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).

Arm Intervention/treatment
Experimental: Experimental group
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
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.

Primary Outcome Measures :
  1. Change in the Timed up and Go Test score [ Time Frame: Baseline, 4 weeks into the rehabilitation program and at the end of the program (week 8) ]
    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.

Secondary Outcome Measures :
  1. Change in the Hip Osteoarthritis Outcome Score/Knee Osteoarthritis Outcome Score [ Time Frame: Baseline, 4 weeks into the rehabilitation program and at the end of the program (week 8) ]
    The HOOS/KOOS are standardized and validated patient outcome scores that assess functional limitation in patient with hip/knee osteoarthritis

  2. Change in Hip/Knee Range of Motion [ Time Frame: Baseline, 4 weeks into the rehabilitation program and at the end of the program (week 8) ]
    This will be measured (in degrees) automatically by the device
