What is the purpose of this trial?

This trial aims to determine if different types of physical therapy can improve mobility, balance, and cognitive skills in individuals who have experienced a traumatic brain injury (TBI). It compares three approaches: regular walking and balance exercises, High Intensity Step Training (HIST), and intense step training combined with virtual reality. Suitable candidates have had a TBI within the last 6 months, completed initial rehabilitation, and can walk ten feet with some assistance. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, providing participants an opportunity to contribute to significant findings.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Previous studies have shown that high-intensity step training benefits people recovering from brain injuries. Participants in these studies improved their balance and walking distance, indicating the training is well-tolerated. Safety measures ensured participants remained safe during exercises.

Adding virtual reality to this high-intensity training also appears promising. Research shows that people with brain injuries responded well to virtual reality, finding it engaging and easy to use, which bodes well for safety and comfort.

Overall, both high-intensity step training and its virtual reality version seem safe for people with brain injuries, based on past research. Participants generally handle these treatments well, and no major safety issues have been reported. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about this trial because it explores innovative approaches to improve recovery for traumatic brain injury (TBI) patients. High Intensity Step Training (HIST) stands out by emphasizing high cardiovascular intensity and more steps per session, potentially enhancing physical endurance and neuromuscular coordination more effectively than traditional methods. Furthermore, the combination of HIST with Virtual Reality (HISTVR) is particularly intriguing, as it aims to stimulate brain activity and muscle engagement simultaneously, which could lead to more significant improvements in motor function and cognitive recovery. These approaches offer a fresh perspective compared to conventional gait and balance training, which typically focuses on steady progression through varied conditions and strength exercises.

What evidence suggests that this trial's treatments could be effective for improving mobility and balance after traumatic brain injury?

This trial will compare different physical therapy approaches for traumatic brain injury recovery. Research has shown that High Intensity Step Training (HIST), one of the treatments participants may receive, can greatly improve walking balance and movement in people recovering from traumatic brain injuries (TBI). Studies have found that patients doing HIST experience greater improvements in fitness and thinking skills compared to traditional therapies. Another treatment option in this trial is High Intensity Step Training with Virtual Reality (HISTVR). Research suggests that using VR makes the therapy more engaging and may further enhance thinking skills. Combining high-intensity training with VR aims to increase brain activity and better activate muscles, potentially leading to improved outcomes. Overall, both methods appear promising in aiding recovery by enhancing movement, balance, and thinking skills. ^{1 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• High Intensity Step Training

Trial Overview The study tests three methods to improve mobility after TBI: standard gait and balance training; high intensity step training (HIST); and HIST combined with virtual reality. It aims to see if these treatments also enhance cognitive functions alongside physical abilities like balance.

How Is the Trial Designed?

Group I: High Intensity Step Training with Virtual Reality (HISTVR) Experimental Treatment 1 Intervention

The third arm combines virtual reality with HIST, designed to increase cortical excitability while concurrently activating the neuromuscular system.

Group II: High Intensity Step Training (HIST) Experimental Treatment 1 Intervention

High Intensity Step Training (HIST) focuses on the repetition of stepping at higher cardiovascular intensities and yielding a greater number of steps per training session.

Group III: Conventional Gait and Balance Training (CGBT) Active Control 1 Intervention

The current approach for walking retraining, Conventional Gait and Balance Training (CGBT) focuses on walking training in a variety of conditions, obstacle management training, functional independence training, strength training, and standing dynamic balance training.

A 3-month community-based aerobic exercise training program showed a trend toward improved cardiorespiratory fitness (CRF) in individuals with traumatic brain injury (TBI), with an 8% increase in VO2peak compared to a 4% decrease in a stretching and toning group, indicating potential efficacy of aerobic exercise for this population.

The study demonstrated that while it is feasible to conduct exercise training in community settings for TBI patients, only 50% of participants adhered to the program, highlighting the need for strategies to improve adherence in future trials.

In a small clinical trial with 12 adults with traumatic brain injury (TBI), an 8-week program of rapid-resisted elliptical training significantly improved dynamic balance and motor processing speed, as measured by the High-Level Mobility Assessment Tool (HiMAT) and dual-task performance.

The training not only enhanced physical abilities but also positively impacted sleep quality, which correlated with reductions in depression and improvements in learning, highlighting the interconnectedness of physical and cognitive recovery in TBI patients.

High-level mobility (HLM) training appears to be generally safe in the early sub-acute phase following moderate-to-extremely severe traumatic brain injury (TBI), but the lack of comprehensive reporting on adverse events and symptoms makes it difficult to establish a clear safe timeframe for its initiation.

Only six adverse events were reported across 19 studies, with one instance of a concussion-like symptom, indicating that while HLM may not provoke significant issues, more thorough monitoring and research are needed to ensure patient safety during recovery.
