More sensitive and accurate measurements

REGIONAL APP is the dedicated application to analyze the bioimpedance data of 10 anatomical body regions based on the innovative REGIONAL BIA model.

Regional analysis (or Regional BIA) is the most advanced solution to analyze specific body segments as it considers the musculoskeletal system for each anatomical area.

Regional Bia

The evolution from a geometric model to an anatomical configuration.

The traditional “Segmental model” (Segmental BIA) simplifies body segments into cylinders (geometric model).

It is known however, that this approximation does not reflect positively in the prediction of the LBM (Lean Body Mass) since, for example, it does not consider the junction areas between limbs and trunk, which contribute significantly to the bioimpedance of the individual limbs. As Muscles are conductive tissues, they extend way over the joints between limbs and trunk, describing a model (anatomical configuration) that is different from the skeletal structure.

The new REGIONAL BIA model, developed by AKERN, overcomes the geometric assumptions of current distribution, which is the reference for the segmental model.

The innovative REGIONAL BIA analysis technique, available with the BIA 101 BIVA PRO sensor, focuses on the real musculoskeletal architecture of the anatomical districts analyzed, allowing for a most accurate LBM (Lean Body Mass) assessment of each individual body district.

More accurate estimations

Lean Soft Tissue Mass is the fat-free and bone-mineral-free compartment that includes muscle and other components such as skin, tendons and connective tissues and is the largest contributor to body mass. The new REGIONAL BIA model, validated vs DEXA, provides a precise Lean Soft Tissue (LST) estimate of 10 anatomical regions and improves sensitivity to minimal changes.
