Advances in neuroprosthetic management of foot drop: a review.

PMID 32213196WHAT IT FOUND
Peroneal nerve stimulation can improve foot clearance and walking speed in non-progressive conditions like stroke.
However, it does not replace conventional treatment, and commercial devices still struggle to adapt to muscle fatigue or varied real-world terrain.
Key findings
01Stimulation of the peroneal nerve during the swing phase improves foot clearance and walking speed, particularly in non-progressive conditions like stroke.
02Commercially available systems rely on open-loop control, meaning they deliver fixed stimulation that cannot adapt to muscle fatigue or changing walking conditions.
03Electrical stimulation is not a replacement for other treatments; it is intended to be used in combination with conventional rehabilitation to aid gait recovery.

What it does not show
This is a narrative review, not a systematic review or meta-analysis, so it does not pool effect sizes or formally assess the quality of the included studies. The review focuses on device architecture and technical performance, with limited discussion of patient-reported outcomes or cost-effectiveness. Most included studies tested devices on flat, level ground, which does not reflect the varied terrain patients encounter in daily life. The long-term therapeutic effects of these devices are not well established, as most studies measured immediate or short-term outcomes.
Declared interests
The work was funded by the Spanish Ministry of Economy, Industry and Competitiveness. The authors did not report any conflicts of interest.
The easy way to misread this
Do not assume these devices work equally well for all neurological conditions. The review notes that therapeutic effects are sustained in non-progressive conditions like stroke but tend to decrease in progressive conditions like multiple sclerosis as the disease advances.
