Measure
Placebo Control
group of persons with spinal cord injury will receive blinded placebo capsule placebo: An ambiguous sheathing capsule will be placed over a lactose placebo pill. The placebo will have no effect on pulmonary function.
Active Drug
group of persons with spinal cord injury will receive blinded beta-2 adrenergic agonist capsule extended release beta-2 adrenergic agonist: Albuterol extended release belongs to a class of drugs known as bronchodilators. It works in the airways by opening breathing passages and relaxing muscles.
