How Analyze was Used
“Each subject was imaged while sitting with the shoulder in neutral position and the forearm supinated. The forearm of the subject was placed on a custom-made table with the wrist in the neutral position. We used an ultrasound scanner (Acuson Sequoia C512, Siemens Medical Solutions, Malvern, PA, USA) equipped with a linear array transducer (15 L8; frequency = 8–14 MHz).”
“All images were evaluated using Analyze 11.0 software… After the initial and final frames of the motion were selected and reviewed, the median nerve was outlined manually using a continuous boundary trace just within the echogenic boundary of the nerve (Duncan et al. 1999). Area, perimeter, circularity and aspect ratio of a minimum-enclosing rectangle (MER) of the median nerve were calculated automatically.”
