“…Selecting an instrument or a battery of tests for assessment of nerve outcomes requires knowledge of the clinical measurement properties of the potential test options. Ideally, the selected measurement should be reliable and be able to distinguish functional outcomes, measure change in clinical status, and predict the outcome of different interventions [ 21 , 23 , 26 , 30 – 32 ]. Based on principles of evidence-based practice [ 33 – 36 ], any outcome measurement [ 11 , 31 – 33 ], including those for peripheral nerve repair assessment, it is essential to know the psychometric [ 37 , 38 ] properties such as reliability, validity, and responsiveness [ 30 , 38 , 39 ].…”
