Analysis of TCLT in TBI Patients: a Prospective, Randomized Controlled Trial
- Conditions
- Cognitive DeficitsBrain Injury
- Interventions
- Device: ShamDevice: Transcranial LED Therapy (TCLT)
- Registration Number
- NCT02393079
- Lead Sponsor
- University of Sao Paulo General Hospital
- Brief Summary
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).
- 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.

Group Intervention Description Sham group Sham 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. Active helmet LED Transcranial LED Therapy (TCLT) 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.
- Primary Outcome Measures
Name Time Method Evidence of improvement in inhibitory control measured by cognitive assessment (Stroop Test - Victoria Version) in patients undergoing intervention with an active LED helmet. 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.
- Secondary Outcome Measures
Name Time Method 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. 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.
