Characteristics of Early Postoperative Sedentary Time in Patients with Hip Fractures.

OBJECTIVES

This study aimed to investigate the sedentary time of patients with hip fractures, including those with cognitive decline, in the early postoperative period.

METHODS

Participants were patients with hip fractures treated at our hospital. A triaxial accelerometer was attached to the contralateral hip, and activity was recorded for three postoperative days (4320 min).

RESULTS

Thirty patients (mean age: 86.5 years; female, n=23) were included in the analysis. The mean activity times were: sedentary time, 1364.0 ± 59.9 min/day (mean ± standard deviation); light-intensity physical activity time, 71.9 ± 57.8 min/day; and moderate-to-vigorous-intensity physical activity time, 4.1 ± 3.2 min/day. Sedentary time was linked to the scores on the Mini-Mental State Examination-Japan.

CONCLUSIONS

: Early postoperative patients with hip fractures have long sedentary times and less time for moderate-to-vigorous-intensity physical activity. Patients with hip fractures with cognitive decline have significantly longer sedentary time than those without cognitive decline.
