Evaluation of Safety and Efficacy of ReHub in Patients Who Underwent Primary Total Knee Arthroplasty

Bio-Sensing Solutions S.L. (DyCare)52 enrolled

Overview

This is a randomized, non-blinded, parallel assignment, clinical trial for the evaluation of safety and efficacy of ReHub, a telerehabilitation system made up of a cloud platform and an exercise kit with smart sensors, for performing rehabilitation exercises after a primary Total Knee Arthroplasty. Primary TKA patients are allocated randomly to the control arm or the experimental arm with a 1:1 ratio. Both arms follow the usual rapid recovery protocol for TKA surgeries at Hospital Clínic de Barcelona, which includes discharge after 2-3 days from the surgery, the prescription of a daily plan of 5 exercises for autonomous rehabilitation and domiciliary visits by a physiotherapist starting approximately 2 weeks after the surgery. The experimental arm participants use ReHub to do their exercises instead of working independently and physiotherapists monitor their performance and adherence remotely. Outcomes assessment is performed at hospital discharge (baseline), at stitch removal (2 weeks after baseline) and 2 weeks after stitch removal (4 weeks after baseline).

Interventions

Usual intervention at Hospital Clínic de Barcelona for post-operative rehabilitation of TKA patients. Participants, already at home after hospital discharge, must perform 5 different exercises 4 times a day (twice in the morning, twice in the afternoon). Participants are also encouraged to walk and stretch their legs. Domiciliary visits by a physiotherapist start at approximately 2 weeks after the surgery to help participants do the exercises.

ReHubDEVICE

Participants use a telerehabilitation platform, ReHub, as a guide to perform the TKA rehabilitation exercises of the Rapid Recovery Rehabilitation Programme intervention. The exercise plan in ReHub is carried out by a site physiotherapist on the first day after discharge by using ReHub to acquire the participant's movement pattern with a wearable inertial sensor that transmits data to the platform. The wearable inertial sensor participants must wear tracks movement while they do the TKA rehabilitation exercises. Movement is analysed and feedback is given in real time. At the end of each exercise, participants can select if they have felt pain in a scale from 1 to 10. A physiotherapist monitors the participants' progress remotely.

Outcomes

Primary Outcomes

Change in Active Knee Range of Motion (º)

Range of motion of the replaced knee without the aid of the outcomes assessor will be measured with a conventional goniometer.
