What the trial was testing
The trial enrolled 3 patients with spinal muscular atrophy. The study was sponsored by Marco Capogrosso and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
Researchers followed patients through treatment and into recovery, tracking the outcomes that mattered most for the disease being studied.
What the results showed
Up to 180% strength gains in three adults with SMA from spinal cord stimulation.
Nature Medicine · 2025 · NCT05430113
These findings — that in three adults with SMA after 4 weeks of spinal cord stimulation — were published in the Nature Medicine and represent the headline result of the study.
Researchers tracked outcomes across 3 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with spinal muscular atrophy, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Spinal cord stimulation for SMA is still in development and not yet FDA-approved for this purpose. Three FDA-approved SMA medicines (nusinersen, onasemnogene abeparvovec, risdiplam) are available now. Ask a neurologist about approved options and whether you might qualify for a stimulation trial.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

CuidAME: Longitudinal Data Collection From Patients With Spinal Muscular Atrophy in Spain
The goal of this observational study is to set up a longitudinal data collection study to perform a long-term follow-up of SMA patients in a real-world setting, and to standardise and homogenize the data collection process for SMA patient's data. Treated and untreated patients will be followed based on the routine clinical practice schedule.
Interfacing With NeuroTechnology to Expand Neural Throughput (INTENT)
The goal of this clinical trial is to evaluate the safety and preliminary efficacy of an implantable device that records and stimulates different areas of the brain to allow adults affected by disabling paralysis (see Eligibility for more details) to control and receive feedback from assistive devices.
