PMID 28626338WHAT IT FOUND
In one woman with pain after shingles, 10 daily 40-minute pain scrambler sessions were followed by pain dropping from 7 to 1 on a 10-point scale and a quality-of-life score rising by 128 points, higher is better.
Single case, not proof.
Key findings

02The quality-of-life score, where higher means better, increased by 128 points after the 10 therapy sessions.

What it does not show
Only one woman was reported, so it describes one person, not a pattern. The authors state the sample size was small. The authors could not do follow-up to determine how long the effect lasted.
The easy way to misread this
Do not conclude pain scrambler therapy works for pain after shingles. Only one woman was reported, and the authors could not follow up to determine how long any change lasted.
