I have been told that locking one"s knees have the right to lead to fainting or passing out, and if you have to stand because that an extended period of time you should constantly avoid standing and not lock her knees.

You are watching: Can you pass out from locking your knees

I just did a bit of research study to check out if the same was true because that kneeling for an extended period of time, and some of what i read said that it"s a myth that locking one"s knees leader to fainting, it"s simply absence of motion in the legs, and kneeling have the right to have the very same effect.

Does locking one"s knees because that an extended duration actually lead to loss of awareness / pass out, and also if so, why?

Seth. You have actually "seen someone pass out from locking their knees". Just how do you understand it is the cause? Isn't is just a issue of "you have actually seen someone locking your knees and faint"?

Research shows that if the standard assumption is that knees are locked in standing, in reality in fact standing is possible with short leg stiffness without locking the knee. Medically, a knee is locked as soon as a torn part of the meniscus has displaced into a component of the knee or due to a tight Popliteus muscle.

The watch that "knee locking act alone by itself reasons syncope" is not backed up by clinical evidence. However, locking one"s knees and maintaining a rigid, fully unmoving standing position for long periods that time can interfere with ideal blood flow from the legs and cause vasovagal syncope.

It transforms out the clinical science behind “don’t lock your knees” doesn’t precisely hold up. While the advice to prevent locking knees is extensive – also outside the military communities – the actual cause of fainting is generally loss the blood flow to the mind which deserve to be carried on by any variety of things, yet the plot of locking persons knees has nothing to execute with pass out. If the plot of locking people knees and also maintaining a rigid, fully unmoving position for a long duration of time might interrupt proper blood flow, the action of locking the knees alone does no by itself reason fainting spells.

Syncope also commonly called fainting or “passing out” is a medical term used to explain a short-term loss of consciousness because of the sudden decline of blood circulation to the brain. If one is around to faint, there are a many accompanied symptoms described here. There are also several types of syncope which have specific trigger occasions or they it seems to be ~ to occur through other causes such as dehydration, BP medication and other clinical conditions. If that occurs very often there is no a triggering event, it might be a sign of an basic heart condition requiring medical attention.

Prolonged standing associated with warm or emotional tension can reason gravitational blood pooling in the lower extremities. This can act as a create for the fainting spell and also may be magnified by the knee locking.

“If dehydration is current the instance is worsened,” explains Dr. Richard Nicholas, chairman of the UAMS room of Orthopedic Surgery. “The low price of blood go back to the heart in these situations results in hypo-perfusion that the brain and at times the fainting spell. Standing at attention, or with one’s knees locked, may amplify the process.”

Medical advise to counter this knee locking mechanism is to move around or contract the leg muscles which might assist in stimulating the blood flow to the heart and improve circulation to the brain.
