On basis of 3 Tesla magnetic resonance imaging, angles and spatial relations were compared at the lumbar spine. ASIS = anterior superior iliac spine, ax = axial plane, co = coronal plane, cd = caudal, cr = cranial, d = dorsal, l = left, MRI = magnetic resonance imaging, PSIS = posterior superior iliac spine, r = right, S 1,2,etc. = first (second, etc.) sacral vertebral body, sa = sagittal plane, Th 12 = twelfth thoracic vertebral body, v = ventral, ∡ = angle.

On basis of 3 Tesla magnetic resonance imaging, angles and spatial relations were compared at the pelvis. ASIS = anterior superior iliac spine, ax = axial plane, co = coronal plane, cd = caudal, cr = cranial, d = dorsal, l = left, MRI = magnetic resonance imaging, PSIS = posterior superior iliac spine, r = right, S 1,2,etc. = first (second, etc.) sacral vertebral body, sa = sagittal plane, Th 12 = twelfth thoracic vertebral body, v = ventral, ∡ = angle.

On basis of 3 Tesla magnetic resonance imaging, angles and spatial relations were compared at the sacroiliac joint. ASIS = anterior superior iliac spine, ax = axial plane, co = coronal plane, cd = caudal, cr = cranial, d = dorsal, l = left, MRI = magnetic resonance imaging, PSIS = posterior superior iliac spine, r = right, S 1,2,etc. = first (second, etc.) sacral vertebral body, sa = sagittal plane, Th 12 = twelfth thoracic vertebral body, v = ventral, ∡ = angle

A SacroLoc belt (Bauerfeind AG, Zeulenroda-Triebes, Germany) is applied to a female volunteer under moderate tension, as recommended by the manufacturer.

Baseline data of SIJ patients.
Fig 6.
11-point Numerical rating scale (NRS) data on pain intensity.
Fig. 6A: Non-significantly altered pain intensity was observed in sacroiliac joint pain patients with belt application under moderate tension, while maximum tension slightly increased pain intensity. Fig. 6B: Comparison to the condition without pelvic belt (Δ NRS) revealed that moderate tension tended to change pain intensity more effectively than maximum tension in patients with sacroiliac joint pain on a non-significant level.
