Study: NCT05520216

Intervention type: DEVICE
Intervention: Spinal mouse (idiag m360)
Description: A noninvasive Spinal Mouse device will be used to measure the thoracic kyphosis and lumbar lordosis angle of the spinal column in the sagittal plane. It will be displayed on the computer aided software screen where the thoracic and lumbar region angles are calculated by swiping over the spinal processes from top to bottom with the Spinal Mouse (IDIAG m360) device. Measurements will be taken while standing on a flat surface. The volunteer will take off his upper clothes and shoes during the examination. Relax your arms and torso will be positioned next to you. The distance between the feet will be approximately waist width and parallel to each other, the knees will be straight and face motionless. He will stand where he feels comfortable. A Spinal Mouse examination will be performed and data will be recorded.

Intervention type: BEHAVIORAL
Intervention: chest circumference measurement
Description: Measurements will be taken from the axillary (4th rib level - two fingers below the axilla), epigastric (xiphoid process level) and subcostal (9th rib level) regions at the time of normal, maximal inspiration, and maximal expiration using a tape measure while the patient is in a sitting position. The tape measure will be placed in the area to be measured. Care will be taken that there is no folding or horizontal level difference in the tape measure and that the fingers are not under the tape measure. Normal respiration will be measured first and recorded in centimeters (cm). The patient will then be asked to take a deep, long breath towards the bottom of the tape measure. The value obtained will be recorded as the deep inspiration value. Immediately after deep inspiration, the patient will be asked to make a deep and long expiration. The obtained value will be recorded as deep expiration.

Intervention type: BEHAVIORAL
Intervention: Maximum Breath Hold Test
Description: During the breath-hold measurement, the subject will sit in a chair with a backrest. He will take a deep breath through his nose. We do not want maneuvers (Valsalva and Müller) and diaphragm contractions that will affect the breath-hold time, so volunteers will be observed throughout the test. The test will be terminated as soon as involuntary diaphragm contractions are seen. This test will be applied 3 times by resting the volunteer with breaks for 5 minutes. The average of 3 test results will be taken (Lin, Y. C.: Effect of O2 and CO2 on breath hold breaking point. In The Physiology of Breath Hold Diving. (eds): CEG Lundgren, M Ferringo, Undersea and Hyperbaric Medical Society Inc, Bethesda, Maryland, p: 75-87 1987.).

Intervention type: BEHAVIORAL
Intervention: Sit and Reach
Description: While the participant is sitting on the floor with his back to the wall and his legs are fully extended in front of him, his knees should be in full contact with the floor. The box will be placed on the sole of the participant's feet (without shoes) in full contact with the volunteer's feet. The participant will be instructed to lean forward as slowly as possible, keeping their fingertips level with each other and their legs straight on the floor. He will be asked to slowly lie down along the ruler three times, and on the third attempt the volunteer will be instructed to reach out as far as possible and hold for 2 seconds. This value will be saved
