NCT06743763

Brief Summary

The study aims to explore whether the treatment using fNIRS-based neurofeedback training for children with attention-deficit/hyperactivity disorder (ADHD) is useful. Furthermore, the study hopes to evaluate whether the use of virtual reality (VR) technology will have an impact on the treatment's effectiveness. The program includes the following components: Participants will be randomly assigned to one of three intervention groups: the neurofeedback with virtual reality (VR) group, the 2D neurofeedback group (with no VR technology applied), and the VR without neurofeedback group. All participants will complete academic-related tasks in simulated lessons. Participants in the VR neurofeedback group will wear VR goggles and a neurofeedback device that measures blood oxy-hemoglobin levels in brain cortical tissue and provides feedback via visual images or auditory sounds to the participants. Those in the 2D neurofeedback group will use a computer to complete the tasks, with all other settings (e.g., neurofeedback settings) remaining the same. The VR without neurofeedback group will wear VR goggles to complete tasks, but without the neurofeedback component. All participants will complete a total of 16 training sessions over 8 weeks (twice a week), with each session lasting approximately 35 to 60 minutes. To investigate the intervention's effectiveness, children will be asked to complete a set of cognitive tests covering inhibitory control, attention, and working memory before the intervention (i.e., Time 1), immediately after the 8-week training (i.e., Time 2), and 2 months after the training (i.e., Time 3, a 2-month follow-up). The assessment will take around 1 hour and will be conducted at the laboratory at the University of Hong Kong. Additionally, parents and teachers will be asked to complete a questionnaire assessing children's behavior at home and at school at three time points.

Outcome Measures

Primary Outcomes (3)

  • Children's ADHD symptoms

    Parents will be asked to complete the Swanson, Nolan, and Pelham Version IV Scale (SNAP-IV) measuring children's inattentive, hyperactive and impulsive symptoms with a 4-point Likert scale (ranges from 0 to 3). The minimum total score is 0 while the maximum total score is 78, with a higher score indicating a higher level of inattentive, hyperactive and impulsive symptoms.

    Pre-intervention Assessment (within 4 weeks before the commencement of the intervention)

  • Children's ADHD symptoms

    Parents will be asked to complete the Swanson, Nolan, and Pelham Version IV Scale (SNAP-IV) measuring children's inattentive, hyperactive and impulsive symptoms with a 4-point Likert scale (ranges from 0 to 3). The minimum total score is 0 while the maximum total score is 78, with a higher score indicating a higher level of inattentive, hyperactive and impulsive symptoms.

    Immediate Post-intervention Assessment (within 4 weeks after the completion of the intervention)

  • Children's ADHD symptoms

    Parents will be asked to complete the Swanson, Nolan, and Pelham Version IV Scale (SNAP-IV) measuring children's inattentive, hyperactive and impulsive symptoms with a 4-point Likert scale (ranges from 0 to 3). The minimum total score is 0 while the maximum total score is 78, with a higher score indicating a higher level of inattentive, hyperactive and impulsive symptoms.

Study Arms (3)

fNIRS-NFT with VR

EXPERIMENTAL

The experimental group will receive 16 sessions of training, 1 hour each, conducted twice per week over a period of 8 weeks. A classroom setting will be stimulated using VR and participants will be asked to complete some academic-related tasks during the stimulated lessons. The sensor on the neurofeedback device worn by the participants will detect changes in the blood oxy-hemoglobin level in brain cortical tissue and feedback to the participants via visual images or auditory sounds from the computer. Through practice, participants will learn to manipulate their attention, presumably by altering brain activities.

fNIRS-NFT without VR

ACTIVE COMPARATOR

The fNIRS-NFT without VR (NFT-2D group) will receive 16 sessions of training, 1 hour each, conducted twice per week over a period of 8 weeks. A classroom setting will be stimulated via a computer screen and participants will be asked to complete some academic-related tasks during the stimulated lessons by pressing a remote controller provided. The sensor on the neurofeedback device worn by the participants will detect changes in the blood oxy-hemoglobin level in brain cortical tissue and feedback to the participants via visual images or auditory sounds from the computer. Through practice, participants hopefully will learn to manipulate their attention, presumably by altering brain activities.

Behavioral: fNIRS-based neurofeedback

VR without fNIRS-NFT

ACTIVE COMPARATOR

In the VR without fNIRS-NFT Training, we have designed a virtual reality classroom scenario modeled and children are asked to complete academic tasks in the VR setting but no neurofeedback will be provided.

Behavioral: Virtual Reality Simulated Classroom

Interventions

fNIRS-based neurofeedback is provided during a simulated classroom scenario where the child participants are asked to learn to regulate their attention based on the feedback provided by the fNIRS on the oxygenated haemoglobin level in their prefrontal cortex.
