Introduction[edit | edit source]
Closed kinetic chain exercise or closes chain exercise (CKC) is an exercise or movement where the distal aspect of the extremity is fixed to an object that is stationary.
With the distal part fixed, movement at any one joint in the kinetic chain requires motion as well at the other joints in the kinetic chain. Thus both proximal and distal parts receive resistance training at the same time[1].
Here are some characteristics of CKC and the differences with open kinetic chain exercises: [2]
| Characterisctic |
Closed kinetic chain exercices |
Open kinetic chain exercises |
| Stress pattern |
Linear |
Rotary |
| Number of joint axes |
Multiple |
One primary |
| Nature of joint segments |
Both segments move simultaneously |
One stationary, other mobile |
| Number of moving joints |
Multiple joint movements |
Isolated joint motion |
| Planes of movement |
Multiple (triplanar) |
One (single) |
| Muscular involvement |
Significant co-contraction |
Isolation of muscle group, minimal muscular co-contraction |
| Movement pattern |
Significant functionally oriented |
Often non-functional |
Biomechanical and neurophysiologic factors[edit | edit source]
Biomechanical:
CKC techniques emphasize the sequential movement and placement of functionally related joints and therefore require coordinated and sequential muscle activation patterns to control proper joint movement. [3]
Neurophysiologic:
Closed kinetic chain exercises stimulate the proprioceptive system by proprioceptive feedback to initiate and control muscle activation patterns. [3]
Exercises
[edit | edit source]
Closed chain upper-body kinetic exercises[edit | edit source]
Push-ups and derivatives, pull-ups or chin-ups, and dips. These concentrate on a co-contraction of the triceps brachii, biceps brachii, deltoids, pectoralis major and minor, and lower back for stabilization in various ratios depending upon angle and leverage.
Closed chain lower-body kinetic exercises[edit | edit source]
Squats, deadlifts, lunges, power cleans, and leg presses. These concentrate on a co-contraction of the quadriceps, hamstrings, hip flexors, soleus, and gastrocnemius muscles. The joints of movement include the knee, hip, and ankle.
Clinical Bottom Line[edit | edit source]
Many factors should be considered when deciding to use open kinetic chain exercises versus closed kinetic chain exercises. The patient's condition and stage of rehabilitation will aid in the clinician's judgement of exercise prescription.
