- Characteristics of sensory nerve fibres
| Sensory fibre | Myelinated axons | Diameter (µm) | Sensory information | Usefulness of electroneuromyography |
|---|---|---|---|---|
| Aα | Yes | 13-20 | Proprioception | Yes (H reflex) |
| Aβ | Yes | 6-12 | Discriminative sensitivity to mechanical stimuli (touch, vibration) | Yes (sensory nerve conduction) |
| Aδ | Yes | 1-5 | Sensitivity to cold and pain (“rapid”pain, pinprick) | No |
| C | No | 0.3-1.5 | Sensitivity to heat and pain ("slow" pain, burning sensations) | No |
