closed kinetic chain

closed ki·net·ic chain

(klōzd ki-netik chān)
Physical activity in which the terminal end of a body segment is involved in functional forces; motion in one joint results in obligatory coupled motions at others.

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.

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.
