Abstract

Objective

The primary objective of the present study was to examine the differences and patterns of change in the neck extensor (NE) muscle stiffness during the Cranio-cervical flexion (CCF) task under different functional conditions of the upper extremity between CNSNP participants and asymptomatic controls.

Methods

In the current case-control study, 25 participants with CNSNP and 25 asymptomatic controls were recruited. The stiffness of the superficial (i.e., upper trapezius, splenius capitis, and semispinalis capitis) and deep (i.e., semispinalis cervicis and multifidus) NE muscles was measured at prone resting, sitting resting, and during the CCF task in different functional conditions of upper extremity using shear wave elastography.

Results

The findings showed that there was a significant main effect of condition in all NE muscles (P < 0.05), as well as a significant main effect of the group on the stiffness of superficial neck muscles (P < 0.05), indicating higher muscle stiffness in participants with CNSNP compared to the control group. There was no significant group-by-condition interaction effect on the stiffness of NE muscles (P > 0.05), except for the upper trapezius muscle (P = 0.00), indicating a different pattern of stiffness changes compared to the other muscles.

Conclusions

Individuals with CNSNP exhibited significantly greater stiffness in the superficial neck extensor muscles compared to healthy controls. Furthermore, the CCF task performed under functional upper extremity conditions, which includes bilateral shoulder scaption and shoulder abduction-external rotation while seated, resulted in increased stiffness of the NE muscles. Additionally, participants with CNSNP exhibited a higher magnitude of stiffness changes in the upper trapezius muscle across different conditions.

慢性非特异性颈部疼痛患者在上肢功能条件下屈曲颅颈时颈部肌肉僵硬：剪切波弹性成像研究

目的本研究的主要目的是探讨在颅颈屈曲（CCF）任务中，在上肢不同功能条件下，CNSNP 患者与无症状对照组之间颈部伸肌（NE）僵硬度的差异和变化规律。方法在本病例对照研究中，招募了 25 名 CNSNP 患者和 25 名无症状对照组。表层（即斜方肌上部、脾岬肌和半脊柱岬肌）和深层（即颈椎半脊柱肌）肌肉的僵硬度分别为 0.5%、0.5% 和 0.5%、结果表明，所有东北东北肌肉的僵硬度均存在显著的主条件效应（P < 0.05），颈部浅层肌肉的僵硬度也存在显著的组间主条件效应（P < 0.05），这表明与对照组相比，中枢神经系统营养不良患者的肌肉僵硬度更高。结论与健康对照组相比，CNSNP 患者颈部浅层伸肌的僵硬度明显更高。此外，在功能性上肢条件下进行的 CCF 任务（包括坐位时的双侧肩胛和肩外展-外旋）会导致东北神经肌肉的僵硬度增加。此外，在不同条件下，CNSNP 患者的斜方肌上部的僵硬度变化幅度更大。
