Wearable Sensors for Monitoring Recovery After Total Knee Arthroplasty

Investigating the Potential of Wearable Sensors for Monitoring the Postoperative Recovery of Total Knee Arthroplasty Patients: A Protocol for Prospective Longitudinal Observational Study

Sponsor

Aalborg University Hospital

Enrollment

30 participants

Start Date

Mar 12, 2024

Study Type

OBSERVATIONAL

Conditions

Arthroplasty Replacement, Knee

Summary

The goal of this observational study is to investigate the potential of wearable sensors for monitoring the postoperative recovery of patients after TKA. The main question the study aims to answer is: • whether alterations in gait characteristics and the changes in PA levels measured by wearable PA trackers can accurately reflect a patient's postoperative recovery status and provide clinically relevant information to aid their management. Participants will wear PA trackers during the perioperative period of TKA (2 weeks before until 3 months after, and then agin for 2 weeks one year after the surgery) and we will analyze their gait and PA and correlate them with their recovery after surgery.

Interventions

OTHERMeasuring gait

Measurements are performed by PA trackers. The measurements include: * Lower limb 3D linear accelerations according to gait bouts collected and stored as time-series of linear accelerations with a frequency of 12.5 Hz. * Details on the amount of time spent lying down, sitting, and standing, as well as the number of steps and sit-to-stands completed throughout the day. This information will be stored in 15-minute epochs and then summarized into daily summaries for analysis.
