Summary

The purpose of this study will be to investigate the relation between degree of lumbar spine curvature and dynamic knee valgus angle in smartphone addict students with non-specific low back pain.

Detailed description

Smartphone usage can potentially cause musculoskeletal disorders in the lower back. Continuous smartphone use has been shown to create proprioception impairments in the cervical vertebra and postural alterations in the cervical and lumbar vertebrae (slouched posture) Understanding the relationship between lumbar spine curvature (hyperlordosis, hypolordosis) and knee valgus angle is crucial for: 1. Preventing Musculoskeletal Disorders * Excessive knee valgus increases knee injury risk. * Abnormal lumbar curvature (hyper lordosis) may alter lower limb kinematics, contributing to knee malalignment. 2. Improving Rehabilitation Strategies: If lumbar posture influences knee mechanics, interventions (such as core stabilization) could reduce valgus and injury risk. 3. Ergonomics: Sedentary lifestyles and poor posture may exacerbate both spinal misalignment and knee valgus, increasing osteoarthritis risk.
