Open kinetic chain exercises (OKC) or open chain exercises are exercises that are performed where the hand or foot is free to move. The opposite of OKC are closed kinetic chain exercises (CKC). Both are effective for strengthening and rehabilitation objectives.
An isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term isometric combines the Greek words Isos (equal) and metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied.
