Objective : The purpose of this study was to investigate the effects of wearing an immediate vibration feedback device at the lumbar region on the spine angle in a sitting position.
Design : Cross-sectional study.
Methods : The subjects were 28 healthy university students who were randomized to three interventions. Each condition (A: in a normal chair with an immediate feedback device, B: on the gym ball, C: in a normal chair) spent 10 minutes watching the video, and the order of the experiments was randomized, and the measurements were taken consecutively.
Results : The results showed significant differences in cervical and thoracic angles between conditions and time. Post hoc tests showed no difference at 1 minute, but significant differences at 5 and 10 minutes.
Conclusions : In conclusion, all angles increased over time in all conditions, but the condition of wearing an immediate vibration feedback device with a lower increase was more useful in maintaining spinal angles than the other two conditions. This study suggests that immediate vibration feedback devices may be an alternative to prevent the loss of spinal angle in occupations and environments with prolonged sedentary postures, and further research is needed to investigate the effectiveness of prolonged application.
