SCR-LIP-000043 · Claim · machine-readable JSON →
Lipedema has a distinctive quantitative sensory testing (QST) signature in the affected limb — isolated lowered pressure pain threshold and raised vibration detection threshold with spared thermal thresholds — yielding high diagnostic accuracy (PVTH-score AUC 0.958).

- Non-obese lipedema patients show a distinctly altered quantitative sensory testing profile with high diagnostic potential — Dinnendahl et al. (2024) ✓ verified — consistent · cross sectional · 2024 · risk of bias: moderate · reading confidence: high
“Pressão é mediada por fibras C/Aδ; vibração por fibras Aβ → o padrão alterado sugere envolvimento seletivo destes subgrupos de fibras, com inflamação sistêmica e hormonal descartadas como causadores principais (não há sensibilização da mão); inflamação local clássica também improvável (ausência de h”
Dinnendahl/Bertsch; only PPT-down and VDT-up of 13 parameters; pattern in thigh, absent in hand - Relationship of the tissue stiffness measured using shear wave elastography with the pain threshold and quality of life of patients with lipedema: A cross-sectional study — Ozturk et al. (2025) ✓ verified — refining · cross sectional · 2025 · reading confidence: high
Cross-sectional study with 71 participants directly measuring pain thresholds and tissue mechanical properties in lipedema versus controls; provides mechanistic insight into pain (pressure hyperalgesia independent of BMI) but does not eluci

Gaps & caveats
Single study; mechanism of the pattern not established; needs independent replication.
