Effect of Chronotype on Balance and Cognitive Function

September 11, 2026 updated by: Yasin Yildirim, Istanbul Gedik University

Examining the Relationship Between Balance and Cognitive Functions Based on Chronotype

Balance is the ability of an individual to maintain posture against gravity and sustain stability during movement; it depends on the coordinated functioning of the proprioceptive, visual, and vestibular systems, as well as the central nervous system. Current studies show that movement control occurs not only through the motor system but also through the interaction of sensory-cognitive-motor components. Cognitive functions encompass processes such as attention, memory, visuospatial skills, and executive functions, with attention and visuospatial processing playing a particularly important role in balance control. The literature reports significant relationships between balance and cognitive functions, particularly noting that increased attention requirements in dual-tasking situations negatively impact balance performance. Furthermore, it has been shown that both balance performance and cognitive functions are affected by circadian rhythm and chronotype, with individuals exhibiting different performance levels at different times of the day. Despite this, studies examining the relationship between balance and cognitive functions appear to have insufficiently addressed the chronotype factor. Therefore, the aim of this study is to investigate how the relationship between balance and cognitive functions changes according to individuals' chronotypes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Chronotype
Time Frame: baseline - 2 weeks later
It will be assessed by survey (Horne Ostberg). The survey contains a total of 19 questions. Points will be added up based on participants' answers to obtain a score between 16 and 86. 16-30 will be considered evening type, and 70-86 will be considered morning type.
baseline - 2 weeks later

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
balance
Time Frame: baseline - 2 weeks later
It will be assessed with KoreBalance balance system. Users will be asked to keep their eyes open while maintaining a center of gravity on an electronic device. Results are presented as point scores.
baseline - 2 weeks later
Attention measurement
Time Frame: baseline - 2 weeks later
It will be assessed with stroop test. Individuals will be tested at a desk. They will first be asked to read only the text written in three different colors. Then they will be asked to read the colors of the text. The total score will be recorded in milliseconds.
baseline - 2 weeks later
Visuo-spatial attention
Time Frame: baseline - 2 weeks later
It will be assessed with Flanker task. Eriksen Flanker Task is a classic cognitive psychology test that measures selective attention and response inhibition. You are asked to identify the direction of a central target (e.g., an arrow) while ignoring distracting "flanker" arrows on either side, which can either point the same way (congruent) or opposite (incongruent). The total correct responses are kept.
baseline - 2 weeks later

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
