• Proposes a pain classification scheme with 2 major categories: neuropathic and musculoskeletal.
  • Designed to help with the standardization of pain terminology used in the SCI population.
  • Pain is categorized by pain location and distribution, as related to level of spinal injury (e.g. above level, at level or below level). This information is combined with a classification of the subject’s SCI pain.
  • Neurologic pain – classifications:
    1. SCI pain
    2. Transition zone pain
    3. Radicular pain
    4. Visceral pain
  • Musculoskeletal pain – classifications:
    1. Mechanical spine pain
    2. Overuse pain

Clinical Considerations

  • This tool has the most reliable (within (κ=0.68) and between (κ=0.66) raters), standardized system for classifying pain in people with SCI using well defined terminology.
  • The interview format improves utility for those with limited hand function.
  • There is a high initial patient burden (considerable time is required to complete the assessment); however, follow up sessions require less time.

ICF Domain

Body Function ▶ Sensory Function

Administration

  • Clinician-administered but could also be completed by the patient.
  • The patient identifies the worst pain problem on a body diagram and indicates whether pain worsens with activity, position or change of position or light touch. This procedure is repeated for second worse pain etc.

Number of Items

2 categories of pain with 6 subcategories. Each subcategory has 3 items to classify pain.

Equipment

None

Scoring

Categorization is outlined in the table below (fill out with +, – or +).

Pain Category (major)

Pain Category (Specific)

Location

Related to activity

Affected by position

Worse with light touch

Neuropathic

SCI pain

Below injury in area without normal sensation

Neuropathic

Transition zone pain

At level of injury, bilateral

Neuropathic

Radicular Pain

At any dermatome level, usually unilateral, usually radiates

Visceral

In abdomen

Musculoskeletal

Mechanical spine pain

In back or neck, often bilateral

Musculoskeletal

Overuse pain

Often above injury in areas of normal sensation in an incomplete, can be below

+ yes, – no, + maybe

Languages

English

Training Required

No formal training required. However, knowledge of pain is beneficial.

# of studies reporting psychometric properties: 1

Interpretability

This classification system provides a nice summary table that makes it easy for clinicians to identify key problem areas expressed by the patient.

MCID: not stablished in SCI
MDC: not stablished in SCI
SRD: not stablished in SCI

Reliability

The strength of agreement between raters in categorizing pain problems was Moderate for both the method of reporting on questionnaire (K=0.68) and reporting in person (K=0.66).

(Cardenas et al. 2002)

Validity

Results of expert voting to determine Face Validity:

  • Valid and useful: 4%
  • Useful but requires more validation: 20 % Useful but requires changes/improvement then further validation: 52%
  • Not useful or valid for research in SCI: 25%
  • It was determined to be less valid and useful than both the Bryce-Ragnarsson Pain Taxonomy (BRPT) and the International Association for the Study of Pain (IASP) SCI Classification.

(Bryce et al. 2007)

Responsiveness

No values have been reported for the responsiveness of the Classification System for Chronic Pain for the SCI population.

Floor/Ceiling Effect

No values were reported for the presence of floor/ceiling effects in the Classification System for Chronic Pain in SCI for the SCI population.
