What this trial studies

This study aims to enhance lower limb motor function recovery in individuals with spinal cord injury (SCI) by using the FDA-approved drug Dalfampridine (4-AP) in conjunction with Spike-timing-dependent plasticity (STDP) stimulation and limb training. The approach combines pharmacological treatment with targeted exercise to promote neuroplasticity and improve rehabilitation outcomes. Participants will undergo training designed to elicit STDP while receiving either the active drug or a placebo. The hypothesis is that this combination will lead to greater improvements in motor function compared to standard rehabilitation methods.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-85 with spinal cord injuries at or above L2, who can perform small muscle contractions.

Not a fit: Patients with uncontrolled medical conditions, significant cognitive impairments, or a history of seizures may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve mobility and quality of life for patients with spinal cord injuries.

How similar studies have performed: Previous studies have shown positive effects of Dalfampridine on motor function rehabilitation in chronic SCI, suggesting potential for success with this combined approach.
