The Claim
In patients with psoriatic arthritis, transcutaneous vagus nerve stimulation for five days was associated with a paradoxical increase in tumor necrosis factor-alpha (TNF-α) levels, despite concurrent reductions in C-reactive protein and disease activity, indicating complex or non-linear immune modulation.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
In people with psoriatic arthritis, a mild electric stimulation on the neck seemed to make one harmful immune protein go up, even though other signs of inflammation got better — which is weird and suggests the body’s immune system is responding in a complicated way.

What the research says
1 studyThe study found that a nerve-stimulating device reduced inflammation and joint pain in psoriatic arthritis patients, but it never measured TNF-alpha levels—so we can't say it went up. The claim says it did, but there's no proof.
