ANALYSIS OF THE EFFECT OF THE DIFFERENCE BETWEEN STANDING AND SITTING POSTURES ON NECK PROPRIOCEPTION USING JOINT POSITION ERROR TEST

The proprioceptive sense is a very important function for the body, and joint position error test (JPET) is commonly used to measure it. This study was to analyze the difference of proprioception in standing and sitting postures through the JPET. A total of 60 students (M/F, 12/48) in D University in Gyeongsangbuk-do, South Korea participated in this study. A JPET was performed with the subject's eyes closed to assess the neck proprioception. The movement of the neck was measured in flexion, extension, and lateral flexion, and separately measured when sitting and standing. The difference in repositioning errors between sitting and standing postures was analyzed using paired t-test. There was a significant difference in repositioning errors between sitting and standing posture in neck extension. There was no significant difference in repositioning errors between sitting and standing posture in neck flexion and lateral flexion. In conclusion, in a sitting posture, posterior neck muscles are used more than in the standing posture, which may negatively affect the proprioceptive accuracy of the neck and may also increase the neck repositioning errors.

Automated summary

This study used JPET to analyze the difference in proprioception between standing and sitting postures in the neck. The results showed a significant difference in repositioning errors during neck extension between sitting and standing postures, but no significant difference during neck flexion and lateral flexion.
