Outcome

Type Measure Description Time frame Safety issue
Primary Lymphatic Activation Comparison of the change in the rate of lymphatic propulsion events from the pre-treatment values to the post-treatment values for both the affected and contralateral limbs using the investigational technique of near infrared-fluorescent (NIRF) imaging. Baseline and following a single treatment, an average of one hour
Primary Changes in Swelling - MoistureMeterD Comparison of the percent change in local tissue water from the pre-treatment values to the post-treatment values on the affected limb using MoistureMeterD. Baseline and following a single treatment, an average of one hour
Primary Changes in Swelling - Perometry Swelling in the affected and contralateral limb as assessed using local tissue water content Baseline and following a single treatment, an average of one hour
Primary Percent Change in Skin Thickness From Baseline to After Treatment. Skin changes on the affected and contralateral limb as assessed by skin thickness (Ultrasound). Baseline and following a single treatment, an average of one hour
Primary Incidence of Adverse Events Adverse events reported between treatment and the 24-hour follow-up 24-Hour Follow-Up
Primary Post-Treatment Functional Vessel Assessment Via Near Infrared-fluorescent (NIRF) Imaging Comparison of the number of subjects with an increase in vessels for both the affected and contralateral limbs via near infrared-fluorescent (NIRF) imaging. Baseline and following a single treatment, an average of one hour
Primary Projected Area or Extent of Dermal Backflow Via Near Infrared-fluorescent (NIRF) Imaging Comparison of the change in dermal backflow from the pre-treatment values to the post-treatment values as the sum of the volume of area for all locations for both the affected and contralateral limbs via near infrared-fluorescent (NIRF) imaging Baseline and following a single treatment, an average of one hour
Primary Swelling in the Affected and Contralateral Limb as Assessed Using: Perometry (LymphaTech 3D Scanner) Compare the percent of participants by arm demonstrating a decrease in limb volume for the affected and contralateral limbs via Perometry (LymphaTech 3D Scanner) Baseline and following a single treatment, an average of one hour
Primary Skin Changes on the Affected and Contralateral Limb as Assessed by: Skin Thickness (Ultrasound) Comparison of the percent of participants by arm demonstrating a decrease in thickness for each site, separating skin and subcutaneous changes, on the affected limb via Ultrasound Baseline and following a single treatment, an average of one hour
Primary Absolute Change in Skin Thickness From Baseline to After Treatment Skin Changes on the affected and contralateral limb as assessed by skin thickness (Ultrasound). Baseline and following a single treatment, an average of one hour.
