How does genu recurvatum affect gait?
Genu recurvatum is operationally defined as knee extension greater than 5′. Individuals who exhibit genu recurvatum may experience knee pain, display an extension gait pattern, and have poor proprioceptive control of terminal knee extension.
What causes genu recurvatum gait?
Genu recurvatum is a term that is used when one hyperextends their knee. Knee hyperextension can be caused by several causes. These include muscle weakness, especially of the muscles in the top of the thigh (quadriceps), it can be due to injury, or it can occur due to the shape of one’s bones at their knee.
What happens in genu recurvatum?
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 and people with familial ligamentous laxity.
Is genu recurvatum rare?
Genu recurvatum loosely translates as “backward-bending knee.” It is also known as congenital dislocation of the knee (CDK) or congenital dislocation of the patella (CDP), and sometimes as congenital hyperextension. CDK is a rare condition with an incidence rate of approximately 1 per 100,000 live births.
What causes extension thrust?
a reflex extension of the leg caused by applying a stimulus to the sole of the foot. The reflex normally occurs each time a person takes a step in walking or running, signaling a need for body support and providing the thrust for taking the next step.
How do you sleep with a hyperextended knee?
Elevation. Try to elevate your leg above your heart whenever possible. Lie in bed with your leg on a pillow or while relaxing in a recliner chair.
What is the definition of genu recurvatum syndrome?
Genu recurvatum is operationally defined as knee extension greater than 5′. Individuals who exhibit genu recurvatum may experience knee pain, display an extension gait pattern, and have poor proprioceptive control
How is knee hyperextension related to genu recurvatum?
Abnormal knee hyperextension during the stance phase (genu recurvatum) is a common gait abnormality in persons with hemiparesis due to stroke. While ankle-foot orthoses (AFOs) are often used to prevent genu recurvatum by maintaining ankle dorsiflexion during the stance phase, AFOs reduce ankle joint mobility.
How is functional electrical stimulation used to treat genu recurvatum?
Functional electrical stimulation (FES) is an alternative to the use of AFO for producing appropriately timed ankle dorsiflexion and with prolonged timing may also have value for reducing genu recurvatum. Case Description: A 51-year-old man with chronic strokewas the subject of this case study.
