Sitting in a desk chair all day might not be the sole reason your aging body aches, but for many, extended time at a desk exacerbates existing pain. For instance, a pelvic tilt can cause inflammation in surrounding areas when prolonged pressure from sitting occurs. Fortunately, there is a simple, physical therapist-backed solution for this discomfort.
What Is the Pso-Rite Tool?
The Pso-Rite is a U-shaped plastic tool designed to release the psoas muscle, which runs from the front of each hip into the lower back near the sacrum and lumbar spine. This muscle plays a crucial role in stabilizing the lower back when sitting. When irritated, it can contribute to lower back pain.
Physical therapist Marty Lavine explains that the psoas, combined with the iliacus muscle, forms a large insertion on the femur. This helps create vertical compressive force on the lumbar spine, stabilizing it. However, if the fascial layer covering the muscle becomes restricted, the muscle cannot function correctly, leading to pain. Massaging or releasing these restrictions can provide relief.
How to Use the Pso-Rite
To use the tool, lie face-down and position it so the points of the U sit just above your hip joints. As you settle into place, you may feel a pinch, followed by a slow release as the muscle relaxes. The full effect typically sets in after about a minute and can last for several days.
Lavine notes that if used correctly, the Pso-Rite can penetrate deep enough to help release the ilio-psoas muscle, providing immediate and lasting relief. However, it is essential to consult a medical professional before trying this method, as certain types of pain may require a more holistic approach.
Expert Insights on Long-Term Relief
Physical therapist Jacob VanDenMeerendonk cautions that pain is rarely driven by one isolated muscle. Instead, it is often related to how the spine and hips tolerate load and movement over time. He recommends strength training to build trunk and hip strength while allowing controlled spinal movement for long-term back pain outcomes.
While other physical therapy exercises are instrumental in correcting pelvic tilt and associated lower back pain, the Pso-Rite offers a deeper, more immediate release. It can be used as a quick way to get relief from intense pain, making it possible to perform other exercises that create more permanent fixes.
