Cortical excitability is assessed by transcranial magnetic stimulation (TMS), a non\u2010invasive neurophysiological technique. The TMS biomarkers exhibiting highest sensitivity for cortical hyperexcitability in ALS remain to be elucidated.

Significant reduction of mean short interval intracortical inhibition (interstimulus interval 1\u20137\u2009ms) exhibited the highest standardized mean difference with moderate heterogeneity (\u22120.994, 95% confidence interval \u22121.12 to \u22120.873,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001;\n                      <jats:italic>Q<\/jats:italic>\n                      \u2009=\u200938.61,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05;\n                      <jats:italic>I<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u200940%).
