Brief Summary:
The purpose of this study is to evaluate early and delayed effects of Transcranial LED Therapy (TCLT) and determinate whether this therapy is effective for cognitive rehabilitation of Diffuse Axonal Injury patients after Traumatic Brain Injury.

Condition or disease Intervention/treatment Phase
Diffuse Axonal Brain Injury Traumatic Brain Injury Device: Transcranial LED Therapy (Active coil helmet) Device: Transcranial LED Therapy (Inactive coil helmet) Not Applicable

Detailed Description:
This is a randomized clinical trial of patient with diffuse axonal injury (DAI) secondary to severe Traumatic Brain Injury in its acute stage (less than 8h). It will be recruited thirty adult patients who will receive thirty minutes at three times per week for 6 weeks (18 sessions) of transcranial stimulation. Fifteen of them will be stimulated with LED helmet and the rest with a sham helmet identical to the LED one, but only with a similar red light emission. Patient who meet inclusion criteria will be assessed with Glasgow Outcome Scale Extended (GOS-E) evaluation in at least five different periods (Admission, before and after each stimulation, and at 3 and 6 months later in outpatient followup).

Arms and Interventions

Arm Intervention/treatment
Active Comparator: Active Coil Helmet
The patients will undergo 18 sessions (627 nm, 70 mW/cm2, 10 J/cm2) at four points of the frontal and parietal region for 30 s each, totaling 120 s three times per week for 6 weeks, lasting 30 minutes of transcranial LED stimulation.
 Device: Transcranial LED Therapy (Active coil helmet)
The patients will undergo 18 sessions of repetitive transcranial LED stimulation.
Placebo Comparator: Inactive Coil Helmet
The patients assigned to this group will undergo 18 sessions of transcranial LED but with an inactive coil, which will not generate LED emissions.
 Device: Transcranial LED Therapy (Inactive coil helmet)
The patients assigned to this group will undergo 18 sessions of transcranial LED but with an inactive coil, which will not generate LED emissions, only a similar red light color.


Outcome Measures
Go to

Primary Outcome Measures :
  1. Improvement of early and delayed functional outcome measured by Glasgow Outcome Scale Extended (GOSE). [ Time Frame: Before stimulation and 1, 3 and 6 months after first stimulation ]
    Evaluation of improvement of early and delayed functional outcome measured by Glasgow Outcome Scale Extended (GOSE) after stimulation in comparison to the placebo group.


Secondary Outcome Measures :
  1. Improvement effects of transcranial LED in followup images measured by Marshall computed tomography scale and Adams grading scale for diffuse axonal injury. [ Time Frame: Before stimulation and 1, 3 and 6 months after first stimulation ]
    Evaluation of early and delayed effects of Transcranial LED Therapy (TCLT) to improve followup computed tomography or magnetic resonance of DAI patients after Traumatic Brain Injury, measured by Marshal computed tomography scale, Adams grading scale for diffuse axonal injury and a protocol published by Hamdeh et al. (doi: 10.1089/neu.2016.4426) which graduates the magnitude of diffuse axonal lesion.

  2. Hemodynamic improvement effect of transcranial LED measured by transcranial doppler (systolic and diastolic velocity of the left middle cerebral and basilar arteries, and the pulsatility index and resistance index values). [ Time Frame: Before stimulation and 1, 3 and 6 months after first stimulation ]
    Improvement evaluation of effects of LED therapy in hemodynamic change through transcranial doppler, measuring systolic and diastolic velocity of the left middle cerebral and basilar arteries, and the pulsatility index and resistance index values.
