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

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.

Intervention / Treatment

Experimental: Mobiderm; MOBIDERM® autofit : auto-adjustable compression stocking

Device: MOBIDERM® autofit : auto-adjustable compression stocking; The experimental protocol will require 2 visits during usual reduction phase performed at the hospital (5 days of hospitalization). Visit 1 will be performed the first day of hospitalization and will consist of inclusion visit and some evaluations (lymphoscintigraphy, edema volume, cutaneous characteristics). Between visit 1 (D1) and visit 2 (D3), patients will wear Mobiderm Autofit continually. Visit 2 will be performed the third day of hospitalization and will consist of evaluations (lymphoscintigraphy, edema volume, cutaneous characteristics, satisfaction survey).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change from baseline extraction rates at 3 days after wearing MOBIDERM	Assess the difference of extraction rate (%) in different areas (ankle, upper and lower middle third of the leg, knee, calf) by lymphoscintigraphy performed at D1 and D3 after wearing MOBIDERM®	Day : 3

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change of vascular lymphatic activity between D1 and D3	Assess change of vascular lymphatic activity based on qualitative data (activity YES/NO ; quality of activity : usual - semi usual - unusual) obtained during dynamic acquisition of lymphoscintigraphy from baseline to D3	Day : 3
Change of lymphatic vascular flow between D1 and D3	Assess change of amplitude vascular flow : important - medium- weak ; and of flow velocity : normal, slow, inexistent from baseline to D3	Day : 3
Change on lymphatic system between D1 and D3 : short term effect	Assess change on lymphatic system from baseline to D3 (short term effect) , based on quantitative data : number of lympho node fixation ; and qualitative data: lympho node fixation intensity : important - medium - low ; tortuous appearance of the lymphatic vessels : YES/NO ; presence of collateral : YES/NO ; presence of dermal reflux : YES/NO ; presence of popliteal ganglion : YES/NO.	Day : 3
Change on lymphatic system between H2 and H4 : immediate effect	Assess change on lymphatic system from baseline to 2 and 4 hours : immediate effect, based on quantitative data : number of lympho node fixation ; and qualitative data: lympho node fixation intensity : important - medium - low ; tortuous appearance of the lymphatic vessels : YES/NO ; presence of collateral : YES/NO ; presence of dermal reflux : YES/NO ; presence of popliteal ganglion : YES/NO.	Hours : 2 and 4
Lymphedema volume reduction between D1 and D3	Leg perimeters (cm) of 7 part of leg will be measured (ankle, patella, +10cm +20cm +30cm and -10cm -20cm and -30cm of patella). Based on truncated cone formula, volume (mL) of each leg will be calculated. These volumes will be compared between D1 and D3 in order to assess lymphedema volume reduction.	Days : 1 and 3
Skin condition evolution between D1 and D3	Skin condition will be assessed by cutaneous ultrasound scan (skin thickness (mm) , skin echogenicity (hypoechogenicity - isoechogenicity, hyperechogenicity) , oedema distribution in the dermis (superficial dermis - deep dermis - overall of dermis -hypodermis and dermis) performed on 3 areas : ankle, leg and thigh. Skin condition evolution will be assessed at D1 and D3.	Days : 1 and 3
Cutaneous suppleness between D1 and D3	Cutaneous suppleness evolution is assessed with a cutometer. Cutaneous suppleness is described by skin elasticity, elastic capacity and viscoelasticity. Cutometer measurements are expressed in millimetre (skin deformation, skin relaxation, skin extensibility) and will be presented as quantitative data.	Days : 1 and 3
Number of type of serious and non-serious Adverse Device Effects	Number and type of serious and non-serious Adverse Device Effects (ADE) will be reported during the study	Day : 3
Satisfaction regarding MOBIDERM	Satisfaction is measured by a satisfaction questionnaire wrote specifically for the study. This questionnaire is focused on positioning the product, comfort, esthetic and global satisfaction.	Day : 3
