INTRODUCTION

In the last decade obesity has been recognized as a major world health problem characterized by an alarming growing rate and an‌ important‌ risk factor for various pathologies. The excessive amount of fat modifies the body geometry by adding passive mass to different regions and it influences the biomechanics of activities of daily‌ living‌, causing functional limitations, and possibly predisposing to injury. Balance is defined as the process that maintains the center of gravity within the body’s support base and requires constant adjustments‌ that‌ are provided by muscular activity and joint positioning. Most nervous and musculoskeletal system diseases can alter this balance control. Maintaining postural balance requires sensorial detection of the body’s movements‌, integration‌ of‌ sensory-motor information into the‌ central‌ nervous‌ system and an appropriate motor response. The position of the body in relation to space is determined by visual, vestibular and‌ somatosensory‌ functions‌. Muscular control and dynamic maintenance of balance involve‌ the‌ activity of coordinates of muscular kinetic chains. Constraints on postural stability in healthy subjects arise by mechanical factors, including‌ individual‌ and‌ environmental factors, Therefore body physical properties may affect postural stability‌.
