Brain zaps show promise for paralyzed arms – but study cut short
NCT ID NCT05390853
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a non-invasive brain stimulation method called tDCS, when added to standard physical therapy, could improve arm and hand function in people with recent spinal cord injuries. The trial included 13 participants with neck-level injuries who were between 3 and 6 months post-injury. The study was terminated early, so results are limited, but the goal was to see if this approach is feasible and effective for enhancing recovery.

Inclusion Criteria: * Traumatic SCI; * SCI neurological level, according to the American Spinal Injury Association (ASIA) definitions, from C3 to C7, included; * incomplete SCI (i.e. ASIA Impairment Scale: B, C or D); * distance from the SCI event: from 3 to 6 months; * residual motor ability of the target upper limb; * stable clinical conditions; * tolerance to sitting position for at least 45 minutes; * subjects capable and collaborating, able to give informed consent in person. Exclusion Criteria: * presence of implanted devices (e.g. pacemakers, intrathecal infusers, neurostimulators, hearing aids); * positive history of brain lesions; * presence of cerebral metallic implants (clips) or intracranial implants (e.g. ventriculoperitoneal shunt); * history of epilepsy or previous state of epileptic disease; * mechanical ventilation in place; * history of psychotic disorders; * history of severe neurodegenerative disease; * concomitant pre-existing clinical conditions that may interfere with movements of the target arm or hand (e.g. severe osteoarthritis, joint injuries, plexus injuries, peripheral nerve injuries, partial amputations); * use of antiepileptic drugs blocking Sodium o Calcium channels (e.g. Carbamazepine) or N-Methyl-D-Aspartate receptor antagonists (e.g. Dextromethorphan); * history of drugs abuse; * further contraindications to the use of TMS for PEMs elicitation (e.g. migraine with aura, permanent head / face tattoos); * presence of brain tumor; * pregnancy in progress.
