Schobers Test
Other Names
- Schober's Test
- Modified Schober's Test
Purpose
- Evaluate lumbar range of motion during flexion
Description
- The patient is standing, examiner behind patient
- Examiner locates lumbosacral junction and marks it with a horizontal line
- A second line is made 10 cm above the first
- Measure the difference between the measurements in erect and flexion positions
- This indicates the degree of lumbar flexion
Modified Test
- Mark S1 spinous process
- Mark 10 cm superiorly
- For ankylosing spondylitis patients, mark 5 cm below as well
- Measure distance between bottom & top lines 15 cm total
- Patient flexes forward with increase in distance 21+ cm
- Positive test
- Shorter increase due to tight musculature or limited lumbopelvic mobility
Pathology
Evidence
- Validity against radiographs is 0.90 [2]
