Effect of cognitive task on postural control of the patients with chronic ankle instability during single and double leg standing

Test-retest reliability of linear and nonlinear measures of postural stability during visual deprivation in healthy subjects

“…If one or more of these systems fail, or the sensory information is not correctly processed, the risk of a fall or instability increases. As balance is the foundation for all voluntary motor skills, considerable research has been conducted to evaluate the balance performance in patients with low back pain 3 , 4 , 5 , 6 ) , anterior cruciate ligament injury 7 , 8 ) , and chronic ankle instability 9 , 10 ) . Many variables have been developed from force platform signals to quantify postural steadiness.…”

Comparison of effect of wobble board training with and without cognitive intervention on balance, ankle proprioception and jump landing kinetic parameters of men with chronic ankle instability: a randomized control trial

“…These results are consistent with the theory of limited capacity of attention, which states that when dual tasks are performed simultaneously, if the total attention capacity of the individual is less than the attention required to perform both tasks, the result will be a malfunction of both tasks or one of them, and a decrease in balance while performing a dual task can be a function of this interference theory. In contrast, Shiravi et al (2016) state that dual cognitive task combined with a motor task leads to a reduction in postural fluctuations [25], which is in line with the results of Andersson et al (2002) [48]. This discrepancy between research results can be due to differences in inclusion criteria of the subjects, including their age or health status, or because of the type of cognitive task selected in terms of severity or ease.…”

“…Also, Rahnama et al (2010) reported that postural fluctuations in people with ankle instability in both anteroposterior and posteromedial directions in single-leg standing together with CI are higher than single-legged standing without CI [46]. While Shiravi et al (2016) in a study investigated the effect of dual task on postural fluctuations while standing on one leg in people with CAI and showed that postural fluctuations were decreased in both anteroposterior and posteromedial directions in dual task mode [25].…”

“…It is a common method to study posture fluctuations by calculating the mean displacement of the leg pressure center. Various studies have presented balance exercises, especially WBT, for post lateral ankle sprain rehabilitation and have also been shown to exert positive effects on reducing posture fluctuations [25,34,[40][41][42].…”

“…Due to the fact that the subjects are on the Wobble board, if they use verbal or motor interventions, it may upset the balance. Therefore, this CI has been used to prevent any movement disorder in the body [25].…”
