Considerations in lower extremity closed kinetic chain exercise: A clinical perspective

Because of the widespread use of CKC exercise in the rehabilitation of lower extremity injuries, athletic trainers and therapists need to better understand the mechanics and objectives of applying such exercises. There are many different types of CKC exercises, but they do not all have the same effects on the lower extremity kinetic chain, particularly at the knee. Although these exercises are commonly advocated in reestablishing joint range of motion and muscle strength, they can be valuable in reacquiring proprioceptive feedback and kinesthesia, as well. It is important for the athletic trainer or therapist to keep in mind the athlete's needs when developing and implementing an exercise program.
