What this study is about
This study is being conducted to determine the clinical safety and effectiveness of Pro-2-Cool mediated head and neck cooling when applied after concussion and improved symptomatology among adolescent athletes as quantified by post-concussion symptom severity (PCSS) score.
View original scientific description
This study is being conducted to determine the clinical safety and efficacy of Pro-2-Cool mediated head and neck cooling when applied after concussion and improved symptomatology among adolescent athletes as quantified by post-concussion symptom severity (PCSS) score.
Interventions
DEVICE
Pro2Cool Device
The Pro2Cool Device is a non-invasive hypothermic therapy ("cold therapy") device that provides localized cooling of the head and neck. Water and isopropyl alcohol cooled to 6°C by the chiller assembly circulate through the cooling garment to create conductive heat transfer from the scalp and carotid arteries, thus achieving cooling of the brain.
DEVICE
Sham Cooling Garment Device
The sham cooling garment device will be placed with impaired cooling function (only to the head), with sham treatment temperature being set to 19°C (instead of the therapeutic 6°C specification). There will be no thermal nylon barrier that will be used and flow to the neck bladder will be closed.
Primary outcome measures
Change quantified by post-concussion symptom severity (PCSS) assessment score
Time frame: Post-injury to 72-hour follow-up

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
