Clinical,ultrasound,elastography and bioimpedance changes after radial extracorporeal shock wave therapy in patients with lipedema: A prospective within-patient study

Abstract

Background

Lipedema is an adipose disorder associated with multiple impairments. Conservative treatments remain the mainstay of management, yet evidence regarding the effects of physical therapies on clinical, imaging, and body composition outcomes is limited. Radial extracorporeal shock wave therapy (rESWT) has been proposed as a non-invasive therapeutic option, although its impact is not fully established.

Methods

This was a prospective, longitudinal, within-patient study conducted in women with clinically diagnosed lipedema. One lower limb was treated with radial extracorporeal shock wave therapy (rESWT), whereas the contralateral limb served as an internal control. A total of 16 patients were initially assessed, of whom 12 completed the full follow-up and were included in the final analysis. rESWT was applied over six sessions (two sessions per week) using standardized parameters. Clinical outcomes (LEFS, EQ-5D, SF-36 Physical Function, and IPAQ) were assessed at baseline, 6 weeks, and 3 months. Ultrasound and elastography were used to evaluate subcutaneous tissue thickness and stiffness at predefined leg and thigh sites, while segmental bioimpedance analysis assessed body composition and fluid distribution. Longitudinal changes were analyzed using mixed-effects models.

Results

Significant improvements were observed in functional capacity, quality of life, and physical activity levels at both 6 weeks and 3 months compared with baseline (p < .05). In contrast, no statistically significant changes were detected in ultrasound-derived tissue thickness, elastography measurements, or bioimpedance parameters over time, and no significant differences were detected between treated and control limbs within the constraints of the available sample size.

Conclusions

rESWT was associated with meaningful clinical and functional improvements in patients with lipedema, despite the absence of detectable changes in tissue thickness, stiffness, or body composition. These findings suggest that the benefits of rESWT may be mediated through symptom modulation and functional adaptation rather than structural tissue modification, supporting its role as part of conservative, symptom-oriented treatment strategies in lipedema.
