Psoas syndrome is primarily caused by which action?

Psoas syndrome is primarily associated with the action of hip flexion. The iliopsoas group, which includes the psoas major and iliacus muscles, is primarily responsible for the flexion of the hip joint. When the psoas muscle becomes tight or overactive due to prolonged postures or movements that require hip flexion, it can lead to discomfort in the lower back and pelvis, resulting in Psoas syndrome.

This condition often arises in individuals who spend a lot of time sitting or engaging in activities that require repetitive hip flexion, such as running or cycling. Prolonged hip flexion can cause the psoas to adapt by becoming tight, which can lead to an imbalance between the hip flexors and other muscle groups, subsequently affecting posture and creating pain.

Understanding the mechanics of hip flexion and its role in Psoas syndrome provides insight into the importance of maintaining muscle balance and flexibility in the hip region to prevent this condition from developing.
