The Effect of Exercise on Mood After Traumatic Brain Injury

The Effect of Exercise on Mood After Traumatic Brain Injury

We proposed to examine the effect of an aerobic exercise intervention on depression in persons with Traumatic Brain Injury (TBI). We will compare persons with chronic brain injury who are assigned to receive the exercise intervention with those in the control group to determine the effect of exercise on levels of depression and specific symptoms related to depression including anxiety, pain, sleep, and cognition. In addition, the effect of exercise on activity, participation level, and quality of life will be examined.

HYPOTHESES:

1. Participation in an aerobic exercise intervention will decrease the severity of depression in persons with chronic TBI.
2. Participation in an aerobic exercise intervention will lead to improvements in negative symptoms associated with depression including anxiety, insomnia, pain, and impaired cognitive functioning.
3. Participation in an aerobic exercise intervention will be related to improvements in activity and participation for patients with TBI.
4. Participation in an aerobic exercise intervention will lead to improvements in perceptions of quality of life.
