Fifteen individuals who sustained a TBI at least 12 months prior to study enrollment were identified as having abnormal GH secretion by glucagon stimulation testing (maximum GH response less than 8\u2009ng\/mL). Peak cardiorespiratory capacity, body composition, and muscle force testing were assessed at baseline and one year after rhGH replacement. Additionally, standardized neuropsychological tests that assess memory, processing speed, and cognitive flexibility, as well as self-report inventories related to depression and fatigue, were administered at baseline and 1 year after rhGH replacement. Comparison tests were performed with proper\n                    <jats:italic toggle=\"yes\">post hoc<\/jats:italic>\n                    analyses. All analyses were carried out at \u03b1 &lt; 0.05.

Cognitive performance did not change significantly over time, whereas self-reported symptoms related to depression and fatigue significantly improved. The observed changes suggest that rhGH replacement has a positive impact on cardiorespiratory fitness and a positive impact on perceptual fatigue in survivors of TBI with altered GH secretion.\n                  <\/jats:p>","DOI":"10.1089\/neu.2016.4552","type":"journal-article","created":{"date-parts":[[2016,9,14]],"date-time":"2016-09-14T10:30:01Z","timestamp":1473849001000},"page":"845-852","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":42,"title":["Functional Changes after Recombinant Human Growth Hormone Replacement in Patients with Chronic Traumatic Brain Injury and Abnormal Growth Hormone Secretion"],"prefix":"10.1177","volume":"34","author":[{"given":"Kurt A.","family":"Mossberg","sequence":"first","affiliation":[{"name":"University of Texas Medical Branch"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William J.","family":"Durham","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dennis J.","family":"Zgaljardic","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch"},{"name":"Transitional Learning Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles R.","family":"Gilkison","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher P.","family":"Danesi","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melinda","family":"Sheffield-Moore","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brent E.","family":"Masel","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch"},{"name":"Transitional Learning Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Randall J.","family":"Urban","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,2,15]]},"reference":[{"key":"e_1_3_3_2_2","first-page":"2752","article-title":"Prevalence of neuroendocrine dysfunction in patients recovering from traumatic brain injury","volume":"86","author":"Lieberman S.A.","year":"2001","unstructured":"Lieberman S.A., , Oberoi A.L., , Gilkison C.R., , Masel B.E., , and Urban R.J.
