What is a key consideration when fitting a lower limb orthosis?

When fitting a lower limb orthosis, understanding the patient's gait mechanics is essential. This consideration encompasses the way a patient walks, including their stride length, swing phase, and weight-bearing patterns. Properly assessing and addressing gait mechanics ensures that the orthosis provides the necessary support, stability, and alignment to facilitate a more functional and natural movement.

A thorough evaluation of gait mechanics allows the orthotic fitter to customize the orthosis to align with the patient’s specific movement patterns and goals. This tailored approach can greatly improve overall mobility and reduce the risk of complications or discomfort from the orthosis.

While factors like a patient's age and weight, shoe size, and level of pain tolerance can influence the selection and fit of an orthosis, they do not directly pertain to the core purpose of the device, which is to enhance gait dynamics and support functional activities. Thus, focusing on gait mechanics addresses the primary function of the orthosis itself.
