Investigation of Exercise Capacity, Muscle Oxygenation and Physical Activity Level in Parkinson's Patients

Gazi University56 enrolled

Overview

The primary aim of this study is to compare maximum and functional exercise capacity and muscle oxygenation during exercise test in patients with Parkinson's disease. The secondary aim is to evaluate respiratory functions, respiratory muscle strength and endurance, peripheral muscle strength, physical activity level, shortness of breath and fatigue in Parkinson's patients and compare with healthy individuals.

Parkinson's disease is the second most common neurodegenerative disease. The main motor symptoms in Parkinson's disease are tremor, rigidity, bradykinesia, and decreased postural reflexes, and respiratory problems are seen that cause mortality. Disturbances in the control of the epiglottis, laryngeal and pharyngeal muscles may cause aspiration pneumonia. The coughing or exhalation reflex requires coordinated motor activity and inadequate airway defense poses a risk for pneumonia. Upper airway obstruction may occur due to rigidity and fatigue in the thyroarytenoid muscles. It can cause a decrease in lung volumes and thus the development of restrictive respiratory function abnormality. Pulmonary functions, exercise capacity, respiratory muscle strength and endurance, peripheral muscle strength, physical activity level and fatigue were affected in patients. The number of studies on these subjects is limited. Mitochondrial dysfunction in Parkinson's patients has been proven in several studies. There is no study in the literature evaluating muscle oxygenation at rest and during exercise in Parkinson's patients. The primary aim of this study is to compare maximum and functional exercise capacity and muscle oxygenation during exercise test in patients with Parkinson's disease. The secondary aim is to evaluate respiratory functions, respiratory muscle strength and endurance, peripheral muscle strength, physical activity level, shortness of breath and fatigue in Parkinson's patients and compare with healthy individuals. The study was planned cross-sectional. Patients with Parkinson Disease referred to the Cardiopulmonary Rehabilitation Unit of Gazi University Physiotherapy and Rehabilitation Department by the physicians of the Neurology Department of Gazi University Faculty of Medicine will be included in the study. At least 26 patients with Parkinson Disease and at least 26 healthy controls of similar age and sex will be evaluated in the study. The assessments will be completed in two days. Upper extremity exercise capacity (6 minutes Pegboard and Ring Test), muscle oxygenation ("Moxy" monitor), functional exercise capacity(6 minutes walk test), respiratory functions (spirometer), respiratory muscle strength (mouth pressure measurement), respiratory muscle endurance (incremental threshold loading test), peripheral muscle strength (dynamometer), physical activity level (multi-sensor activity monitor) and fatigue (Parkinson's Fatigue Scale) will be evaluated.

Outcomes

Primary Outcomes

Lower extremity exercise capacity

Lower extremity exercise capacity will be evaluated with six- minute walking test. The test will be performed according to the criteria of the American Thoracic Society and the European Respiratory Society.

Time frame: First Day

Upper extremity exercise capacity

Upper extremity exercise capacity will be evaluated with the six-minute pegboard and ring test (6-PBRT). A pegboard with two upper and lower bars set at participants shoulder level and above the shoulder level will used. Ten rings will placed on both the lower bars. Patients will be asked to move a single ring at a time with both hands from the lower bars to the upper. The score is the total number of rings moved the six-minute period.

Time frame: Second Day

Muscle Oxygenation

Muscle oxygenation assessment will be performed using the Moxy monitor (Moxy, Fortiori Design LLC, Minnesota, USA). The device will be placed on the 1/3 lower motor point of the quadriceps muscle group of the dominant leg and on the dominant arm deltoid muscle. A minimum of 3 minutes will be waited until the resting measurements and skeletal muscle oxygenation (StO2) signal stabilize. The measurements will be repeated during six minute walking test and six minute pegboard and ring test.

Time frame: First and Second Day

Secondary Outcomes

Respiratory muscle strength

Maximal inspiratory (MIP) and maximal expiratory (MEP) pressures expressing respiratory muscle strength will be measured with a portable mouth pressure measuring device according to American Thoracic Society and European Respiratory Society criteria.

Time frame: First day

Respiratory muscle endurance

Respiratory muscle endurance will be assessed by the POWERbreathe Wellness (POWERbreathe, Inspiratory Muscle Training (IMT) Technologies Ltd., Birmingham, UK) device and the respiratory muscle endurance test at increased threshold load. The test will be started with 20% of the maximal inspiratory pressure and the pressure will be increased to 40%, 60%, 80% and 100% every two minutes. Patients will be asked to continue breathing through the device during the test. If the individual cannot breathe 3 consecutive times, the test will be terminated by the physiotherapist. During the test, the number of breaths delivered and the maximal time reached during each 2-minute period will be recorded.The total duration of the test and the maximum pressure value at which it continues to breathe for at least 1 minute will be multiplied. The value found will be recorded as the respiratory muscle endurance value.
