Official title
A Double-Blind, Randomized Study of Clinical Efficacy of Hypothermic Therapy Following Concussion in Adolescent Athletes as Compared to a Sham-Controlled Population
Overview
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.
Detailed description
This is a multi-center, prospective, randomized, double-blinded, dual-arm comparative study enrolling up to a total of 66 patients (approximately 33 patients in the treatment arm and 33 patients in the control arm) following sports-related, concussion.
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]
Secondary outcome measures (1)
- Number of adverse events associated with the head-and-neck cooling treatment [Time frame: Treatment to 72-hour follow-up]
Eligibility criteria
Inclusion criteria
- Males and females, 13-21 years of age
- Confirmed concussion diagnosis consistent with American Congress Rehabilitation Medicine guidelines 21, without any of the following:

- Loss of consciousness greater than 30 minutes
- Post-traumatic amnesia lasting over 24 hours
- Glasgow Coma Scale (GCS) ≥ 13 at the time of initial injury for study enrollment.
- Post-Concussion Symptom Scale Score minimum of 15
- Initial provider visit is within 7 days of injury

- Physical (e.g., head or neck injury that requires medical treatment) or mental disability hindering adequate response to assessment of symptoms
- Hemodynamic instability/medical condition requiring further acute life-saving medical intervention
- History of psychiatric disorder that includes suicide attempts within the last 6 months, unmanaged depression or anxiety, hospitalization for psychiatric treatment within the last 6 months
- Known brain mass, intracranial hemorrhage, skull fracture
- Scalp abnormalities including laceration or bleeding
- Presence of ventriculoperitoneal (VP) shunt
