The Claim
In patients with Neuromyelitis Optica Spectrum Disorder (NMOSD) receiving Transcutaneous Electrical Nerve Stimulation (TENS) therapy, both the active treatment group and the sham (placebo) group demonstrate substantial pain improvement, indicating that placebo or non-specific factors significantly contribute to the observed pain relief.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When people with a nerve disease called NMOSD used TENS machines for pain, both those who got real treatment and those who got fake treatment felt less pain. This tells us that just thinking you're getting treatment can actually help reduce pain.
See the scientific wording
The substantial pain improvement observed in both active and sham TENS groups suggests that placebo or non-specific factors significantly contribute to pain relief in NMOSD patients undergoing TENS therapy
What the research says
1 studyThe study found that both patients who got real TENS and those who got fake TENS felt less pain, suggesting the improvement came partly from believing the treatment works rather than from the treatment itself.
