Abstract
Background: Lipedema is a chronic condition characterized by abnormal deposition of subcutaneous adipose tissue, leading to pain. The lack of internationally recognized diagnostic criteria complicates the characterization of pain. Physiological parameters such as pain pressure threshold (PPT) represent promising prognostic markers for diagnosing lipedema, yet they remain understudied. This study aimed to evaluate the reliability and validity of two pain pressure measurements, PPT and the hand-held sphygmomanometer (HHS) in lipedema. Methods: A total of 28 adult females diagnosed with lipedema were recruited. Both PPT, using a digital algometer, and HHS, using a manual aneroid HHS, were performed to assess pain in the lower limbs. The testing was performed in a standing position with PPT and HHS placed on the calf. Intraclass correlation coefficient (ICC) and coefficient of variation (CV) were employed to assess the within session reliability, while the validity between PPT and HHS was analyzed using R2 in a linear regression model. Results: The results showed excellent reliability for both PPT and HHS, with ICC indicating high consistency (ICC = 0.93 to 0.97) and CV showing acceptable scores (CV = 3.62% to 9.06%). In addition, good validity between PPT and HHS was also observed (R2 = 0.69 to 0.74), suggesting that HHS can be a reliable alternative to PPT for pain assessment in lipedema. Conclusion: These findings have important clinical implications, as they expand the knowledge of pain characterization in people with lipedema, potentially aiding in diagnostic refinement. In addition, a cost-effective and accessible method for assessing pain was examined (i.e., HHS), showing promising findings and providing an objective method to help diagnose lipedema.
