Overview

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.

Detailed description

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

Interventions

  • Other core stability exercise
    1. Isometric quadriceps exercises involving knee extension 2. Maximum isometric exercise for the quadriceps
  • Other foot-ankle strengthening exercise
