About

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.

Full description

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.
