Mechanical Properties of Peripheral and Accessory Respiratory Muscles in Chronic Obstructive Pulmonary Disease Patients

All evaluations will be performed with a MyotonPRO (Myoton AS., Tallinn, Estonia) digital palpation device. The data of the cases to be evaluated and the patterns related to the measurements will be transferred to the device by establishing a computer connection. Measurements will be performed unilaterally. The measurement point of the subjects' unilateral muscles will first be marked with a pencil. The physiotherapist will hold the device vertically and apply downward pressure (18N) to the muscle body. When the red light on the plexiglass frame of the device probe turns green, the pressure application will be stopped and will remain constant until 5 strokes are made. In every 5 beats, the duration of 1 beat is 15 ms and the time between beats is 8 ms. The SENIAM sensor location guide will be considered as a reference for the estimated motor point determination in the MyotonPRO measurement.
