在主动前屈期间异常运动模式的临床观察是用于识别怀疑有运动协调障碍的非特异性腰痛患者的一个标准。本研究的目的是使用动力学系统方法描述和量化骨盆和躯干的运动学模式，并确定临床观察和运动学分类之间的一致性。98名受试者进行重复前屈，同时收集临床观察和运动学数据。使用角-角、耦合角和相平面图绘制运动学数据。准确度统计结合受试者工作特征曲线用于确定临床观察和运动学模式之间的一致性。运动模式与临床观察结果一致，典型和异常运动模式的定义具有中度一致性（kappa = 0.46-0.50; PABAK = 0.49-0.73）。在前38%的运动中，腰盆耦合角图中的早期骨盆运动优势≥59°，代表观察到的腰盆节律改变。腰椎速度频繁中断（由相平面图表示，局部最小值发生率≥6）和腰椎骨盆耦合角图中突然解耦（局部最小值和最大值发生率之和≥15）代表观察到的震颤。这些发现进一步定义了骨盆和腰椎之间的运动协调性的观察改变腰骨盆节律和颤抖的存在。腰椎节段的运动质量是识别抖动的关键。这些信息将帮助临床医生更好地了解和识别非特异性腰痛患者的异常运动模式。
Clinical observation of aberrant movement patterns during active forward bending is one criterion used to identify patients with non-specific low back pain suspected to have movement coordination impairment. The purpose of this study was to describe and quantify kinematic patterns of the pelvis and trunk using a dynamics systems approach, and determine agreement between clinical observation and kinematic classification. Ninety-eight subjects performed repeated forward bending with clinical observation and kinematic data simultaneously collected. Kinematic data were plotted using angle-angle, coupling-angle, and phase-plane diagrams. Accuracy statistics in conjunction with receiver operating characteristic curves were used to determine agreement between clinical observation and kinematic patterns. Kinematic patterns were consistent with clinical observation and definitions of typical and aberrant movement patterns with moderate agreement (kappa = 0.46–0.50; PABAK = 0.49–0.73). Early pelvic motion dominance in lumbopelvic coupling-angle diagram ≥59° within the first 38% of the movement represent observed altered lumbopelvic rhythm. Frequent disruptions in lumbar spine velocity represented by phase-plane diagrams with local minimum occurrences ≥6 and sudden decoupling in lumbopelvic coupling-angle diagrams with sum of local minimum and maximum occurrences ≥15 represent observed judder. These findings further define observations of movement coordination between the pelvis and lumbar spine for the presence of altered lumbopelvic rhythm and judder. Movement quality of the lumbar spine segment is key to identifying judder. This information will help clinicians better understand and identify aberrant movement patterns in patients with non-specific low back pain.
