Blood pressure instability has long burdened people with spinal cord injuries. Among those with cervical injuries, 78% experience dangerous drops when sitting upright, yet only 28% receive effective treatment. ONWARD Medical just enrolled the first participant in a trial testing whether an implanted spinal cord stimulator can restore the autonomic signals that paralysis disrupts.
The Empower BP trial applies spinal cord stimulation technology to a new problem. While epidural stimulators have already enabled paralyzed individuals to walk again in research settings, this study targets a less visible but serious consequence of spinal cord injury: the inability to maintain stable blood pressure during everyday activities like sitting, eating, or physical therapy.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1 of 3
1987-1997
Deep Brain Stimulation for Parkinson's Disease (1987-1997)
French neurosurgeon Alim-Louis Benabid discovered that high-frequency electrical stimulation of the thalamus could suppress tremors in Parkinson's patients. Medtronic commercialized the therapy, which received FDA approval in 1997 for essential tremor and 2002 for Parkinson's disease.
Then
Deep brain stimulation offered an alternative to brain lesioning surgery, with adjustable and reversible effects.
Now
DBS became standard of care for advanced Parkinson's, with over 200,000 patients treated. It established the business model and regulatory pathway for implantable neurostimulation therapies.
Why this matters now
ONWARD's spinal cord stimulators follow the same translation pattern: academic discovery, breakthrough device designation, pivotal trials, FDA approval, and commercialization by a specialized company. The DBS precedent shows how neurostimulation can evolve from experimental to standard of care over 10-15 years.

1984-present
Cochlear Implants Restore Hearing (1984-Present)
The FDA approved the first cochlear implant in 1984, enabling deaf individuals to perceive sound through direct electrical stimulation of the auditory nerve. Early devices provided limited benefit, but decades of refinement dramatically improved outcomes.
Then
Initial cochlear implants helped only profoundly deaf adults; children were not candidates until 1990.
Now
Over one million people worldwide now use cochlear implants. Most deaf children in developed countries receive implants, and many achieve near-normal language development. The technology created a multi-billion dollar industry.
Why this matters now
Like cochlear implants, spinal cord stimulation for paralysis replaces lost neural function with electrical signals. The cochlear implant trajectory—from crude early devices to sophisticated systems that restore near-normal function—suggests what may be possible as spinal cord stimulation technology matures over the next two decades.

1967-present
Spinal Cord Stimulation for Chronic Pain (1967-Present)
Norman Shealy implanted the first spinal cord stimulator for chronic pain in 1967, based on the gate control theory that electrical stimulation could block pain signals. Medtronic, Boston Scientific, and Abbott developed commercial systems that now represent a multi-billion dollar market.
Then
Early spinal cord stimulators were crude and had high complication rates, limiting adoption.
Now
The global spinal cord stimulation market reached approximately $2.5 billion annually, with devices implanted in hundreds of thousands of patients for failed back surgery syndrome and other chronic pain conditions.
Why this matters now
ONWARD's technology repurposes the same basic approach—epidural electrical stimulation—for a fundamentally different goal: restoring function rather than blocking pain. The established supply chains, surgical expertise, and reimbursement frameworks for pain stimulators provide infrastructure that could accelerate adoption of function-restoring stimulators.
