For a Philadelphia cervical orthosis, in addition to neck circumference, which measurement should be taken?

For a Philadelphia cervical orthosis, taking the measurement from the mandible to the sternal notch is crucial as it helps ensure that the orthosis fits properly around the neck and provides adequate support to the cervical spine. This measurement allows the practitioner to customize the height of the orthosis so that it stabilizes the head and neck effectively while remaining comfortable for the patient. Proper fit is essential to prevent slippage and maximize the therapeutic benefits of the device.

The other measurements provided, while possibly relevant for different orthotic devices or for specific adjustments, do not serve the same purpose in relation to the Philadelphia cervical orthosis. Accurate sizing is key to achieving the right alignment and support, and the mandible to sternal notch measurement is particularly effective for achieving this in the context of cervical orthotics.
