Brief Summary

The aim of this study is to compare the effectiveness of motor-motor dual-task training and cognitive-motor dual-task training in patients with Parkinson's disease.The main questions it aims to answer are: \- Whether there is a difference between motor-motor dual-task training and cognitive-motor dual-task training in patients with Parkinson's disease in terms of their effects on motor symptoms, balance, gait, functional mobility, activities of daily living, dual-task activities, cognitive functions, and balance confidence. Researchers will compare single-task training, motor-motor dual task training and cogvitive-motor dual task training. Participants will:

• Receive exercise training at the study clinic twice a week for approximately 45 minutes each time, for 6 weeks.
• Participate in assessments at the study clinic before and after exercise training.

Outcome Measures

Primary Outcomes (12)

• Unified Parkinson's Disease Rating Scale (UPDRS) - PART 3

  UPDRS is a reliable and valid scale that assesses cognitive skills, mood, daily living activities, motor skills, motor fluctuations, dyskinesias and autonomic dysfunction and is widely used in clinical studies and research in Parkinson's disease. The motor symptoms section, which is the third section of this scale, will be used.

  From enrollment to the end of training at 6 weeks

• Hoehn & Yahr Scale

  It is a staging system that provides information quickly in determining the severity and symptoms of Parkinson's disease.

  From enrollment to the end of treatment at 6 weeks

• Single-Leg Stance Test

  This is a test method used to assess static balance. The patient's preferred foot is raised without touching the supporting leg, and initially, the eyes are open. The eyes are fixed towards the head, and the patient is expected to maintain their balance for 60 seconds. The time the participant maintains their balance is recorded.

  From enrollment to the end of treatment at 6 weeks

• Functional Reach Test

  This test is designed to assess dynamic balance. In the test, the participant is positioned sideways next to a wall, with their torso upright, the shoulder on the wall flexed to 90°, and the elbow fully extended. The participant is then asked to make a fist with the same arm, and the position of the third metacarpal head is marked on the wall. The participant reaches forward with their knees fully extended; the position of the third metacarpal head is marked again, and the participant returns to the starting position. The difference between the two marks is measured with a tape measure.

  From enrollment to the end of treatment at 6 weeks

• 10 Meter Walking Test

  Participants are asked to walk at normal walking speed for a distance of 10 meters and the time is recorded.

  From enrollment to the end of treatment at 6 weeks

• Motor-Motor Dual Task Cost of Walking

  To assess the motor-motor dual-task cost of walking, patients will perform the 10-meter walk test once as a single task and once while holding an empty plate on a tray in their hands. The dual-task cost will be calculated as a percentage using the following formula: \[(Dual-task performance - Single-task performance)/ (Single-task performance) x 100\]

  From enrollment to the end of treatment at 6 weeks

• Cognitive-Motor Dual Task Cost of Walking

  To assess cognitive-motor dual-task cost of walking, patients will perform the 10-Meter Walk Test once as a single task and once as a dual-task test, counting backwards in increments of 7 from a three-digit number greater than 300. Dual-task cost will be calculated as a percentage using the following formula: \[(Dual-task performance - Single-task performance)/ (Single-task performance) x 100\]

  From enrollment to the end of treatment at 6 weeks

• Timed Up and Go Test

  This test is used to assess functional mobility levels. The test involves using a standard chair with the individual's knees flexed at 90° and their backrest against it. The individual is asked to stand up from the chair, walk 3 meters, turn around, and then walk back to the chair and sit down. The test begins with the command "walk," and the test duration is measured with a stopwatch and recorded in seconds.

• Unified Parkinson's Disease Rating Scale (UPDRS) - PART 2

  It consists of thirteen items. The assessment is based on anamnesis information regarding how the patient functions in various activities. The presence of sensory complaints that may be related to tremor and parkinsonism is also included in this section as they can affect daily living activities. Each item is evaluated using a scoring system between '0' and '4'.

  From enrollment to the end of treatment at 6 weeks

• Dual Task Questionnaire

  This test is used to assess the challenges encountered in daily tasks involving dual work. It consists of 10 questions and is administered via face-to-face interview. Each question is scored between 0 and 4. A score of "4" indicates frequent challenges, while a score of "0" indicates no challenges.

  From enrollment to the end of treatment at 6 weeks

• Trail Making Test

  It is used to assess executive functions and attention. The test consists of two parts, A and B. In part A, the individual is asked to combine numbers from 1 to 25, and the completion time is recorded. In part B, the individual completes a sequence where each number corresponds to a letter, and the completion time is recorded.

  From enrollment to the end of treatment at 6 weeks

• Activity-Specific Balance Confidence Scale

  This is a commonly used scale for assessing balance confidence. The scale evaluates whether individuals believe they can perform daily living activities without losing their balance or becoming unsteady. It consists of sixteen items. Each item is scored between a minimum of "0" (unconfident) and a maximum of "100" (completely confident). The base score is calculated by dividing the total score by 16. Higher values indicate that the person feels good about their balance, while lower values are associated with an increased risk of falls.
