Abstract

Event Abstract Back to Event Using Transcranial Magnetic Stimulation as a valid tool to evaluate sports concussion. A systematic review with preliminary results. Brendan P. Major1*, Mark Rogers1* and Alan Pearce1* 1 Deakin University, Australia This systematic review analysed cortical excitability and inhibition, via transcranial magnetic stimulation (TMS), following sports concussion. The following electronic databases were searched between January and March 2014: PsycINFO, MEDLINE Complete, Psycarticles, Pubmed, Sport Discus, Web of Science, Science Direct, and Cochrane Library using the following inclusion criteria; human, peer reviewed articles published between years 1995 to 2014 in English, age range of 18-60 years, sustained a mild to moderate sports concussion, single pulse TMS outcome measures of motor evoked potentials (MEPs) amplitude and latency, cortical silent period (cSP), short-interval intracortical inhibition (SICI) and long-interval intracortical inhibition. Of the 667 search results 17 studies met the inclusion criteria. For short term (<12 days) 3 studies reported immediate increases in MEP threshold, amplitude and latency following concussion or mild traumatic brain injury. In one study, shortening of cSP was reported 10 days post concussion matched with one reporting and immediate increase following injury. These measures were associated with changes in cognitive performance. For long term investigations (>3 years) 3 studies reported MEP and cSP threshold changes, 4 studies reported lengthening in cSP duration, with one study reporting a reduction. Similarly, cognitive changes were associated with alterations in cSP duration. These results demonstrate the validity of TMS as an investigative tool in elucidating the neurophysiological consequences of a sports concussion and can be used alongside standardised cognitive testing batteries.
