The Quadratus Lumborum (QL) is a deep muscle in the lower back that helps stabilise the spine and pelvis during movement. When it becomes tight or overloaded, it can contribute to stiffness, one-sided lower back pain and difficulty with everyday activities.
Common Symptoms
- One-sided lower back ache or tightness
- Pain when standing up after sitting
- Discomfort rolling in bed
- Tightness with side bending or walking
- Referral into the buttock or top of the hip
Why Does It Become Tight?
- Prolonged sitting
- Poor posture or workstation setup
- Repetitive lifting
- Hip or glute weakness
- Sporting overload
- Previous back injuries
How Can Trigger Point Release Help?
- Reduce muscle tension and guarding
- Improve lower back mobility
- Improve comfort with sitting, standing and walking
- Support exercise and rehabilitation programs
The Bigger Picture
The QL is often working overtime because another part of the body isn’t doing its job effectively. While hands-on treatment can help reduce symptoms, long-term improvement usually comes from combining treatment with strengthening, mobility work and load management. If persistent lower back tightness or stiffness is affecting your daily life, speak to your Osteopath about whether the QL may be contributing to your symptoms.
