Picture of the NIRS device placement. The light-blocking fabric overlay for the device was removed in all photos in this series to illustrate the location of the NIRS device on the forearm. (a) Palpation of the FDS. (b) Orientation of the NIRS probe directly on top of the palpated FDS. (c) The NIRS device secured to the forearm using a self-adherent wrap (Coban; 3M). NIRS = near-infrared spectroscopy; FDS = flexor digitorum superficialis.
