Lower-Extremity Kinetic Chain Exercise Program for Achilles Tendinopathy

Achilles tendinopathy is a common condition that causes pain, stiffness, and reduced function of the Achilles tendon. It can affect both physically active individuals and the general adult population, often making everyday activities and exercise more difficult. Exercise therapy is widely used as the primary conservative treatment; however, rehabilitation programs that focus only on the Achilles tendon may not address movement impairments involving the entire lower extremity. This randomized controlled trial will evaluate a rehabilitation program based on the lower-extremity kinetic chain in adults with chronic mid-portion Achilles tendinopathy. Fifty participants will be randomly assigned to receive either a kinetic chain-based exercise program or a conventional rehabilitation program. Assessments will be completed before the intervention begins and again after it is finished. The study will measure postural stability using the Biodex Balance System, foot and ankle function using the Foot and Ankle Outcome Score (FAOS), pain intensity using the Visual Analog Scale (VAS), and ankle range of motion using a goniometer. The results will provide information on the effects of a rehabilitation approach that addresses the coordinated function of the lower extremity in people with chronic Achilles tendinopathy.
