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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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
Supervised exercise training for the lower limb, 3 times weekly for 8 weeks. Lower limb exercise training will consist of at least 15 minutes of stationary cycling at 60% peak workrate achieved on the incremental cycle test and 15 minutes of walking training at 80% of the average walking speed achieved on the six minute walk test. Training duration will be uncreased to 20 minutes of cycling and 20 minutes of walking by the 12th training session.

Rehabilitation
Comparator / control treatment
Usual medical care with no exercise training or advice on exercise training for 8 weeks. Usual care - management of medications by general practitioner (GP) and possibly respiratory physician.
Control group
Active

Eligibility
Key inclusion criteria
Subjects will have a medical diagnosis of lung disease from dust inhalation including silicosis, asbestosis or asbestos related
pleural disease (ARPD). Subjects on long-term oxygen therapy will be included in
the study.
Minimum age
35 Years
Maximum age
86 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria

musculoskeletal, cardiovascular or neurological conditions likely to adversely
affect performance during exercise assessment or training; have an inability to
understand English; or have participated in a pulmonary rehabilitation program
within the last 12 months.

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)
Subjects will be randomised after initial baseline testing by a computer program. Allocation will be concealed by sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
computer-generated sequence
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
In this study the comparisons are between exercise training and no training. Because of the type of training the subjects and therapist will not be blind to group allocation and it is not possible to make a sham treatment for these. The assessor will be blind to group allocation.
