King-Devick Test Score Is Linked To Cerebral Vasoreactivity During Acute Recovery Phase Post-Concussion, Madison E. Mccredie, Abigail Reichow, Mathew Stokes, Kathleen R. Bell, Sushmita Purkayastha
International Journal of Exercise Science: Conference Proceedings
The King-Devick (KD) test is a quick screening tool used to detect oculomotor and attention related brain function impairments following a concussion. Adequate cerebral blood flow (CBF) is an indicator of structural and functional integrity and impairments in CBF have been linked to cognitive deficits following concussion. Cerebral vasoreactivity (CVR), a key measure of hemodynamic reserve, is an important factor in CBFregulation. PURPOSE: To examine the association between CVR and oculomotor and attention function, using KD test scores, in collegiate athletes following a concussion. METHOD: Eighteen male and female athletes diagnosed with a sports-related concussion were enrolled in the prospective …
Impairments In Cerebral Autoregulation Is Associated With Postural Control In Sports Related Concussion, Abigail L. Reichow, Madison Mccredie, Mathew Stokes, Kathleen R. Bell, Sushmita Purkayastha
Impairments In Cerebral Autoregulation Is Associated With Postural Control In Sports Related Concussion, Abigail L. Reichow, Madison Mccredie, Mathew Stokes, Kathleen R. Bell, Sushmita Purkayastha
International Journal of Exercise Science: Conference Proceedings
Global and regional deficits in cerebral blood flow are reported with concussions, a major public health concern, with approximately 3.8 million incidences occurring annually in the United States alone. Recent studies have identified an increased risk of musculoskeletal injuries in athletes upon return-to-play. Complexity index is a sensitive marker of postural control, with low complexity index indicating a poor physiological adaptation to stress. PURPOSE: Twofold; 1. Examine complexity index and dynamic cerebral autoregulation (dCA) at rest and during physical stress (rhythmic squatting) in collegiate athletes following a concussion in comparison to non-injured controls. 2. Examine the association between complexity …
