| Outcomes of pain treatment | ||||
| Pain levels of 5 or more on a 0–10 pain scale | 2.00 | 2.61 | 83.3% (15) strongly agree/agree | YES |
| Less than 30% pain intensity reduction | 2.00 | 2.06 | 88.9% (16) strongly agree/agree | YES |
| No period of pain remission | 2.00 | 2.12 | 82.4% (14) strongly agree/agree | YES |
| An increase in pain severity | 2.00 | 1.78 | 77.8% (14) strongly agree/agree | YES |
| Quality of life remains significantly affected by pain (e.g. sleep, activity limitations, mood, disability) | 2.00 | 1.83 | 83.3% (15) strongly agree/agree | YES |
| Usefulness of other non-drug therapies | ||||
| Non-pharmacological therapies must be tried before neuropathic pain is considered refractory (e.g. TNS, physical therapy, psychological therapy, relaxation) | 2.00 | 2.58 | 63.2% (12) strongly agree/agree | NO |

*1 = strongly agree to 5 = strongly disagree, lower mean/ median score = higher agreement.
