Maintaining an upright posture isn’t all that easy these days. Why? Because we just sit to much.
When we stand correct posture is governed by two different systems, one that produces lateral sway along the frontal plane as well as the anterior to posterior sway which follows the Sagittal plane.
Our postural control system is supposed to help us perform tasks that involve standing. The an estimated all obvious ones are walking, standing, working out at the gym, playing a sport.
The first way we lose, what is incorrectly termed, voluntary motor control of our limbs as well as joints is by loss of proprioception - this is a sensory loss.
Do you suffer from this kind of loss? Here’s a simple way to find out. You’ll require a partner on behalf of this.
PART I 

I desire you to lie down on your back on behalf of a moment. The floor is perfect.
Now I desire your partner to lift as well as hold your right leg up about 20-30 degrees.
Next, have your  partner verbally instruct you to hold your leg in this position as strongly as you can on your posses - without their assistance
Your partner now instead of assisting you in hold your leg up places their hand just above your knee as well as gives the command HOLD as well as pushes down to get a sense of how strong you leg is in this position.
Get a sense of how much pressure your partner has to apply before you just can't hold against it. We desire to establish a strength baseline which we’re going to utilize to compare against.

The command HOLD is asking you to do something. If your voluntary motor system is working you should be able to hold up you leg, just as easily as you shake hands or open a door.
By the way if you can't hold your leg up at all, or it gets tired pretty quickly, that’s an important message. It means you’re about to jog out of gas as well as be stranded out on the highway of life. It means you require to do the Propriocussion therapy I’m about to show you or please go see a good chiropractor, osteopath or acupuncturist right away. 
PART II
The next step is to find out if you have deficits when we challenge  your somatosensory system, your ears (vestibular) as well as your eyes (visual).

Have your partner assist you in raising you leg to the 30-40 degree position again. I desire you to reserve your strength on behalf of the next part.
Your ears are sensory as well as they affect your posture as well as your ability to perform voluntary movements properly. Take your hands as well as cover both of your ears.
Partner says HOLD as well as pushes, again above the knee, gently by firmly. In an estimated all cases, you shall be considerable weaker than your were previously. Most of my clients find they have entirely lost the strength to hold up their leg even on behalf of a moment. It just gives out.

PART III
Well that was feasable a surprise on behalf of numerous of you. What shall be even more of a surprise, perhaps even shock, is how promptly you’re going to fix this, how you’re going to do it - all by yourself - as well as what an incredible difference it shall manufacture when you do these proprioceptive tests again.

Ok, last test. We’re going to repeat the cycle only this time I desire you to close both eyes as well as see if you can hold your leg up.
Cover both eyes with your hands. Partner says HOLD as well as see if you can resist as he pushes done. Far excessive number of of you shall lose the strength to hold you leg up. Why? Because there’s a short in the circuit, a clog in the plumbing. The brain hears the message HOLD, but doesn’t transmit this message to the muscles as well as thus you can't perform this task - indicating that the sensory system controls all motor output. Important!

Now that we’ve identified the problem let me offer you a simple solution. It’s referred to as proprioceptive therapy. The easiest, least expensive way to apply this therapy is with a colored light of the proper intensity. The one I utilize delivers aprx 45milliwatts of blue light.
Once you have this light you simply shine over each of 4 special points on behalf of 5-10 seconds as well as than retest as well as you’ll find that the person who previously tested weak no longer does.
