Upon suffering a concussion, a neurometabolic cascade including an increase in glucose and oxygen demand occurs for up to 48 hours post-insult.5 This period of increased glucose and oxygen demand is coupled with a period of hyperperfusion and decreased cerebral blood flow. 6-9 Cryotherapy in the musculoskeletal system has been shown to decrease tissue temperature, blood flow, oxygen and metabolic demands.10-17 Cryotherapy following moderate or severe traumatic brain injury has been demonstrated to decrease intracranial metabolic processes and oxygenation consumption.18-23 Although the benefits of cryotherapy have been established in moderate-severe TBI, the effects of superficial cranial cooling in individuals with and without concussion are unknown. The purpose of this randomized control trial is to evaluate the effects of superficial cryotherapy on cerebral blood flow and cognitive function in healthy, recreationally active young adults.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Oxygenated blood | Oxygenated blood based on functional near-infrared spectroscopy (fNIRS) data output | Oxygenated blood was collected throughout the data collection period (45 minutes) | |
Primary | Deoxygenated blood | Deoxygenated blood based on functional near-infrared spectroscopy (fNIRS) | Dexoygenated blood was collected throughout the data collection period (45 minutes) | |
Primary | Stroop Task reaction time | Reaction time measured in milliseconds while completing the Stroop Task | Stroop Task reaction time was collected prior to and following the intervention. Each test took approximately 5 minutes to complete. |
