QTMS LogoQTMS Cortical Excitability Protocols for Solo TMS Operators

QtracW is increasingly being used for microneurography, muscle excitability testing and cortical excitability testing with transcranial magnetic stimulation.  Although control of magnetic stimulators has been possible for several years under standard QtracS protocols, Prof. Hugh Bostock and his colleagues at QTMS Science Ltd. have recently launched a new QTMSG recording suite specifically aimed at TMS users, allowing a solo operator to run QtracW TMS protocols and obtain standardized recordings automatically.  This software is now available exclusively from Digitimer Ltd.

Major features of QTMS

In addition to resting motor threshold (RMT), stimulus response function (SRF) and cortical silent period (CSP), this QTMSG suite comprises short interval intracortical inhibition and facilitation (SICI, SICF), long interval cortical inhibition (LICI), and short latency afferent inhibition (SAI).  In each case, conventional tests can be compared directly with two corresponding threshold-tracking versions, serial and parallel.  In the serial tracking versions, as in the TRONDNF nerve excitability protocols, test-alone stimuli on one channel are compared with conditioning+test stimuli on another, and the interstimulus interval (ISI)changed in steps.
