Where should the sternal pad be placed when fitting a hyperextension orthosis?

The sternal pad in a hyperextension orthosis is designed to provide the necessary support and control for the thoracic region, especially in conditions involving the spine. Placing the sternal pad 2 inches below the sternal notch is correct because this positioning helps to create a point of pressure that effectively limits thoracic flexion while also ensuring stability and comfort for the wearer.

By positioning the pad below the sternal notch, the orthosis can effectively engage the sternum and create a leverage point that encourages proper spinal alignment in a hyperextended position. This anatomical alignment is crucial for the therapeutic goals of the orthosis, which include reducing pain, promoting healing, and preventing further injury.

Other options, such as placing the pad at the xiphoid or above it, may not provide the same level of effective leverage and may lead to discomfort or insufficient control of the thoracic region, which is why they are not considered appropriate placements in this context. Similarly, positioning the pad at the sternal notch would not achieve the desired effect of controlling the thoracic motion effectively.
