Mobile Dual-Task Brain and Balance Intervention for Concussion Recovery

14. maj 2026 opdateret af: Hyunhwa Lee

Boosting Brain and Balance: A Mobile Dual-Task Intervention for Athletes With Concussion and Mild Traumatic Brain Injury (mTBI)

This research study examines recovery after a sports-related concussion or mild head injury. Many athletes experience lingering problems with thinking, balance, and mood months after a concussion.

We are testing a new home-based program called BraW-Day™ (Brain & Walk Exercise Every Day). This 14-day program uses a mobile app on your smartphone and combines simple brain exercises (like counting backwards) with walking exercises. The idea is that doing these tasks together may help your brain and body recover more effectively.

What You'll Do:

  • Two in-person visits at UNLV (baseline and after 14 days) for assessments
  • Daily 15-minute exercises at home using the BraW-Day app
  • Provide a small saliva sample for biomarker testing
  • Complete brief questionnaires about your symptoms and health

Potential Benefits:

You may experience improvements in thinking, balance, or mood. Even if you don't benefit directly, your participation will help researchers understand how to better support athletes recovering from concussion.

Who Can Join:

  • Ages 18-40
  • Had a sports-related concussion or mild head injury within the past 3-12 months
  • Have a smartphone and can safely do light walking and simple tasks

This study is registered at ClinicalTrials.gov and approved by the UNLV Institutional Review Board to protect your safety and rights.

Detaljeret beskrivelse

Background and Rationale:

Mild traumatic brain injury (mTBI) and sports-related concussion affect thousands of athletes annually and often result in persistent cognitive, physical, and physiological symptoms that can extend months beyond the initial injury. Current recovery protocols typically focus on single-domain interventions (cognitive training alone or physical rehabilitation alone). Emerging evidence suggests that integrated, dual-task interventions-combining cognitive and physical exercise simultaneously-may enhance neuroplasticity and accelerate functional recovery by engaging multiple neural systems.

Study Rationale:

This feasibility study evaluates a novel mobile dual-task intervention (BraW-Day™) designed specifically for athletes recovering from mTBI/concussion. The intervention combines cognitive challenges with structured walking exercises, administered through a smartphone application for accessibility and adherence. We hypothesize that this integrated approach will improve cognitive function, physical balance, and physiological markers (heart rate variability) while demonstrating feasibility for home-based, technology-enabled delivery.

Intervention Description:

BraW-Day™ is a 14-day home-based mobile app intervention combining:

  • Walking exercises: Progressive heel-to-toe walking and figure-8 walking patterns
  • Cognitive tasks: Five-minute brain exercises (number counting, working memory tasks) performed concurrently with walking
  • Optional breathing exercises for relaxation and sleep support
  • Daily reminders and progression tracking via the Uplode mobile application

Each session is 15 minutes and performed daily for 14 consecutive days. The app provides real-time feedback and allows users to pause or adjust intensity as needed.

Study Design:

This is a single-arm feasibility study with pre-post assessment design. Participants complete two in-person study visits (baseline and post-intervention) separated by 14 days of home-based intervention.

Assessments:

  • Cognitive function: Neuro-QoL cognitive assessment
  • Lifetime trauma history: PhenX Lifetime Trauma and Victimization History Instrument
  • Physiological markers: Heart rate variability (HRV) measured via wearable sensors
  • Physical function: Eye-tracking (EyeLink) for oculomotor control; walking assessment using mobile sensors for movement analysis
  • Symptom severity: Ohio State University TBI Identification Interview, Rivermead Post-Concussion Symptoms Questionnaire, Neurobehavioral Symptom Inventory
  • Biological markers: Saliva collection for exosomal microRNA analysis to assess recovery at the molecular level
  • User experience: Semi-structured interview regarding intervention feasibility, acceptability, and perceived benefits

Primary Outcomes:

Feasibility metrics including recruitment rate, retention rate (completion of 14-day intervention), adherence to daily exercises, and safety.

Secondary Outcomes:

Changes in cognitive function, symptom severity, balance/gait, heart rate variability, and biomarker expression from baseline to post-intervention. User feedback on intervention acceptability and recommendations for future implementation.

Population:

Athletes aged 18-40 who sustained a sports-related concussion or mild TBI within 3-12 months prior to enrollment. Participants must be able to safely perform light physical activity and have consistent smartphone access.

Study Duration:

2 weeks of active intervention per participant; approximately 6.5-7 hours total time commitment.

Significance:

This study addresses a critical gap in mTBI recovery by evaluating an accessible, scalable intervention that integrates cognitive and physical rehabilitation. If feasible and effective, BraW-Day™ could provide athletes with an evidence-based home-based tool to optimize recovery and reduce persistent post-concussion symptoms.

Intervention / Behandling
Eksperimentel: 14-Day BraW-Day™ Intervention
Participants receive a 14-day home-based mobile dual-task intervention (BraW-Day™) delivered via the Uplode smartphone application. The intervention combines daily 15-minute sessions of heel-to-toe and figure-8 walking with concurrent cognitive tasks (e.g., counting backwards, working memory exercises). Cognitive task difficulty increases on Day 8. Optional guided breathing exercises are available via the app. Participants complete assessments at baseline (Day 0) and post-intervention (Day 15).
Adfærdsmæssigt: Home-Based Mobile Dual-Task Intervention (BraW-Day™)
Participants engage in a 14-day home-based mobile dual-task intervention using the Uplode smartphone application. Each daily session lasts 15 minutes and combines two concurrent components: (1) Walking exercises-progressive heel-to-toe walking alternating with figure-8 walking patterns; and (2) Cognitive tasks-five-minute brain exercises (e.g., counting backwards, working memory challenges) performed simultaneously with walking. On Day 8, cognitive task difficulty increases to provide progressive challenge. The app delivers daily reminders, tracks completion, and provides real-time feedback. Optional guided breathing exercises (5-10 minutes) are available for relaxation and sleep support. Participants self-pace the exercises and can pause the app if needed. The intervention is designed to engage multiple neural systems (motor and cognitive) simultaneously to enhance neuroplasticity and facilitate recovery from concussion/mild traumatic brain injury.
