  2. Closed kinetic chain exercises - Wikipedia

    en.wikipedia.org/wiki/Closed_kinetic_chain_exercises

    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 ...

  3. Open kinetic chain exercises - Wikipedia

    en.wikipedia.org/wiki/Open_kinetic_chain_exercises

    Open chain exercises are postulated to be advantageous in rehabilitation settings because they can be easily manipulated to selectively target specific muscles, or specific heads of certain muscles, more effectively than their closed chain counterparts, at different phases of contraction.

  4. Williams Flexion Exercises - Wikipedia

    en.wikipedia.org/wiki/Williams_Flexion_Exercises

    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]

    Knee pain from poor biomechanics is the driver behind much of the knee issues seen by Shari Berkowitz, a biomechanist and founder of The Vertical Workshop, a studio in New York’s Westchester ...

  6. Calf raises - Wikipedia

    en.wikipedia.org/wiki/Calf_raises

    Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).

  7. Running - Wikipedia

    en.wikipedia.org/wiki/Running

    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.

  8. Posterior cruciate ligament injury - Wikipedia

    en.wikipedia.org/wiki/Posterior_cruciate...

    Some exercises to strengthen the quadriceps and hamstring muscles include leg curls, leg lifts, prone knee flexion with resistance band and knee extensions. Some stretches to help prevent injury to the posterior cruciate ligament include stretching of the hamstring muscles by extending the legs, toes pointing up, leaning forward until the ...

  9. Anterior interval release - Wikipedia

    en.wikipedia.org/wiki/Anterior_interval_release

    Anterior interval release (AIR) is a type of arthroscopic knee surgery performed to alleviate pain and associated symptoms caused by scar tissue (or fibrosis) accumulation in the anterior region of the knee, behind and under the knee cap (or patella), in a condition called arthrofibrosis.
