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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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
Patients will be required to attend the Hollywood Functional Rehabilitation Clinic 3 times per week, for 1.5 hours. The rehabilitation intervention is for twelve weeks and will be fully supervised by an Accredited Exercise Physiologist (Miss Chrissie Mavros).

The rehabilitation intervention consists of four stages, with the ultimate goal of restoring function of the affected limb to 80% of the unaffected limb, or aged matched population from published normative data.

Stage 1 aims (wks 1-2): restoring hip, knee and ankle range of motion (ROM); re-activating and recruiting the appropriate lower limb muscles; introducing cardiovascular exercises.

Stage 2 aims (wks 3-5): strengthening the lower limb musculature; introducing core stability; further developing cardio-vascular fitness.

Stage 3 aims (wks 6-8): develop lower limb muscle strength simulating functional tasks.

Stage 4 aims (wks 9-12): restore and improve physical function during all activities of daily living.

Outcomes
Primary outcome [1] 258510 0
To improve the physical and psychological function of patients.

This is going to be assessed through 5 tools:
1) The six minute walk test: which measures functional ambulation capacity
2) the up and go test: also measures physical function
3) The Toronto Extremity Salvage Score: is a self administered questionnaire specific for limb salvage patients. It measures physical function and describes changes over time
4) The short-form 36 question: measures mental and health dimension (self-administered questionnaire)
5) High mobility assessment tool: assesses uni-dimensional function through various physical tests.
Timepoint [1] 258510 0
2 baseline tests (administered 2 weeks apart). If these two tests are not within 10% of each other a third baseline test will be administered. If this test is not within 10% of the second baseline test, the patient will be omitted due to instability in their results; 12 weeks (this will occur the week following the last rehabilitation session)
Secondary outcome [1] 264315 0
Secondary outcomes is lower limb muscle strength.

Muscle strength is made up of four components:
- Knee flexion/extension: will be measured by an isokinetic dynamometer
- Hip flexion/extension: will be measured isotonically via a 3repetition maximum protocol
- Hip abduction: will be measured isotonically via a 3repetition maximum protocol
- plantar flexion: will be measured isometrically via a cable tensiometer.

If this test is not within 10% of the second baseline test, the patient will be omitted due to instability in their results; 12 weeks (this will occur the week following the last rehabilitation session)
Secondary outcome [2] 264373 0
Joint range of motion.

Hip Flexion/Extension will be measured by a bubble inclinometer, knee flexion/extension and ankle plantar-flexion will be measured by a goniometer.

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Only patients of Professor David Wood and Dr Richard Carey Smith will be recruited for the study. Patients will be sent a subject information sheet and an expression of interest form from their orthopaedic surgeon, with contact details of the study coordinator.

Each patient will receive the rehabilitation intervention, with their contra-lateral limb acting as their own control

Summary
Brief summary
This study looks at how supervised exercise programs can help in rehabilitating people with a major loss of muscle or nerves following surgery for sarcoma.

Who is it for?
You can join this study if you are recovering from a major loss of muscles or nerves after surgery for sarcoma.

Trial details
Participants will take part in a 12 week supervised rehabilitation program with exercises, 3 times per week, for 1.5 hours. The opposite unaffected limb is not used in the exercise program, and is monitored for comparison. Five tools will be used to monitor the psychological and physiological wellbeing of patients. The ultimate goal is to restore function of the affected limb to 80% of the unaffected limb,
The study aims to see how well exercise is tolerated, and how effective exercises are at increasing muscle strength and mobility, and also quality of life.
