Final answer:
Over rotation of an oblique L-spine is indicated by abnormal curvatures such as kyphosis, lordosis, and scoliosis. These conditions can be identified through side and back profile observations, and by examining the evenness of the back while the person bends forward.
Step-by-step explanation:
Over rotation of an oblique L-spine is indicated by abnormal or excessive curvatures observed in the spine's anatomical position, specifically in the lumbar region. To identify if over rotation has occurred, one should check from the side and behind for signs of kyphosis (excessive posterior curvature) or lordosis (excessive anterior curvature).
Furthermore assessing the individual when they bend forward can reveal scoliosis, noted by an abnormal lateral bending and uneven level of the back. Excessive vertebral curves like kyphosis can develop due to conditions such as osteoporosis, which affects the thoracic vertebrae, or from obesity and pregnancy in the case of lordosis. A pronounced lumbar curve may also result from an anterior tilt of the pelvis. In contrast scoliosis is a lateral curvature combined with a twisting of the vertebral column, often seen in adolescent growth spurts and may require intervention with a back brace or surgery in severe cases.
