In lower crossed syndrome, a patient's abdominal muscles are assessed as weak. Which of the muscles are likely to test weak?

In lower crossed syndrome, the condition is characterized by specific patterns of muscular imbalances. In this syndrome, the abdominal muscles are often weak, particularly the rectus abdominis and the obliques. As a result, the hip flexors, such as the iliopsoas, can become tight and overactive due to this weakness, leading to improper posture and movement patterns.

The gluteus maximus plays a crucial role in stabilizing the pelvis and supporting hip extension. When the abdominal muscles are weak, this can diminish the effectiveness of the gluteus maximus, making it more likely to also test weak. The imbalance creates a pattern where the glutes are unable to function optimally, contributing to the lower crossed syndrome's hallmark findings.

Understanding this interaction highlights the importance of addressing muscle weaknesses and imbalances in treatment and rehabilitation, as strengthening the abdominal muscles can help restore the function of the gluteus maximus and improve overall lower body mechanics.
