Purpose[edit|edit source]
Schober’s test is classically used to determine if there is a decrease in lumbar spine range of motion (flexion), most commonly as a result of ankylosing spondylitis.[1].
The measurement of this test is useful for
- Screening the status ofankylosing spondylitisdisease
- Determination of progression and therapeutic effects of ankylosing spondylitis and other pathologic conditions associated with low back pain[2].
Technique[edit|edit source]
Schöber Test
- Patient is standing, examiner marks the L5 spinous process by drawing a horizontal line across the patients back.
- A second line is marked 10 cm above the first line.
- Patient is then instructed to flex forward as if attempting to touch his/her toes, examiner remeasures distance between two lines with patient fully flexed.
- The difference between the measurements in erect and flexion positions indicates the outcome of the lumbar flexion[1].
Modified Schober Test (eliminates the errors in identification of lumbosacral junction and makes sure that the entire lumbar spine was included[1][3]
- Patient is standing, examiner marks both posterior superior iliac spine (PSIS) and then draws a horizontal line at the centre of both marks
- A second line is marked 5 cm below the first line.
- A third line is marked 10 cm above the first line.
- Patient is then instructed to flex forward as if attempting to touch his/her toes, examiner remeasures distance between the top and bottom line.[1].
Interpretation[edit|edit source]
两个版本的测试,增加更少than 5cm is a positive test and may indicate ankylosing spondylitis (AS). (Image shows region of spine mainly involved in AS)
Positive Schober’s Test
Less than 5cm increase in length with forward flexion: Decreased lumbar spine range of motion, ankylosing spondylitis
Clinical Notes[edit|edit source]
This test is almost exclusively associated with Ankylosing Spondylitis but may also be positive due to a decrease in lumbar range of motion due to pain or congenital anomalies or segmental fusion[4].
Evidence[edit|edit source]
- Original Schöber Test
The validity against radiographs was according to Macrae. strong (r=0.90), according to Rahali-Khachlouf. moderate (r=0.68).
The interclass (r=0.90) and intraclass (r=0.96) reliability was found to be excellent[1]. - Modified Schöber Index
The validity against radiographs was according to Macrae. strong (r=0.97), according to Rahali-Khachlouf. moderate (r=0.59).
The interclass (r=0.92) and intraclass (r=0.96) reliability were found to be excellent[6]. - Modified-modified Schöber Test
