Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention group members used of a physical activity self-management program delivered via the internet. The intervention program was branded "Get Set" and was developed as an eight module, highly interactive internet program based upon social cognitive theory, incorporating education, quizzes, goal-setting, self-reflection and positive role-modelling. Modules were released weekly onto the Get Set website. Intervention group participants received a one-on-one introduction to the Get Set website prior to commencement of the program, and were encouraged to log in at least weekly for the program’s eight week duration.

Secondary outcome [5] 8800 0
functional capacity was measured using the six minute walk test. The six minute walk test is a simple, sub-maximal, clinical exercise test, in which the distance walked under controlled conditions in six minutes is measured.

baseline, immediately post-intervention (10 weeks post-baseline) and 10 weeks post-intervention (20 weeks post-baseline)
Secondary outcome [6] 8801 0
self-reported physical activity behaviour was measured using the Multimedia Activity Recall for Children and Adolescents (MARCA). This is a computer-based, self-report tool that records young people's use of time in a 24 hour period. It was administered by phone interviews.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants were recruited via Novita Children’s Services, the sole provider of community-based therapy, equipment, and support services to children with physical disabilities in South Australia. They were sent a letter describing the study and inviting them to participate. Once eligibility and participation in the study was confirmed, participants were matched for Gross Motor Function Classification System (GMFCS) level (the single most important determinant of physical activity level in this population) and randomly assigned to intervention or control groups. Allocation was concealed, since recruitment of the entire cohort of participants was completed prior to any subjects being allocated to groups.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Each participant's name was recorded on a card and these were then sorted into three gross motor function categories (based on the severity of their cerebral palsy). Cards from each category were then placed face down and shuffled. Two names were drawn at a time to create random pairs of participants from the same gross motor function category. A coin toss was then used to randomly assign one person from each pair into the intervention group (internet-program), with the remaining person going into the control group (usual care). This process was completed for each gross motor function category. Where
there was an odd number of participants in a gross motor function category, a coin toss determined the group allocation of the lone participant.
