Summary

This study tests whether a wearable bioimpedance wristband (like a fitness tracker) helps people with severe obesity and knee osteoarthritis improve their body composition—gaining muscle and losing fat—before joint replacement surgery. All participants receive coaching on body composition, but half also use the wristband to track their progress. The goal is to see if the wristband leads to better changes in muscle and fat compared to coaching alone.

Active substance

InBody Band 2 (wearable bioimpedance wristband)

What this could lead to

If it works, this could point toward a practical tool to help people with severe obesity gain muscle and lose fat before joint replacement surgery, potentially improving surgical outcomes.

What could go wrong

This is a small, early-stage study with only 60 participants, so results may not apply broadly. The wristband may not provide enough benefit over standard coaching alone.
