Final answer:
To assist a client with lordosis, exercises targeting the multifidus muscle and iliopsoas group are essential for stabilizing the lumbar spine and correcting posture.
Step-by-step explanation:
When addressing a client suffering from lordosis, a condition characterized by an exaggerated inward curve of the lumbar spine, it's important to focus on certain interior muscles to help manage and potentially correct the posture. The multifidus muscle of the lumbar region is particularly significant as it assists in extending and laterally flexing the vertebral column, therefore playing an essential role in stabilizing the lumbar spine. In addition to the multifidus, working on the iliopsoas group, which includes the iliacus and psoas major muscles, is crucial. These muscles are responsible for flexing the thigh at the hip, rotating it laterally, and flexing the trunk of the body onto the hip.
