The obturator internus can become tensioned or spasmed from overworking, muscle imbalances, injuries, and postural changes. Some symptoms of obturator internus muscle tension include: Hips that feel tight and your feet always seem to be rotated out. Lateral hip pain, can be mistaken for IT band syndrome/bursitis.
Moreover, Where does the obturator internus muscle originate?
The obturator internus muscle is found on the superior inner side of the obturator membrane. The obturator internus muscle originates from the inferior margin of the superior pubic ramus and from the pelvic surface of the obturator membrane.
Secondly, What happens when a trigger point is released?
One theory states that trigger points form from excessive release of a chemical called acetylcholine, which produces a sustained depolarization of muscle fibers, leading to a sustained contraction of the muscle fibers.
Simply so, What does the obturator Internus do?
The obturator internus (OI) is a hip muscle that originates deep within the pelvis, wraps out and inserts on the posterior aspect of the head of the femur (the thigh bone). The OI’s main function is to rotate the leg externally and has a major role in stabilizing the head of the femur into the hip socket.

What causes obturator pain?
Athletes will present with pain, weakness in leg adduction, and sensory loss over a small area in the medial thigh sometimes just with exercise or exacerbated after exercise. Often, obturator neuropathy is caused by pelvic trauma or surgery so athletes should be questioned regarding previous surgery.
How do you release muscle trigger points?
The original way is through trigger point release which involves using a squeeze grip or a tool where direct pressure on the trigger point for 30-120 seconds according to research can release and soften a nodule, once released the muscle tissue needs to be moved throughout its full range of motion, which is why your Jul 7, 2017
Do trigger points release toxins?
Trigger points accumulate inside muscle due to a build up of toxins and a lack of oxygen and blood flow. When applying pressure to the trigger point the toxins break down and blood flow and oxygen and able to flow into that space.
What does the obturator Externus do?
The mechanical model demonstrated that the primary action of the obturator externus muscle was to externally rotate the femur when the hip was in neutral position and flexed at 90°. Its secondary function was as an adductor when the hip was in flexion.
What is the function of obturator?
The internal obturator is situated partly within the lesser pelvis, and partly at the back of the hip-joint. It functions to help laterally rotate femur with hip extension and abduct femur with hip flexion, as well as to steady the femoral head in the acetabulum.
Does trigger point massage release toxins?
When applying pressure to the trigger point the toxins break down and blood flow and oxygen and able to flow into that space. At home you can use a tennis ball, a racket ball, or a golf ball to put pressure on the trigger point to get it to release and dissipate.
What does the obturator nerve control?
The obturator nerve is responsible for the sensory innervation of the skin of the medial aspect of the thigh. The nerve is also responsible for the motor innervation of the adductor muscles of the lower limb (external obturator.
What causes a trigger point in a muscle?
An acute muscle injury or continual muscle stress may lead to the development of trigger points. For example, a spot within or near a strained muscle may become a trigger point. Repetitive motions and poor posture also may increase your risk. Stress and anxiety.
How do you treat trigger points?
Various modalities, such as the Spray and Stretch technique, ultrasonography, manipulative therapy and injection, are used to inactivate trigger points. Trigger-point injection has been shown to be one of the most effective treatment modalities to inactivate trigger points and provide prompt relief of symptoms.
How do you palpate the obturator Internus?
Keep the palpating hand in the position described previously, and gently change the angle of the hand so that the wrist and elbow drops and the fingers move upward into the tissue above. The obturator internus is located in this area. The muscle should feel somewhat soft.
What is the action of obturator Externus?
The obturator externus performs a few different actions. It externally rotates the femur when the hip is extended, but when the hip is flexed it actually abducts the thigh. Together with other short muscles around the hip joint, it contributes to the joint stability.
What is the primary function of the obturator?
The mechanical model demonstrated that the primary action of the obturator externus muscle was to externally rotate the femur when the hip was in neutral position and flexed at 90°. Its secondary function was as an adductor when the hip was in flexion.
