Why is measuring a patient's limb important during an orthotic fitting?

Measuring a patient's limb is crucial during an orthotic fitting primarily to ensure proper fit and alignment, which directly affects both comfort and function. An accurate measurement allows the orthotic fitter to create or select an orthosis that conforms to the unique shape and size of the patient's limb. If the fit is incorrect, it can lead to discomfort, increased pressure points, skin irritation, or even further orthopedic issues.

Proper alignment is equally important, as it helps to maintain the desired biomechanics while the patient is wearing the orthosis. This alignment ensures that the device supports the affected limb appropriately and works effectively to aid in mobility or stability, allowing the patient to perform daily activities with enhanced confidence and safety.

In contrast, factors such as fitting speed, cost estimation, or the patient's age do not directly contribute to the clinical effectiveness of the orthotic device. While they may play roles in the broader context of care or financial considerations, they do not replace the necessity for precise limb measurements to achieve the desired therapeutic outcomes.
