Dual Task Performance and Type II Diabetes Mellitus

August 4, 2025 updated by: Abdulkadir Ertürk, Kahramanmaras Sutcu Imam University

Investigation of Dual Task Performance of Individuals With Type 2 Diabetes Mellitus

The aim of this study is to compare the dual task performances of individuals with and without type 2 diabetes. Thus, it will be concluded whether having type 2 diabetes affects dual task performance.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In our daily lives, we often have to juggle many tasks simultaneously. Performing two tasks simultaneously is called dual-tasking. The ability to perform two tasks simultaneously is called dual-tasking performance. Dual-tasking performance can decrease in individuals with diabetes due to complications of diabetes. This study compared the dual-tasking performance of individuals with type 2 diabetes and healthy individuals using dual-tasking tests categorized as easy, medium, and difficult.

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Probability Sample

Study Population

Individuals who have had diabetes for at least 1 year and are over 50 years of age and their matched healthy controls constitute the study sample.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
type II diabetes mellitus group
Dual task tests were applied to the group with type 2 diabetes mellitus
Diagnostic test: one task
Single task tests consist of measuring walking times with normal walking (easy), walking with a 50% reduction in the base of support measured between the medial malleoli (medium difficulty) and tandem walking (difficult) tasks while applying the 10 meter walk test and time up go tests.
Diagnostic test: dual task
Dual task consists of single task plus tests of carrying glasses of water or counting backwards from a given number.
Healthy group
Dual task tests were administered to the healthy group
Diagnostic test: one task
Single task tests consist of measuring walking times with normal walking (easy), walking with a 50% reduction in the base of support measured between the medial malleoli (medium difficulty) and tandem walking (difficult) tasks while applying the 10 meter walk test and time up go tests.
Diagnostic test: dual task
Dual task consists of single task plus tests of carrying glasses of water or counting backwards from a given number.

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
10 meter walk test
Time Frame: one day

The dual task cost was calculated to measure dual task performance by applying the 10-meter walking test as single and dual tasks.

This cost will be calculated as follows:

(Dual task performance-single task performance)/ single task performance x100
one day
time up go test
Time Frame: one day
The dual task cost was calculated to measure dual task performance by applying the time up go test as single and dual tasks. This cost will be calculated as follows: (Dual task performance-single task performance)/ single task performance x100
one day

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
Stroop test
Time Frame: one day
There are 5 sections in this test. Section 1 includes reading black text, section 2 includes reading colored words related to color names, section 3 includes saying the color of shapes, section 4 includes saying the color of words that are not color names, and section 5 includes saying the color of colored words that are color names. Individuals are asked to read from left to right as fast as possible. The time taken is recorded in seconds.
one day
Dual task survey
Time Frame: one day
It is a test that questions the difficulties experienced by individuals during dual-task activities in daily life activities. The survey consists of 10 questions. The short duration of the survey is an advantage. The survey, which consists of 5 answers, is scored between 0 and 4. A score of ''4'' indicates that difficulties are experienced very often, ''0'' indicates that there is no difficulty.
