This study evaluated the criterion-related validity of the Electronic Head Posture Instrument (EHPI) in measuring the craniovertebral (CV) angle by correlating the measurements of CV angle with anterior head translation (AHT) in lateral cervical radiographs. It also investigated the correlation of AHT and CV angle with the Chinese version of the Northwick Park Questionnaire (NPQ) and Numeric Pain Rating Scale (NPRS). Thirty patients with diagnosis of mechanical neck pain for at least 3 months without referred symptoms were recruited in an outpatient physiotherapy clinic. The results showed that AHT measured with X-ray correlated negatively with CV angle measured with EHPI (r = -0.71, p < 0.001). CV angle also correlated negatively with NPQ (r = -0.67, p < 0.001) and NPRS (r = -0.70, p < 0.001), while AHT positively correlated with NPQ (r = 0.390, p = 0.033) and NPRS (r = 0.49, p = 0.006). We found a negative correlation between CV angle measured with the EHPI and AHT measured with the X-ray lateral film as well as with NPQ and NPRS in patients with chronic mechanical neck pain. EHPI is a valid tool in clinically assessing and evaluating cervical posture of patients with chronic mechanical neck pain.
本研究通过将颈椎侧位X线片上的颅椎（CV）角测量值与头部前伸（AHT）进行相关性分析，评估了电子头部姿势测量仪（EHPI）在测量CV角方面的效标关联效度。本研究还调查了AHT和CV角与中文版诺斯威克公园问卷（NPQ）及数字疼痛评分量表（NPRS）之间的相关性。在一家门诊物理治疗诊所招募了30例诊断为机械性颈痛至少3个月且无牵涉痛症状的患者。结果显示，X线测量的AHT与EHPI测量的CV角呈负相关（r = -0.71，p < 0.001）。CV角也与NPQ呈负相关（r = -0.67，p < 0.001）以及与NPRS呈负相关（r = -0.70，p < 0.001），而AHT与NPQ呈正相关（r = 0.390，p = 0.033）以及与NPRS呈正相关（r = 0.49，p = 0.006）。我们发现，在慢性机械性颈痛患者中，EHPI测量的CV角与X线侧位片测量的AHT以及与NPQ和NPRS之间均呈负相关。EHPI是临床上评估和评价慢性机械性颈痛患者颈椎姿势的有效工具。
