81The purpose of this study is to evaluate the effect of six intravenous (IV) infusions of magnesium chloride versus placebo in patients who have residual muscle weakness from a stroke that occurred three months to four years ago.
The hypothesis being tested is that these six treatments will improve muscle weakness and lead to an improvement in functioning/activities of daily living as measured by the 100-point Barthel index, three months after their last treatment versus their baseline measure, and that the mean difference between the treatment and placebo groups of patients will be at least three points in this index.
An infusion of magnesium chloride will be given over 4 to 10 minutes in patients breathing 100% oxygen
A saline placebo will be given as an infusion (six infusions over a three week period) in a double blind manner with the active test agent
Patients will be given six infusions over three weeks. Each infusion will last between 4 and 10 minutes. They will then return to clinic in 1,2 and 3 months for the same tests (but no infusions will be given).
The patients will receive six placebo infusions after which they will return to clinic at one, two and three months. At the conclusion of the trial those patients who received placebo may elect to receive the active treatment in another (open label) trial that will begin shortly after this one concludes.
