Abstract

© 2019 Professor P K Surendran Memorial Education Foundation This study evaluates physical activity in patients with advanced hip OA using Fitbit and whether a correlation exists between the number of steps taken per day (SPD) and the reported outcome. Methods: 122 patients were prospective enrolled. Patient-reported outcomes were collected. Patients were asked to wear a Fitbit for 24 h a day on seven consecutive days. Result: The mean number of SPD was 5721 ± 3920. The UCLA, HHS and SF-12 PCS demonstrated a statistically significant positive correlation with the SPD. Conclusion: Wearable technology is reliable in objectively measuring the level of physical activity in hip OA and correlates with reported outcomes.
