+A **closed chain** describes a kinematic system where the end of the chain is connected back to the beginning or to a fixed point, forming a complete loop. This arrangement constrains movement and distributes forces across multiple [Joints](/wiki/Joint), distinguishing it from an [Open Chain](/wiki/Open_Chain) system.
