For decades, blood pressure instability has silently debilitated people with spinal cord injuries—78% of those with cervical injuries experience dangerous drops when sitting upright, yet only 28% receive treatment that actually works. ONWARD Medical just enrolled the first participant in a pivotal trial testing whether an implanted spinal cord stimulator can solve this problem by restoring the autonomic signals that paralysis disrupts.
The Empower BP trial represents a new frontier for spinal cord stimulation technology. While epidural stimulators have already enabled paralyzed individuals to walk again in research settings, this study targets a less visible but equally life-limiting consequence of spinal cord injury: the inability to maintain stable blood pressure during everyday activities like sitting, eating, or physical therapy.

Scenarios
1
FDA Approves Implant for Blood Pressure, Opens New Market
Discussed by: Industry analysts covering ONWARD Medical; medical device market reports
If Empower BP meets its primary endpoints, the FDA could approve the ARC-IM system for blood pressure instability by 2028-2029. This would create a new treatment category for approximately 350,000 people in the US and Europe who experience this complication. Given ONWARD's track record with breakthrough designations and the ARC-EX approval, the regulatory pathway appears established. Success would validate the company's strategy of expanding from movement restoration to autonomic function recovery.
2
ARC-IM Becomes Multi-Indication Platform
Discussed by: ONWARD Medical investor communications; neurotechnology researchers
With 10 FDA Breakthrough Device Designations covering movement, blood pressure, trunk stability, bladder control, and spasticity, ONWARD could pursue additional pivotal trials for the ARC-IM implant. A single surgical implant addressing multiple complications would substantially increase the value proposition for patients and healthcare systems. The company's partnership with Ottobock and recent brain-computer interface licensing suggest this platform strategy is underway.
3
Trial Fails, Setback for Autonomic Therapies
Discussed by: Clinical trial analysts; medical device investors
Pivotal trials are inherently uncertain. If Empower BP fails to meet its primary endpoints—demonstrating statistically significant improvement in orthostatic hypotension management compared to sham stimulation—it would delay autonomic function treatments for spinal cord injury patients and potentially impact ONWARD's stock and ability to fund additional indications. However, the strong feasibility data showing two-year benefit durability reduces this risk.
4
Major Medical Device Company Acquires ONWARD
Discussed by: Medical device industry analysts; investment banking reports
ONWARD's proven regulatory pathway, multiple breakthrough designations, and first-mover advantage in spinal cord stimulation for paralysis make it an acquisition target for larger neuromodulation companies like Medtronic, Abbott, or Boston Scientific. The €50 million Ottobock investment at a 10% stake implies a valuation that could attract strategic interest, particularly if the Empower BP trial succeeds.
Historical Context
Deep Brain Stimulation for Parkinson's Disease (1987-1997)
1987-1997
What Happened
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.
Outcome
Short Term
Deep brain stimulation offered an alternative to brain lesioning surgery, with adjustable and reversible effects.
Long Term
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 It's Relevant Today
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.
Cochlear Implants Restore Hearing (1984-Present)
1984-present
What Happened
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.
Outcome
Short Term
Initial cochlear implants helped only profoundly deaf adults; children were not candidates until 1990.
Long Term
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 It's Relevant Today
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.
Spinal Cord Stimulation for Chronic Pain (1967-Present)
1967-present
What Happened
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.
Outcome
Short Term
Early spinal cord stimulators were crude and had high complication rates, limiting adoption.
Long Term
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 It's Relevant Today
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.
