Efficacy of a Digital Biofeedback System for Home-based Rehabilitation After Total Joint Replacement

Study Overview
=================
Brief Summary
-----------------
The study was designed to assess the efficacy of a home-based rehabilitation program using a digital kinematic biofeedback system after total hip or knee replacement. This is a single-arm prospective study. Patients will be enrolled pre-operatively and will perform an 8-week rehabilitation program starting between day 7 and 10 after surgery. This program will consist of rehabilitation sessions performed independently by the patient at under remote monitoring from a physical therapist. Outcomes will be measured at baseline, 4 weeks into the rehabilitation program and at the end of the program. The primary outcome is the change in patient performance measure through the Timed-up-and-Go (TUG) test in comparison with the pre-operative score. Secondary outcomes will be measured in terms of: a) patient reported outcomes (Hip or Knee Osteoarthritis Outcome Score) and b) range of motion of the relevant joint (hip or knee).

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental group<br>Home-based rehabilitation sessions performed with the digital kinematic biofeedback system. Patients will be instructed to perform exercise sessions in at least 5 days per week, but compliance to this schedule is not mandatory per protocol. | Device: Digital kinematic biofeedback system<br>* The system will be used independently by the patients to perform rehabilitation sessions at home, under remote monitoring from the clinical team. A tailored rehabilitation program will be prescribed by the therapist and edited according to patient evolution.<br>* Other names: SWORD Phoenix;|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the Timed up and Go Test score | The timed up and go requires a patient to rise from a chair walk three meters around a piece of tape and return to the chair again as quickly as possible. | Baseline, 4 weeks into the rehabilitation program and at the end of the program (week 8) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the Hip Osteoarthritis Outcome Score/Knee Osteoarthritis Outcome Score | The HOOS/KOOS are standardized and validated patient outcome scores that assess functional limitation in patient with hip/knee osteoarthritis | Baseline, 4 weeks into the rehabilitation program and at the end of the program (week 8) | 
| Change in Hip/Knee Range of Motion | This will be measured (in degrees) automatically by the device | Baseline, 4 weeks into the rehabilitation program and at the end of the program (week 8) |
