There are 3 components which make usage
of closed kinetic chain exercise advantageous in early
rehabilitation. Firstly, the exercise environment can be
controlled. This allows the focus to be taken away from
the arm as an integrated unit with high dynamic demands
and place it in a stable, axially loaded, and static setting.
Secondly, closed chain exercises are ideal for working “at”
specific ranges of motion compared to working “through”
a range of motion which helps to provide a “snapshot”
within the full arc of normal motion. Finally, closed chain
exercises allow the rotator cuff and scapular musculature to
be unloaded by decreasing the amount of force generated
and stress applied to the involved soft tissues. These type
of exercises are best suited for re-establishing the proximal
stability and control in the links of the kinetic chain such as
the pelvis and trunk.
