 - Background
This study aimed to examine the changes in height, weight, and bone age between pre- and post-intervention when using a BEG-100 massage chair daily.
Methods
Thirty-five children aged 11 years who were close to the average height (145-155 cm) were included in the study. There were 34 participants who used the BEG-100 massage chair for 24 weeks. Daily intervention consisted of 20 minutes of lower body massage and 10 minutes of whole-body massage. Height, weight, and adverse events were checked every five visits, while a hand X-ray was used before and after massages. The height percentile and height standard deviation score (SDS) were calculated using the 2017 Korean growth chart. The bone age and predicted adult height using radiographs were computed using the Tanner-Whitehouse method. The paired t-test or Wilcoxon signed-rank test was used according to normality of data to determine statistical significance.
Results
A total of 31 children were included in the final analysis. The height percentile and height SDS significantly increased after BEG-100 massage chair use (2.39; p = 0.032, and 0.07; p = 0.036, respectively). However, these changes were not significant in children whose baseline height was shorter than the average. There were no significant differences in bone age, height for bone age, predicted adult height, or sitting height/height ratio. None of the participants complained of adverse events.
Conclusion
The height percentile and SDS of teenagers increased after use of massage chair therefore, it is necessary to perform larger randomized controlled clinical studies. Trial registration: KCT0004673.
