Introduction

TENS (Transcutaneous Electrical Nerve Stimulation) therapy is a popular, drug-free method to relieve pain. Many people experience amazing initial results, but some notice that over time, the same settings feel less effective. This is a natural phenomenon known as tolerance.

Understanding how tolerance develops—and how to prevent it—can help you keep your TENS therapy effective for months or years.

What Is TENS Tolerance?

Tolerance happens when your nervous system adapts to repeated electrical stimulation. Essentially, your nerves get “used to” the sam

In the realm of pain management, TENS machines have emerged as a popular non-invasive solution, offering relief to countless individuals worldwide. However, amidst the acclaim, a lingering question persists: Can TENS machines make pain worse? Let's delve into this topic to unravel the truth behind the myths and misconceptions.

Understanding TENS Technology TENS, short for Transcutaneous Electrical Nerve Stimulation, operates on the principle of delivering mild electrical impulses to nerve fibers, effectively disrupting pain signals sent to the brain. According to Johnson and colleagues (1991), TENS therapy modulates pain perception by activating endogenous opioid systems.

Tailoring Intensity for Optimal Relief One of the most critical aspects of TENS therapy is the ability to customize the intensity levels. By adjusting the settings
