Analysis of TCLT in TBI Patients: a Prospective, Randomized Controlled Trial

Not Applicable
Completed
Conditions
Cognitive Deficits
Brain Injury
Interventions
Device: Sham
Device: 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.

Primary Outcome Measures
NameTimeMethod
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
NameTimeMethod
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.
