About this study
Official title: Associations of Respiratory Muscle Strength and Trunk Muscle Mechanical Properties With Dynamic Postural Control in Healthy Young Adults: A Cross-sectional Study
This study will examine the associations of respiratory muscle strength and trunk muscle mechanical properties with dynamic balance and limits of stability in healthy young adults. The research will enroll healthy volunteers between the ages of 18 and 30. Participants will undergo assessments to measure their maximal inspiratory and expiratory pressures, as well as the tone and stiffness of their abdominal and lumbar paraspinal muscles. Additionally, the participants will complete computerized balance tests to evaluate their voluntary weight-shifting capabilities and their stability on a moving surface. Ultimately, the findings will determine whether evaluating these respiratory and trunk muscle characteristics will effectively complement standard clinical balance assessments.

Myotonometry, Respiratory Muscle Strength Testing, and Computerized Balance AssessmentOther
Participants will undergo three specific assessments during a single morning session: Trunk muscle mechanical properties: The muscle tone and dynamic stiffness of the lumbar paraspinal and rectus abdominis muscles will be assessed bilaterally using a handheld digital myotonometer (MyotonPRO). Respiratory muscle strength: Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) will be evaluated using an electronic mouth pressure device (MicroRPM). Postural control: Balance will be assessed using a computerized balance system (Prokin 252) through two distinct tests: the Limits of Stability (LOS) test to evaluate voluntary dynamic balance and weight-shifting capability, and the Dynamic Bipedal Balance Test (DBBT) to measure postural stability on a multiaxial oscillating surface.
