Lymphoedema research invitation

Would you like to be involved in lymphoedema research? You are invited to participate in a study on the new ImpediMed SOZO device. 

What is the purpose of this study?

When Lymphoedema is present, fluids build up within the tissues, resulting in the swelling of the affected limb. This can be assessed by measuring the resistance to low frequency currents that have been passed through the limb. The L-Dex® U400 and SOZO devices assess Lymphoedema using this method. If you have lymphoedema, you may already be familiar with having L-Dex® readings taken by your lymphoedema therapist. The purpose of the study is to compare the new SOZO device with the L-Dex® U400 to determine its validity and reliability. We are looking for both individuals with lymphoedema of the arm/s and/or leg/s and individuals without lymphoedema to participate in this study.

What will I be required to do? 

Participants will be asked to attend a 60-minute appointment at the MQ Health Lymphoedema Clinic (Suite 301, 1 Talavera Road Level 3, Clinic Building, Faculty of Medicine and Health Sciences, Macquarie University). During the appointment, a research assistant will discuss your medical history and take measurements of your height, weight, arm circumference, limb volume and L-Dex® readings in sitting, standing and lying positions with the U400 and SOZO devices. These measurements do not pose any health risks and will be relatively quick and painless.

How do I participate?

If you are interested in participating, or would like more information about the study, please contact Louise Koelmeyer via telephone (+61 2 9850 2358) or e-mail (
