The measurement of craniocervical posture: a simple method to evaluate head position

Area of Science:

• Orthodontics
• Radiology
• Pediatric Dentistry

Background:

• Craniocervical posture (CCP) is linked to various health issues, including breathing problems and pain.
• Accurate measurement of head position is crucial for studying CCP.
• Existing methods often involve radiation or specialized equipment like cephalostats.

Purpose of the Study:

• To introduce a novel method for measuring natural head position (NHP) without radiation or cephalostat fixation.
• To assess the reproducibility of this NHP measurement method when positioning subjects for lateral cephalograms.

Main Methods:

• Fifty healthy children (mean age 10.9 years) participated.
• A non-radiation-based technique was used to capture natural head position (NHP) using cutaneous markers and digital imaging.
• The method involved standardizing foot position, head tilting to achieve balance, and shoulder posture.
• The reproducibility of NHP was tested by repositioning subjects in a cephalostat and comparing images.

Main Results:

• No statistically significant differences were found in head position measurements (N-Tr-Vert, C(7)-Tr-Vert, C(7)-Tr-N) between initial NHP capture and subsequent cephalostat positioning.
• The results indicate high precision and stability in the measurements.

Conclusions:

• The developed method is effective for evaluating head posture without radiation exposure.
• This technique offers a simple, rapid way to position patients for radiographs, preserving their natural head position (NHP).
• It facilitates accurate craniocervical posture (CCP) studies.
