Rate of different types of mechanical sensitization responses in Aδ and C meningeal afferents following CSD
| Group | TH only | STH only | TH + STH | |||
|---|---|---|---|---|---|---|
| Aδ | C | Aδ | C | Aδ | C | |
| CSD | 2/9 (11) | 1/14 (7) | 2/9 (22) | 2/14 (14) | 3/9 (30) | 7/14 (50) |
| Control | 0/5 (0) | 1/7 (8) | 0/5 (0) | 0/7 (0) | 0/5 (0) | 0/7 (0) |
Data show rate (% of responses). Sensitization at the TH and STH levels were determined according to the calculation described in the Methods. Two-tailed χ2 tests revealed no significant differences in the rate of the sensitization responses exhibited by the Aδ and C-unit populations.
