Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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
Participants will be allocated into Group A (6-weeks aquatic exercise) or Group B (6-weeks land exercise) first. Participants will undertake both exercise blocks with a washout period of 1 week in between. Both the aquatic and land – based exercise interventions will involve one session per week, lasting 60 minutes, for 6 weeks.
Exercise sessions for both the land and water based interventions will be conducted as per current evidence for exercise and chronic heart failure and the land programme will reflect that currently conducted at each trial site. As such, both programmes will include a warm up and cool down period of 10 minutes duration, as well as a combination of upper limb and lower limb aerobic and resistance activities. Each session will also include 10 minutes of balance activities. Exercise intensity will be similar in both the land and water based programmes (9-13 on the Borg scale), ensuring that the only difference between the 2 groups is the type of exercise performed (ie water versus land).

Outcomes
Primary outcome [1] 259934 0
Six minute walk test - change in walking distance
Timepoint [1] 259934 0
baseline, 6 weeks, 13 weeks
Secondary outcome [1] 268840 0
Balance outcome- using the Balance Outcome Measure for Elder Rehabilitation (BOOMER)

The BOOMER is a global measure of standing balance incorporating 4 commonly used balance tests including: the Timed Up and Go test (TUG), functional reach test (FRT), step test and the static standing with eyes closed test. Results from tests are combined to provide a single score for each individual.

Secondary outcome [2] 268841 0
Quality of Life - using the Minnesota Living with Heart Failure Questionnaire (MLWHFQ)
Timepoint [2] 268841 0
baseline, 6 weeks, 13 weeks
Secondary outcome [3] 401438 0
Grip strength: Grip strength will be measured using a handheld Saehan dynamometer. Three measures will be performed on each arm and the best result recorded.
Timepoint [3] 401438 0
Grip strength will be measured at baseline, week 7 following the initial training intervention and week 14 following the second training intervention.
Secondary outcome [4] 401439 0
10 metre walk speed: Walk speed will be measured on a 14 metre flat track. To account for acceleration and deceleration effects, the time taken for the participant to walk only the middle ten metres of the track was recorded. Participants were asked to undertake the test at both a comfortable “like a walk in the park” and fast “like hurrying for a bus” pace. Two tests were performed for each test using their usual walking aid and the shortest (best) result for each test was recorded.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants who have completed the 12 week multidisciplinary rehabilitation programme and who are deemed eligible to participate in the project will be approached by the programme staff and informed about the trial.

Usual care for these patients entails referral to a community based exercise programme, prescription of a home based exercise programme or an invitation to continue at the hospital for an additional 12 weeks of maintenance exercise. As such, participation in this project will have no impact upon usual care.

Those participants who express an interest in participating in the project to the programme staff, will then be approached by the Principle Investigator at each trial site and provided with the PICF and consent form.

Consenting individuals will be randomly allocated by concealed opaque envelope method into the order in which they will undertake the two therapy blocks, i.e. either AB or BA. Randomisation will be done by a co-investigator not involved in recruitment or delivery of the intervention.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will be conducted using a computer random number generator program.
