Description of intervention(s) / exposure

Other interventions - Sham polysomnography

Experimental: Intervention - This trial of PSG-assisted commencement of non-invasive ventilation (NIV) in motor neurone disease (MND) follows the methodology of our previous single-site study (Hannan et al 2019 ERJ), with the addition of an open label cohort that extends until (the earlier of) 12 months or death.

After empirical NIV set-up and an acclimatisation period (3 weeks), participants will undergo single night in-laboratory polysomnography (PSG). The PSG will be performed and supervised by a sleep scientist. In the intervention group, the "intervention" PSG results will be used to adjust/titrate NIV settings to optimize ventilation and improve synchrony between the patient and the NIV device. Participants will be asked to continue to use NIV as prescribed for the subsequent 7 week intervention period.

Placebo comparator: Control - The participants allocated to the control group will also be asked to attend a single night in-laboratory PSG. The NIV settings will not be adjusted throughout the PSG ("sham" PSG). Participants in the control group will retain their original settings after the sham PSG, and will be asked to continue to use NIV in this manner for the subsequent 7 week intervention period.
