Spondylolisthesis: Symptoms, Causes & Physical Therapy Treatment
Updated July 20261 minute read
Spondylolisthesis is when one vertebra slips slightly forward over the one below it. Many people have it without symptoms; when it does cause pain, you may feel lower back ache, stiffness, and sometimes leg symptoms, often worse with standing or leaning back. Physical therapy focused on core stability and flexion-friendly movement helps most people manage it well without surgery.
What is spondylolisthesis?
It describes a forward slip of one vertebra on another, usually in the lower lumbar spine. The slip is often mild and stable, and the goal is to control symptoms and build support around the spine.
Symptoms
Common features are lower back pain and stiffness, tight hamstrings, and pain that's often worse with standing, walking, or arching backward and better with sitting or bending forward. A higher-grade slip can cause leg symptoms.
What causes it / risk factors
There are two main types: a stress-related defect in a part of the vertebra (common in active adolescents and certain sports) and an age-related (degenerative) slip. Repetitive extension loading is a risk factor for the first.
How it's diagnosed
Imaging (X-ray, sometimes with flexion/extension views) confirms and grades the slip, interpreted alongside your symptoms.
Physical therapy treatment
What a PT does. Your therapist builds deep core and hip strength to stabilize the segment, favors flexion-friendly movement, and gradually restores activity. Exercises & progression (overview). Core stabilization, glute and hamstring work, and avoiding aggravating extension early on. Stabilization-based PT is well supported. Recovery timeline. Many people improve over 8–12 weeks with consistent training.
Treatment options compared
PT and activity modification are first-line. Bracing may be used in some adolescent cases. Surgery is reserved for high-grade slips or progressive nerve problems.
Red flags
Seek care for progressive leg weakness, groin numbness, or loss of bladder/bowel control.
