Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treadmill training; frequency: 5 days/week; duration: 8 minutes/session; belt speed: 0.2m/s.
The intervention started when infants were able to produce 10 supported steps on a treadmill within 1 minute trial (as long as it happened before turning 13 months corrected age, if they were to be included in this study). Treadmill training continued until the infant was observed walking 3 independent steps over ground, or the infant turned 24 months corrected age.

Comparator / control treatment
The control group did not receive treadmill training. All families were visited on a monthly basis to videotape five 1-minute trials of the infants stepping while being supported on a treadmill.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Recruitment via high risk clinics of local hospital, doctors referred potential subjects, and after checking exclusion/inclusion criteria, the assigned ID was entreted into a computer program for group allocation by a statistician unaware to which group the subject would be allocated (central randomisation)
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation was conducted via a computer program considering 3 stratification factors: age, gender, birth weight
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Summary
Brief summary
The purpose of this study was to examine the potential benefits of treadmill training in infants who are at risk of having delays related to their movement development. In addition, previous research has suggested that there might be a relationship between how infants perform their steps on the treadmill and the age of onset of independent walking. Therefore, this has also been explored.
Hypotheses: treadmill training in infants at risk for developmental delays may: a) lead to earlier onset of walking; b) increase the number of steps taken per minute; and c) improve correct foot positioning during stepping relative to an untrained control group.
