Knee Osteoarthritis, Physical Performance Parameters, Quality of Life (QOL), Ultrasound
Conditions
Brief summary
The investigators perform a prospective controlled study and assess gait parameters in bilateral knee osteoarthritis (KOA) elderly patients with wireless system - BTS G-WALK, pre- and post-rehabilitation program. The complete assessment include: ultrasound exam, gait parameters and functional scale. The investigators investigate the real impact of complete rehabilitation program, with gait control, on the physical performance and functional status.
Interventions
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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Physical performance - gait analysis | 3 months | Timed Up-and-Go (TUG) test (seconds) - participants stood up from an armed chair, walked at a safe and comfortable pace to a line 3 m away, crossed the line, turned, and returned to a sitting position in the chair; none of the patients used a walking aid and the time to complete the task was recorded. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Functional status - quality of life | 3 months | WOMAC scale contains 24 specific questions divided into three domains: pain (P-WOMAC; 5 items), stiffness (S-WOMAC; 2 items) and physical function (PF-WOMAC; 17 items). The score of each question ranges from 0 to 4. The 0 score is equivalent to maximal functional status and high scores 96 indicates a minimum status, with high disruption in day to day tasks. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Quadriceps muscle index | 3 months | In ultrasound exam, after establishing the midway point between the tip of the greater trochanter and the lateral joint line of the knee, the investigators identify the muscle tissue; the thickness of the quadriceps muscle (in centimeters) is established by measuring the space between the cortex of the femur and therefore the most superficial muscular fascia. Quadriceps muscle index is calculated as sum of both quadriceps muscle thickness Right and Left centimeters/ participant square height (square meters). Participant is exam with the knee extended. |
| Physical performance - gait analysis. Symmetry index | 3 months | Symmetry index - for the participant's ability to have an identical model of acceleration and deceleration of their center of mass regardless of the side of the gait cycle |
