Which abnormal curve is commonly found in the frontal plane?

The abnormal curve commonly found in the frontal plane is scoliosis. Scoliosis is characterized by a lateral deviation of the spine, which means that the spine curves to the side. This condition typically manifests as an S or C shape when viewed from the back or front, making it distinctly a frontal plane issue.

In contrast, lordosis and hyperkyphosis are spinal curvatures associated with the sagittal plane. Lordosis refers to an exaggerated inward curvature of the lumbar spine, while hyperkyphosis involves an excessive outward curvature of the thoracic spine. Ischemia, on the other hand, refers to the lack of blood flow to a tissue and is not a spinal condition related to abnormal curvature. Understanding the differences in the planes of motion and the types of spinal deformities is essential for recognizing and addressing various postural issues.
