Knee osteoarthritis (KOA) is a degenerative joint disease causing pain, stiffness, and reduced quality of life. While treatments often focus on drugs or surgery, noninvasive exercises like core stabilization and ankle/foot strengthening show potential but lack comparative studies. Understanding anatomical factors like Achilles tendon (AT) thickness is crucial for targeted rehabilitation, though measurement reliability remains an issue. This study aims to compare the effects of these exercises on KOA symptoms and evaluate the use of digital calipers for AT thickness measurement, aiming to enhance clinical management of KOA.
The objective of the study is: 1. To determine the interrater and intrarater reliability of digital calliper to measure the side to side Achilles tendon thickness. 2. To determine the impact of 24 sessions of core stability translated in gait ambulation. 3. determines the relationships between Achilles tendon thickness (ATT), knee symptoms/functions, and foot alignment in knee OA patients, considering their interconnected biomechanical nature. 4. compare the effects of core stability and ankle-foot strengthening exercises on clinical outcomes in KOA patients

Visual Analogue Scale (VAS) at rest
Changes from baseline, Visual Analogue Scale (VAS) is the most commonly used scale in which the pain rate ranges from 0 (no pain) to 10 (worst pain). The level of knee perception of pain is assessed by using the VAS.
Time frame: 8 weeks
Knee Injury and Osteoarthritis Outcome Score (KOOS)
The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a 42-item, patient self-administered patient outcome measure designed to measure knee health in five subscales (Pain, Symptoms, Activities of Daily Living (ADL), Sport and Recreation and knee-related Quality of Life).
Time frame: 8 weeks
40-m fast-paced walk test
This test was conducted as per the guideline of OARSI. The 40-meter Fast-Paced Walk Test (40m FPWT) is a brief physical performance test primarily used to measure maximum short-distance walking speed and the ability to change directions.
Time frame: 8 weeks
30 seconds chair stand test
The 30-Second Chair Stand Test (or 30CST) is a quick physical test used to measure lower-body strength and endurance in adults, especially older individuals.
Time frame: 8 weeks
stair climb test
Step Stair Climb Test (SCT) is a physical performance test used to evaluate functional strength, balance, and agility in individuals with mobility limitations.
Time frame: 8 weeks
Navicular/foot ratio
It is calculated as the quotient of the height of the navicular tuberosity divided by the total length of the foot.
Time frame: 8 weeks
Achilles tendon thickness (ATT)
measured side to side thickness using the digital calliper
Time frame: 8 weeks
