Correlation between hip osteoarthritis and the level of physical activity as measured by wearable technology and patient-reported questionnaires

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. 122 patients were prospective enrolled. Patient-reported outcomes were collected. Patients were asked to wea...

Description
Summary: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. 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. The mean number of SPD was 5721 ± 3920. The UCLA, HHS and SF-12 PCS demonstrated a statistically significant positive correlation with the SPD. Wearable technology is reliable in objectively measuring the level of physical activity in hip OA and correlates with reported outcomes.
