Our primary aim was to compare the accuracy of trainee palpation\u2010guided versus first\u2010attempt US\u2010guided needle placement. Our secondary aim was to describe the locations of inaccurate needle placement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Seven subjects each performed four needle placements (ECRL and ECRB, both palpation\u2010guided and US\u2010guided), totaling 28 placements into a cadaveric specimen. US\u2010guided needle placement was performed with one attempt after one live demonstration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      No palpation\u2010guided ECRL attempts were accurate while only two of the palpation\u2010guided ECRB attempts were accurate. First\u2010attempt US\u2010guided needle placement was significantly more accurate overall (64.3% vs. 14.2%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.020), and specifically for ECRL (71.4% vs. 0%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.025). Combining palpation\u2010guided ECRL and ECRB attempts, the needle was inadvertently placed in the extensor digitorum communis (50%), extensor carpi ulnaris (16.7%), and brachioradialis (16.7%). Both US\u2010guided ECRL\u2010intended errors involved placing the needle into the adjacent ECRB.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This study suggests that EMG needle placement into ECRL and ECRB by trainees may be more accurate with US guidance.
