Virtual Reality Walking for Traumatic Brain Injury
(fNIRS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new method to study brain activity in individuals with long-term traumatic brain injuries (TBI). It employs a special device called functional near-infrared spectroscopy (fNIRS) to safely monitor brain signals while participants walk on a treadmill with virtual reality (VR) visuals. The researchers aim to determine if this setup is safe and effective for data collection. Suitable candidates have experienced moderate to severe TBI, completed inpatient rehab, and continue to have balance issues. As an unphased trial, this study provides a unique opportunity for participants to contribute to innovative research that could enhance future TBI treatments.
Do I need to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this device is safe for use in individuals with chronic TBI?
Research has shown that the functional near-infrared spectroscopy (fNIRS) device is safe for people. In a previous study, all participants handled the procedure well, and 87.5% found it acceptable. FNIRS is non-invasive, meaning it doesn't require surgery or use radiation, making it a safe choice for checking brain activity. Researchers have used the device to study brain function in people with traumatic brain injuries (TBI) without any serious side effects. Overall, fNIRS appears to be a safe and effective tool for examining brain activity.12345
Why are researchers excited about this trial?
Researchers are excited about using virtual reality (VR) walking with functional near-infrared spectroscopy (fNIRS) for traumatic brain injury (TBI) because it offers a unique, non-invasive way to study brain activity during movement. Unlike standard rehabilitation methods that might not provide real-time brain monitoring, this technique uses fNIRS to measure brain function while participants walk on a VR treadmill. This approach not only enhances the rehabilitation experience by providing engaging, interactive feedback but also allows scientists to gather valuable data on brain recovery in a real-world setting. The portable nature of the fNIRS device, which is lightweight and worn like a backpack, makes it easier to use in various clinical environments.
What evidence suggests that using fNIRS is effective for analyzing brain activity in individuals with chronic TBI during VR treadmill training?
Research has shown that functional near-infrared spectroscopy (fNIRS), a technology used in this trial, could aid in managing traumatic brain injury (TBI). Studies suggest that fNIRS detects changes in brain activity, even in patients with severe brain injuries who might not display obvious signs of awareness. This technology monitors brain oxygen levels and blood flow, crucial for assessing brain health after a TBI. Additionally, fNIRS can identify issues like bleeding inside the skull. Although more research is needed, these capabilities make fNIRS a promising tool for understanding and potentially improving brain function in TBI patients.23678

What Are the Treatments Tested in This Trial?
Interventions
- Functional Near-Infrared Spectroscopy (fNIRS)
Trial Overview
The study is testing the use of a portable brain-scanning device called fNIRS during treadmill exercises that may or may not include virtual reality (VR). The goal is to see if fNIRS can effectively measure brain activity in people with TBI under these conditions.

Experimental Treatment
This is a single-arm safety and feasibility study that will enroll up to 15 participants. Those meeting inclusion/exclusion criteria will be invited to enroll in the study. Following a thorough informed consent process, each participant will participate in one session of data acquisition. fNIRS data will be acquired with the NIRSport2, which is a fully-portable system as the device (weighs less than 2 pounds) is secured to the participant's back with backpack-like straps. Following signal optimization and signal quality checks, baseline fNIRS data will be obtained during 60-second periods of quiet, static standing. Then, each participant will complete up to 24 minutes of stepping on a treadmill with and without VR wearing the fNIRS cap. This training will be carried out in two 12-minute sessions with individuals being offered a sitting rest break in between. Training will be completed using the Motek C-Mill™ treadmill, which provides optional body weight support and VR feedback.
