NCT04241172

Brief Summary

This study is a multicenter non-randomized single-blind controlled trial, aimed at investigating the feasibility and efficacy of hydrotherapy based on IVR, for the patients with TKR(Total Knee Replacement), on the function, gait performance, postural balance control, and knee edema reduction. The protocol was draft according to the Consolidated Standards of Reporting Trials (CONSORT ) checklists. A total of 96patients with total knee prosthesis will be recruited and divided into three groups, to receive a traditional rehabilitation (TR) program, traditional hydrotherapy (TH)or hydrotherapy through immersive virtual reality (HIVR) using Bts-Nirvana. Assessments will be performed at baseline and at the end of treatment.

Outcome Measures

Primary Outcomes (1)

  • Changes in Time Up & Go Test

    Time Up and Go test (TUG): TUG is a test used to determine fall risk and measure the progress of balance, sit to stand and walking. The patient starts in a seated position, then stands up, walks 3 meters, turns around, walks back to the chair and sits down. If a patient took 14 seconds or longer to perform the test he was classified as high-risk for falling

    At baseline (day 1-T1) and at the end (day 21 -T2) of the treatment.

Secondary Outcomes (1)

  • Change in 10-Metre Walking Test (10MWT)

    At baseline (day 1-T1) and at the end (day 21 -T2) of the treatment.

Study Arms (3)

Immersive Virtual Reality (HIVR)

EXPERIMENTAL

The HIVR exercises will be performed using Nirvana system, a medical device based on virtual reality specifically designed to support motor rehabilitation, by projecting aquatic scenarios on the floor that simulates the movement and the noise of the water due to the motor exercise execution by the patient. In particular, the following virtual reality scenarios will be used: * "Swimming pool": the environment represents a swimming pool (water and edge). The patient must perform exercises by moving the lower limbs while sitting on a chair. The virtual environment gives the sensation of having the lower limbs immersed in water above the knees; * "Water metal": the environment gives the feeling of being immersed in water up to the waist. The subject interacts with the virtual water performing walking exercises and receiving visual and auditory biofeedback.

Device: Experimental: Immersive Virtual Reality (HIVR)

Traditional Hydrotherapy (TH)

ACTIVE COMPARATOR

The TH group exercises will be performed in a swimming pool suitable for hydrotherapy treatments. In particular, patients will perform: * exercises with patients sitting on the swimming pool edge with lower limb immersed in the water; * flexion-extension of the knee; * leg and hip circling; * flexion-extension of the ankle; * triple flexion; * water walking exercises.

Procedure: Traditional Hydrotherapy (TH)

Traditional Rehabilitation (TR)

ACTIVE COMPARATOR

The TR group exercises will be performed in the gym with a physiotherapist. In particular, patients will perform: * exercises with a patient sitting on a chair (3 minutes per exercise): * flexion-extension of the knee; * leg and hip circling; * flexion-extension of the ankle; * triple flexion; * walking (with and without aids).
