The Effect of Attention on Postural Control

Completed

• Conditions: ADHD - Attention Deficit Disorder with Hyperactivity; Postural Instability

• Registration Number: NCT06711406
• Lead Sponsor: Yeditepe University

Brief Summary

Objective: This study investigates the relationship between postural control and sustained attention in individuals with probable ADHD. Motor control issues, including balance deficits, are observed in 30-50% of children with ADHD. These deficits may extend into adulthood, yet research on postural control in adults with ADHD is limited. This study aims to address this gap by exploring the connection between attention and postural stability in adults with ADHD.

Background: ADHD is a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity, affecting both children and adults. Studies have shown that postural control relies on coordinated functioning of sensory and neuromotor systems, which ADHD may impact. In children, postural challenges are more pronounced in conditions requiring complex sensory integration. However, research on adults with ADHD is sparse, though preliminary findings suggest postural instability and possible links to cerebellar differences.

Methodology: The study evaluates sustained attention and postural control in adults with ADHD, using the Adult ADHD Screening Scale (ASRS-5) and postural stability assessments under dual-task conditions. By examining attention-driven postural responses, the study contributes to developing therapeutic balance protocols for individuals with ADHD.

Hypotheses:

H0: No relationship exists between postural control and sustained attention in individuals with ADHD.

H1: A relationship exists between postural control and sustained attention in individuals with ADHD.

Significance: This study contributes to a better understanding of the neurophysiological links

Primary Outcome Measures

Name	Time	Method
Postural Control: Prokin PK 252.	30 minutes	The Prokin device (Prokin PK 252) is a proprioceptive system for static and dynamic balance assessment and training. The device shows multiple programs for balance assessment and treatment. For this experiment, the "Static Stability Assessment Program" will be chosen to provide detailed and precise data of each participant while static standing through the stabilometry platform and the sensor placed on the trunk. Stabilometry allows participants to be evaluated by detecting the oscillation of the Centre of Pressure (CoP) during static standing. The platform of the Prokin device will calculate the CoP sways of the participants and the postural control data will be transferred to the computer screen. The assessment will be done in two conditions: a two-foot standing position without stimulus (eyes open, eyes closed), and a two-foot standing position with dual-task (eyes open, eyes closed). The dual-task procedure involves instructing participants to count down from 100 by 3.

Secondary Outcome Measures

Name	Time	Method
Cognitive tests: Sustained Attention to Response Task (SART):	5 minutes	The Sustained Attention to Response Task (SART) is a computer-based task where participants need to refrain from responding to a rare target (the digit 3) embedded within a series of more frequent non-targets (0-2, 4-9). Participants were instructed to prioritize both accuracy and speed in completing the task.
