About this study
Official title: Effect of Fixed vs. Tailored Intensity Transcranial Direct Current Stimulation for Attention Deficit After Traumatic Brain Injury: a Single Center, Prospective, Double Blind, Randomized-Controlled Clinical Trial, Pilot Study
Traumatic brain injury (TBI) is an important global health concern. Recently, advances in neurocritical care have led to an increase in the number of recovering TBI patients, and concomittantly in the incidence of complications of TBI. One of the most important sequalae of TBI is cognitive deficit, for which multimodal rehabilitation approach is indicated. Transcranial direct current stimulation (tDCS) is a promising treatment strategy for post-TBI cognitive deficits. However, a standardized tailored tDCS protocol is yet to be established for TBI patients. Therefore, this trial aims to 1) the efficacy of tDCS on post-TBI cognitive deficits, and 2) and optimized protocol of tDCS on post-TBI cognitive deficits via a three-arm double-blind, randomized controlled trial.
Read the detailed description
Traumatic brain injury (TBI) is an important global health concern. It is estimated that about 70 million individuals will suffer a traumatic brain injury (TBI) each year. Serious TBIs for hospitalization or death is at least 10 million annually. In 2006, Langlois et al reported that, 50,000 patients die directly from or complications related to TBI in the united states alone, and at least 5.3 million Americans suffer from long-term disabilities related to TBI.
Recently, advances in neurocritical care have led to an increase in the number of severe TBI patients recovering cognitive and physical function, eventually returning to independent life.
With the rising recovery rate of TBI patients, the number of complications of TBI is also rising. One of the most common sequalae of TBI is cognitive deficit. In 2004, Whiteneck et al reported that about 65% of patients who experienced moderate to severe TBI suffer from long-term cognitive deficit. Mild TBI patients show fewer and lighter symptoms of cognitive deficit. However, about 15% of patients suffer from persisting cognitive, emotional, behavioral, and physical disabilities after one year (Roe et al. Disabil Rehabil. 2009).
Common symptoms of post-TBI cognitive deficit are attention deficit, memory loss, and impaired cognitive proceessing (Salmond et al. Curr Opin Crit Care. 2005). Current treatment strategy of post-TBI cognitive rehabilitation constitute multimodal approach including "conventional" occupational therapy, computerized neurocognitive training (CNT), pharmacotherapy, and physical medicine.
Transcranial direct current stimulation (tDCS) is a treatment approach where direct current is applied transcranially, aiming to modulate local neuronal excitability. Previous researches have established that repeated tDCS is safe, cost-effective, and easily administered to various neurological disorders including TBI, stroke, Parkinsonism, Alzheimer's dementia, and multiple sclerosis.
Although cognitive improvements are reported, a standardized protocol of tDCS for TBI patients is yet to be established (Kang, J Korean Neurol Assoc. 2017). The repertoire of researches that studies the efficacy of tDCS on post-TBI cognitive deficits is limited, and further study is warranted to establish standardized protocol (Ulam et al. Clinical Neurophysiology 2015; Kang et al. Journal of Rehabilitation Medicine 2012; Sacco et al. Front. Behav. Neurosci. 2016; Lesiank et al. J Head Trauma Rehabil. 2014; Rushby et al. Neuropsych Rehabil 2020; Motes et al J. Neurotrauma 2020).
This trial aims to determine 1) the efficacy of tDCS on post-TBI cognitive deficits, and 2) and optimized protocol of tDCS on post-TBI cognitive deficits via a three-arm double-blind, randomized controlled trial. The hypotheses of this experiment are as follow:
- Sham group and actual stimulation group will show significantly different aCPT response time after 10 tDCS sessions.
- Within the actual stimulation group, tailored tDCS subgroup will show significantly better aCPT response time than conventional tDCS subgroup after 10 tDCS sessions.
- Patients with EEG biomarker change will show significantly better aCPT response time than those without.

What is being measured
The primary outcome is the main question the study is designed to answer.
Auditory Continuous Performance Test (aCPT) response time
The Auditory Continuous Performance Test (ACPT) screens for auditory attention deficits. In the test, patients are told that they will see or hear the numbers "1" or "2" and that they are to click the mouse when presented with a visual or auditory "1" and inhibit clicking when presented with a "2". The task is made more challenging by the shifting of modalities between the visual and auditory stimuli. Data are provided for over-all attentional functioning and response control, as well as separate visual and auditory attention and response control.
Measured: 6 weeks
Secondary outcomes (3)
Auditory Continuous Performance Test (aCPT) omission error, commission error
The Auditory Continuous Performance Test (ACPT) screens for auditory attention deficits. In the test, patients are told that they will see or hear the numbers "1" or "2" and that they are to click the mouse when presented with a visual or auditory "1" and inhibit clicking when presented with a "2". The task is made more challenging by the shifting of modalities between the visual and auditory stimuli. Data are provided for over-all attentional functioning and response control, as well as separate visual and auditory attention and response control.
Measured: 6 weeks
Computerized Neurocognitive Test (CNT)
- Digit span test: Digit span forward test follows the number played through the computer speaker as it is and a digit span backward test speaks in reverse.
- Verbal learning test: 15 target words are heard through the computer speaker, recalled in any order and the same target word is repeated five times. After listening to the target word five times, 15 new words are heard and then recalled for blocking and then the 15 target words are recalled again.
- Stroop test: 24 letters of "green," "blue," "yellow," and "red" and the corresponding colors are read as quickly as possible. Several tests consist of (A) reading black letters, (B) the test to read the color by presenting each color square, (C) the test to read letters that match the color of the letter, and (D) the test to read the color of the letter whose color that composes the letter does not match the letter. The response time is scored.
Measured: 6 weeks
Cambridge Neuropsychological Test Automated Battery (CANTAB)
CANTAB tests changes in neuropsychological performance and include tests of working memory, learning and executive function; visual, verbal and episodic memory; attention, information processing and reaction time; social and emotion recognition, decision making and response control.
- Reaction Time (RTI) Reaction Time provides assessments of motor and mental response speeds, as well as measures of movement time, reaction time, response accuracy and impulsivity.
- Rapid Visual Information Processing (RVP) A white box is shown in the center of the screen, inside which digits appear in a pseudo-random order, at the rate of 100 digits per minute. Participants are requested to detect target sequences of digits When the participant sees the target sequence they must respond by selecting the button in the center of the screen as quickly as possible. The level of difficulty varies with either one- or three-target sequences that the participant must watch for at the same time.
Measured: 6 weeks
