Which ergonomic measure can increase stability in fine hand work?

Answer and explanation

Correct answer: Providing proper support for hand or elbow

Fine hand work, such as writing, stitching, drawing, or assembling a small object, requires controlled and steady movements. If the hand or elbow has proper support, some of the arm’s weight is taken by the supporting surface. This reduces unnecessary muscle effort and shaking, allowing the fingers to make smaller, more accurate movements. Good support should be comfortable and should not force the wrist or shoulder into an awkward position. It is an ergonomic arrangement because it matches the task with the worker’s physical needs.

Option B is correct because supporting the hand or elbow improves stability, control, and precision. A shaking table in option A makes accurate work harder. Switching off the light in option C reduces visibility and may cause strain. Keeping tools far away in option D adds unnecessary reaching and movement. Ergonomics aims to make work safer, easier, and more efficient, so suitable support is the logical choice.
