Outcome Measures
Primary Outcomes (1)
Lumbar spinal curvature
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).
