The Effect of Aerobic Exercise on Mild Traumatic Brain Injury

June 25, 2015 updated by: US Department of Veterans Affairs

Aerobic Exercise in TBI: White Matter Integrity and Cognition

The current project will examine the effects of aerobic exercise on cognition among a group of veterans who have suffered a mild traumatic brain injury.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

There is substantial evidence that a large number of individuals who experience TBI will demonstrate life-long deficits in cognitive or social functions. An estimated 80-90,000 Americans with TBI suffer life-long impairment of physical, cognitive, and psychosocial skills to the degree that they are unable to return to school or work. Research on rehabilitation for mTBI has been minimal and typically has focused on speech, pain management, dizziness, fatigue, irritability, and sensory disorders. The results of the few studies that have examined long-term cognitive effects of mTBI have offered conflicting results. The current research will investigate the efficacy of an aerobic exercise intervention among individuals with mild traumatic brain injury (mTBI). This project will examine changes in fractional anisotropy (FA) values and cognitive functioning among individuals diagnosed with mTBI in a monitored aerobic exercise regimen, versus a low impact stretching and toning control group.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
24

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 50 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Anyone between 18 and 50 years of age,
  • from the geographic region served by the Malcolm Randall-North Florida-South Georgia VAMC,
  • who have sustained a TBI and demonstrate impairment on neuropsychological assessment (criteria for mTBI will be defined as a loss of consciousness for not more than 30 minutes and post-trauma amnesia of not more than 24 hours).

Exclusion Criteria:

  • TBI occurring less than 6 months or greater than 5 years prior to enrollment,
  • any metal implants or shrapnel that may put them at risk for injury during an MRI scan,
  • significant cognitive impairment (MMSE<24),
  • history of stroke,
  • B-12 deficiency,
  • hypothyroidism,
  • organ failure (renal, hepatic, cardiac, or lung),
  • substance abuse,
  • seizures,
  • or any limitation that would preclude them from safely engaging in the aerobic exercise regimen.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
