NCT03047252

Brief Summary

The study was designed to test patient acceptance and system usability and to assess clinical outcomes of a home-based rehabilitation program using a novel kinematic biofeedback system in the rehabilitation after total knee replacement versus conventional rehabilitation, This system allows the patients to perform independent rehabilitation sessions at home, under remote monitoring from the clinical team. The investigators hypothesize that the system will be well received by patients and that the clinical outcomes will be at least similar those of conventional rehabilitation. This is a quasi-randomized controlled trial with active comparator. Patients will be enrolled pre-operatively and divided into 2 groups: experimental group and conventional rehabilitation group according to geographical criteria. Both groups will perform 8 weeks of rehabilitation starting between day 7 and 10 after surgery. The experimental group will perform daily rehabilitation sessions at home using the system, under remote monitoring from a physical therapist. The conventional rehabilitation group will perform 1h rehabilitation sessions 3 times a week, at home, given by a physical therapist. The following feasibility outcomes will be registered: enrollment rate, retention rate (drop-outs), compliance to the program, independence of use, need for therapist contact and patient satisfaction. Clinical outcomes will be measured at weeks 4 and 8 and then at 3 and 6 months. The primary outcome will be measured in terms of patient performance in the Timed-up-and-Go (TUG) test in comparison with the pre-operative score. Secondary outcomes will be measured in terms of: b) Knee Osteoarthritis Outcome Score); c) range of motion of the knee joint.

Outcome Measures

Primary Outcomes (1)

  • 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 and 8 weeks after initiation of rehabilitation program and then at 3 and 6 months after surgery

Secondary Outcomes (2)

  • Change in Knee injury and Osteoarthritis Outcome Score (KOOS)

    Baseline; 4 and 8 weeks after initiation of rehabilitation program and then at 3 and 6 months after surgery

  • Change in Knee Range of Motion (degrees)

    Baseline; 4 and 8 weeks after initiation of rehabilitation program and then at 3 and 6 months after surgery

Other Outcomes (5)

  • Enrollment rate

    At the end of patient enrollment- up to 18 months after trial initiation

  • Retention rate

    At week 8

  • Independence of use

    For each patient, at week 8 or upon dropout.

  • +2 more other outcomes

Study Arms (2)

Experimental group

EXPERIMENTAL

Home-based rehabilitation sessions performed with the novel digital 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: Home-based rehabilitation with a digital biofeedback system

Conventional rehabilitation group

ACTIVE COMPARATOR

Home-based rehabilitation sessions provided by a Physical Therapist, 3 times a week for 8 weeks. Each session will have a duration of 60 minutes. Patients will be instructed to perform additional unsupervised sessions in at least two other days, but compliance to these extra sessions is not mandatory per protocol.

Other: Conventional Home-based rehabilitation

Interventions

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, based on the following principles: STAGE 1 (Weeks 0-2) Open kinetic chain exercises without added resistance: lying, sitting and standing (with support) Strengthening of hip flexors and extensors Ice pack application after each session and throughout the day as needed STAGE 2 (weeks 3-6) Open kinetic chain exercises with added resistance, progressing to closed kinetic chain exercises, with strengthening of knee flexors and extensors and knee stabilization Progression to standing exercises without support lying, sitting and standing (with support) Exercises with steps Ice pack application after each session and throughout the day as needed STAGE 3 (Weeks 7-8) Eccentric strengthening exercises Exercises involving steps Multi-directional exercises

Also known as: SWORD Phoenix
Experimental group

Patients will perform 3 weekly rehabilitation sessions, with a duration of 1 hour, for 8 weeks, provided by a physical therapist. The rehabilitation program will respect the following principles: STAGE 1 (Weeks 0-2) Soft tissue massage Active assisted mobilisation of the knee to increase range of motion Gait training with bilateral support Open kinetic chain exercises without added resistance Strengthening of hip flexors and extensors Ice pack application STAGE 2 (weeks 3-6) Soft tissue massage Active assisted mobilisation of the knee to increase range of motion Open kinetic chain exercises with added resistance, progressing to closed kinetic chain exercises, with strengthening of knee flexors/ extensors and knee stabilisation Gait training with progressive withdrawal of external support Ice pack application STAGE 3 (Weeks 7-8) Eccentric strengthening exercises Exercises involving steps Weight-bearing exercises on uneven surfaces Ice pack application

Conventional rehabilitation group
