Abnormal postures of the trunk are a typical feature of @entity191 ( @entity191 ). These include @entity751 ( @entity751 ), a tonic lateral flexion of the trunk associated with slight rotation along the sagittal plane. In this study we describe clinical, electromyographic (EMG), and radiological features of @entity751 in a group of 20 @entity191 @entity1 . All @entity1 with trunk deviation underwent EMG and radiological (RX and CT scan) investigation. Clinical characteristics of @entity1 with @entity751 were compared with a control group of @entity191 @entity1 without trunk deviation. @entity191 @entity1 with @entity751 showed a significantly higher score of disease asymmetry compared with the control group. In the majority of @entity1 with @entity751 , trunk bending was contralateral to the side of symptom onset. EMG showed abnormal tonic @entity2915 on the side of the deviation in the paravertebral thoracic muscles and in the abdominal oblique muscles. CT of the lumbar paraspinal muscles showed @entity2057 more marked on the side of the deviation, with a craniocaudal gradient. @entity751 may represent a complication of advanced @entity191 in a subgroup of @entity1 who show more marked asymmetry of disease and who have detectable @entity2915 of the dorsal paravertebral muscles on the less affected side. This postural abnormality deserves attention and proper early treatment to prevent comorbidities and @entity158 .
