In this prospective observational study, we investigated the
time-dependent changes and correlations of upper arm performance
tests (ten-second test and Simple Test for Evaluating Hand Function
(STEF), the Japanese Orthopaedic Association (JOA) score, and the
JOA Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) in 31
patients with cervical myelopathy who had undergone surgery. We hypothesised that all the indices correlate with each other,
but show slightly different recovery patterns, and that the newly
described JOACMEQ is a sensitive outcome measure.Aims
