简要总结
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.
详细描述
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:
- Preventing Musculoskeletal Disorders
- Excessive knee valgus increases knee injury risk.
- Abnormal lumbar curvature (hyper lordosis) may alter lower limb kinematics, contributing to knee malalignment.
- Improving Rehabilitation Strategies: If lumbar posture influences knee mechanics, interventions (such as core stabilization) could reduce valgus and injury risk.
- Ergonomics: Sedentary lifestyles and poor posture may exacerbate both spinal misalignment and knee valgus, increasing osteoarthritis risk.

研究组 & 干预措施
Smartphone Addict With Non Specific Low Back Pain
Sixty-eight subjects who are Smartphone Addict With Non Specific Low Back Pain and aged from 18 to 25 years old will be allocated into one group
结局指标
主要结局
Lumbar spinal curvature
时间窗: 8 weeks
Kinovea software program will be used to assess lumbar curvature mainly the cobb angle of lumbar lordosis. Colored markers can be placed on key anatomical landmarks ( spinous processes of L1-L5) while the subject stands in a relaxed, natural posture with feet shoulder-width apart. the image will be captured from a lateral (side) view of the spine. and the Kinovea software will analyze and measure angle. Normal Lumbar Lordosis: \~30-60° (varies by method), hyperlordosis: \>60° (excessive curvature), hypolordosis (Flat Back): \<30° (reduced curvature).
次要结局
- Assessment of pain intensity(8 weeks)
- Assessment of smart phone addiction(8 weeks)
- Assessment of quadriceps muscle strength(8 weeks)
- Assessment of dynamic knee valgus angle(8 weeks)
