Resumen:
Background. Expanded distribution of pain is considered a sign of
central sensitization (CS). The relationship between recording of
symptoms and CS in people with knee osteoarthritis (OA) has been poorly
investigated.
Objective. The aim of this study was to examine whether the area of pain
assessed using pain drawings relates to CS and clinical symptoms in
people with knee OA.
Design. This was a cross-sectional study.
Methods. Fifty-three people with knee OA scheduled to undergo primary
total knee arthroplasty were studied. All participants completed pain
drawings using a novel digital device, completed self-administration
questionnaires, and were assessed by quantitative sensory testing. Pain
frequency maps were generated separately for women and men. Spearman
correlation coefficients were computed to reveal possible correlations
between the area of pain and quantitative sensory testing and clinical
symptoms.
Results. Pain frequency maps revealed enlarged areas of pain, especially
in women. Enlarged areas of pain were associated with higher knee pain
severity (r(s) = .325, P<05) and stiffness (r(s) = .341, P<.05), lower
pressure pain thresholds at the knee (r(s) = -.306, P<.05) and
epicondyle (r(s) = -.308, P<.05), and higher scores with the Central
Sensitization Inventory (r(s) = .456, P<.01). No significant
associations were observed between the area of pain and the remaining
clinical symptoms and measures of CS.
Limitations. Firm conclusions about the predictive role of pain drawings
cannot be drawn. Further evaluation of the reliability and validity of
pain area extracted from pain drawings in people with knee OA is needed.
Conclusion. Expanded distribution of pain was correlated with some
measures of CS in individuals with knee OA. Pain drawings may constitute
an easy way for the early identification of CS in people with knee OA,
but further research is needed.
