The Psoas Muscle and Lower Back Pain: Unveiling the Connection Through Latest Research


Lower back pain can be incredibly debilitating, affecting individuals of all ages and backgrounds. While there are multiple factors contributing to lower back pain, recent medical research has shed light on the significance of the psoas muscle in this condition. Understanding the importance of this muscle and its relationship with lower back pain enables us to explore effective strategies for prevention and management. This blog post delves into the latest research on the psoas muscle and how it plays a crucial role in lower back pain.

The Psoas Muscle:

The psoas muscle is a deep-seated muscle located in the lower part of the spine and stretches through the pelvis down into the thighs. It is one of the primary muscles involved in hip flexion and the initiation of walking or running movements. Moreover, the psoas muscle plays a critical role in stabilizing the spine, transferring forces between the upper and lower body, and maintaining proper posture.

Psoas Muscle Dysfunction and Lower Back Pain:

Recent research has highlighted how dysfunctional psoas muscles can contribute significantly to lower back pain. A study published in the Journal of Back and Musculoskeletal Rehabilitation found that a hypertonic (overly tensed) psoas muscle can compress the lumbar vertebrae, leading to excessive strain on the discs and joints in the lower back. This increased strain can eventually result in inflammation, muscle imbalances, and overall lower back pain.

Another study published in the International Journal of Therapeutic Massage and Bodywork concluded that individuals with chronic lower back pain displayed a greater occurance of shortened and weak psoas muscles. Weakness in the psoas muscle can lead to poor stabilisation of the lumbar spine and increased stress on the surrounding structures, exacerbating lower back pain.

The Role of Psoas Strengthening and Stretching:

Strengthening and stretching exercises targeting the psoas muscle have demonstrated promising results in relieving lower back pain and preventing its recurrence. A systematic review published in the Journal of Physical Therapy Science found that targeted exercise programs addressing the psoas muscle's strength and length effectively reduced lower back pain and improved functional outcomes.

Engaging in exercises such as psoas stretches, leg lifts, lunges, and core stabilization exercises, under proper guidance, can alleviate tension in the psoas muscle and help restore its normal length and strength. These exercises not only improve the flexibility and stability of the lower back but also promote overall postural alignment.


The psoas muscle's significance in relation to lower back pain cannot be overlooked based on the latest research findings. Recognising the role of the psoas muscle in stabilizing and supporting the lower back can aid in a deeper understanding of the condition and assist in the implementation of appropriate preventative measures and treatment strategies. Incorporating targeted exercises, alongside professional guidance, enables individuals to effectively manage lower back pain and improve their overall well-being. Remember, a strong and balanced psoas muscle can contribute significantly to a healthier and pain-free lower back. Our treatment programs are designed specifically with this in mind. Ensuring that the appropriate exercises are given to you in the right order, to ensure optimal healing and enabling you to return to the activities you love.
