Brief Summary

Knee osteoarthritis produces degeneration and joint wear that greatly affects the patient's proprioceptive system increasing instability. After total knee arthroplasty intervention, it is recommended that the patient performs a rehabilitation procedure to minimize deficits caused by surgery. In this job it is essential to insist on the importance of recovering balance after total knee arthroplasty intervention, and assess a specifically designed protocol to restore its function. An intervention which includes a dynamometric platform as a training method was proposed. The randomized clinical trial compared a control group that performed balance exercises on parallel bars, unstable plates, ramps and stairs against an experimental group that included dynamometric platforms training as a differentiator.

Secondary Outcome Measures

Name	Time	Method
Romberg Tests	Change from baseline (two weeks after intervention) to after four weeks of training	Total score achieved with open and closed eyes and on firm surface
