    The systematic review and meta-analysis by Abdullah ALQarni et al. on the effect of positional vibrotactile therapy for positional obstructive sleep apnoea shows that this treatment modality is effective, reducing time in the supine position, severity of obstructive sleep apnoea and daytime sleepiness. (1) It also highlights the lack of patient-centered outcomes beyond daytime sleepiness, which is very important to achieve good adherence to treatment, one of the main limitations of obstructive sleep apnoea treatment to achieve greater health benefits for patients as shown by different clinical trials that have failed to show significant results of continuous airway pressure (CPAP) in the prevention of cardiovascular events in intention-to-treat analyses but did show significant results in patients with good adherence to treatment (2).
    Based on this statement, we would like to refer you to our last publication (3), a RCT, which shows high good compliance rates for the active device (mean value of 85% ± 36.6%, defined as device use for more than 4 hours per night and more than 70% of nights per week), values above the usual ones for CPAP treatment, (generally 40%–50% in the long term)(4,5), from the first day and sustained form over time. Patient ́s satisfaction was high and minor side effects were reported.
    Our previous research showed their efficacy in terms of reduction of Apnoea-Hypopnoea Index, total sleep time in the supine position; improve oxygen saturati...
