WebNov 2, 2024 · The close chain kinematics of the hip is characterized by the movement of the pelvis (acetabulum) over the head of femur. If the femur is fixed as seen with weight bearing, the hip joint motion is facilitated by the movement of proximal segment (pelvis) and thus we consider this as the close chain kinematics. WebClosed kinetic chain exercises or closed chain exercises (CKC) are physical exercises performed where the hand (for arm movement) or foot (for leg movement) is fixed in space and cannot move. The extremity remains in constant contact with the immobile surface, usually the ground or the base of a machine.

WebApr 14, 2024 · According to the simplified model of each joint, the kinematic chain of the human lower limb is shown in Figure 1b. The movements during walking mainly occur in the sagittal plane, so we simplified the lower extremity kinematic model as a planar kinematic model (Figure 1c). As a result, we streamlined the hip joint and ankle joint as one DOF ... Web1.2.1 Simple Kinematic Chains A kinematic chain is simple if each link in the chain is coupled to at most two other links. The degree of connectivity (DOC) of a link indicates the number of rigid bodies joined to it. If all links are binary (DOC= 2) the simple chain is closed. E.g. a four-bar mechanism. Alternately the simple chain is open with ...
