Hypothesis (What We Suspect)

• Some patients, including the author, have observed that increasing stimulation intensity may extend the period of symptom relief and reduce the frequency of maintenance treatments.
• That could explain why some patients gradually increase the intensity over months or years.

What We Do Not Know

• We do not know whether repeated, long-term use of stimulation substantially above the levels used in purpose-designed OAB systems provides greater long-term benefit, increases long-term risk, both, or neither.
• We have not identified long-term studies designed to answer this question.

Why Might This Question Remain Unanswered?

• Answering this question is likely to require a long-term study involving many patients over many years.
• The results would benefit patients, physicians, researchers, and every manufacturer of tibial nerve stimulation systems—not just one company.
• Because the knowledge would become a public benefit rather than a competitive advantage, it may be difficult for any single manufacturer of a general-purpose TENS device to justify funding such a study.

Remember

• A knowledge-based decision considers both what we know and what we do not yet know.
• If you choose to increase stimulation intensity, do so thoughtfully.
• The goal is effective, comfortable, and consistent stimulation—not simply the highest tolerable intensity.
• Report persistent pain, numbness, burning, or other unexpected effects to your physician.
