This treatment study is a double-blind, placebo controlled trial designed to determine if treatment with recombinant human growth hormone (rhGH) in the sub-acute period after TBI results in improved functional outcome after injury and to determine if: treatment with rhGH results in increased IGF-1 levels; benefits of rhGH treatments persists up to 1 year after injury; low GH response to L-arginine stimulations at baseline is associated with poor functional outcome; low IGF-1 levels at baseline are associated with poor functional outcomes; rhGH treatment is more effective in patients who have low GH response to L-Arginine stimulation at baseline; and if rhGH treatment is more effective in patients who have low IGF-1 levels at baseline.
