Standing flexion test is Basically , done for sacroiliac joint dysfunction and sacrum pathology as well.
Any altered mobility, adhesion or decreased ROM of the joint.
Also rule out surrounding ligaments problem as well.
Clinical relevant anatomy ?
The SIJ joint basically connects the sacrum and the ilium bone of the pelvis.
This joint serves a connection between lower extremity and trunk .
Its a strong synovial joint with hyaline and cartilage .
The main anatomy of the sacrum bone is that it performs nutation and counternutaion.
Mainly the Cause of LBP ,that is low back pain is the underlying problem of Sacroiliac joint dysfunction.
Done for diagnosis of pathologies of , lumbar but mainly sacroiliac region.
Its relevancy is quite high and has a good results in clinic.
Purpose of Standing flexion test?
Used to identify any pathology of hip pain, lumbar spine or any sacroiliac joint dysfunction.
The position of flexion of thoracic, lumbar and sacroiliac region causes stress on Sacroiliac joint
And if produces pain ,if there is any underlying pathology .
Standing flexion test can be done for guidance to practitioner , clinicians and further imaging can be done .
Technique for this standing flexion test?
To perform this test, take the patient in standingposition.
Check the alignment of
Ask the patient to flex the thoracic, and then flex the lumbar region .
Then flex the Sacroiliac joint.
While the patient goes down, put your both the thumb on PSIS:- Posterior superior iliac spine .
Then check both the movement of PSIS, while going down .
Also this test is done to rule out the outflare or inflare of joint.
The test would said to be positive if the patient produces pain .
Relevancy of this test?
Little evidence has been found for this test.
So basically, the crux is that research and reports suggested that this test not that much relevant .
To rule out sacroiliac joint dysfunction , other tests like sitting flexion test , Faber test , Gillet test , Rucklauf test.
So all the articles suggested that it is not that much relevant and more further studies are required.
