Telerehabilitation of Patients After Knee Surgery

Study Overview
=================
Brief Summary
-----------------
This project is aimed to investigate the feasibility of employing communication and sensor technologies for the patient after a knee operation. In the study, it is hypothesized that the effectiveness of postoperative rehabilitation programs might be improved by establishing electronic communication between healthcare professionals and the patients. It is also believed that users satisfaction and patients quality of life will be improved. The telerehabilitation program promises a synchronized communication as well as an individualized training program (by health professionals) based on the patient's electronic reports.

Detailed Description
-----------------
Aim The objectives of this project are to assess the feasibility of using a telerehabilitation program for patients after a knee operation and investigate the acceptance of the provided solution by the patients and healthcare professionals. Hypothesis It is hypothesized that the acceptance and satisfaction of patients and healthcare professionals by using the telerehabilitation program will be high and correlated with patients' exercise adherence and health recovery. Telerehabilitation Group (Target Group) The subjects will be recruited before the operation and will be followed during an 8-week rehabilitation period. In addition to the telerehabilitation program, the subjects will receive the regular treatment offered by Farsø Hospital in connection with total knee replacement surgery and are to follow the same rehabilitation procedure as regular patients (see below). Before the operation, the project physiotherapist will hand over the telerehabilitation system equipment and instruct the subject how to use the system. In addition, the physiotherapist will also ask the subject to follow the instruction process and try the available services a few times. The physiotherapist makes sure that the subject can operate the system easily and without any challenges.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Usability of the telerehabilitation program: semi-structured interview | The data is collected by a semi-structured interview | The interview is conducted two weeks after discharge. | 
| Exercise adherence | Measured by telerehabilitation system reports | Everyday, started after discharge and for period of 8-weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Self-reported pain, stiffness, and physical function: KOOS | Measured using Knee injury and Osteoarthritis Outcome Score (KOOS) | After discharge (weeks 2, 8) | 
| Self-reported pain and physical function: OKS | measured by an electronic version of Oxford Knee Score (OKS) | Baseline (before operation), and after discharge (weeks 0,2,4,6,8) | 
| Self-reported pain: VAS | Measured by an electronic report of the visual analog scale (VAS) of pain [minimum 0, Maximum 10] higher values represent a higher level of pain | Baseline (before operation), and every third day after discharge (for period of 8 weeks) | 
| Self-reported knee swelling | measured by an electronic report of knee circumference | Baseline (before operation), and every third day after discharge (for period of 8 weeks) | 
| Quality of life: EQ-5D | Measured using Euro Quality of Life - 5 Dimension (EQ-5D) | After discharge (weeks 2, 8) | 
| Users satisfaction: semi-structured interview | Measured by semi-structured interview | The interview is conducted two weeks after discharge. |
