Validity and Reliability of the 6-Minute Pegboard and Ring Test in Patients With Coronary Artery Disease

Coronary artery disease, a cardiovascular disease, causes significant mortality and morbidity. Due to the impairment of arterial blood flow in coronary artery disease, the heart muscle cannot receive an adequate blood supply during exercise, resulting in symptoms such as chest pain, shortness of breath, and fatigue, which can lead to a decrease in exercise capacity. The 6-Minute Pegboard and Ring Test is a simple, rapid, and inexpensive assessment tool used to evaluate upper extremity exercise capacity. The purpose of this study was to assess the validity and reliability of the 6-Minute Pegboard and Ring Test in patients with coronary artery disease.

Within the scope of the study, at least 32 patients diagnosed with coronary artery disease (CAD) will undergo the "6-Minute Pegboard and Ring Test" (6-PBRT), which assesses upper extremity functional exercise capacity, and the upper extremity cardiopulmonary exercise test, which assesses maximal exercise capacity, on two separate days, 48 hours apart. The 6-Minute Pegboard and Ring Test will be repeated twice, 1 hour apart, by the same evaluator. Before and after the test, heart rate (HR), oxygen saturation, respiratory frequency, arm fatigue, general fatigue, and dyspnea parameters will be assessed. In the 6-PBRT, heart rate and oxygen saturation will be measured with a pulse oximeter (Soulfix Fingertip Oximeter Pulse Oxygen Meter, ABD); fatigue and dyspnea will be assessed with the Modified Borg Scale (MBS); and respiratory frequency will be assessed by counting the number of breaths taken per minute. Patients' respiratory muscle strength will be assessed using a portable oral pressure monitor (Micro Medical MicroRM, UK); respiratory function tests will be performed using a spirometer (Cosmed, Class II/Internally Powered Equipment, Italy); and peripheral muscle strength will be assessed using a portable handheld dynamometer (JTECH Power Track Commander, Baltimore, USA). Patients' quality of life will be assessed using the "Heart Quality of Life Scale in Coronary Artery Disease Patients." All assessments and tests will be explained in detail to the patient beforehand.
