The psoas is considered deep core muscles and, together with the iliacus, are the main flexors of the hip, the muscles that are activated when lifting your thigh towards your trunk or when moving your trunk forward towards your hip. Unlike the quadriceps, hamstrings, and glutes which are commonly known, the psoas muscle is less commonly heard of but does serve important functions. Although this muscle plays a vital role in different lower limb movements, it acts mainly to stabilize the lower back region in various activities, such as during walking or bending forward. With this function in core stability, it is prone to cause low back pain.
THE TIGHT PSOAS AS THE CAUSE OF LOW BACK PAIN.The hip flexors become tight in people who engage in activities that require sitting for extended periods, like those who live a more sedentary lifestyle and spend a lot of time sitting or those who work at an office job for hours. When the psoas muscle becomes tight, it pulls the small of the back forward, causing excessive hollowing or curving of the lower back region — termed as lordosis. This postural orientation stresses the lower back structures, causing hip and low back pain, as well as limitations in hip and trunk movements.
THE PSOAS STRETCH. Several psoas stretches have been recommended to release tightness in the psoas muscle and relieve tension in the lower back. The exercises mainly consist of bringing the affected hip into extension, such as in lunging. The lunge stretch involved the patient stepping forward with the foot of the unaffected side while keeping the opposite foot (of the affected hip) flat on the ground. Keeping the body straight and erect, the patient is instructed to move the body forward by advancing the knee forward but not going beyond the toes until feeling a stretch in the low back. The position is held for 30 seconds before returning to the starting position. The procedure is repeated several times for 3 to 5 sets.
THE PSOAS RELEASE WITH RECOVAPRO
Using the Recovapro massage gun before flexibility exercises help to loosen the tight psoas so that stretching of the muscle can be more easily performed.
