After using a brain-computer interface training system, a patient regained the ability to scratch their nose and wipe their mouth. This shows that BCI training can restore specific voluntary movements in individuals with motor impairments.
See the scientific wording
Training with a brain-computer interface enables a patient to perform voluntary motor actions such as scratching the nose and wiping the mouth.

What the research says
4 studies reviewedSupporting (4)
Randomized Controlled TrialHuman2025
The study shows that brain-computer interface training helps stroke patients move their wrist better, but it didn't test if they can scratch their nose or wipe their mouth, so the claim is a bit too specific.
Randomized Controlled TrialHuman2023
This study found that BCI training helped stroke patients move their hands and arms better, which means they could likely do things like scratching their nose or wiping their mouth, even though the study didn't specifically test those actions.
Combined rTMS and Virtual Reality Brain-Computer Interface Training for Motor Recovery after Stroke
Randomized Controlled TrialHuman2018
The study shows that BCI training helps stroke patients move their fingers better, but it didn't test if they could scratch their nose or wipe their mouth, so the claim is a bit too specific.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.

- 1
We isolate the claim
Health advice from videos, articles and studies is broken down into single, testable claims.
- 2
We find the research
Each claim is matched against peer-reviewed studies, with every source cited by DOI.
- 3
We grade the evidence
Studies are scored on methodology, statistical rigor, transparency and publication quality.
The fitness and health internet is full of confident claims. We check them against real research.
Every claim on this site is traced back to peer-reviewed studies, scored on methodology and reporting quality, and given a verdict you can audit yourself — sources, DOIs and all.
