4-aminopyridine has been researched along with Brain Ischemia in 5 studies
Brain Ischemia: Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.

"The Walk-12 is a 12-question questionnaire that asks subjects to rate limitations of their mobility during the preceding two weeks on a 5-point scale (from 1= not at all to 5=extremely). For each visit, the Walk-12 score will be calculated by summing the 12 components and transforming into a scale with a range of 0 to 100. A higher score indicates a greater degree of limitation in walking. A negative change indicates an improvement in walking. 0 = no limitation in mobility to 100 extreme limitation in mobility.~Walk-12 Score = 100 * [(Mean of the 12 items) - 1]/(5-1)" (NCT02271217)
