We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Primary outcome [1] 0 0
Effectiveness of a self-administered automated hyperinsufflation technique for 2 years, versus standard management, on respiratory infection risk within 2 years after randomization, in patients with MS. - This will be evaluated by the incidence of lower respiratory infections requiring antibiotic therapy
Timepoint [1] 0 0
24 months
Secondary outcome [1] 0 0
Effect of COUGH-ASSIST on slowing the decline in respiratory function, - This will be demonstrated by monitoring respiratory function by spirometry
Timepoint [1] 0 0
12 months and 24 months
Secondary outcome [2] 0 0
Functional effectiveness of COUGH-ASSIST - By using the goal attainmentscaling method (GAS)
Timepoint [2] 0 0
12 months and 24 months
Secondary outcome [3] 0 0
Tolerance and compliance with COUGH-ASSIST, - This will be evaluated via an online "patient reported outcomes form" and data readings from the internal memory of the COUGH-ASSIST
Timepoint [3] 0 0
24 months
Secondary outcome [4] 0 0
Effectiveness of COUGH-ASSIST in reducing the risk of serious respiratory infection - This will be evaluate by the number of serious respiratory infection
Timepoint [4] 0 0
24 months

Brief summary
In patients with neuromuscular disease, chest mobilization by hyperinsufflation slows
respiratory decline by almost 80% compared to controls, and prevents complications like
pneumonia, atelectasis and respiratory distress.

This insufflation technique improves the airway clearance and reduces the need for invasive
ventilation. It also improves CV and DEPtoux in patients with neuromuscular pathology
