Training Upper Limbs of Neurodiverse Children by Connecting Brain Activities to a Virtual Reality Based Game

University of Nebraska51 enrolled

Overview

This study is testing ways to help children with cerebral palsy (CP) improve how their hands work. Investigators want to see if brain activity using a virtual reality (VR) program can make their hands work better. The program is called Hand and Bimanual Intensive Therapy Virtual Reality (HABIT-VR). Investigators will compare how well HABIT-VR works to a simple VR program. In the study a VR game will be played and participants in the treatment group, will have hand muscles gently stimulated to help the joints move.

Dysfunction in sensory, perceptual, and motor systems can lead to movement impairment, resulting in limitations in functional activities for children with cerebral palsy (CP). These limitations may be due to deficits in motor planning and execution. Previous investigations suggest that running a camp that uses VR software based on hand-arm bimanual Intensive Training (HABIT) improves motor planning and execution deficits in children with CP. The purpose of this study is to 1) develop a VR-augmented BrainComputer Interface Neurofeedback (BCI-NFT) for upper extremity motor rehabilitation of children with CP that can reliably deliver cortically linked neurofeedback to their forearm muscles and 2) compare the impact of BCI HABIT-VR and HABIT-VR on cortical activity and upper limb function in children with CP. Children who are 6-17 years old will be eligible for this study. Before starting the study, upper extremity motor function will be assessed with a set of clinical tests. Children with motor planning and execution deficits will receive 40 hours of either HABIT-VR or standard BCI-HABIT-VR (4 hours per day, 5 days/week, for two consecutive weeks), during which performance of the tasks and their movements will be tracked through 3-D motion tracking of the VR system. Two assessment sessions, before and after each camp, will be conducted to examine the outcome. The functional outcomes include Assistive Hand Assessment (AHA) to measure upper limb function, Box and Block Tests (BBT) to measure upper limb dexterity, and EEG recordings to measure changes in the cortical activity.

Brain-Computer Interface (BCI)-HABIT-VRDEVICE

Recent research indicates that running a camp using virtual reality (VR) software designed for a technique called hand-arm bimanual Intensive Training (HABIT) can help improve movement planning and execution in children with cerebral palsy (CP). In this study, investigators aim to combine brain activity monitoring (known as Brain-Computer Interface Neurofeedback, or BCI-NFT) to aid the rehabilitation of upper limb movements in children with CP. Furthermore, this new VR system (BCI-HABIT-VR) effects on brain activity and arm movement skills will be compared to the traditional HABIT-VR program.

Hand and Bimanual Intensive Therapy Virtual Reality (HABIT-VR)DEVICE

Participants will engage in a virtual reality (VR) game designed to train upper limbs. A wristband, called the Empatica E4, will be worn which will help measure various factors such as heart rate, sweat levels, and skin temperature. Additionally, the upper limb movements during the game will be measured. There will be no brain activity recording for this group.

Outcomes

Primary Outcomes

Assisting Hand Assessment

The Assisting Hand Assessment (AHA) is scored from 0 to 100 AHA-units, with higher scores indicating greater ability in using the affected in bi-manual tasks.

Time frame: From enrollment to the training sessions over two weeks and two assessment sessions within one week before and after the treatment

Brain Cortical Activity Measurement by Waveguard Electroencephalogram Cap

Changes in a participant's brain cortical activity will be measured during the intervention using a an FDA-cleared WAVEGUARD (TM) EEG Cap and an eego amplifier.

Time frame: Baseline (first assessment session) to 2 weeks

Secondary Outcomes

Box and Block Test Time

The Box and Block Test Time (BBT) will count the number of aparticipant can transfer from one compartment of a divided box to the other within 60 seconds. More blocks indicates better hand function.

Time frame: From enrollment to the training sessions over two weeks and two assessment sessions within one week before and after the treatment.
