![]() ![]() When subjects were subjected to dual task trials, we were able to sequentially observe the demands of attention factors, how they differed depending on the combinations of tasks that were presented, and the effects of attentional factors on the balance control. We examine the sequential relationships of dual task on the postural control. Furthermore, the sequential relationship between automatic control and attention factors during in dual task contexts is still unclear. However, the relationships between these parameters and postural sway have not been investigated in a dual task study design. Several studies have explored the effects of tendon vibration on the postural control and the ability to complete tasks. Verbal and nonverbal working memories are thought to be associated with different regions of the brain. Verbal tasks are considered relatively easy for participants to complete, while nonverbal tasks are more difficult due to their attention demanding characteristics. Both verbal and nonverbal tasks have been applied as secondary tasks in dual task paradigms. The secondary task in dual task paradigms is usually attention demanding, and task intensity and difficulty influence postural control in various ways. However, in several studies directional shifts were either increased or decreased according to the stimulation intensity and type. In previous studies, tendon vibration stimulation was shown to increase the postural sway, and subjects frequently experience vibration-induced compensatory losses of balance, falling in the same direction as the applied vibration. When vibrations are applied during primary postural tasks, they typically cause directional shifts in subjects, due to increasing primary afferents that are discharged during vibration and interpreted as lengthening of the vibrated muscles. showed that adults of all ages exhibit delays in reaction time as postural task complexity increases. The primary task is usually postural control, which involves standing on a force plate with different levels of difficulty for example, on an uneven surface or standing on one leg. ĭual task paradigms are important tools for understanding the balance control. ![]() The attentional factors are thought to arise from the central nervous system, while the automatic factors are reflex-controlled by somatosensory (muscle, skin, and pressure receptors) visual and vestibular inputs. Postural control can be influenced by the automatic (reflex-controlled) and attentional (high cortical) factors, and previous studies have suggested that the postural control systems require varying degrees of attention, depending on the postural tasks involved and the age of the subjects. Do not miss visiting this park when you are in Springfield.Sensory perturbations of visual, somatosensory, and vestibular systems disrupt the postural stability. There is a display board explaining how they work. On the lake waters are demonstration projects for ‘Floating Wetlands’. There is a beautiful trail around the lake (about half a mile). The lake is the main feature of the park the lake gets its waters from the springs hidden in the caves in the park. The park is quite beautiful with several attractive features, though it is relatively compact. There is a historical marker in the park indicating that Sequiota at one time used to be a State Park, and now it is managed by the city of Springfield. The park also serves as a major trailhead for the Galloway Creek Greenway trail the park is approximately in the middle of the north-south running 5-mile trail. Many people were at the park proving that it is a popular park in Springfield. I found this park by chance while riding bike along the Galloway Creek Greenway (bike trail). Sequiota Park is a wonderful nature oasis in the urban area of Springfield. ![]()
