About

  1. Background: In modern society, people are spending more time sitting due to the increased use of IT devices. Prolonged sitting with incorrect posture can lead to spinal deformities and an increase in spinal diseases. Common deformities include turtle neck posture, flat back, straight neck, and bent back. Misalignment of the spine is considered an important factor in causing spinal diseases, such as pain, arthritis, and degeneration. To address these issues, researchers have developed pillows and chairs that are ergonomically designed for everyday use and have been found to be effective.
  2. Purpose: This study aims to investigate whether portable equipment can help individuals recognize and maintain correct sitting posture on their own.
  3. Design: This study has a cross-sectional study design. Each condition is divided into three different sitting conditions. By using post-evaluation data, the intention is to compare the effects. (Condition A: sitting on a standard chair wearing an immediately feedback device, Condition B: sitting on a gym-ball, Condition C: sitting on standard chair)
  4. Subject : Twenty-eight subjects were recruited as healthy students attending S University located in Nowon-gu, Seoul.
  5. Result: The study found that maintaining a sitting posture immediately resulted in a statistically significant lower angle over time at the Cervicothoracic angle compared to other interventions. Similarly, a sitting posture immediately maintained a lower angle over time at the Thoracic angle compared to other sitting postures . However, the lumbar angle showed a significant increase over time.
