Open vs Closed Kinetic Chain Exercises

1
Open vs Closed Kinetic Chain Exercises
2
Open vs Closed

• Closed Kinetic chain exercise
• When the distal segment of the lower extremity is
  fixed ( as in when foot is weight bearing) the
  kinetic chain is said to be closed

3
Open vs closed

• Open Kinetic Chain exercise
• The distal segment is mobile ( not fixed)

4
Open vs Closed

• Despite the recent popularity in rehab to use
  closed kinetic chain exercises , both open and
  closed exercises do have there place in a rehab
  program

5
Characteristics

• Closed kinetic chain exercises
• Increased joint congruency thus stability
• Decreased joint shear
• Decreased acceleration forces
• Large resistance forces
• Stimulation of proprioceptors
• Enhanced dynamic stability

6
Characteristics

• Open kinetic chain exercises
• Increased acceleration forces
• Decreased resistance forces
• Increased distraction and rotational forces
• Increase deformation of joint and muscle
  mechanoreceptors

7
Closed vs Open

• From a biomechanical perspective it has been
  suggested that closed kinetic chain exercises are
  safer and produce forces and stresses that are
  potentially less of a threat to healing
  structures
• Closed kinetic chain exercises tend to be more
  functional

CKC Lower Extremities

• In sport medicine setting several different CKC
  exercises have gained popularity
• Mini squats, wall slides, leg press lateral
  step ups, step ups, lunges, slide board ,
  terminal knee extension using tubing, BAPS board
  , mini-tramp

9
CKC Upper Extremities

• CKC exercises are used mostly in lower extremity
  rehab , however they can be incorporated into
  upper extremity rehab
• Examples include push ups (bench press), chin
  ups, hand stands
