Spinal Segment Afferents and Clinical Applications

Vocabulary and definitions related to spinal segment stimulation, neurotransmitters, and clinical outcomes for pain management and organ regulation.

Cervical afferents

The primary driver of headaches and migraine pathways; stimulation may drive vagal activation to help $HRV$ and stress, while triggering endorphins to buffer pain.

$T2$ to $T6$

A spinal region that regulates cardiac and pulmonary outflow; stimulation here releases Substance P and $CGRP$ to produce vasodilation and micro circulatory flush in heart and lung tissues.

Substance P

A chemical stimulated in the $T2$ to $T6$ region that, along with $CGRP$, produces vasodilation and helps calm airway hyperactivity via endorphins.

$$CGRP$$

Calcitonin Gene-Related Peptide; its modulation in the $T7$ to $T10$ region helps with visceral pain and produces vasodilation in the $T2$ to $T6$ region.

$T7$ to $T10$

The spinal region used to access the stomach, liver, spleen, and small intestine; often treated using BT step mode to normalize gut motility and bowel sensitivity.

$T11$ to $L2$

The key area for the adrenals and kidneys; stimulation in this region reduces visceral hypersensitivity and supports adrenal recovery in chronically stressed patients.

$L3$ to $L5$

A spinal region where deep stem mode helps modulate the lumbar plexus, providing vascular perfusion and endorphins for a strong analgesic effect on chronic low back myofascial guarding.

Dynorphins

Chemicals released along with endorphins when stimulating the $L3$ to $L5$ region to provide an analgesic effect and modulate the lumbar plexus.

$S2$ to $S4$

The region containing parasympathetic roots at the sacral foramina that regulate the bladder, bowel, pelvic organs, and pelvic floor.

Bluestin

A mode used for the $S2$ to $S4$ region to produce an analgesic effect, restore circulation, and help with bladder urgency or pelvic nerve pain.

Pudendal neuralgia

A severe pelvic nerve pain condition that can be supported by targeting the $S2$ to $S4$ region to restore muscle function and unlock locked-up pelvic floor tissues.

Lumbar plexus

A network of nerves directly modulated by stimulation of the $L3$ to $L5$ region to provide analgesia and vascular perfusion.

Visceral pain

Intense internal pain that can be managed by targeting the $T7$ to $T10$ region (visceral pain) or $T11$ to $L2$ region (visceral hypersensitivity).
