The Effectiveness of Rehabilitation in Gait Recovery After Knee or Hip Arthroplasty

Study Overview
=================
Brief Summary
-----------------
This study aims to evaluate the effectiveness of rehabilitation on gait recovery in subjects after knee or hip arthroplasty. Assessment is performed the day after admission (T0) and the day of discharge (T1), in a post-acute rehabilitation hospital, through an optoelectronic system (BTS DX-400). Other functional scales are administered to the subjects. during the rehabilitation period, subjects received conventional physiotherapy.
