Purpose[edit | edit source]
The Biering-Sorenson test was first described by Hensen in 1964 as an examination of the isometric endurance of the hip and back extensor muscles. Following a study by Beiring-Sorenson, it was found to be a good assessment tool for predicting the risk of nonspecific lower back pain in patients/clients.
Technique[1][edit | edit source]
To begin this test, an examination plinth, a stopwatch and, three to four straps are needed. The starting position is the patient/client adopting a half prone lying on a plinth with the superior edge of the iliac crest at the edge of the plinth and the arms crossed over the chest. The lower limbs are strategically stabilized with straps. The patient/client is asked to maintains the upper body in a horizontal position and the timer is started. The test ends if the patient/client can maintain the said position for 4minutes(240 seconds) or can no longer maintain the set position before 4minutes elapses. The stop time is recorded.
Evidence[edit | edit source]
There are pieces of evidence to show that this test is an accurate measure of back muscle endurance time and a predictor of the risk of Lowback pain.
