Impact of Dual vs. Single Task Exercise on Cognitive Function, Balance, and Functionality in Type 2 Diabetes

Официальное название

Effects of Dual Task and Single Task Exercise Training on Cognitive Performance, Balance and Functionality in Patients With Type 2 Diabetes

Обзор

Diabetes Mellitus is defined as a carbohydrate mechanism disorder in which glucose cannot be used as an adequate energy source and is produced excessively, causing hyperglycemia. For the diagnosis of diabetes, an increase in HbA1c in the blood or a high glucose concentration in venous plasma is examined. Although there are various clinical subtypes, Type 2 diabetes constitutes 90% of the approximately 537 million diabetics worldwide. In the treatment of diabetes, there are pharmacological treatments and lifestyle changes to ensure glycemic control. The most important lifestyle change interventions are balanced calorie intake, increased physical activity and regular exercise. The effect of exercise on complications associated with Type 2 diabetes, such as improving glycemic control, reducing inflammation and reducing cardiovascular risk, is clear and it is known that these also affect cognition. In this context, dual-task exercises that can target both the improvement of parameters related to postural control and balance as a physical development and the development of cognitive functions are gaining importance. The aim of dual-task exercises is to direct the person's attention to another source while the first task is being performed. When the literature is examined, there are separate studies on the effects of dual-task exercises on both balance and walking performance and cognitive functions. However, the meta-analyses conducted on these studies emphasize the need for more newly designed studies. Therefore, our study aims to examine the effects of dual-task exercise training, which includes both physical and cognitive parameters, on cognitive functions, balance and functionality in individuals with type 2 diabetes. Patients who applied to the Artvin State Hospital Internal Medicine polyclinic and were diagnosed with type 2 diabetes and who meet the inclusion and exclusion criteria will be included in our study. The patients included in the study will be divided into 3 groups: dual-task exercise group, single-task exercise group and control group. Both intervention groups will be included in an exercise program with a physiotherapist 2 days a week for 8 weeks in addition to their medical treatments. The control group will be recommended walking only in addition to their medical treatment during these 8 weeks. All 3 groups will be evaluated twice, at the beginning of the study and at the end of the 8th week.

Подробное описание

Diabetes Mellitus is defined as a carbohydrate mechanism disorder in which glucose cannot be used as an adequate energy source and is overproduced, causing hyperglycemia. Diabetes is diagnosed by an increase in HbA1c in the blood or a high glucose concentration in venous plasma. Although there are various clinical subtypes, Type 2 diabetes accounts for 90% of the approximately 537 million diabetics worldwide. In the treatment of diabetes, there are pharmacological treatments and lifestyle changes to achieve glycemic control. The most important lifestyle change interventions are balanced calorie intake, increased physical activity and regular exercise.

The effect of exercise on complications associated with Type 2 diabetes, such as improving glycemic control, reducing inflammation and reducing cardiovascular risk, is clear and is known to affect cognitive functions.

Loss of postural balance is a significant problem frequently observed in patients with T2DM. Balance is defined as the individual's capacity to maintain or regulate the center of mass within the limits of balance. In this process, the integration of physiological systems including motor, sensory and dynamic control systems, vestibular, visual and proprioceptive mechanisms, muscle strength and reaction times plays a critical role. Although balance dysfunctions are generally attributed to diabetic peripheral neuropathy (DPN), balance disorders are also observed in individuals without DPN. Impaired balance function increases the risk of falling, especially in elderly T2DM patients.

However, an important problem that is frequently observed in T2DM patients but can be neglected is cognitive dysfunction. Cognitive dysfunction is a broad concept that encompasses deficiencies in various areas such as attention, memory, executive functions, language and spatial skills. Diabetes and cognitive dysfunction are chronic conditions that are frequently seen together, especially in elderly individuals, and when evaluated together, they significantly increase the risk of morbidity and mortality. Cognitive impairment can lead to serious difficulties in meeting the self-care needs of diabetic individuals and maintaining their economic and social independence. On the other hand, inadequate management of diabetes can also increase the risk of cognitive dysfunction and cause this situation to worsen.

In this context, dual-task exercises that can target both the improvement of parameters related to postural control and balance as physical development and the development of cognitive functions are gaining importance. Therefore, our study aims to examine the effects of dual-task exercise training, which includes both physical and cognitive parameters, on cognitive functions, balance and functionality in individuals with type 2 diabetes.

Patients who apply to the Artvin State Hospital Internal Medicine polyclinic and are diagnosed with type 2 diabetes and meet the inclusion and exclusion criteria will be included in our study. The patients included in the study will be divided into 3 groups: dual-task exercise group, single-task exercise group and control group.

Each of the 3 groups will be evaluated twice, at the beginning of the study and at the end of the 8th week.

Вмешательства

• Другое Single Task Exercise
  Patients will follow the exercises in a way to focus on only one task during the exercise sessions. In the creation of the exercise programme, the principles of the exercise prescription recommended by the American Sports Medicine Association for individuals with adult Type 2 diabetes will be taken into consideration. In this context, planning will be made by considering the progression of stretching, balance and walking exercises from simple to difficult.
• Другое Dual Task Exercise
  Patients enrolled in the dual-task exercise group will perform a second task during the exercise sessions along with the exercises in the single-task exercise group. This second task will be determined individually according to the level and progress of the patient.
