■慢性颈部疼痛(CNP)可导致步态改变,当与头部运动结合时,步态改变会更糟。尚未在患有CNP的老年人中彻底研究用于指示速度和对称性的步态参数。这项研究旨在比较有和没有CNP的老年人在头部运动时在速度和对称性方面的步态表现。
■五十个年轻的老年人,由36名没有颈部疼痛(OLD)的健康对照和14名患有CNP的老年人组成,参与研究。参与者完成了颈部残疾指数和特定活动平衡信心量表。10米步行测试(10MWT)用于评估步态表现。指示参与者在三种不同的头部运动模式下以首选速度行走:无头部运动(NM),水平头部移动(HM),和垂直头部移动(VM)。惯性测量单元用于捕获步态表现,其软件用于分析步态变量;步态速度,运动康复指数(LRI),步态不对称指数,相位协调指数(PCI)。
■CNP组报告了中度颈部疼痛,日常生活活动轻度残疾,平衡信心低于OLD组(p<0.05)。在HM和VM行走过程中,CNP组的步态速度和LRI均显著降低(p<0.05),对应于较低的步幅和节奏。在有VM的步行过程中,CNP组的步态不对称指数明显高于OLD组(p<0.05),而在HM和VM行走期间,PCI明显高于OLD组(p<0.05)。
■慢性颈部疼痛会影响头部运动时的速度和对称性。本研究中的步态参数可用于确定轻度残疾和高身体功能的CNP老年人的步态速度和对称性的变化。
UNASSIGNED: Chronic neck pain (CNP) can lead to altered gait which is worse when combined with head movement. Gait parameters for indicating speed and symmetry have not been thoroughly investigated in older adults with CNP. This study aimed to compare gait performance in term of speed and symmetry in older adults with and without CNP during walking with head movement.
UNASSIGNED: Fifty young older adults, consisting of 36 healthy controls without neck pain (OLDs) and 14 older adults with CNP, participated in the study. Participants completed the Neck Disability Index and Activities-specific Balance Confidence Scale. The 10-Meter Walk Test (10MWT) was used to assess gait performance. Participants were instructed to walk at preferred speed under three different head movement patterns: no head movement (NM), horizontal head movement (HM), and vertical head movement (VM). The Inertial Measurement Unit was used to capture gait performance, and its software was used to analyze gait variables; gait speed, Locomotor Rehabilitation Index (LRI), gait asymmetry index, Phase Coordination Index (PCI).
UNASSIGNED: The CNP group reported moderate neck pain with mild disability in activities of daily living, and less balance confidence than the OLD group (p < 0.05). The CNP group showed significantly slower gait speed and lower LRI during walking with both the HM and VM (p < 0.05), which corresponded to lower stride length and cadence. The gait asymmetry index in the CNP group was significantly higher than the OLD group during walking with VM (p < 0.05), whereas the PCI was significantly higher than the OLD group during walking with both HM and VM (p < 0.05).
UNASSIGNED: Chronic neck pain affects both speed and symmetry when walking with head movement. Gait parameters in this study could be implemented to identify changes in speed and symmetry of gait in older adults with CNP who have mild disability and high physical functioning.
