This review presents a conceptual framework and supporting evidence that links impaired motor control after sport-related concussion (SRC) to increased risk for musculoskeletal injury. Multiple studies have found that athletes who are post-SRC have higher risk for musculoskeletal injury compared to their counterparts. A small body of research suggests that impairments in motor control are associated with musculoskeletal injury risk. Motor control involves the perception and processing of sensory information and subsequent coordination of motor output within the central nervous system to perform a motor task. Motor control is inclusive of motor planning and motor learning. If sensory information is not accurately perceived or there is interference with sensory information processing and cognition, motor function will be altered, and an athlete may become vulnerable to injury during sport participation. Athletes with SRC show neuroanatomic and neurophysiological changes relevant to motor control even after meeting return to sport criteria, including a normal neurological examination, resolution of symptoms, and return to baseline function on traditional concussion testing. In conjunction, altered motor function is demonstrated after SRC in muscle activation and force production, movement patterns, balance/postural stability, and motor task performance, especially performance of a motor task paired with a cognitive task (i.e., dual-task condition). The clinical implications of this conceptual framework include a need to intentionally address motor control impairments after SRC to mitigate musculoskeletal injury risk and to monitor motor control as the athlete progresses through the return to sport continuum.  相似文献   

Emerging from the Pipeline: African American Students,Socioeconomic Status,and College Experiences and Outcomes   总被引：1，自引：0，他引：1

This study focuses on how social class affects the college experiences and outcomes for African American students in 4-year colleges and universities. Using a national, longitudinal data base, the findings indicate that low SES African American students have less contact with faculty, study less, are less involved with student organizations, work more, and have lower grades than do their high SES peers or all African American students. Furthermore, 9 years after entering college, low SES students report lower incomes, lower rates of degree attainment and lower aspirations than their high SES peers, and were less likely to have attended graduate school. Logistic regression results indicate that sex, college GPA, and plans following college significantly affect the likelihood that a student will attend graduate school.
