Ankylosing spondylitis (AS) is a chronic, inflammatory rheumatic disease. The spine becomes rigid from the occiput to the
sacrum, leading to a stooped position. This study aims at evaluating AS subjects gait alterations. Twenty-four subjects were
evaluated: 12 normal and 12 pathologic in stabilized anti-TNF-alpha treatment (mean age 49.42 (10.47), 25.44 (3.19) and mean
body mass index 55.75 (3.19), 23.73 (2.7), respectively). Physical examination and gait analysis were performed. A motion
capture system synchronized with two force plates was used. Three-dimensional kinematics and kinetics of trunk, pelvis, hip,
knee and ankle were determined during gait. A trend towards reduction was found in gait velocity and stride length. Gait analysis
results showed statistically significant alterations in the sagittal plane at each joint for AS patients (P < 0.049). Hip and knee joint extension moments showed a statistically significant reduction (P < 0.044). At the ankle joint, a decreased plantarflexion was assessed (P < 0.048) together with the absence of the heel rocker. Gait analysis, through gait alterations identification, allowed planning-specific
rehabilitation intervention aimed to prevent patients’ stiffness together with improve balance and avoid muscles’ fatigue. 相似文献
