Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Numerical Rating Scale (NRS) at each of the following time points The NRS immediately before stimulation on day 1 is used as the baseline. Immediately after stimulation on days 1 and 5, and on day 12 | — |
Secondary
| Measure | Time frame |
|---|---|
| Magnitude of paired-pulse suppression in the inter-vertex amplitude of N20-P25 among the components of the somatosensory evoked potentials produced by stimulation of the median nerve on the painful side at 30 ms and 100 ms intervals at each of the following time points Immediately before and after stimulation on days 1 and 5 | — |
