BackgroundChronic pain is more prevalent among women; however, the majority of standardized pain
drawings are often collected using male-like androgynous body representations.ObjectiveThe purpose of this study was to assess whether gender-specific and high-resolution
three-dimensional (3D) body charts facilitate the communication of pain for women.MethodsUsing mixed-methods and a cross-over design, female patients with chronic pain were
asked to provide detailed drawings of their current pain on masculine and feminine
two-dimensional (2D) body schemas (N=41, Part I) or on female 2D and 3D high-resolution
body schemas (N=41, Part II) on a computer tablet. The consistency of the drawings
between body charts were assessed by intraclass correlation coefficient (ICC) and
Bland-Altman plots. Semistructured interviews and a preference questionnaire were then
used to obtain qualitative and quantitative responses of the drawing experience.ResultsThe consistency between body charts were high (Part I: ICC=0.980, Part II: ICC=0.994).
The preference ratio for the masculine to feminine body schemas were 6:35 and 18:23 for
the 2D to 3D female body charts. Patients reported that the 3D body chart enabled a more
accurate expression of their pain due to the detailed contours of the musculature and
bone structure, however, patients also reported the 3D body chart was too human and
believed that skin-like appearance limited ‘deep pain’ expressions.ConclusionsProviding gender-specific body charts may facilitate the communication of pain and the
level of detail (2D vs 3D body charts) should be used according to patients’ needs.
