A Validity Study of Postural Analysis Software Assessment

The misalignment of the vertebra spine affects muscles, tendons and standing posture. Misalignment of the spine provokes the imbalance of shoulders, pelvis and neck posture. The main purpose of this study was to investigate the validity of the digital posture analysis software. 30 college students participated in this study. Posture was evaluated by radiography film and a digital posture analysis program. All the data was collected and statistically analyzed. Measurement of forward head posture appeared 13.39±2.57 mm in postural evaluation software and 16.34±1.94 mm in radiography film. The interclass correlation coefficient between postural analysis software and radiography film is 0.755 (p>0.05). Measurement of shoulder displacement appeared 0.75±0.31° in postural evaluation software and 1.29±0.29° in radiography film. The interclass correlation coefficient between postural analysis software and radiography film is 0.646 (p>0.05). Finally, the measurement of pelvis displacement appeared 0.31±0.34° in postural evaluation software and 0.85±0.38° in radiography film (p>0.05). The interclass correlation coefficient between postural analysis software and radiography film is 0.808. In conclusion, this study suggests the digital posture analysis software is valid for use in the clinic for analyzing a patient’s posture conveniently.
