Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Harmonic ratio measured with accelerometer. Timepoint: Baseline (before intervention) and one week after intervention (one month intervention). Method of measurement: Based on studies to calculate the harmonic gait ratio, accelerometer (Biomethrics) will be fitted to the lower lumbar vertebrae(l4-l5) at the lower back. Gait analysis will be performed using an accelerometer in the laboratory environment as individuals walk a 15-meter-long, horizontal path at their usual speed; a heel switch will be connected in the heel area of right foot to define the start of the walking cycle ; the linear acceleration of the trunk will be sampled along the anterior-posterior, medial-lateral, and vertical axes at a frequency of 200 Hz. Signal processing will be performed using matlab software. To calculate the harmonic ratio using fourier transformation, the contents of the in phase accelerated signals (even harmonics) are compared to the contents of out-of-phase signals (odd harmonics). | — |
Secondary
| Measure | Time frame |
|---|---|
| Pain and disability measered with KOOS quationniare. Timepoint: Baseline (before intervention) and one week after intervention (one month intervention). Method of measurement: KOOS Questionnaire: Knee Injury and Osteoarthritis Outcome Score This questionnaire contains 42 items that assess the patient's opinion on the five dimensions related to the knee and its problems, including: pain (9 questions), other specialized symptoms of illness (7 Questions), daily life performance (17 questions), recreational and sports performance (5 questions), and knee-related quality of life (4 questions).;Balance. Timepoint: Baseline (before intervention) and one week after intervention (one month intervention). Method of measurement: Star Equilibrium Test: To do this test, 8 strip strips with a 45 degree angle are attached to the ground. Evaluation will be done with the bare foot, and the patient will be asked to stand in the center of the star with the leg that is stance positioned and center the arch, while maintaining the balance on the leg in the center, and with the other foot touch the longest distance on any tape.;Pain meassured with PI-NRS (Pain intensity numeric range scale). Timepoint: Baseline (before intervention) and one week after intervention (one month intervention). Method of measurement: An 11-point scale that reports the patient's pain level. The patient is asked to choose a number between 0 and 10 that is most proportional to their pain intensity.;Isometric strength of quadriceps. Timepoint: Baseline (before intervention) and one week after intervention (one month intervention). Method of measurement: Isometric quadriceps muscle strength will be measured using a handheld dynamometer. | — |
