age >18y) with traumatic SCI (American
Spinal Injury Association Impairment Scale [AIS] grades
A-D; injured in
1973-2008). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Numeric rating
scale (NRS) of pain severity (11 points), NRS of pain interference (5 points),
Satisfaction With Life Scale, Patient Health Questionnaire-9, Craig Handicap
Assessment and Reporting Technique Short-Form (CHART-SF), motor component of the
FIM (M-FIM), and employment. RESULTS: The best set of pain severity cutoff points
are 1 to 3, 4 to 6, and 7 to 10. This was validated by randomly assigning sample
members to 2 groups and replicating. There were significant differences in all
outcomes as a function of pain severity grouping, although they explained little
of the variance in M-FIM and CHART-SF Physical Independence scale scores.
Neurologic status differed significantly between pain groups, with incongruence
between pain severity and interference in people in the AIS grade D group, who
reported the greatest pain interference and least pain severity. CONCLUSION:
Pain severity can be categorized into groups that reflect pain interference. These
groupings differentiate psychosocial well-being better than activity limitations.
They do not provide a comprehensive pain assessment, for which pain type,
location, and interference are likely to be necessary.
