Twenty-Four Seven Functional Status in Total Hip Replacement

This study is looking at how people move and do everyday activities after having a **total hip replacement**. A total hip replacement is a surgery where a doctor replaces a worn-out hip joint with a new one. The study uses a special iPhone and two wrist monitors to track movements and activities. About 25 people will join this study. It starts with a 1-week Screening and Baseline period, followed by up to 6 weeks of checking after surgery. Most of the study is done remotely, using data collected from the devices.

• **Time Commitment**: The study lasts up to 8 weeks, with the main period being 6 weeks after surgery.
• **Participation**: Mostly remote, but includes a couple of clinic visits at the start and end.
• **Data Collected**: Physical activity, heart rate, sleep quality, and health reports.

To join, you must be 30 or older, plan to have a hip replacement due to arthritis, and be able to use a smartphone. You cannot join if you have certain health conditions or other hip surgeries.
