Double Dose 4-AP on Functional Recovery After Spinal Cord Injury

Recruiting now · Phase 1/Phase 2 · Has a placebo group

Conditions studied: SCI - Spinal Cord Injury

In brief

The purpose of this study is to test a strategy to potentiate functional recovery of lower limb motor function in individuals with spinal cord injury (SCI). The FDA approved drug, Dalfampridine (4-AP). 4-AP will be used twice-daily in combination of Spike-timing-dependent plasticity (STDP) stimulation and STDP stimulation with limb training.
