What factors could lead to orthotic failure?

A variety of factors can contribute to the failure of orthotic devices, but the combination of poor fit, lack of patient compliance, or improper use is particularly critical. A poor fit can lead to discomfort, skin irritations, and ineffective support, ultimately causing the patient to abandon the device. When patients do not comply with wearing instructions or engaging correctly with the orthotic, it diminishes the therapeutic benefits the device is meant to provide. Improper use, such as not wearing the device as prescribed or using it inappropriately, can also negate the effectiveness of the orthotic, leading to suboptimal outcomes and potential failure of treatment.

Various other factors may influence orthotic performance, like excessive weight or low-quality materials, but they do not capture the holistic interaction between the device, the patient, and the intended usage as effectively as the factors listed in the correct choice. Additionally, while design flaws can contribute to issues, they are just one aspect of the overall effectiveness and fit of the orthotic. The interplay between fit, compliance, and proper use is foundational to preventing orthotic failure and ensuring success in patient treatment.
