Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Overall pain as determined by the log area under the curve (AUC) of 10 cm visual analogue scale (VAS) pain scores measured over all stimulated time points (after 1 h) on Day 1 combined with overall pain scores from Days 2, 3 and 4 | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The log AUC pain scores as measured by 10 cm VAS from Day 1 (0 to 8 h) only 2. Percentage reduction in unstimulated AU pain as measured by 10 cm VAS - calculation of baseline pain and pain at 5 and 30 minutes. A reduction of 20% will be classed as clinically important 3. Time stimulated pain relief (as measured by 10 cm VAS) is maintained at =20% from baseline scores: change in baseline score from baseline to 1, 2, 3, 4, 5, 6, 7 and 8 h 4. Pain when eating and drinking as measured by a Likert scale at the end of Days 2–4 5. Healing of lesion assessed by the clinician as healed, partially healed or unchanged at baseline and Day 5 6. Safety of devices as determined by reported adverse events during the study period 7. Stinging sensation upon first application measured using a rating out of 10 on site at first application | — |
