Background

Most studies suggest that people with chronic neck pain (CNP) have decreased balance abilities. However, balance performance during performing concurrent tasks is not clarified.

Objectives

To investigate balance performance under different sensory and dual-task conditions in people with and without CNP.

Method

Twenty-two women with CNP and twenty-two asymptomatic women were tested using the Biodex Stability System. Overall stability index (OSI), anterior/posterior stability index (APSI), medial/lateral stability index (MLSI) were obtained in two sessions: eyes-open and eyes-closed. Both sessions consisted of four conditions: quiet standing, rotating head, counting backward, standing on foam. Higher index scores mean poorer balance.

Design

Case-Control study.

Results

A mixed factorial ANOVA (2 × 8 design) showed that there was a main effect of CNP on OSI, APSI, and MLSI (p < 0.001), which indicates that CNP causes poor balance. Further, there was an interaction between CNP and test conditions for only OSI (p < 0.05). Simple effects tests showed that patients with CNP had higher OSI in all conditions except standing on foam with eyes-open, and quiet standing and counting backward with eyes-closed (p < 0.05). The largest effect size was obtained during rotating head with eyes-open (η2:0.301), followed by counting backward with eyes-open and quiet standing with eyes-open (η2:0.267 and 0.245). Performing a concurrent task, closing eyes, or standing on foam mostly increased OSI in both groups (p < 0.05).

Conclusions

Patients with CNP have poorer balance under different sensory and dual-task conditions. Addressing balance assessment while performing concurrent tasks, especially head rotations, may offer new insights into the management of CNP.

慢性颈痛患者不同感觉和双任务条件下平衡能力的研究

背景

大多数研究表明,患有慢性颈部疼痛 (CNP) 的人平衡能力下降。但是,在执行并发任务期间的平衡性能没有明确。

目标

调查有和没有 CNP 的人在不同感官和双任务条件下的平衡表现。

方法

使用 Biodex Stability System 测试了 22 名患有 CNP 的女性和 22 名无症状的女性。总体稳定性指数(OSI)、前/后稳定性指数(APSI)、内侧/外侧稳定性指数(MLSI)分两个时段获得:睁眼和闭眼。两次会议都包括四个条件:安静站立、转动头部、倒数数、站在泡沫上。较高的指数分数意味着较差的平衡。

设计

病例对照研究。

结果

混合因子方差分析(2 × 8 设计)显示 CNP 对 OSI、APSI 和 MLSI 有主要影响(p < 0.001),这表明 CNP 导致平衡不良。此外,CNP 与仅 OSI 的测试条件之间存在相互作用(p < 0.05)。简单的效应测试表明,CNP 患者在所有情况下都有更高的 OSI,除了睁眼站在泡沫上,安静地站立并闭眼向后计数(p < 0.05)。在睁眼旋转头部时获得最大的效应量 (η 2 :0.301),其次是睁眼向后计数和睁眼安静站立时 (η 2 :0.267 和 0.245)。执行并发任务、闭眼或站在泡沫上大多会增加两组的 OSI(p < 0.05)。

结论

CNP 患者在不同的感觉和双重任务条件下平衡能力较差。在执行并发任务时进行平衡评估,尤其是头部旋转,可能会为 CNP 的管理提供新的见解。
