Medical applications for SOZO


Early detection and ongoing monitoring of treatment

Heart failure

Fluid status monitoring for patients living with HF

Physical therapy

Fluid status and tissue composition analysis to monitor progress

More about SOZO

SOZO measures 256 unique data points over a wide spectrum of frequencies from 3 kHz to 1000 kHz to provide a detailed fluid and tissue analysis, including the L-Dex score, to establish patient baselines and monitor trends over time. The FDA-cleared, CE-marked and ARTG-listed digital health platform aids in the early detection of secondary lymphedema, provides fluid status for patients living with heart failure, and can be used to monitor and maintain overall health.

Hardware and software

The core component is a physical medical device with hand and foot plates (SOZOtouch and SOZOstep), typically attached to a pedestal and controlled with an Android tablet pre-installed with the SOZOapp. All user accounts, patient records, measurement data, and other calculated measures and trends are stored in the proprietary and secure MySOZO cloud.
