Final answer:
The concept of nerve interference refers to the idea that disruptions or abnormalities in the spinal nerves can lead to pain and abnormal neural activity in the body.
Step-by-step explanation:
The concept of nerve interference, as explained by Vernon, refers to some element of interference or initiation of pain in the spinal joints that can create secondary aberrant effects such as increases in motoneuron or sympathetic neural activity. This refers to the idea that disruptions or abnormalities in the spinal nerves can lead to pain and abnormal neural activity in the body. For example, if there is a issue with the spinal nerves in the intervertebral foramina (IVF), it can cause pain and abnormal activity in the surrounding spinal joints. This can then affect the motoneurons or sympathetic nervous system, leading to increased activity in these neural pathways.
