Open chain exercises (OKE) are exercises that are performed where the hand or foot is free to move. The opposite of OKE are closed kinetic chain exercises (CKE). Both are effective for strengthening and rehabilitation objectives. [ 1 ]

An example is the simple open chain formed by links connected in series, like the usual chain, which is the kinematic model for a typical robot manipulator. [ 2 ] Mathematical models of the connections, or joints, between two links are termed kinematic pairs .
Closed chain exercises are often compound movements, that generally incur compressive forces, while open-chain exercises are often isolation movements that promote more shearing forces. [ 1 ] CKC exercises involve more than one muscle group and joint simultaneously rather than concentrating solely on one, as many OKC exercises do (single-joint ...

An example of a simple open chain is a serial robot manipulator. These robotic systems are constructed from a series of links connected by six one degree-of-freedom revolute or prismatic joints, so the system has six degrees of freedom. An example of a simple closed chain is the RSSR (revolute-spherical-spherical-revolute) spatial four-bar linkage.

In classical mechanics, a kinematic pair is a connection between two physical objects that imposes constraints on their relative movement ().German engineer Franz Reuleaux introduced the kinematic pair as a new approach to the study of machines [1] that provided an advance over the notion of elements consisting of simple machines.
