What it does not show
The study reported only one patient, so the result cannot be generalised. The authors state that the small sample size limits generalizability. No follow-up was conducted, so long-term effects are unknown.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that pain scrambler therapy reduces degenerative gonarthritis pain. This report describes one patient, and the authors did not check long-term effects.
