pain with extension combined with rotation towards the painful side
Wilde et al 2007
localized unilateral LBP
if LBP is caused by minimal perturbations
presence of a step off between adjacent Spinous processes
hypermobility on PPVIM and PAIVM
Paris 1985 ; Nachemson 1985 and Ogon et al 1997
and movements occuring outside the plane of motion like SB or rotation with flexion occurs from a flexed position
No concurrent validity to date
a variation from normal spine coupling
Legaspi & Edmonds 2007
No.
No.
No. The motion is only +/
- inability to stand erect s assistance from hands
Prone instability test: pos test if painful c Lx compression PA at rest but no pain while actively lifting legs. NO VALIDITY.
Radiographs: Axial Compression c wt on shoulders, Axial Traction hanging from a bar.
AP translation: accurate for detection of LSI.
