What is the most appropriate way to secure the final adjustment of an orthosis?

The most appropriate way to secure the final adjustment of an orthosis is to ensure the patient is in a standing position. This position allows for the most accurate assessment of fit and function, as it closely mimics the way the patient will actually wear the orthosis during daily activities. Standing provides a better representation of the forces and pressure that the body will exert on the orthosis when ambulating or bearing weight.

In this position, any adjustments can be made based on how the orthosis interacts with the patient's anatomical landmarks and how it aligns with their gait mechanics. It allows practitioners to assess issues related to balance, comfort, and overall function effectively.

Other options, such as having the patient lay supine or using a mirror to check position, may not provide a comprehensive picture of the orthosis's performance in real-world conditions. While asking for the patient's comfort level is important for feedback, the standing position ultimately ensures that the orthosis supports the necessary stability and mobility required for daily activities.
