Summary of "Comparing the effects of external focus of attention and continuous cognitive task on postural control in anterior cruciate ligament reconstructed athletes."

External focus (EF) of attention and continuous cognitive task (CCT) reduced postural sway in young and adult people owing to the automatic process of postural control, but their effects on postural control in athletes with musculoskeletal injury like anterior cruciate ligament (ACL) reconstruction are unclear. The present study aimed to reveal the effects of EF of attention and CCT on postural control in ACL reconstructed (ACL-R) athletes by comparing the pattern of the condition-group interaction between ACL-R and healthy athletes. The participants included healthy athletes (n = 20) and ACL-R athletes (n = 20). Postural control was examined during an operated leg stance on a wobble board positioned on a force plate. Three conditions were performed: single postural task (control condition), postural task with EF of attention (focusing on a planar leveling app in a smartphone placed on the wobble board) and postural task concurrent with CCT (three-digit sequence task). Measurement parameters, including sway area, amplitude, velocity, and mean power frequency (MPF), were the traditional center of pressure (COP) variables. A significant difference was found between ACL-R athletes and healthy subjects for the AP amplitude in the control condition as well as the ML amplitude in the CCT condition. Furthermore, in the ACL-R group, cognitive demand significantly decreased postural sway, while postural sway was not different between the conditions for the healthy group. Results also indicated that CCT significantly decreased sway velocity and increased mean power frequency in both groups, while EF of attention did not change any COP measures. Concurrent CCT decreases postural sway in ACL-R athletes, while it does not have significant effects on healthy subjects. EF of attention did not affect postural control in both study groups.

A cardiac arrhythmia that is caused by interaction of two independently initiated cardiac impulses of different rates from two separate foci. Generally one focus is the SINOATRIAL NODE, the normal pacemaker. The ectopic focus is usually in the HEART VENTRICLE but can be in the HEART ATRIUM or the ATRIOVENTRICULAR NODE. Modulation of the parasystolic rhythm by the sinus rhythm depends on the completeness of entrance block surrounding the parasystolic focus.

A neuropsychological test designed to assess different memory functions. It may incorporate an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess memory related cognitive function.

Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes.

A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.
