Abstract
BackgroundThe cross-legged sitting posture (CLS) is assumed by young adults’ results in a bent and unbalanced posture. The study purpose was to assess the effect of sitting in a cross-legged position (knee on knee) on lumbar proprioception. Thirty-six participants of both genders aged from 18 to 25 were selected and divided equally into group A who adapt to a cross-legged sitting posture and group B who adapt to erect sitting (not prefer cross-legged sitting). The Biodex System 3 pro isokinetic dynamometer was utilized to assess the lumbar proprioception by testing the lumbar region repositioning accuracy.ResultsThe lumbar repositioning error of group A increased statistically significantly as compared to group B (p < 0.05).ConclusionsCross-legged sitting posture negatively affects lumbar proprioception compared with participants who adapt to erect sitting, and this effect should be considered in the avoidance of sitting in a cross-legged position and in prevention and intervention programs of lumbar proprioception impairment.

The cross-legged sitting posture (CLS) is assumed by young adults’ results in a bent and unbalanced posture
Most young adults rely on automobiles, even for shortdistance transport, and work or play video games on computers and other screen time activities like watching television [1], and sitting while maintaining knees crossed is an example of popular asymmetric sitting positions [2]
Several studies had been conducted to determine the morphological and functional changes in people who adapted to sitting in a cross-legged position, but there was a literature gap in the effect of sitting in a crosslegged position on lumbar proprioception
Summary
The cross-legged sitting posture (CLS) is assumed by young adults’ results in a bent and unbalanced posture. Cross-legged sitting posture has several physiological benefits, such as reducing external and internal obliques muscle fatigue and providing sacroiliac joint stability [3], and subject may find it comfortable, but when an asymmetric position becomes habitual, it has the potential to cause musculoskeletal symptoms and disease [4]. Proprioception is an essential aspect of the somatosensory system that gives afferent information on joint position and movement in normal human performance [5]. It plays major functions in feedback control, as well as muscle stiffness management. All of these factors have a role in maintaining joint stability. Musculoskeletal problems such as pain and fatigue have caused proprioception dysfunction [6]
