Reliability of single and paired pulse transcranial magnetic stimulation parameters across eight testing sessions

Abstract

Transcranial magnetic stimulation (TMS) is a popular method for measuring motor cortical excitability in healthy and clinical populations, and is often used as an outcome measure to explore changes following an intervention. It is therefore important that the reliability of these measures is extensively examined and demonstrated. Several studies have sought to explore this [1–5], and have typically included assessment of reliability across 2–3 sessions for the following measures: motor threshold (MT); TMS recruitment/input output (IO) curves; short interval intracortical inhibition (SICI); and intracortical facilitation (ICF).
