Final answer:
Tightening of the psoas muscle can cause lower back pain. Prolonged sitting and poor posture can contribute to psoas tightness. Stretching and strengthening exercises can help relieve lower back pain caused by a tight psoas muscle.
Step-by-step explanation:
Tightening of the psoas muscle can indeed cause lower back pain. The psoas muscle is a deep muscle that runs from the lower spine to the upper thigh, and when it becomes tight or shortened, it can pull on the lower back, leading to pain and discomfort. This is especially true if someone spends a lot of time sitting or has poor posture, as these factors can cause the psoas muscle to become tight.
An example of how psoas tightness can cause lower back pain is when someone sits for long periods with their hip flexed and their knees bent, such as when working at a desk. In this position, the psoas muscle remains in a shortened state, causing it to tighten. Over time, this can lead to imbalances in the muscles around the pelvis and lower back, resulting in pain.
Stretching and strengthening exercises can help release and balance the psoas muscle, relieving lower back pain. Regular stretching routines can help keep the psoas muscle flexible and prevent tightness from forming in the first place.
