Obturator Internus Muscle, Shockwave Therapy & Pudendal Neuralgia

With Chiropractor in Los Gatos, San Jose, SF Bay Area, CA

Pelvic, obturador inernus tendon pain can be helped with Shockwave therapyThe obturator internus muscle can be accessed and treated using focused extracorporeal shockwave therapy (ESWT). Your obturator often goes missed as a perpetrator of hip dysfunction and pelvic pain. ESWT, from the Piezowave, sends low-energy focused shockwaves at pre-prescribed depths into the tendon and even the belly of the obturator interus muscle. This helps alleviate pain in the anterior hip, groin, side of the hip and/or in the low back, as well as a discomfort or pressure sensation deep in the pelvic floor. Seeing that the obturator plays a role in lateral rotation of your femur, abduction of your leg and stabilization of your hip joint, restoring function of the muscle can restore hip mechanics and affect the entire kinetic chain from your ankle to your spine.

Obturator Internus Tendinopathy and ESWT

The tendon of the obturator can develop a tendinopathy. This is when there is either inflammation (tendinitis) or adhesions and degreneration of the tendon (tendinosis). These can develop due to overuse, repetitive strain, or acute injury. Symptoms typically include localized pain at the insertion point on the greater trochanter, which may radiate into the groin or inner thigh. The pain is often aggravated by activities that load the tendon, such as running, jumping, or sudden directional changes. A simple test is to lie prone with your knees bent at 90° and allow your feet to drop laterally as your femur rotates internally. You may notice the limited range of motion on the affected side. Have someone take a photo or a video and you can see the difference in your two legs.

Pelvic, obturador inernus tendon pain can be helped with Shockwave therapyESWT helps obturator internus tendinopathies by sending low-energy focused shockwaves directly into the obturator tendon. Here it can break up brittle adhesions and bring in new blood supply by stimulating angiogenesis. The blood delivers growth factors that promote tissue repair and new collagen fibers that grow into the degenerated obturator tendon. Therefore, this therapy is stimulating tissue regeneration. This seems like a very big claim but there is a lot of research on shockwave therapy and tissue regeneration. Inflammation is allowed to go through the inflammation resolution phase and the risk of re-injury is even decreased. The result is less pain and restored biomechanics in your obturator muscle and hip.

Myofascial Trigger Points in the Obturator Internus Muscle

When the obturator internus muscle develops myofascial trigger points or tendinopathy, it can lead to significant pain and dysfunction. Trigger points are hyperirritable spots in skeletal muscle that can result in referred pain. For the obturator internus, this referred pain is often felt deep within the pelvis, the buttock, or the inner thigh. This can mimic conditions such as sciatica or hip joint pathology and even lead to a misdiagnosis of gynecological, urological, or gastrointestinal conditions. Shockwave therapy has been shown, with before and after MRI studies, to have a beneficial effect at reducing the trigger points. This is especially true for low energy focused shockwave therapy as opposed to a cheaper version called radial shockwave therapy or EPAT. With radial shockwaves, there is a different waveform that is concentrated on the skin rather than the targeted area. The result can be bruising or even scabbing in the area and a destruction of underlying tissues. This is way too delicate of an area to trust it to radial shockwave.

Obturator Internus Muscle and Pudendal Neuralgia

The obturator internus muscle plays a significant role in the context of pudendal neuralgia due to its anatomical relationship with the pudendal nerve. When it becomes tense, tight, or spasmodic, it can exert pressure on the pudendal nerve, especially as the nerve passes through the Alcocks or pudendal canal. When the tendinopathy, the spasms and the trigger points are alleviated the pudendal neuralgia.

Clinical Evidence and Outcomes

Numerous studies have demonstrated the efficacy of ESWT in treating tendinopathies and myofascial pain syndromes. Patients often report significant pain relief and improved function after a series of ESWT sessions. The non-invasive nature of the treatment, combined with its ability to target deep tissues, makes it an attractive option for conditions like obturator internus dysfunction.

Conclusion

The obturator internus muscle plays a crucial role in hip stability and movement. When it develops trigger points or tendinopathy, it can cause significant pain and dysfunction. ESWT offers a promising treatment option for these conditions, providing pain relief and promoting tissue healing without the need for invasive procedures. By addressing the underlying pathology, ESWT can help restore normal function and improve the quality of life for patients suffering from obturator internus-related pain.

Note that obturator internus issues can be associated with piriformis syndrome and greater trochanteric pain syndrome or hip bursitis and these will be analyzed for during your initial exam.
