After a heart patient has received treatment, the medicines the patient receives usually make the patient have trouble standing up, walking, and keeping balance. This is often seen as a weakness caused by the heart condition. But the page author's experiments show another cause and how the cane helps the patient keep balance.
When the patient has no cane, the patient feels unsteady unless grasping a handrail or post. The railing or post provides the needed feel (and something to grab onto) for the patient feel stable. The patient otherwise feels the normal balance system in the semicircular canals of each ear is not providing the necessary information to achieve balance.
The human mind usually has an image of how balanced the body is. When the patient is having balance problems, the image is blurry. When the patient grasps something firm, the image is sharp.
When the patient has a cane, the patient feels unsteady only during the brief interval when the cane is raised to take a step. The cane provides the needed feel (and something to push with) for the patient feel stable. The patient otherwise feels the normal balance system in the semicircular canals of each ear is not providing the necessary information to achieve balance.
The human mind's image of how balanced the body is usually becomes sharp with the cane on the ground, even when the patient is not putting weight on the cane.
In some cases, the cane does not need to touch the ground. Holding it firmly out low in front of you can also give you balance information.
When using the cane, the page author noticed one thing about the normal information from the semicircular canals. The signal was not missing. It was LATE. The signal was late enough to not give the proper feedback to maintain balance. It gave no correction, then overcorrection.
The author also noticed that drinking more water reduced the delay, but didn't totally eliminate it.
