Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will perform vibration therapy using the Galileo Basic vibration plates (Novotec Medical, Pforzheim, Germany). Each session will last 18 min: 3 min vibration followed by 3 minutes rest- repeated 3 times. Sessions will be performed 4 times a week, over 20- week periods. Each intervention group will have their own target intensity: either 20 or 25 Hz.
Training sessions will be performed at home or at school. An exercise physiologist from the research team will supervise the participants performing training at home once a week and all 4 days of the week for those doing it at school, in order to monitor progress and provide feedback/support. Parents/caregivers will provide ongoing supervision of home sessions.
Intervention code [1] 312945 0
Treatment: Devices
Comparator / control treatment
Before the intervention period, all participants will have a control period (lead-in) for 12 weeks. 12 week control period is the main comparator to assess the effects of two different vibration therapy protocols (20 Hz and 25 Hz).

During the control period, participants will continue their usual activity levels and standard care with no vibration therapy.
