Comparative Study of Myofascial Exercise and the Voluntary Breathing Technique on the Apnea-Hypopnea Index Among Adolescents.

Background Myofunctional therapy has shown promise in addressing sleep-disordered breathing. This study aimed to investigate the efficacy of myofascial exercise and voluntary breathing techniques in reducing the apnea-hypopnea index (AHI) among adolescents. Methodology In this randomized controlled study, adolescents aged 13-18 with sleep-disordered breathing were randomly assigned to one of three groups (n=40 per group): myofascial exercise, voluntary breathing techniques, and a standard care control group. Baseline assessments, including the AHI and sleep quality, were conducted before the interventions. A polysomnography (PSG) sleep study was performed in a sleep laboratory, with recordings conducted over six to eight hours during the night to calculate the AHI. The myofascial exercise and voluntary breathing technique groups received their respective interventions, while the control group received standard care. Post-intervention assessments were conducted to measure changes in AHI and other outcomes. Results The study found no significant differences in age, BMI, and gender among the three groups. However, significant differences were observed in AHI and sleep quality measures. The control group's AHI was 8.72 ± 1.78, whereas the myofascial exercise group (4.82 ± 1.42) and the voluntary breathing group (6.81 ± 1.83) exhibited more substantial reductions (p < 0.001). Similarly, while baseline sleep quality scores did not differ, significant improvements were observed in all groups post-intervention, with more substantial enhancements in the myofascial exercise (4.38 ± 1.19) and voluntary breathing (7.23 ± 1.76) groups. The analysis of baseline AHI categories revealed no significant differences, but at follow-up, significant variations emerged among the groups, indicating greater reductions in AHI categories in the myofascial exercise and voluntary breathing groups compared to the control group. Conclusion These findings indicate that incorporating myofascial exercises or voluntary breathing techniques into treatment plans for adolescents with sleep-disordered breathing can result in significant improvements in AHI and overall sleep quality.
