Quantitative assessment of head and shoulder posture

Area of Science:

• Biomechanics
• Ergonomics
• Physical Therapy

Background:

• Cervical pain is linked to head, neck, and shoulder posture.
• Current posture assessment is often subjective.
• Objective measurement methods are needed for reliable postural analysis.

Purpose of the Study:

• To determine the reliability of a new objective posture measurement technique.
• To establish normal standards for head and shoulder posture using this technique.
• To evaluate the Postural Analysis Digitizing System (PADS) for clinical use.

Main Methods:

• Utilized the Postural Analysis Digitizing System (PADS), a computer-assisted slide digitizing system.
• Photographed 20 young men in neutral, protracted, and retracted head/shoulder positions.
• Analyzed angular relationships using defined anatomic landmarks and statistical reliability tests.

Main Results:

• The PADS system demonstrated adequate reliability for postural analysis.
• Reproducible measurements were achieved for head and shoulder protraction-retraction.
• Established mean values for various head and shoulder positions.

Conclusions:

• The Postural Analysis Digitizing System (PADS) is a reliable objective tool for measuring head and shoulder posture.
• This technique can aid in the diagnosis and treatment of cervical pain dysfunction syndromes.
• PADS provides a foundation for establishing objective normal standards in postural assessment.
