Knee Osteoarthritis in Elderly People - Gait Analysis

"Ultrasound exam (initial and after 3 months) - with SonoScape S9Pro; the investigators exam the thickness of the quadriceps muscle group between the superficial fat-muscle interface and the cortex of the femur and calculate the quadriceps muscle index as sum of both muscle thickness RT and LT cm/height2 (m2). The exam is conducted by a qualified sonographer. The examination is carried out on a one-on-one basis in a private setting where only the participant and the sonographer are present.~Gait analysis with wireless system - BTS G-WALK; the investigators consider four gait parameters: Timed Up-and-Go (TUG) test, Symmetry index, Six Minutes Walking Test (6 MWT), and Walk cadence or average cadence (steps/min)."

The gait training is the distinguish aspect in rehabilitation program. Usually, KOA training include only kinetic measures, without gait control training

This type of special kinetic training includes Frenkel exercises for lower limb muscles and virtual / mirror exercises for different types of gait
