Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Despite best efforts to provide standardized and effective rehabilitation sessions post-total knee replacement (TKR), there are a few factors that may result in sub-optimal recovery in this group of patients. There is a need to develop innovative rehabilitation strategies that (i) provide patients with accurate cues allowing for better compliance and exercise performance, (ii) allow for therapists to ensure continuity of care, monitor compliance, and identify deviation from recovery trajectories post-discharge, prior to their first outpatient appointment, and (iii) reduce reliance on manpower and variability during rehabilitation sessions.

Technological solutions that empower patients and allow home-based rehabilitation to take place without the need for real-time human supervision could be the key to improving effectiveness and lowering costs. A mobile application which detects key landmarks on the body for human pose estimation will allow patients to perform their rehabilitation exercises with real-time feedback allowing for proper execution of the exercises. Physiotherapists will be able to access the data generated from the exercise session via a command centre to monitor patients' recovery progress and compliance.

The primary aim of this pilot study is to evaluate the feasibility of using a mobile application during rehabilitation in patients after a TKR surgery. The secondary aim is to study the effects of using a mobile application during rehabilitation on knee functional status, exercise self-efficacy, and treatment satisfaction after TKR surgery.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard rehabilitation program

Group Type ACTIVE_COMPARATOR

Standard rehabilitation program

Intervention Type OTHER

All participants will be seen by physiotherapists in the ward post-TKR surgery and undergo standard inpatient rehabilitation. Patients will be given instructions to perform assigned exercises 3 times daily. Physiotherapists will perform the required assessment/review, education, and intervention.

Mobile application

Group Type EXPERIMENTAL

Mobile application

Intervention Type DEVICE

Participants will be instructed on the installation and use of the mobile application on their personal mobile phones. Participants will then have to perform the assigned exercises using the mobile application 3 times daily. Physiotherapists will still perform the required assessment/review, education, and intervention.

Interventions
