A person with carpal tunnel syndrome experiences numbness in their fingers. Which mechanism explains why using a specialized ergonomic keyboard reduces these symptoms?

💡 Explanation

Ergonomic keyboards reduce carpal tunnel symptoms because they promote a more neutral wrist posture, thereby decreasing the compression of the median nerve within the carpal tunnel. Therefore, the reduction in nerve compression alleviates the numbness, rather than directly affecting thermal receptors or skin mechanoreceptors.
