This study was big enough to detect a real difference in pain if one existed - it had over 90% power to find even a small 2-point improvement on the pain scale between real TENS and fake TENS treatment, so the finding of no difference isn't just because there weren't enough patients.

A transcutaneous electrical nerve stimulation device for the relief of neuropathic pain in NMOSD: A randomized, double-blind, sham-controlled trial
Randomized Controlled Trial
Human
2024 Oct-DecThe claim says the study had enough patients to detect a real difference (over 90% power), so the finding of no difference between TENS and sham treatment isn't just because there weren't enough people. But the study abstract doesn't mention anything about power calculations, so we can't verify this claim.
