Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

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

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)
Foreknowledge of the upcoming allocation to order of treatments was completely prevented by use of a method equivalent to the examples provided (central allocation, sequential numbering of identical containers).

As each participant arrived for their first testing session, internet-based software was used to generate a random number from 1-10. The random production of an odd versus an even number determined their order-of-treatment allocation (rather like tossing a coin). This process occurred subsequently to assessment of their eligibility and enrolment into the study and it was repeated for each participant. It was thus impossible that anyone could have foreseen participant assignment at the time of enrolment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The order in which the participants received the procedures was determined at their enrolment for the study by random number generation of an odd or even number (simple randomisation created by computer software).
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Crossover
Other design features
Participants were not told that one condition was designed as a control. Participants faced away from experimenter during measurement of sway to reduce possible body language transmission of expectation.
Phase
Not Applicable
Type of endpoint/s
Efficacy
Statistical methods / analysis
2-way analysis of variance or non-parametric equivalents.

Prior to the study sample size required to detect change in sway measurements of an effect size of 1.5 (centre of pressure length changes = 20 mm), and with 80% statistical power, was calculated to be 6. Additional participants were recruited to allow for withdrawals from the study.
