Introduction: This study aimed to investigate the relationship between childbirth and lower back pain and determine the health-related quality of life of female patients with lower back pain.

Methods: A total of 111 patients were divided into three groups: those who had given birth and developed lower back pain due to pregnancy, childbirth, or child-rearing movements (childbirth group, n=41), those who had given birth and developed lower back pain due to other causes (childbirth and other cause group, n=29), and those who were nulliparous (nulliparous group, n=41). A total of 22 physical therapists evaluated the patients during initial rehabilitation.

Introduction: Several measurement methods designed to provide an understanding of cervical sagittal alignment have been reported, but few studies have compared the reliabilities of these measurement methods. The purpose of the present study was to investigate the intraexaminer and interexaminer reliabilities of several cervical sagittal alignment measurement methods and of the rotated cervical spine using plain lateral cervical spine X-rays of patients with cervical spine disorders.

Methods: Five different measurement methods (Borden's method; Ishihara index method (Ishihara method); C2-7 Cobb method (C2-7 Cobb); posterior tangent method: absolute rotation angle C2-7 (ARA); and classification of cervical spine alignment (CCSA)) were applied by seven examiners to plain lateral cervical spine X-rays of 20 patients (10 randomly extracted cases from a rotated cervical spine group and 10 from a nonrotated group) with cervical spine disorders.
