Indeed, myoelectric activities of the VMO and VL were measured in the present study during functional closed kinetic chain
walking activity, while the aforementioned authors assessed their participants during resisted open kinetic chain knee extension.
In patients with anterior cruciate ligament (ACL) reconstruction, exercise for activities of the hamstrings and gastrocnemius are especially important in the closed kinetic chain
(CKC), and squat exercise is widely used in the rehabilitation program.
Many studies have suggested that closed kinetic chain
(CKC) exercises are an effective strategy to promote periscapular muscle activation, as well as for the maintenance of shoulder function (1,3,10,11,13,14,18,21).
Closed kinetic chain
(CKC) exercises refer to those activities where the distal part of the lower limb is fixed, while in open kinetic chain (OKC) condition, distal segment of the limb is free to move (13).
Congenital joint congestion with meniscus and saucy, prevents posterior displacement of the tibia, in the case of a posterior crossbreak, this kinematic fact also implies careful reinforcement exercises, quadriceps in the last degrees of extension (in predisposition) because as the flexural angle increases, the LCP stabilization voltage also increases Quadriceps can be trained in a closed kinetic chain
or open kinetic chain.

Upper Extremity Stability Test (Figure 3).
Peck recommends closed kinetic chain
exercises, such as leg squats and lunges, which are friendlier to arthritic knees.

and open kinetic chain exercises." Medicine & Science in Sport and Exercise, 4 (1998): 556-69.
The opposite of OKC is closed kinetic chain
Regarding the movement pattern, nine articles performed exercises in open kinetic chain and ten studies in closed kinetic chain
, of these, four performed squat, one squat associated with hip adduction, two used the step, one the leg press and one leg press associated with hip adduction.
Over the past 10 years, isokinetics has become the exercise modality of choice for rehabilitating the lower extremity; however, a review of literature indicates that closed kinetic chain
exercises have advantages over open kinetic chain exercises.
Three different axes of pronation and supination will be used as a base for describing related movements in closed kinetic chain
