NCT06929923

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change quantified by post-concussion symptom severity (PCSS) assessment score

    Post-injury to 72-hour follow-up

Secondary Outcomes (1)

  • Number of adverse events associated with the head-and-neck cooling treatment

    Treatment to 72-hour follow-up

Study Arms (2)

Pro2Cool intervention with standard of care

EXPERIMENTAL

The treatment arm will receive standard of care for concussion along with 30 minutes of headneck cooling in the clinic while being monitored for side effects. The Pro2Cool® will be used to provide head and neck cooling.

Device: Pro2Cool Device

Sham Pro2Cool with standard of care

SHAM COMPARATOR

The control arm will receive standard of care like the treatment group, along with 30 minutes of sham Pro2Cool® placement in the clinic while being monitored for side effects. The Pro2Cool® device will not be used to provide neck cooling; a 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).

Device: Sham Cooling Garment Device

Interventions

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.

Pro2Cool intervention with standard of care

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.

  • Slurred speech which has not resolved within 72 hours of concussive 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
  • +5 more criteria
