Brock String Therapy for Concussion
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if Brock String therapy can enhance and accelerate recovery from concussions. Brock String therapy, a simple eye exercise, might improve focus and reduce recovery time for athletes who recently experienced a concussion. Participants will either perform these eye exercises at home twice daily or receive the usual care without the exercises. The trial seeks athletes who sustained a concussion during a sport in the last two days and have difficulty focusing their eyes on nearby objects. As an unphased trial, this study provides a unique opportunity to explore a potentially effective new therapy for concussion recovery.
Do I need to stop 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 Brock String Therapy is safe for concussion recovery?
In a previous study, researchers found Brock String Therapy safe for people recovering from a concussion. The study included participants aged 11 to 30, all within 10 days of their concussion. It revealed no major safety issues or negative effects from the therapy. Most participants experienced positive results, with about 77% reporting significant improvements in their symptoms. This suggests Brock String Therapy is a safe option for aiding recovery after a concussion.12345
Why are researchers excited about this trial?
Unlike the standard of care for concussions, which often involves rest and gradual return to activities, Brock String Therapy offers a hands-on approach aimed at improving visual coordination and balance. This therapy uses a simple tool—a string with colored beads—to help retrain the brain's ability to coordinate vision, which can be disrupted after a concussion. Researchers are excited about this technique because it can be done at home, is non-invasive, and may accelerate recovery by directly addressing visual disturbances that are sometimes overlooked in traditional concussion management.
What evidence suggests that Brock String Therapy is effective for concussion recovery?
Research shows that Brock String Therapy, which participants in this trial may receive, can help with problems focusing on nearby objects, often occurring after a concussion. Studies have found that this therapy improves the ability to focus on close objects better than usual treatments. Specifically, those who used the Brock String could see things up close more easily. Additionally, data from the researchers suggests that over 90% of patients experienced significant improvement in their symptoms. Brock String Therapy is a simple and low-cost method that might help people recover from concussions more quickly.13467

Are You a Good Fit for This Trial?
This trial is for athletes aged 12-20 who have had a concussion during organized sports in the last 48 hours and show a receded near point of convergence (NPC) greater than 10 centimeters. It's not suitable for those without smartphone access, with severe symptoms, recent concussions, vestibular or seizure disorders, significant brain injury history, intellectual disabilities, or substance abuse issues.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Brock String Therapy
Trial Overview
The study tests if Brock String therapy helps improve NPC measurements and cognitive test scores post-concussion better than standard care. It also looks at whether this therapy can shorten the time it takes for injured athletes to return to play.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Active Control
Participants will receive instruction on Brock String therapy after first clinic visit (\<48 hours post) injury, and will complete home therapy exercise twice daily
Participants will receive standard of care (i.e., no Brock String therapy within the first week post injury) but will be informed they will receive any therapy deemed necessary at follow up visit 7-10 days post injury, consistent with standard of care
