Four clinical tests were used: the Schaeffer\u2019s, AIIMS, Szczecin 1 and Szczecin 2. Tendon visibility, the difficulty of distinguishing the PL from the flexor carpi radialis tendon, the number of attempts required for correct execution and the subjective ease of the test were analysed. The presence of the PL tendon was confirmed by ultrasonographic examination.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The sensitivity for the right hand was: Schaeffer\u2019s, 71%; AIIMS, 63%; Szczecin 1, 87%; Szczecin 2, 89%.
