Sub-Hertz Analysis of Viscoelasticity of Limbs in Patients With Lymphedema

August 13, 2025 updated by: Antonio J. Forte, Mayo Clinic
Researchers are trying to validate the use of ultrasound sub-hertz analysis of viscoelastisty (SAVE) method to monitor tissue-fluid dynamics and stage disease severity in patients diagnosed with lymphedema.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Affected (Lymphedema)
Subjects affected lymphedema extremity will have elastic and viscoelastic parameters collected by ultrasound procedure
Diagnostic test: Ultrasound Procedure
Ultrasound technique that uses a compression device integrated with ultrasound imaging to perform in vivo ramp-and-hold uniaxial creep-like test on upper extremity lymphedema (UEL) in vivo.
Active Comparator: Unaffected (Control)
Subjects unaffected extremity will have elastic and viscoelastic parameters collected by ultrasound procedure
Diagnostic test: Ultrasound Procedure
Ultrasound technique that uses a compression device integrated with ultrasound imaging to perform in vivo ramp-and-hold uniaxial creep-like test on upper extremity lymphedema (UEL) in vivo.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Viscoelasticity parameters with lymphedema as obtained using the SAVE method
Time Frame: Baseline
Defined as the difference in viscoelastic parameters between the arm affected with lymphedema and the unaffected extremity (affected minus unaffected) using the sub-hertz analysis of viscoelasticity method
Baseline
