Brief Summary

Background: \- Traumatic brain injury (TBI) often causes problems with moving and balance, and thinking and emotions. Exercise can improve these things in people with other brain damage. Researchers want to look at the effect of exercise on these things in people with TBI. Objectives: \- To study how head injuries affect the brain. To study if exercise can help some symptoms in people with TBI. These include problems thinking, balancing, and moving, and depression or anxiety. Eligibility:

  • People age between 18 and 79
  • Had a non-penetrating TBI at least 12 months ago
  • Are physically inactive, but can stand and walk without help Design:
  • Participants will be screened with medical history, physical exam, and blood and urine tests. They may have a balance test.
  • Participants will be assigned to a high-intensity or a lower-intensity exercise program.
  • The study is 6 months long. There will be 3 months with exercise on an elliptical machine and 3 months without exercise.
  • Participants will exercise for 30 minutes on an elliptical machine, 3 days per week for 3 months.
  • Participants will also have 3 outpatient testing visits lasting approximately 8 hours, once every 3 months. This visit will include:
  • Blood tests
  • Tests for memory, attention, and thinking
  • Tests of walking and balance
  • Questionnaires
  • An MRI: they will lie in a machine that takes pictures of their brain, while breathing regular air and air with more carbon dioxide
  • Test of physical fitness

Outcome Measures

Primary Outcomes (1)

  • Change in Cognitive Function as Measured by Trail Making Test Part B (TMT-B)

    Trail Making Test (TMT) is a neuropsychological assessment of visual conceptual and visual motor tracking (involves motor speed and attention functions). Trail Making Test Part B (TMT-B) is associated with executive functioning and involves drawing a line connecting alternating numbers and letters in sequence (i.e., 1-A-2-B and so on). The time to complete the test is recorded. The time taken to complete the test was converted into standardized T-scores, representing a mean of 50 and a standard deviation of 10. Higher T-scores mean less cognitive deficits. The change in cognitive function was reported as the change in TMT-B T-scores across the 12 weeks (post minus pre intervention).

    Before (pre) and after (post) 12 weeks intervention

Study Arms (3)

Aerobic Exercise Intervention (AET)

EXPERIMENTAL

Participant with traumatic brain injury performed aerobic exercise on an elliptical trainer at a vigorous intensity for 30 minutes three times a week for 12 weeks

Other: Vigorous exercise

Rapid-Resistive Exercise Intervention (RET)

EXPERIMENTAL

Participant with traumatic brain injury performed rapid reciprocal exercise on an elliptical trainer at light to moderate intensity for 30 minutes three times a week for 12 weeks

Other: Light to moderate exercise

Waitlist Control (CON)

NO INTERVENTION

Participant with traumatic brain injury were waitlisted and did not perform any exercise intervention in the first 12 weeks. They were randomized to either AET or RET after the initial 12 weeks

Interventions
