Extracorporeal Shock Wave Therapy in Lower Extremity Lymphedema
Efficacy of Extracorporeal Shock Wave Therapy (ESWT) in Lower Extremity Lymphedema: A Randomized Controlled Trial
Přehled studie

Detailní popis
Lower extremity lymphedema results from impairment of the lymphatic system and is characterized by progressive tissue fibrosis, chronic limb swelling, recurrent infections, and reduced quality of life. Complex Decongestive Therapy (CDT), recommended by the International Society of Lymphology, remains the gold-standard treatment. Despite adherence to CDT, many patients continue to experience persistent symptoms and functional decline, underscoring the need for effective adjunctive interventions.
Extracorporeal Shock Wave Therapy (ESWT) is a non-invasive modality that has shown potential benefits in reducing fibrosis and improving lymphatic function. While its efficacy has been reported in upper extremity lymphedema, evidence in lower extremity lymphedema remains limited.
This single-center, prospective, randomized, double-blind, placebo-controlled trial will be conducted at the Department of Physical Medicine and Rehabilitation, Gazi University Faculty of Medicine. Patients currently in CDT Phase 2 (maintenance phase) will be randomly assigned in a 1:1 ratio to receive either active ESWT or sham ESWT, using stratified randomization by lymphedema stage. All participants will continue standard maintenance therapy - compression garments, skin care, and exercise - throughout the study. ESWT will be applied to fibrotic tissue regions and periinguinal and peripopliteal lymph node areas using the EMS Swiss DolorClast® device, with 3,000 impulses per session at 20 Hz and 2 bar. The primary outcome is change in lower extremity circumferential measurements and limb volume. Secondary outcomes include skin and subcutaneous tissue thickness assessed by ultrasonography, pain intensity measured by the Visual Analogue Scale (VAS), lymphedema-specific quality of life evaluated by the LYMQOL-Leg, and functional status assessed by the Lower Extremity Functional Scale (LEFS). All outcomes will be assessed at baseline, immediately after treatment, and at one-month follow-up.

Experimentální: ESWT + CDT Maintenance
Participants in this group receive active Extracorporeal Shock Wave Therapy (ESWT) applied to fibrotic tissue regions of the affected lower extremity and periinguinal and peripopliteal lymph node areas, in addition to standard CDT maintenance therapy.
ESWT will be administered twice weekly for a total of five sessions.
|
Radial shock wave therapy will be applied using the EMS Swiss DolorClast® device.
Each session will consist of 3,000 impulses delivered at 20 Hz and 2 bar using a 40 mm applicator, targeting fibrotic tissue regions and periinguinal and peripopliteal lymph node areas.
ESWT will be administered twice weekly for five sessions

Falešný srovnávač: Sham ESWT + CDT Maintenance
Participants in this group receive sham ESWT applied to the same anatomical regions using identical device positioning and application procedures, but with only non-energized impulses delivered.
Standard CDT maintenance therapy will be continued throughout the study.
|
Sham ESWT will be applied with identical positioning and session duration as the active ESWT group.
Only non-energized impulses will be delivered, ensuring participant blinding.
Sham ESWT will be administered twice weekly for five sessions.
