Measurement of craniovertebral angle with Electronic Head Posture Instrument: Criterion validity

Herman Mun Cheung Lau, PgD, MPhil, et al.


Figure 2. Reading from SmartTool Angle Finder represents craniovertebral angle when two indicator lines were aligned with pin markers (seventhcervical [C7] vertebra spinous process) and tragus.

Traditionally, clinicians assess head-neck posture using radiography and sophisticated equipment. The Electronic Head Posture Instrument (EHPI) is a simple and convenient device developed to help clinicians measure the head-neck posture of patients with long-term mechanical neck pain. In this study, we evaluated the accuracy and usefulness of the EHPI and investigated the relationship between subjective pain intensity, head-neck posture, and disability by means of a questionnaire. The results showed that the instrument is useful for clinicians to assess patients with long-term mechanical neck pain and that poor head-neck posture is positively related to neck disability and pain intensity.
