Voltage-Gated Sodium Channels Modulate Pain Sensitivity
Specific voltage-gated sodium channels (VGSCs) within sensory neurons are critical for pain signaling, with alterations in their function contributing to chronic pain states.
Physiological Reviews · 2019
Key Findings
- 01VGSCs are essential for the transduction of sensory stimuli, action potential generation, and neurotransmitter release in sensory neurons.
- 02Specific VGSCs (Na<sub>v</sub>1.1, Na<sub>v</sub>1.6, Na<sub>v</sub>1.7, Na<sub>v</sub>1.8, and Na<sub>v</sub>1.9) are expressed in adult sensory neurons and their unique properties dictate their role in pain signaling.
- 03Changes in VGSC expression and modifications contribute to sensory neuron sensitization in chronic pain.
- 04Genetic variants in certain VGSCs are linked to human pain disorders.
Application
Design takeaway
Designers should consider the physiological mechanisms of pain when developing products or systems that interact with users, particularly in contexts where pain or discomfort is a risk.
How to apply
When designing tools, interfaces, or physical products, consider how their use might impact nerve signaling and pain perception, especially for individuals with pre-existing pain conditions.
Project actions
- 01When researching human factors, consider the underlying biological mechanisms.
- 02Explore how physiological responses can be influenced by product design.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive review of a complex biological system.
- +Highlights genetic links to pain disorders.
Limitations
Directly measuring or manipulating VGSCs in a typical design project is not feasible. The focus would be on understanding their role and designing to accommodate or mitigate their effects.
Reliability & validity
The reliability and validity of this review depend on the quality and consistency of the primary research it synthesizes. The findings are generally well-established within the neuroscience community.
Think critically
How might an understanding of specific VGSC functions inform the design of adaptive interfaces or tools for individuals experiencing chronic pain?
Design Principles
"Design for physiological comfort by understanding and mitigating factors that contribute to pain signaling."
Understanding the role of VGSCs in pain provides a foundation for designing interventions that can modulate pain perception. This knowledge is crucial for developing more effective pain management strategies and for designing products or environments that minimize the risk of chronic pain development.
What This Means for Your Design
Certain tiny channels in our nerves, called sodium channels, are super important for sending pain signals. If these channels get messed up, we can end up with long-term pain, and sometimes people have genetic differences in these channels that make them more prone to pain.
How to use in your project
- 1.Reference this research when discussing the physiological basis of user comfort or discomfort in your design project.
- 2.Use the findings to justify design choices aimed at reducing pain or improving sensory experience.

Paragraph starter
Research into voltage-gated sodium channels (VGSCs) reveals their critical role in pain signaling, with specific channel subtypes (Na<sub>v</sub>1.7, Na<sub>v</sub>1.8, Na<sub>v</sub>1.9) being key players. Alterations in these channels can lead to chronic pain states, highlighting the importance of considering these physiological mechanisms in design to ensure user comfort and safety.
