The Effects of Transcranial LED Therapy (TCLT) in Patients With Traumatic Brain Injury (TBI): a Prospective, Randomized Controlled Trial

The purpose of this study is to evaluate the early and late effects of Transcranial Led Therapy (TLTC) in memory and executive functions in patients with moderate and severe TBI history (TBI time longer than 3 months).

Study Overview

Status

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

In the current study patients in the outpatient center - Neurotrauma Unit at University of São Paulo (HCFMUSP) diagnosed with moderate / severe blunt head trauma that meet the inclusion criteria will be divided randomly and blindly in two groups: Group A (n = 18) will receive stimulation through active helmet and Group B (n = 18) given placebo stimulation or sham through the inactive helmet. All patients will be subjected to 3 times of neuropsychological assessment: Study 1 (E1) - up to 4 weeks before the start of TLTC sessions; Study 2 (E2) - a week after the end of TLTC; and Study 3 (E3) - three months after the intervention. The evaluations will take in order to verify the early and late effects of TLTC in attention, memory and executive functions in patients with moderate and severe TBI.

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.

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. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Active helmet LED
Description of the intervention: 18 patients will undergo 18 sessions of transcranial LED therapy (ACTIVE HELMET) with 30 minutes duration each. The sessions take place over 6 weeks. The therapy will be performed with a helmet that covers the frontal and parietal region.
Device: Transcranial LED Therapy (TCLT)
Whereas the geometry of the skull and to uniformly distribute the light radiation, the TLTC is applied using as light source a set of LEDs installed in a helmet, emitting radiation in the range between 600nm and 650nm with a peak at 630nm, so in the red region.
Sham Comparator: Sham group
Description of the intervention: 18 patients will undergo 18 sessions of transcranial LED therapy (INACTIVE HELMET) with 30 minutes duration each. The sessions take place over 6 weeks. The therapy will be performed with a helmet that covers the frontal and parietal region.
Device: Sham
A SHAM identical helmet will be used in the control group.

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.
Outcome Measure
Measure Description
Time Frame
Evidence of improvement in inhibitory control measured by cognitive assessment (Stroop Test - Victoria Version) in patients undergoing intervention with an active LED helmet.
Time Frame: Three times: Up to one week before to start intervention, one week and three months after end the intervention
Measurement of each patient's inhibitory control by means of a test that causes them to cognitively suppress a habitual response in favor of a less habitual one. The results of patients with shorter response times indicate better positions in the tables, according to age. Examples of the average time (in seconds) of best results are between 17-29 years (11.79) and 80+ (19.31), any time longer than these indicates decreasing results.
Three times: Up to one week before to start intervention, one week and three months after end the intervention

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.
Outcome Measure
Measure Description
Time Frame
Assess the immediate and late effects of the intervention on victims of moderate or severe TBI in the following cognitive domains: executive functioning, attentional processes and memory.
Time Frame: Three times: Up to one week before to start intervention, one week and three months after end the intervention
Apply a neuropsychological assessment battery focused on executive functioning, attentional processes and memory to measure the effects of the active led helmet compared to the use of the sham device.
Three times: Up to one week before to start intervention, one week and three months after end the intervention
