The finger-nose test. Extend the arm at shoulder level out to your side. With your eyes shut, swing you arm back in front of you and in, and touch your nose with your index finger. A person who has lost proprioception in the legs can maintain balance using their eyes, but falls over in the dark. Please let me know your experience or findings.
Proprioception seems to involve certain parts of the sensory nervous system.
The person lost all feeling from the neck down and the usual prognosis was to be relatively immobile for the rest of their life. He could not feel or control his limbs. This is what this person learnt to do, and against all expectations, he can now move with a 'normal appearance'. He envisions what he wants his body to do, and with sheer will, he makes it do it, even though he is feeling nothing. OMA brains have to learn to use a different mix of the two than is 'normal'.
