Brain Injury & Stroke Recovery with Interactive Metronome®

Rewiring the Brain. Reclaiming Independence.

​

Every brain injury is different—but the goal is always the same: regain function, rebuild independence, and restore hope. Whether caused by stroke, concussion, or traumatic brain injury (TBI), damage to the brain disrupts the body’s ability to coordinate movement, process information, and regulate emotion.

Interactive Metronome® (IM) is an evidence-based therapy that helps the brain heal by restoring its internal timing system—an essential foundation for movement, cognition, speech, and emotional regulation.

​

 What Happens to the Brain After Stroke or TBI?

When an injury disrupts the neural pathways that control timing and coordination, it often leads to symptoms like:

• Difficulty walking or balancing

• Slurred or slowed speech

• Cognitive fatigue and memory loss

• Poor concentration and decision-making

• Delayed response time

• Anxiety, frustration, or emotional outbursts

• Difficulty with motor skills (e.g., dressing, feeding, driving)

This occurs because the brain’s timing network—involving the prefrontal cortex, cerebellum, basal ganglia, and sensorimotor areas—is no longer in sync. Without this rhythm, the brain cannot communicate efficiently across regions.

​

 How Interactive Metronome® Works

​

Interactive Metronome® (IM) is a computer-based neurotherapy that trains the brain’s internal timing system using rhythm and movement. Patients wear headphones and interact with hand or foot sensors, receiving auditory and visual feedback in milliseconds. This helps the brain recalibrate its timing and rebuild lost connections through neuroplasticity.

Over time, this process can lead to:

• Faster neural processing

• Improved motor planning and coordination

• Better memory and attention

• Smoother speech and language flow

• Increased emotional regulation

• ​

 What the Research Says

Numerous studies have shown that improving timing in the brain correlates with gains in:

• Executive functioning (attention, working memory, planning)

• Speech and language processing

• Mobility and gait symmetry

• Sensory integration and balance

• Emotional self-regulation

• ​

 Clinical Studies:

• Neurorehabilitation (2009): Patients with stroke who completed IM training showed significant improvements in gait velocity, stride length, and balance.

• Brain Injury Journal (2013): IM was linked to measurable improvements in processing speed and working memory for patients post-concussion and mild TBI.

• American Journal of Occupational Therapy (2001): Reported improved timing and functional performance in patients following IM therapy.

“IM engages key areas of the brain involved in timing, movement, cognition, and emotion—helping patients rewire and recover from the inside out.”
— Dr. Kevin McGrew, Educational Neuroscience Researcher

 Who Can Benefit?

IM is appropriate for individuals recovering from:

• Ischemic or hemorrhagic stroke

• Traumatic brain injury (TBI)

• Post-concussion syndrome

• Aneurysm recovery

• Brain tumor surgery

• Cognitive and motor decline due to aging

• ​

 What Does IM Training Look Like?

​

Sessions are tailored to each patient’s ability and recovery stage:

Early Phase (Acute/Low Mobility)Later Phase (Functional Integration)

- Seated tapping & hand exercises- Standing, stepping, and balance drills

- Passive limb movement with cueing- Dual-task memory + movement exercises

- Breath and posture synchronization- Simulated ADLs (dressing, walking, driving)

Sessions use precise movement tracking and feedback in milliseconds, helping the brain learn how to correct errors and restore timing.

​

 Real-World Outcomes

​

✔️ Regain walking stability and confidence
✔️ Improve speech speed and clarity
✔️ Reduce cognitive fatigue
✔️ Enhance short-term memory and recall
✔️ Increase attention span
✔️ Lower anxiety and emotional overload
✔️ Boost independence in daily living tasks

​

 Why Timing Matters in Recovery

The brain is like a symphony—it only works well when every section plays in time. IM helps restore that internal beat, allowing areas of the brain to communicate more clearly and efficiently.
