Why is the selection of materials important in orthotic devices?

The selection of materials is crucial in orthotic devices because the materials chosen significantly influence both the durability and the functional capabilities of the device. Different materials possess unique mechanical properties, such as strength, flexibility, and resistance to wear, which directly affect how well the orthotic supports the user's needs. For instance, a material that is too rigid may not provide the necessary comfort or adaptability, while a very soft material may not offer adequate support. The performance of the orthotic in facilitating movement, correcting posture, or alleviating pain depends heavily on these material characteristics, making the careful selection of materials essential for effective orthotic fitting.

In contrast, while factors like color, weight, and production costs are relevant considerations, they do not have as direct an impact on the primary functional objectives of orthotic devices as the durability and functional properties associated with the chosen materials.
