| Popis: | Background and Question Paired-pulse TMS (Transcranial Magnetic Stimulation) paradigms allow explore motor cortex physiology. The Triple Stimulation Technique (TST) improves conventional TMS in quantifying cortico-spinal conduction. The objective of our study was to compare both methods in paired-pulse paradigms of inhibition and of facilitation. Method We investigated paired pulse paradigms of 2 ms (short intra-cortical inhibition) and of 10 ms intervals (intra cortical facilitation) in a randomized order in 22 healthy subjects applying conventional TMS and the TST protocol. Results Paired-pulse paradigms by both TMS and the TST yielded comparable results of short intra- cortical inhibition and intra cortical facilitation. However, the coefficient of variation was significantly smaller for SICI paradigm using TST. Conclusion These results suggest no greater sensitivity of the TST for quantifying inhibition and facilitation. The utility of TST to better quantify the individual amount of inhibition in SICI paradigms and its clinical utility need further studies. |
