Hip Flexors & Pelvic Dysfunction

The hip flexor muscles include the Iliopsoas group (Psoas Major, Psoas Minor, and Iliacus), Rectus Femoris, Pectineus, Gracillis, Tensor Fascia Latae, and Sartorius. When the hip flexors are tight it can cause tension on the pelvic floor. This can pull on the lower back and pelvis as well as change the orientation of the hip socket, lead to knee pain, foot pain, bladder leakage, prolapse, and so much more. The ramifications of iliacus and iliopsoas dysfunctions are discussed in Ramona Horton's visceral course series:

• Mobilization of the Visceral Fascia - The Urinary System
• Mobilization of the Visceral Fascia - The Reproductive System

A common issue with the iliacus and hip flexors is that they can shorten over time due to a lack of stretching or a sedentary lifestyle. When this happens, the muscle adapts by becoming short, dense, and inflexible and can have trouble returning to its previous resting length. A muscle that resides in this chronic contraction can become ischemic, develop trigger points, and distort movement in the body.

If you are treating patients with pain in their lower abdomen, sacroiliac joint, or that wraps around the lower back and buttocks, it could be because the hip flexors are tight. Traditional testing performed by medical practitioners tends to come back negative as many tests do not evaluate soft tissue issues. The best way to diagnose these concerns is through assessment with skilled palpation and structural evaluation.

One assessment test used for the iliopsoas is discussed in the Athletes & Pelvic Rehabilitation course. This is the Thomas Test which measures the flexibility of the hip flexors. In this test, the patient is supine while flexing the unaffected, contralateral leg at the hip until lumbar lordosis disappears. The length of the iliopsoas is determined by the angle of hip flexion displayed by the patient. The test is positive when the patient is unable to keep their lower back and sacrum against the table, the hip has a posterior tilt (or hip extension) greater than 15°, or the knee is unable to meet more than 80° flexion. A positive test indicates a decrease in flexibility iliopsoas muscles.

Treatment plans for the iliacus and hip flexors include stretching. An example includes the hip extension stretch or other active isolated stretches. Manual therapy, including trigger point release, can be used in conjunction with stretching to help muscle adhesion and release muscle tension. As with all treatment, the practitioner should discuss the risks, benefits, and treatment options, and obtain consent with patients. Prior to proceeding with manual therapy treatment make sure to establish a pain scale, assess the patient's range of motion and strength, and (if needed) perform the appropriate neurologic testing.
