There is a hypothesis that the growing use of mobile phones in an inappropriate posture to text and read (text neck) could be a reason for the increasing prevalence of neck pain in the past decade. Before testing if there is an association between text neck and neck pain, it is necessary to develop reliable pragmatic tools appropriate to epidemiological studies.
The primary aim of this study was to assess the reliability of the self-perception of text neck, as well as the reliability of physiotherapists' classification of the text neck.
The convenience sample was composed of 113 high school students between 18 and 21 years old from a cross-sectional study. As their self-perceived posture, participants had to choose in a questionnaire one of four neck postures of a person texting on a mobile phone. The physiotherapists classified lateral photographs taken with the participants texting on a mobile phone in their habitual posture as 1 (normal), 2 (acceptable), 3 (inappropriate), and 4 (excessively inappropriate).
The results showed that the test-retest reliability of the self-perception was substantial (kappa = 0.73, 95% CI 0.54 to 0.86). The reliability of the physiotherapists' responses, according to the photographic analysis considering the three raters, was moderate (kappa = 0.5, 95% CI 0.39 to 0.61). Seventy-six percent of the participants with appropriate posture in the photographic analysis self-reported an inappropriate posture.
This study showed that the self-perception of the neck posture during mobile phone texting is reliable over time and that the physiotherapists' classification based on photographic analysis was acceptable for epidemiological studies. Participants had a tendency to report that the posture was worse than it actually was in the photographic analysis performed by the physiotherapists.
有一种假说认为，过去十年间，人们以不适当姿势使用手机发短信和阅读（“短信脖”）的情况日益增多，这可能是颈部疼痛患病率上升的一个原因。在检验“短信脖”与颈部疼痛之间是否存在关联之前，有必要开发适用于流行病学研究的可靠实用工具。
本研究的主要目的是评估对“短信脖”自我认知的可靠性，以及物理治疗师对“短信脖”分类的可靠性。
便利样本来自一项横断面研究中的113名18至21岁的高中生。作为他们对自身姿势的认知，参与者必须在一份问卷中从一张人们用手机发短信的四种颈部姿势图片中选择一种。物理治疗师将参与者以习惯姿势用手机发短信时拍摄的侧面照片分类为1（正常）、2（可接受）、3（不适当）和4（极其不适当）。
结果显示，自我认知的重测信度较高（kappa = 0.73，95%置信区间0.54至0.86）。根据三位评估者的照片分析，物理治疗师反应的信度为中等（kappa = 0.5，95%置信区间0.39至0.61）。在照片分析中姿势合适的参与者中，76%自我报告姿势不合适。
本研究表明，手机短信发送过程中颈部姿势的自我认知随时间推移是可靠的，并且物理治疗师基于照片分析的分类对于流行病学研究是可接受的。在物理治疗师进行的照片分析中，参与者倾向于报告姿势比实际情况更糟。
