When examining the lumbar spine from the side view, which vertebrae should be felt for curvature?

When examining the lumbar spine from the side view, the focus is on the curvature of the lumbar region, which includes the vertebrae L1 to L5. This area is particularly significant because it is where the natural lordotic curve of the spine is observed. The lumbar vertebrae are responsible for supporting the weight of the upper body and are crucial in contributing to the overall alignment and stability of the spine during movement and various activities.

The lumbar region has a characteristic anterior convexity that is essential for effective load distribution and functional movement. A thorough understanding of the lumbar curvature allows practitioners to assess posture and identify any deviations or abnormalities that could lead to discomfort or injury.

Other regions of the spine, such as the cervical (C1 to C7) and thoracic (T1 to T6 and T6 to T12), have their own distinct curvatures and functions, but they are not relevant when focusing specifically on the lumbar curvature from the side view. Thus, the emphasis on L1 to L5 for curvature analysis is critical for proper postural assessment and Pilates practice.
