Hemiplegic patient have a common gait deviation during their gait training is hyper-extension of knee or genu recurvatum.
Cause of genu recurvatum are,
1. weakness of platar flexors
2. flail foot
3. TA tightness
4. weakness in whole limb.
5. Poor trunk control and imbalance or low postural tone ( Down & hypotonic CP}
6. bigger step length of opposite unaffected leg.
u must be surprised to know that the cause is not quadriceps weakness.
most of the time the hyper extension is not because of quadriceps weakness.
In all above causes the patient is unable to keep the knee straight during weight bearing and they tend collapse with knee flexion. in order to prevent the knee collapse they lean forward and keep the line of gravity anterior to the knee.
In case of TA tightness it pulls the knee in hyper extension.
In order walk fast hemiplegic patients learn to take bigger step length of opposite unaffected leg. this cause riding of the femur over the fixed tibia causing hyper extension.
