Helius Announces FDA 510(k) Submission for PoNS® Device Label Expansion in Stroke
Rhea-AI Summary
Helius Medical Technologies (NASDAQ: HSDT) has submitted a 510(k) application to the FDA for its PoNS (Portable Neuromodulation Stimulator) device, seeking label expansion for treating gait and balance deficit in chronic stroke patients. The submission, filed under FDA Breakthrough Device Designation, is supported by the Stroke Registrational Program (SRP) data.
The clinical trials, involving 159 chronic stroke survivors across 10 sites, demonstrated that PoNS Therapy combined with physical therapy achieved a clinically meaningful improvement of over 5 points in the Functional Gait Assessment (FGA), compared to less than 4 points in the control group. The treatment effect was maintained for at least 12 weeks post-therapy, with 89.7% of subjects meeting durability goals. The device proved safe with no treatment-related serious adverse events.
Positive
- None.
Negative
- Berg Balance Score improvements did not reach statistical significance
- Risk of falling reduction was not statistically significant between groups

Seeking an indication for gait and balance deficit in patients with chronic symptoms of stroke under its Breakthrough Device Designation
NEWTOWN, Pa., Sept. 25, 2025 (GLOBE NEWSWIRE) -- Helius Medical Technologies, Inc. (NASDAQ: HSDT), today announced the filing of its U.S. Food and Drug Administration (FDA) 510(k) submission for the PoNS (Portable Neuromodulation Stimulator) device label expansion seeking an indication for gait and balance deficit in patients with chronic stroke symptoms. The submission was made with data generated in its Stroke Registrational Program (SRP) and was filed under its current FDA Breakthrough Device Designation.
All statistical analyses for the Functional Gait Assessment (FGA) primary endpoint demonstrated PoNS superior effectiveness in improving gait deficit by achieving a clinically meaningful mean improvement of more than 5 points, which was statistically significant across all studies (p<0.05) and was maintained for at least 12 weeks after completion of the therapy. Conversely the control group achieved, across all trials, a mean FGA improvement of less than 4 points, which fell below the 4.2-point Minimal Detectable Change (MDC) that reflects clinical meaningfulness of the therapeutic intervention.
“Substantial evidence across the SRP trials supports the superiority of active PoNS Therapy® as compared to physical therapy alone, when applied in standard clinical settings for stroke rehabilitation,” said Antonella Favit-Van Pelt, M.D., Ph.D., Helius’ Chief Medical Officer. “The totality of data in stroke survivors with gait deficits confirms the broader evidence of PoNS therapeutic effect in improving walking disability by enhancing and potentiating the benefit of physical therapy. Consistent with the existing body of clinical evidence, PoNS also confirms to be a safe and well tolerated therapy.”
PoNS efficacy and safety was clinically established from three clinical trials across 10 sites and 159 enrolled chronic stroke survivors with gait deficit due to stroke. The studies were structured to assess the effectiveness and safety of the PoNS device in conjunction with routine physical rehabilitation therapy over a 12-week treatment period. Participants were also followed for 12 weeks after completion of treatment to assess durability of treatment effect. Primary efficacy endpoints for gait (by FGA) and balance (by the Berg Balance Score), as well as key secondary endpoints including risk of falling (determined by FGA <23) and durability of effect (established at <
Overall, the primary endpoint was met and statistically significant for the FGA primary endpoint. In the primary analysis of the pooled pivotal randomized controlled and single-arm studies, treatment with active PoNS plus physical therapy (PT) led to an adjusted mean change in FGA of 5.37 points (
"Submitting our 510(k) application to the FDA brings the benefits on gait from PoNS Therapy one step closer to stroke patients," said Dane Andreeff, CEO of Helius. "I'm incredibly proud of our team and thankful to the clinicians who facilitated this trial as we work together to increase patient access to this powerful therapy. We’re optimistic about a positive FDA outcome and the opportunity to support those living with the effects of stroke."
About the PoNS Device and PoNS Therapy
The Portable Neuromodulation Stimulator (“PoNS”) is an innovative, non-implantable, orally applied therapy that delivers neurostimulation through a mouthpiece connected to a controller and it’s used, primarily at home, with physical rehabilitation exercise, to improve balance and gait. The PoNS device, which delivers mild electrical impulses to the tongue, is indicated for use in the United States as a short-term treatment of gait deficit due to mild-to-moderate symptoms from MS and is to be used as an adjunct to a supervised therapeutic exercise program in patients 22 years of age and over by prescription only.
PoNS has shown effectiveness in treating gait or balance and a significant reduction in the risk of falling in stroke patients in Canada, where it received authorization for sale in three indications: (i) for use as a short-term treatment (14 weeks) of gait deficit due to mild and moderate symptoms from stroke and is to be used in conjunction with physical therapy; (ii) for use as a short-term treatment (14 weeks) of chronic balance deficit due to mild-to-moderate traumatic brain injury (“mmTBI”) and is to be used in conjunction with physical therapy; and (iii) for use as a short-term treatment (14 weeks) of gait deficit due to mild and moderate symptoms from MS and is to be used in conjunction with physical therapy. PoNS is also authorized for sale in Australia for short term use by healthcare professionals as an adjunct to a therapeutic exercise program to improve balance and gait.
