The effects of experience on the inter-reliability of osteopaths to detect changes in posterior superior iliac spine levels using a hidden heel wedge.
Terms Used PSIS reliability, posterior superior iliac spine reliability, PSIS agreement, posterior superior iliac spine agreement; PSIS palpation; posterior superior iliac spine palpation.
The posterior superior iliac spine
was palpated and a small fascial opening was made just lateral to it.
Schantz pins attached to T-handle chucks placed in both posterior superior iliac spines
are used as reduction tools.
Sectioning of the anterior SI ligaments and the sacrospinous ligaments allowed the pelvis to completely open, until the point of bony abutment by the posterior superior iliac spines
Prior to measurements, the skin levels of T1, T12, L5, and posterior superior iliac spines were located by palpation with the subjects standing upright by using the protocol described by Chen et al.
First, the skin levels of T1, T12, L5, and posterior superior iliac spines were palpated and marked when the subjects were standing, and the marks moved upwards during spinal flexion.
(3) Fitt defined neutral alignment as having the ASIS and the posterior superior iliac spines (PSIS) on the same horizontal plane.4 Using either convention, possible misalignments on the sagittal plane are tilting the top of the pelvis too far forward (anterior tilt) or tilting the top of the pelvis too far backward (posterior tilt).
McLain and coworkers (8) placed reflective markers on dancers' anterior superior and posterior superior iliac spines and videotaped them in front of a large grid.
