Evaluating the Effects of Cognitive Load on Postural Stability and Balance Recovery Mechanisms in Younger Adults

What this Trial Is About

This research aims to understand how cognitive load affects balance and the body's ability to recover from sudden disturbances in young adults aged 18 to 30. The study looks at how doing mental tasks while trying to maintain balance impacts postural stability and the ability to prevent falls. It also compares these effects between male and female participants to fill gaps in knowledge about the connection between thinking processes and physical balance. Participants will undergo several assessments involving standing on force plates to measure static balance and balance recovery after being physically disturbed. They will perform tasks involving cognitive load, such as backward counting with subtraction and a color-naming test, during these assessments. The study uses devices to monitor heart rate variability and skin response to understand the cognitive load's impact on balance mechanisms. Different experimental conditions include balance testing alone, balance with cognitive tasks, and perturbation with or without cognitive tasks. Throughout the study, participants will be evaluated using various measures, including center of pressure, postural sway, balance recovery, heart rate variability, galvanic skin response, and a NASA Task Load Index to assess mental workload. These measurements occur at baseline and during interventions to see how cognitive tasks affect balance control. The study involves randomized group assignments and triple masking to ensure unbiased results. The total study duration and follow-up details are based on these assessments during the experimental sessions.
