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 ...
The tibial tuberosity thus forms the terminal part of the large structure that acts as a lever to extend the knee-joint and prevents the knee from collapsing when the foot strikes the ground. [1] The two ligaments, the patella, and the tibial tuberosity are all superficial, easily palpable structures.
The opposite of OKC are closed kinetic chain exercises (CKC). Both are effective for strengthening and rehabilitation objectives. [1] Closed-chain exercises tend to offer more "functional" athletic benefits because of their ability to recruit more muscle groups and require additional skeletal stabilization. [2]
Complaints of locking sensation in the knee joint can be divided into true locking and pseudo locking. True locking happens when the intra-articular structure (e.g. ligaments) [1] is damaged, or a loose body is present inside the joint, or there is a meniscal tear. The knee can be unlocked by rotating the leg and full movement can be restored.
The leg extension is a good exercise for isolating muscular contraction in the quadriceps, [14] but as with all isolation exercises, should be included in a holistic resistance training program working all muscles, especially antagonistic muscle pairs (such as the quadriceps, hamstrings, and gluteal muscles), to avoid muscular imbalances, which ...
Genu recurvatum is a deformity in the knee joint, so that the knee bends backwards. In this deformity, excessive extension occurs in the tibiofemoral joint. Genu recurvatum is also called knee hyperextension and back knee. This deformity is more common in women [citation needed] and people with familial ligamentous laxity. [2]
Propulsion continues until the leg is extended behind the body and toe-off occurs. This involves a maximal hip extension, knee extension, and plantar flexion for the subject, resulting in the body being pushed forward from this motion, and the ankle/foot leaves the ground as the initial swing begins.
Both flexion and extension exercises have been shown to help mitigate back pain [8] and has been demonstrated to accomplish the following: a) significantly increase the canal area, b) increase the midsagittal diameter, c) increase the subarticular sagittal diameter, and d) increase all the foraminal dimensions significantly [9]
