@bolso1 "what TTNS stands for"
T = Transdermal = through the skin. So TTNS = *T*ransdermal electrode patch (no needle) to send a mild adjustable electrical signal through the skin to the *T*ibial *N*erve to *S*timulate it. So TTNS = Transdermal Tibial Nerve Stimulation. That stimulation, for reasons I'm not very clear on, has quite notably reduced nocturia. So basically a method for Tibial Electrical Nerve Stimulation that doesn't require a medical professional with scary needles now and then. Instead we can do it at home, as often as desired, balancing our comfort level vs effectiveness.
It may not work for everyone, and I've found the pad placement required a bit of experimentation - especially on the ankles where Tibial nerves pass close to the skin. In my case the Sacral nerve placement worked notably better, on an easier to find (though initially more difficult for self-placement).
If you spring for the $25 little black 9v analog TENS box to try it, you might consider having a medical professional find and mark your Tibial and Sacral placement points for the two pads (on each ankle for Tibial). I found that helpful as a starting point, then moved them around noting effectiveness for slight further improvement. Having grown used to the tingling, I can now turn the power to max right after placing the pads. Of course nothing helps if I don't stop liquids at least 4 hours before bed.
Hope this helps, and that you'll feel free to ask anything further. 🙂

Thank you. Here’s some information that I got through Lumo (AI assistant):
Transdermal Tibial Nerve Stimulation (TTNS) and Overactive Bladder
Overactive bladder (OAB) is characterized by urinary urgency, often accompanied by frequency and nocturia, with or without urge incontinence. Treatment typically follows a stepped approach—lifestyle modifications, behavioral therapy, pharmacotherapy (antimuscarinics, beta-3 agonists), and then neuromodulation therapies.
What Is TTNS?
Transcutaneous/Transdermal Tibial Nerve Stimulation (TTNS) is a non-invasive neuromodulation technique that delivers electrical stimulation to the tibial nerve via surface electrodes placed near the ankle. This is distinct from Percutaneous Tibial Nerve Stimulation (PTNS), which uses a needle electrode inserted near the nerve.
The tibial nerve originates from the sacral nerve roots (S2–S4)—the same roots that innervate the bladder and pelvic floor muscles. The therapeutic rationale is that stimulating this nerve modulates the sacral reflex arcs involved in bladder control, thereby reducing detrusor overactivity.
How It Works
Surface electrodes are placed on the skin over the posterior tibial nerve at the medial ankle.
Electrical impulses are delivered, typically at parameters around 10–200 Hz frequency with adjustable intensity.
Patients can self-administer treatment at home (a significant advantage over PTNS).
Treatment protocols generally involve sessions lasting 20–30 minutes, performed several times per week or daily depending on the protocol.
Evidence Base
Based on my training data, the evidence for TTNS is moderate but growing:
Multiple randomized controlled trials and systematic reviews have demonstrated meaningful improvements in OAB symptoms (urgency, frequency, nocturia, and incontinence episodes) compared to sham stimulation.
TTNS appears to be less effective than PTNS in head-to-head comparisons, which makes sense given that surface stimulation provides less precise nerve targeting. However, the convenience and non-invasive nature of TTNS are significant advantages.
Effect sizes tend to be moderate—improvements in symptom scores and quality of life measures are clinically meaningful but may not eliminate symptoms entirely.
Some studies suggest TTNS can be particularly useful as an adjunctive therapy alongside behavioral interventions and/or medication.
Advantages
Non-invasive: No needles, no implantation surgery
Self-administered at home: Greater convenience and lower cost than clinic-based PTNS or sacral neuromodulation
Favorable safety profile: Mild side effects mainly limited to skin irritation at the electrode site
No systemic drug side effects: An alternative for patients who cannot tolerate antimuscarinic medications (dry mouth, constipation, cognitive effects)
Limitations
Variable efficacy: Not all patients respond, and predictors of response are not well-established
Requires adherence: Home-based treatment requires patient commitment to regular sessions
Less robust evidence compared to PTNS and sacral neuromodulation in some comparative studies
Time to effect: Weeks of consistent treatment may be needed before symptomatic improvement is noticed
Where It Fits in the Treatment Pathway
TTNS is generally considered an option for patients who have failed or are intolerant to first-line treatments (behavioral therapy and pharmacotherapy) but who either decline or are not candidates for more invasive neuromodulation (sacral nerve stimulation) or botulinum toxin injections.
Important caveat: This is an educational overview based on my training knowledge, which has a cutoff in early 2024. Clinical guidelines and the evidence base may have evolved since then. If you're considering TTNS for yourself or someone else, I'd recommend consulting a urologist or urogynecologist who can provide personalized advice based on the latest clinical evidence and your specific situation.
