Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

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.

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

Intervention assignment

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.
