Sound Therapy for
Brain Injury Recovery

What this session is about

The brain has a rhythm system. TBI often disrupts it — you might notice this as difficulty walking at an even pace, problems with timing and sequencing, or a general sense of being "off." Rhythmic auditory stimulation (RAS) uses external rhythm to help the brain re-synchronize these systems.

Research shows RAS can improve stride length and walking speed in TBI patients, and that these improvements can persist. You don't need to be walking to benefit — any rhythmic movement (tapping, swaying, even just listening attentively) engages the same pathways.

What you'll need

Step by step

1. Pre-session check-in in your Journal. Note anything that's changed since Session 1.
2. Open the Binaural Beat Processor. This time, select the Beta (13–30 Hz) preset — more activating than Alpha. You want to feel alert but comfortable.
3. Listen for 5 minutes. Then, while the audio continues, begin to gently tap your fingers, hands, or feet in time with a beat you hear in the sound. Don't force it — find a rhythm that feels natural.
4. If you're comfortable doing so, try walking slowly while listening. Let the rhythm guide your footsteps. If walking isn't accessible to you right now, rocking or swaying works just as well. The goal is motor synchronization, not exercise.
5. Do this for 15–20 minutes total.
6. Sit quietly for 3–4 minutes after stopping. Notice the contrast.
7. Post-session log. How did movement feel during the session versus without it?

Reflect on this

• Did your movement feel more coordinated with the rhythm, or did it feel effortful to match it?
• Was there a tempo that felt "right" — not too fast, not too slow?
• Did your thinking feel different when your body was moving to a rhythm?

What this session is about

TBI is exhausting. The brain is working harder than usual to do things that used to be automatic. Sleep is often disrupted, anxiety is common, and emotional regulation can feel impossible. This session targets that.

Delta and Theta frequencies (0.5–7 Hz) are associated with deep rest, sleep, and emotional processing. Binaural beats in these ranges don't put you to sleep — they create conditions that make rest easier. Think of it as giving your brain permission to slow down.

What you'll need

Step by step

1. Do this session in the evening, at least 30 minutes before bed, or during a rest period during the day.
2. Pre-session check-in. Note your anxiety level and fatigue level specifically.
3. Lie down or sit in a reclined position. Headphones on. Open the Binaural Beat Processor and select Theta (4–8 Hz). If Theta feels too deep, try low Alpha (8 Hz) first.
4. Close your eyes. Let your thoughts move. Don't try to stop them. The goal isn't emptying your mind — it's changing the state your brain is operating in.
5. Listen for 25–35 minutes. If you fall asleep, that's fine. That's the point.
6. If doing this as a pre-sleep session, go to bed after completing it. Open the Journal in the morning and log your sleep quality — how long, how deep, how you feel on waking.

Reflect on this

• Did your anxiety feel different after 20 minutes than when you started?
• If you tracked your sleep — was there any difference?
• What does rest feel like in your body right now, compared to before this program started?

What this session is about

This session isn't about learning something new. It's about taking everything you've observed across the first three sessions and making it yours. What worked? What didn't? What do you want to do again? What would you change?

Recovery isn't a four-week program. It's a practice. This session is about building the version of that practice that actually fits your life.

What you'll need

Step by step

1. Open your Music Composition Journal and read back through all three previous session logs. Don't analyze — just read. Let patterns emerge.
2. Answer these three questions in your journal: What frequency or state helped you most? What time of day felt best for sessions? What would make this easier to do regularly?
3. Design your personal Sound Practice: choose one frequency preset that works for you, a duration that's sustainable (even 10 minutes counts), and a time of day that fits your life. Write it down.
4. Do a final 20-minute session using your chosen preset. Use the Audio Mandala Generator after — create a visual record of this session's sound as a marker of where you are now.
5. Complete your final journal entry. Compare your energy, anxiety, and sleep quality to Session 1. Note any changes, however small.

Where to go from here

The program ends here, but the practice doesn't have to. The tools are always free. Your journal data belongs to you. The frequencies that helped you in these sessions will continue to help you if you use them.

If you've found this useful and you're working with a rehabilitation team, share your journal logs with them. The data you've collected — mood, sleep, energy, observations across four sessions — is clinically relevant and worth discussing.

If you'd like to connect with Ptim directly about your experience, or if you're a clinician who wants to implement this program formally, the contact form on the main site is the place to start.

Reflect on this

• How are you different now than when you started Session 1?
• What do you want your relationship with sound to look like going forward?
• Is there something you'd tell someone else who was just starting this program?
