Abstract:Background In AS, the paravertebral muscles can deteriorate due to reduced spinal mobility, leading to muscle atrophy and fatty degeneration.Objective To identify the effects of disease activity on lumbar paraspinal muscles (multifidus, erector spinae) and psoas muscle volume and fatty infiltration in patients with ankylosing spondylitis.Methods The study involved 35 ankylosing spondylitis patients and 25 healthy controls. Pain, disease activity, and functional status were assessed using VAS, BASDAI, and BASFI… Show more
