The aim of this study was to establish whether there is a relationship between conditions of accommodative visual dysfunctions and cervical complaints. Fifty-two participants were included. Variables were accommodative amplitude, positive and negative relative accommodation (NRA), accommodative response, and accommodative facility. Subjects were classified as accommodative insufficiency, accommodative excess, or normal. Neck complaints were measured with the Neck Disability Index, the Visual Analogue Scale, and by cervical range of motion, deep flexor muscle activation score, and performance index. We found the following significant relationships: between NRA and both performance index and left-side bending; accommodative amplitude right-eye with right-side bending and with left-side bending; accommodative amplitude left-eye with right-side bending; and accommodative facility left-eye with both performance index and left-side bending. In accommodative amplitude right-eye, aIl participants showed significant values and greater than those with accommodative excess. In both groups, performance index values were decreased. Greater pain and lower right-rotation were found in participants with accommodative excess than in those with accommodative insufficiency. We conclude that accommodative dysfunctions are related to low performance index, decreased range of motion, as well as greater neck pain.
本研究旨在确定调节性视觉功能障碍与颈部不适之间是否存在关联。共纳入 52 名参与者。研究变量包括调节幅度、正相对调节（NRA）和负相对调节（NRA）、调节反应和调节灵活度。参与者被分为调节不足、调节过度和正常三组。颈部不适通过颈部残疾指数（NDI）、视觉模拟评分（VAS）、颈椎活动度、深层屈肌激活评分（DFMAS）和表现指数（PI）进行评估。我们发现以下显著关系：NRA 与 PI 和左侧弯曲、右眼调节幅度与右侧弯曲和左侧弯曲、左眼调节幅度与右侧弯曲、左眼调节灵活度与 PI 和左侧弯曲均存在显著关系。右眼调节幅度的所有参与者的数值均显著且大于调节过度组。两组的 PI 值均降低。与调节不足组相比，调节过度组的疼痛更严重，右侧旋转范围更小。我们得出结论，调节功能障碍与低 PI 值、活动度降低以及更严重的颈部疼痛有关。
