Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The training group will complete a standardized 3 month period of respiratory training using a threshold inspiratory muscle trainer. Participants will train 3 times each day for 10 minutes each session. Training pressure will be set at a minimum target % of maximum inspiratory pressure. Participants will be trained in the use of the device and will perform daily training. Participants will be assessed every 2 weeks when training pressure will be adjusted accordingly to maintain the target pressure.

Comparator / control treatment
Control patients will use a modified device that does not affect airway resistance or pressure.

Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females

Intervention assignment
Parallel
Other design features
Participants are blinded to whether they are receiving sham or treatment intervention. Therapists administering training are blinded to whether participants are in sham or treatment groups. The assessor (different to therapist) is blinded to whether the participant was in sham or treatment group. Another independent analyst will assess the data and will be blind to whether participants were from sham or treatment groups.

Summary
Brief summary
This study will investigate whether exercise training of respiratory muscles can slow the inevitable decline in respiratory function in patients with MND, and thereby improve quality of life. The hypothesis is that respiratory training will result in maintentance or improvement of respiratory and functional outcomes in patients with MND.
