Ultrasound probe orientation and measurement. A probe placed perpendicular to the dorsum of the first metatarsocuneiform joint measures dorsal translation, representing vertical mobility (A). A probe placed perpendicular to the plantar side of the first metatarsocuneiform joint measures plantar gapping, representing mobility under weight-bearing (B). A probe placed perpendicular to the medial side of the first metatarsocuneiform joint measures medial gapping, representing horizontal mobility (C). The techniques of ultrasound measurements before and after sufficient force were applied to reach the soft tissue endpoints and no further bone movements. The distances before and after the application of force were recorded for dorsal translation (A), plantar gapping (B), and medial gapping (C)
