Given the importance of making the athlete powerful in motor control, closed and open kinetic chain
exercises are commonly applied by coaches and trainers.
Biomechanically closed, partially progressive kinetic chain exercises are safer and more functional than open kinetic chain

exercises." Medicine & Science in Sport and Exercise, 4 (1998): 556-69.
Open kinetic chain
(OKC) exercises are lower limb activities performed where the distal segment of the limb is free to move.
The use of therapeutic exercise in the reconstruction of anterior cruciate ligament using open kinetic chain
and closed kinetic chain
The entire lower extremity composes an open kinetic chain
The first set of desk exercises or "Scissors" challenges the pelvic area in "an open kinetic chain
setting" which progresses into a functional position.
However, these studies have addressed a lower limb moving in an open kinetic chain
, typically involving the kicking leg.
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
When the foot is not weight bearing but moving freely in the air, movement is in open kinetic chain
. (11) The ankle joint is not supporting it; rather, stability is dependent on passive and active supporting mechanics (ligaments and muscles).
(13,14) However, if a medial meniscus injury has occurred without any damage to the ACL, introduction of open kinetic chain
exercises takes precedence.
Analysis of the data suggests that open kinetic chain
exercise (isokinetic training) did not lead to functional improvements on a closed kinetic chain activity (Rapid Step Test).
