Kinetic chain exercise
Kinetic chain exercise is a specific type of physical exercise that may be integrated into aerobics, circuit training, certain endurance training, weight lifting, pilates, yoga or kickboxing. It may also be used in physical therapy, such as knee rehabilitation.
A kinetic chain is a chain of joints exercised together. For example the hip, knee, and ankle joints, when taken together, comprise the lower extremity kinetic chain.
Whether used for rehabilitation purposes or for strengthening purposes, there are two types of kinetic chain exercises: open (OKC) and closed (CKC). Closed kinetic chain exercises (such as squatting) involve weight bearing while open kinetic chain exercises (such as active flexion-extension) of the leg do not.
In closed kinetic chain exercises, movement at one joint produces predictable movements at all other joints. Weight bearing closed kinetic chain activities may increase joint compressive force and thus enhance joint stability. In contrast, open kinetic chain exercises use isolated joint and muscle function and the motion is uni-planer.
Closed kinetic chain exercise has become popular in the last five to ten years for use after anterior cruciate ligament (ACL) reconstructive surgery. Closed kinetic chain exercises appear to have gained popularity over more traditionally used open kinetic chain exercises because many clinicians believe that CKC exercises are safer and more functional. Clinicians also contend that CKC exercise is equally effective as OKC exercise in restoring quadriceps femoris muscle force production following ACL reconstructive surgery.
