Abstract
BACKGROUND: Lipedema is a chronic disorder characterized by symmetrical and disproportionate fat accumulation, pain, and easy bruising, often resistant to conventional treatments. Functional dysmetria (FD), a maladaptive neuromotor response linked to epigenetic stress, has been proposed as a relevant contributor to pain in lipedema. OBJECTIVE: This retrospective observational study aimed to evaluate whether correcting FD through the radioelectric asymmetric conveyer (REAC) technology Neuropostural Optimization (NPO) protocol can reduce pain in patients with lipedema, using a sham-controlled design. METHODS: In this retrospective observational study, 83 consecutive women with stage 2-5 lipedema underwent both sham and real NPO procedures during a single session. Pain intensity was measured using the visual analog scale (VAS) immediately after each procedure. Statistical analyses were performed using paired t-tests with effect sizes (Cohen's dz) and 95% confidence intervals. RESULTS: Baseline pain was uniformly high (mean 7.41 ± 0.53), with some pre-sham values reaching 10/10. Pain reduction was observed exclusively after real NPO and not after sham. Sham NPO induced no significant changes, whereas real NPO yielded a mean pain reduction exceeding 3.5 VAS points across all stages (mean change -3.65 ± 0.62; 95% CI: -3.79 to -3.51; Cohen's dz = 5.88, 95% CI: 4.85-6.92; p < 0.0001). CONCLUSIONS: These findings suggest that correction of FD by REAC NPO provides rapid and clinically meaningful analgesic effects in lipedema patients, addressing an upstream neuropsychomotor dysfunction that may contribute to disease progression. However, given the retrospective single-center design and absence of long-term follow-up, these conclusions are limited to the short-term effects observed. Further multicenter and longitudinal studies are warranted to confirm these results and evaluate long-term outcomes.
