Low back pain? Walk your hands up your legs when you go from sitting to stand? Hip pain? Knee pain? Feel uneven? This could be your reason.
The iliopsoas is an essential muscle group for overall body function, stability, and movement, acting as the primary connector between your torso and your lower body. It is composed of the psoas major and the iliacus muscles. Its primary functions include flexing the hip, stabilizing the lower back, and enabling fundamental movements like walking, running, and sitting upright.
Core functions and importance
Hip flexion:
As the strongest hip flexor, the iliopsoas lifts the legs toward the torso. This action is critical for many daily activities, such as walking, running, climbing stairs, and getting up from a chair.
Postural support:
The psoas muscle originates from the lumbar spine and plays a key role in stabilizing the spine and pelvis. It supports the lumbar lordotic curve (the natural inward curve of the lower back) and helps maintain an upright, balanced posture while standing or sitting.
Core stability: Working with other core muscles, the iliopsoas helps stabilize the pelvis and spine. This stability is crucial for distributing the weight of the upper body over the hips and legs during movement, which helps prevent injuries.
Connection between upper and lower body: The iliopsoas connects the torso to the legs, allowing for efficient movement from your center of gravity. This deep-seated connection affects the quality and ease of your motion.
Impact of iliopsoas dysfunction:
Because of its central role, issues with the iliopsoas can lead to a variety of problems, including chronic pain and reduced mobility.
Pain and limited mobility: A tight, shortened, or weak iliopsoas can pull on the lumbar spine, leading to lower back pain, hip discomfort, and a limited range of motion.
Postural imbalances: Prolonged sitting can cause the iliopsoas to become short and tight. This can result in an excessive anterior pelvic tilt, which in turn increases the lumbar curve (hyperlordosis) and puts added stress on spinal discs and joints.
Hip and groin issues: Overuse from repetitive hip flexion, common in athletes such as dancers, runners, and soccer players, can cause iliopsoas tendinitis or bursitis. A clicking or snapping sensation in the hip can also occur with this condition.
Compensatory problems: When the iliopsoas is tight, other muscles in the back, hips, and legs may be forced to overcompensate. This can lead to imbalances and pain in seemingly unrelated areas, including the knees, buttocks, and hamstrings.
