The effectiveness of a proposed rehabilitation program using motor chain exercises Closed and open on the functional competence of the knee joint affected by partial torn meniscus in the Republic of Iraq

This current study aims to identify the efficiency of a proposed rehabilitation program, regarding the impact of Open Kinetic Chain (OKC) and Closed Kinetic Chain (CKC) exercises on the functional competence of a knee joint with a partial tear in the inner cartilage in the Republic of Iraq. In this regard, the researcher has used the 'Experimental Approach' by designing one experimental group for the pre- and post- measurements. In addition, the research sample was selected through the 'Purposive Method', consisted of eight (8) players from different sports activities, with a partial tear in the inner cartilage in the Republic of Iraq.
On this basis, the study has concluded that there are statistically significant differences between the pre-measurement and the post-measurement regarding the following variables: the overall balance of the body, the sensation of the pain's intensity, the motor range of the knee joint, and the muscular strength level of the muscles controlling the contraction and stretching of the knee joint; and that is in favor of the post-measurement. Furthermore, the proposed rehabilitation program has shown an effective impact on improving the level of overall balance, eliminating the pain permanently, and restoring the functional status of the knee joint to its previous state prior to the injury. Moreover, the proposed rehabilitation program has also shown great efficiency with regard to developing the flexibility of the knee joint, hence increasing the joint's motor range at the injured limb and reaching the normal motor range.
