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.

Rehabilitation protocol based on muscle strengthening with isometric, isotonic and counter-resistance with progressive load exercises. Intervention consisted of warm-up phase with passive, active-assisted and active movements, and a work-out phase
Balance and proprioception training using parallel bars, unstable plates, ramps and stairs
Stability tests, weight changes and stability limits, performing both anterior-posterior and medial-lateral movements simultaneously in some cases
Berg Balance Scale
Balance among older people with impairment in balance function by assessing the performance of functional tasks from the total score achieved in the 14 items test
Time frame: Change from baseline (two weeks after intervention) to after four weeks of training
Functional Reach (cm)
Assesses a patient's stability by measuring the maximum distance an individual can reach forward while standing in a fixed position
Time frame: Change from baseline (two weeks after intervention) to after four weeks of training
Timed Up and Go Test (s)
Dynamic balance assessment. Also points at the risk of falling. Time of getting up from a chair, walk three meters, come back and sit again, measured in seconds
Time frame: Change from baseline (two weeks after intervention) to after four weeks of training
Romberg Tests
Total score achieved with open and closed eyes and on firm surface
Time frame: Change from baseline (two weeks after intervention) to after four weeks of training
Knee Range of Mobility (º)
Knee Range of Mobility (Flexion, Extension) in degrees
Time frame: Change from baseline (two weeks after intervention) to after four weeks of training
Kendall and Lovet scale
Muscle Balance estimated with with Kendall and Lovet scale (score from 0 to 5)
Time frame: Change from baseline (two weeks after intervention) to after four weeks of training
