Physiological Study to Assess Mechanism of Action of MOBIDERM® in Lower-limb Lymphedema Patients

MOBIDERM® demonstrated his interest through clinical studies on the treatment of lower or upper limb lymphedema (Mestre et al 2017; Quéré et al. 2014). This CE (Conformity European)-marking device is well established both in ambulatory and hospitalisation. Nevertheless, the mechanism of action of this device had never been confirmed and no experimental clinical studies had been performed. The hypothesis is that the MOBIDERM system creates a pressure differential between the contact zone underneath the foam cubes composing the system and their surrounding area, leading to a shear effect on the subcutaneous tissues treated.

The aim of this study is thus to assess the mechanism of action of MOBIDERM on the lymphatic system by evaluating quantitative and qualitative effects of this medical device on lymphatic system, oedema volume and cutaneous parameters in 10 lymphoedema patients during their hospitalisation for reduction phase.

Inclusion Criteria:

• Primary or secondary lower limb lymphedema of stage 2 or 3 according to the criteria defined by International Society of Lymphology

Exclusion Criteria:

• Pregnant or breastfeeding patient
• Childbearing age patient without contraception
• Intolerance to Mobiderm or known allergy to the components used
• Evolutive lower limb infection
• Acute lower limb inflammation
• Dermatological ailment oozing from the treated limb
• Severe medical condition that may interfere with the proper conduct of the study
• Advanced diabetic microangiopathy
• Limb arteritis stage III or IV
• Decompensated heart failure
• Involvement in another clinical study
• Patient mentally incapable of understanding the nature, objectives and possible consequences of the study and / or refusing to submit to the constraints of this trial
