| Measure | Pretest | Preconditioning | Posttest | Postconditioning | Analysis |
|---|---|---|---|---|---|
| MEP threshold | 5/10 responses elicit MEPs of 50 μV | 5/10 responses elicit MEPs of 50 μV | Change in percentage of stimulation output | ||
| MEP response | 1 mV response (10) | Stimulation output used during pre (10) | Comparison of pre and post MEP amplitudes | ||
| SICI | 1 mV response (15) | 80% of MEP threshold, 2 ms preceding test (15) | Adjusted 1 mV response (15) | 80% of MEP threshold, 2 ms preceding test (15) | Conditioning/test ratio |
| ICF | 1 mV response (15) | 80% of MEP threshold, 10 ms preceding test (15) | Adjusted 1 mV response (15) | 80% of MEP threshold, 10 ms preceding test (15) | Conditioning/test ratio |
| CBI | 1 mV response (10) | 5% below brainstem threshold, 5 ms preceding test over the ipsilateral cerebellum (10) | Adjusted 1 mV response (10) | 5% below brainstem threshold, 5 ms preceding test over the ipsilateral cerebellum (10) | Conditioning/test ratio |
| Right M1 MEP response | 1 mV response with contralateral pectoral over right M1; preactivation (15) | Adjusted 1 mV response over right M1; preactivation (15) | Comparison of pre and post MEP amplitudes for pectoral ipsilateral MEP response |
TMS measures of motor cortex and cerebellar excitability. For each measure, an explanation is given for the test and conditioning pulses and the analysis used. Unless stated otherwise, the coil was placed on the hot spot of the left motor cortex (M1). The numbers within parentheses indicate the number of TMS pulses.
