 In this study, it was found that exercise assessment and aerobic exercise training can help reduce concussion-related physiological dysfunction and improve cerebral blood flow auto-regulation. Of the 91 patients with post-concussion syndrome, PCs, 41 of them were able to return to their normal activities after participating in a progressive exercise rehabilitation program. The majority of participants in the physiologic PCs group, 77 percent, and the PCs group, 64 percent, were able to return to their normal activities. One patient who declined exercise rehabilitation was unable to return to his or her normal activities. These findings suggest that exercise assessment and aerobic exercise training may be beneficial for individuals suffering from PCs. This article was authored by John G. Baker, Michael S.
