Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Inspiratory muscle training - similar to resistance training of limb muscles except the target muscle group is the inspiratory muscles. Inspiratory muscle training involves inhaling through an threshold inspiratory muscle training device for 10 minutes, three times per day for 32 weeks.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment by sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted Block Randomisation
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Participants are blinded to whether they are receiving sham or treatment intervention. The assessor 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.
