Insole-based Visual Biofeedback for Weight-bearing in Total Hip Replacement

University of Pavia40 enrolled

Overview

The study investigates the effects of visual biofeedback, based on a sensorized system for the dynamic evaluation of the plantar pressure versus rehabilitation with traditional verbal instructions of the physiotherapist, on weight bearing distribution in patients who underwent first total hip replacement. The study is a randomized controlled trial, with parallel groups, without blinding.

Forty patients, who underwent first total hip replacement surgery were enrolled and divided into two groups on second postoperative day. Experimental group followed the training wearing sensorized insoles that provided plantar pressures and shift of foot center of pressure images on three monitors. Control Group followed verbal instructions of physiotherapist during training. From 4th to 10th postoperative day both groups followed the same rehabilitation program including exercises to restore correct weight bearing.

Interventions

Visual biofeedback with the use of sensorized insolesDEVICE

Between the 4th and the 10th day post surgery, both groups performed the same rehabilitation protocol. The experimental group was re-educated to the correct gait dynamics by wearing the sensorized insoles and by using a specific software's graphical interface as a visual biofeedback.

Standard rehabilitation based on physiotherapist's verbal instructionsOTHER

Between the 4th and the 10th day post surgery, both groups performed the same rehabilitation protocol.The Control group did not wear the insoles, but it carried out the rehabilitation programme under the physiotherapist supervision and with his verbal feedbacks.
