Physical Therapy

Secondary lymphedema is a leading post-treatment complication for many cancer patients.

However, with early detection, appropriate interventions and ongoing monitoring, the symptoms of lymphedema can be managed, and in some cases, even reversed.1

Tracking patient progress

SOZO, the world’s most advanced, noninvasive bioimpedance spectroscopy (BIS) device, offers physical therapists a fast, simple, noninvasive way to measure the impact of physical therapy on healthy patients following treatment. SOZO assesses multiple fluid compartments and body composition at the same time—without labor-intensive dilution or underwater weighing techniques2—to quantify improvements in skeletal-muscle mass or decreases in fat mass.

Monitoring overall health

Based on the knowledge that BMI is an imperfect measure of body fat, a team of researchers hypothesized that greater body fat percentage, independent of BMI, would be associated with increased health risks. In a cohort study3, they examined associations between BMI and percent fat with mortality. The study found that having a higher percent body fat or a low BMI was independently associated with reduced survival. This “obesity paradox” indicates that overweight and moderately obese patients with certain chronic illnesses actually outlive thinner people with the same conditions.3

As a more direct and accurate measurement of body composition, SOZO is recommended as an effective tool for monitoring overall health.4
