I hear that you are aiming for the Robot vs. Human World Cup in 2050, but what you can’t do with robots at the moment is the “compensatory movement” action.
“Compensatory exercise” is an exercise that literally moves instead. If something goes wrong with your body, for example, even if your right knee is injured and it becomes difficult to move, you can run, walk, or move with a cane in a balanced manner. This is a very good person.
Robots that move joints with many motors have become more and more close to humans, and their cognitive and judgment abilities have increased, but if one motor breaks down, all of them freeze and become stuck. I’m not good at compensatory movements. However, the compensatory movement that makes a person injured and conscious will not be healed once the injury is healed, but the unconscious compensatory movement that appears in the movement by covering the painful part Many often remain as a habit.
For example, how to walk. The habit of walking is often not conscious of the person himself, and when he walks, he is often asked, “Do you have a backache?” Have you ever been told, “Tilt a little to the right, a little more …” when you take an ID photo?
If the muscle tension is not balanced somewhere, the shoulders will be lowered or the neck will be bent, and the way of walking and sitting will become habitual in an attempt to balance.
The unconscious compensatory movement is an exercise that tricks the brain into making it work as if it were working well. Although he thinks he is working well, there is a slight bias in his body. This difference in sensation appears in the patient’s symptom, “Why do I tend to have a backache?”
“Have you ever hurt your back?”
“No, not really”
“What kind of work do you do?” “Cook. It’s a standing job. Are you careful about how you stand?”
“The counter is low, so when I stand, I lean forward. My knees hurt from the evening.”
“Let’s check the balance by lying down. There is a difference in the length of the legs. The tension is strong on this side of the back. Stretch this leg. This is about the same length of the legs.”
“Is it so different?”
When the person unknowingly protects the pain and performs compensatory exercises for walking and standing, the tension of the entire muscles loses balance and the burden on the joints increases. Up to a certain point, the body naturally tries to regain balance, but when the same burden is applied every day, it tries to lighten the burden with an unnatural posture.
For this person, raising the cutting board on the countertop a little lessened the pain in the lower back and knees. Compensatory exercise is an excellent ability for humans to compete with robots, but it should not be overlooked that there are many chronic diseases and pains caused by it.
