What Causes Mechanical Low Back Pain?
Low back pain is one of the most common reasons people visit an osteopath. When it isn't linked to a serious underlying disease or nerve compression, it's often called mechanical low back pain, meaning the pain arises from the way muscles, joint, discs and ligaments of the spine move and interact, and this accounts for 90-95% of all cases of low back pain.
What Does Mechanical Mean?
This refers to pain that is associated with movement, posture or load rather than disease or infection. It typically worsens with certain positions or activities, and eases with rest and heat. This form of back pain can stem from how the spine is used day-to-day, such as sitting for long periods, repetitive bending, lifting or poor ergonomic habits.
Common Structures Involved

Facet joints: small joints between the vertebrae that can become stiff or irritated.
Intervertebral discs: the cushions between bones that may develop strain or small tears without necessarily causing a herniation
Muscles and fascia: tension, spasm or fatigue due to awkward postures or repetitive overuse.
Ligaments: overstretching or sprains can cause ligaments to become painful.
Typical Triggers
Long periods of sitting or standing
Lifting or twisting repetitively
Sudden increases in physical activity
Weakness or poor endurance of spinal muscles
Stress, poor sleep and fatigue which can raise muscle tension
How Osteopathy Can Help
An osteopath assesses the entire body to identify muscle imbalances, joint restriction and muscle tension that may contribute to low back pain.
Treatment may include:
Hands-on techniques to improve mobility and reduce tension
Dry needling
Manipulation
Targeted exercises for strength and flexibility
Postural and ergonomic advice
Education to help you understand your condition and self-manage effectively
Bottom Line
90-95% of cases of low back pain results from how the spine and its supporting tissues move and are loaded - it is not related to structural damage. With early movement and treatment, most people can recover well.
