Arms
| Arm Name | Arm Description |
|---|---|
| Occipital nerve stimulation | Percutaneous quadripolar lead implanted under local anesthetic and mild sedation. Permanent neurostimulator implanted; stimulation at frequency of 50 Hz, pulse width 330 to 450 μs, maximum stimulation amplitude 10.5 V. |
| Sham occipital nerve stimulation | As above, but internal neurostimulator was inactive (turned off) |
