Study summary

The purpose of this study is to compare the sensitivity of the DANA Rapid exam with the MACE cognitive score. The primary hypothesis is that the DANA Rapid exam will be more sensitive for detecting impaired cognitive performance than the MACE cognitive score in the setting of a clinical diagnosis of concussion at the point of injury in the combat setting. A secondary purpose of this study is to examine a serial performance on the DANA Rapid exam in those subjects diagnosed with a concussion. The secondary hypothesis is that the DANA Rapid exam will show improvements in performance during the recovery period after concussion.

Read the detailed description

In Operations Iraqi Freedom and Enduring Freedom (OIF/OEF), over 60% of combat casualties have been the result of explosive blasts, and many of these critical injuries involve trauma to the head. As a result, traumatic brain injury (TBI) has been deemed a "signature wound" of OIF and OEF. The symptoms of head injuries, particularly of concussion/mild TBI (mTBI), can be sever but subtle, suggesting that early and accurate diagnosis is paramount to a wounded warrior's appropriate medical care. Most first providers in the war theater are medics who could benefit from an improved diagnostic test to better identify service members with concussion/mTBI. The MACE cognitive test is heavily weighted towards memory, is not 100% specific, and does not preclude a diagnosis of concussion being rendered despite a score in the normal range. Thus, an objective test of neurocognitive function, such as the DANA Rapid, that can be rapidly administered in theater by a combat medic would be highly beneficial to accurate clinical diagnosis and timely treatment. The results of the present study will provide information on the predictive value of the newly developed DANA handheld computer in assisting in the diagnosis of concussion in service members who have been blast exposed. If the DANA Rapid exam proves to be equally or more accurate than the MACE in detecting cognitive deficits, these tests and the handheld computer will also contribute to improved health care for service members by minimizing the time between injury and diagnosis.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Concussed

    Subjects who are diagnosed with a concussion by a clinician will be assessed with the MACE and DANA Rapid every 24 hours for up to 72 hours post-injury.

    Device: DANA Rapid · Other: MACE

  • Active comparator
    Non-concussed

    Subjects will have been exposed to a potentially concussive event but be clinically evaluated and found not to have sustained a concussion. Control subjects from this arm will take both the MACE and DANA Rapid twice: once within 24 hours of potentially concussive event, and again on the day of return to duty.

    Device: DANA Rapid · Other: MACE

Interventions

  • DeviceDANA Rapid

    The DANA Rapid is a neurocognitive test self-administered on a small handheld computer. The DANA Rapid subtests measure simple reaction time, procedural reaction time, and reaction time sensitivity.

  • OtherMACE

    The MACE is currently the only standardized and Department of Defense-designated method for the initial evaluation of suspected concussion in military operational settings. The MACE documents the history of the injury-causing incident; assesses cognitive deficits in orientation, immediate memory, concentration, and delayed recalls; and involves a neurological screening by a clinician.

What researchers measure

Primary outcomes

  1. Sensitivity

    The primary hypothesis is that an abnormal score on the DANA Rapid will positively identify a greater proportion of concussed individuals than an abnormal cognitive score on the MACE would. Conversely, scores within normal range on the DANA Rapid should be able to rule out cognitive deficits more accurately than a normal score on the MACE

    Time frame: 72 hours from initial injury

Secondary outcomes

  1. Serial Performance

    The secondary hypothesis of the study is that scores on the DANA Rapid exam will improve over time as the subject recovers from concussion.

    Time frame: 72 hours from initial injury

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 6, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
