Portable neuromodulation induces neuroplasticity to re-activate motor function recovery from brain injury: a high-density MEG case study.
Ryan C N D'Arcy, Trevor Greene, Debbie Greene and 11 others
PMID 33261623WHAT IT FOUND
A man with severe brain injury and a long-standing walking plateau stood for 20 minutes with minimal assistance after 14 weeks of physiotherapy plus tongue stimulation.
His sitting balance scores improved substantially. This is a single case, so it does not prove the device works.
Key findings
01Timed standing improved from under 2 minutes with moderate support to 20 minutes with minimal assistance over 14 weeks of treatment.
02Function in Sitting Test scores rose from a baseline range of 12-19 to 33, exceeding the 6.5-point threshold for clinical meaningfulness.
03MEG and EEG data showed significant changes in beta activation patterns in motor regions during the treatment period compared to baseline.

What it does not show
This is a single case report, so findings cannot be generalized to other patients. The participant and his wife were authors on the paper, introducing potential bias in reporting and assessment. The study did not separate the effects of the PoNS device from the continued intensive physiotherapy; both were delivered together during the treatment phase. There was no control group or blinding. The neuroimaging results are correlational and do not prove that the device caused the brain changes or the functional improvements.
Declared interests
The participant and his wife are authors on this paper. The device used (PoNS) is manufactured by Helius Medical Technologies. The study was supported by non-U.S. government research funding, but the involvement of the subject as an author is a significant conflict of interest regarding the objectivity of the outcome reporting.
The easy way to misread this
Do not interpret this as evidence that the PoNS device alone caused the recovery. The patient received intensive physiotherapy concurrently, and the study design cannot separate the contribution of the device from the therapy. Furthermore, this is a single case with known authorship bias, so it does not establish efficacy for the broader population.
