Description

<p>The purpose of this study was to objectively measure physical activity (PA),by intensity, in patients who underwent high tibial osteotomy (HTO) during hospitalization and after discharge, and to investigate how it changes after discharge. The subjects included 17 patients (mean age 66.8 years, 88.2% female) who underwent HTO for knee osteoarthritis and who were discharged according to the protocol. PA was measured using a triaxial accelerometer 5 weeks post-operatively (during hospitalization) and 8 weeks postdischarge (post-discharge), and data were classified into four categories: “sedentary”, “low”,“medium”, and “high intensity.”The percentage was then divided by daily time, and total wearing time was calculated and compared. The results of the study showed that the median spend times after being discharged was 546 min for sedentary behavior, 397 min for low-intensity PA, 36 min for medium-intensity PA, with no high-intensity PA observed. The percentage during hospitalization and after discharge showed that medium-intensity PA increased significantly after discharge, but the sedentary behavior and low-intensity PA did not. These results suggest that patients who underwent HTO remained seated for a large amount of time after discharge, with no change in sedentary behavior.</p>
