To investigate the association between trunk muscle endurance, standing balance, and neck disability in women with chronic neck pain (CNP) and to compare trunk muscle endurance and standing balance according to disability severity.
Thirty-one women with CNP and Neck Disability Index scores of 30%-70% were included. Isometric endurance times of neck flexors, trunk flexors, extensors, and lateral flexors were measured. Overall stability index (OSI), anterior/posterior stability index (APSI), and medial/lateral stability index (MLSI) were obtained to assess standing balance under the following conditions: eyes-open on a firm surface (EO-Firm), eyes-closed on a firm surface, eyes-open on foam, and eyes-closed on foam (EC-Foam). Higher index scores indicate larger postural sway. Linear regression analysis was used for association. Participants were divided into two groups based on their disability scores, either having moderate or severe disability, and the groups were compared.
Trunk flexor endurance time had an effect on disability (R-squared=0.18, F(1.29)=6.453) and APSI under the EC-Foam condition (R-squared=0.17, F(1.29)=6.105) (p<0.05). Trunk extensor endurance time had an effect on OSI under the EO-Firm condition (R-squared=0.14, F(1.29)=4.775, p<0.05). Women with moderate disability had longer endurance times than those with severe disability for trunk flexors (Cohen's d=0.89, p<0.05).
Isometric endurance times of trunk flexors and extensors were associated with standing balance in women with CNP. Trunk flexor endurance was also associated with neck disability. Furthermore, women with moderate disability had better trunk flexor endurance than those with severe disability, with a large effect size.
探讨慢性颈痛（CNP）女性躯干肌肉耐力、站立平衡与颈部残疾之间的关系，并根据残疾严重程度比较躯干肌肉耐力和站立平衡。
纳入 31 名 CNP 且 Neck Disability Index 评分为 30%-70%的女性。测量颈屈肌、躯干屈肌、伸肌和侧屈肌的等长耐力时间。在以下条件下评估站立平衡的整体稳定性指数（OSI）、前/后稳定性指数（APSI）和内/外稳定性指数（MLSI）：睁眼在硬表面（EO-Firm）、闭眼在硬表面、睁眼在泡沫上、闭眼在泡沫上（EC-Foam）。指数得分越高表示姿势摆动越大。采用线性回归分析进行关联。根据残疾评分将参与者分为中度或重度残疾两组，并进行比较。
躯干屈肌耐力时间对残疾（R-squared=0.18，F(1.29)=6.453）和 EC-Foam 条件下 APSI（R-squared=0.17，F(1.29)=6.105）有影响（p<0.05）。躯干伸肌耐力时间对 EO-Firm 条件下 OSI 有影响（R-squared=0.14，F(1.29)=4.775，p<0.05）。中度残疾的女性比重度残疾的女性躯干屈肌耐力时间更长（Cohen's d=0.89，p<0.05）。
CNP 女性躯干屈肌和伸肌的等长耐力时间与站立平衡有关。躯干屈肌耐力也与颈部残疾有关。此外，中度残疾的女性躯干屈肌耐力比重度残疾的女性更好，具有较大的效应量。
