Dual Task Performance and Type II Diabetes Mellitus

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: Completed
• Conditions: Type II Diabetes Mellitus; Dual Task Cost
• Intervention / Treatment: Diagnostic test: one task; Diagnostic test: dual task

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.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
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

Outcome Measure	Measure Description	Time Frame
10 meter walk test	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	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

Outcome Measure	Measure Description	Time Frame
Stroop test	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	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.	one day
