Primary Outcome Measures:
  • Barthel Index [ Time Frame: Infusions are given over 3 weeks and subjects are followed-up at 1, 2 and 3 month intervals after the infusions ]

Secondary Outcome Measures:
  • Improvement in muscle strength and function [ Time Frame: Infusions are given over 3 weeks and subjects are followed-up at 1, 2 and 3 month intervals after the infusions ]
  • Change in the Mini-mental status examination [ Time Frame: Infusions are given over 3 weeks and subjects are followed up at 1,2, and 3 months after the infusions ]
  • Change in balance, coordination, range of motion [ Time Frame: Infusions are given over 3 weeks and subjects are followed-up at 1, 2 and 3 months after the infusions ]
  • Incidence of adverse events and changes in vital signs [ Time Frame: Infusions are given over 3 weeks and subjects are followed-up at 1, 2, and 3 months after the infusions ]

Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Magnesium infusion in patients breathing 100% oxygen
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).
Drug: Magnesium Chloride
An infusion of magnesium chloride will be given over 4 to 10 minutes in patients breathing 100% oxygen
Placebo Comparator: Placebo infusion
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.
Drug: Placebo
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

Detailed Description:
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.
