Purpose The present study analyses the kinematics of patients with neck problems and healthy controls by estimation of Finite Helical Axis behaviour. A cross sectional study design was used to investigate whether FHA behaviour differs due to neck problems.
584 subjects were recruited from private and ambulatory institutional physiotherapy practices. Among these 171 patients with neck related problems were selected based on referral diagnosis by primary care general practitioners. Cervical kinematics were compared based on minimal convex hull, path length and mean angle of the Finite Helical Axis distribution as well as on the helical angle. Three active planar motions were registered: flexion-extension, axial rotation and lateral bending.
Patients demonstrated a significantly reduced and less variable behaviour of the Finite Helical Axis during active flexion-extension and axial rotation motions as compared to healthy individuals and lateral bending.
Patients with neck related problems demonstrate a more restricted motion behaviour with less variability in Finite Helical Axis distribution and orientation during active planar motions. At present it is not clear whether these kinematic differences are the result or the cause of dysfunction. These slides can be retrieved under Electronic Supplementary Material.
目的 本研究通过估计有限螺旋轴行为来分析颈部问题患者和健康对照者的运动学。采用横断面研究设计来调查有限螺旋轴行为是否因颈部问题而有所不同。
从私立和门诊机构物理治疗实践中招募了584名受试者。其中，根据初级保健全科医生的转诊诊断，选择了171名患有颈部相关问题的患者。基于有限螺旋轴分布的最小凸包、路径长度和平均角度以及螺旋角，对颈椎运动学进行了比较。记录了三种主动平面运动：屈伸、轴向旋转和侧屈。
与健康个体相比，患者在主动屈伸和轴向旋转运动过程中，有限螺旋轴的行为明显减少且变化较小，侧屈时亦是如此。
患有颈部相关问题的患者在主动平面运动过程中表现出更受限的运动行为，有限螺旋轴分布和方向的变化较小。目前尚不清楚这些运动学差异是功能障碍的结果还是原因。这些幻灯片可在电子补充材料中获取。
