Abstract

Purpose
This study compared the subjective and objective sleep quality between subjects with and without thoracic hyper-kyphosis.
Methods
Forty participants were divided into a hyper-kyphosis (n = 17) and normal group (n = 17) by thoracic spinal angle measurement. The subjective sleep quality was measured using PSQI, a self-report, and objective sleep quality was measured using an actigraphy that measures time according to sleep patterns.
Results
The PSQI scores of subjects with thoracic hyper-kyphosis were significantly higher than those with normal thoracic curvature (p = 0.013). The total sleep time and real sleep time were less in subjects with hyper-kyphosis than in normal subjects (p = 0.006;p = 0.029). The light sleep time was less in subjects with excessive spondylolisthesis than in normal subjects (p = 0.010). Light sleep time was less in those with hyper-kyphosis, but deep sleep time was similar to the subjects with a normal thoracic curvature (p = 0.003;p = 0.140).
Conclusion
Subjects with thoracic hyper-kyphosis had a decrease in subjective sleep quality, such as sleep discomfort, and objective sleep quality, such as a decrease in sleep time compared to normal subjects.
