Effects of C1-C2 SCS on excitatory responses of lumbosacral spinal neurons to noxious colorectal distension (CRD, 60 mmHg, 20 s, n=18).
C1-C2 SCS | Spontaneous activity (imp/s) |
Latency (s) | Total responses (imp) |
Duration (s) |
---|---|---|---|---|
Before | 5.6±1.3 | 2.0±0.4 | 336.2±64.5 | 32.2±4.9 |
During | 3.9±1.1 | 2.3±0.6 | 225.0±73.3* | 25.3±6.6 |
After | 4.4±1.2 | 2.4±0.4 | 293.0±92.7 | 28.7±5.7 |
P<0.05 compared with corresponding activity of before SCS.
