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.

Summary
Brief summary
Cerebral palsy (CP) is the most common disability in childhood. CP is characterized by impaired mobility, which depends on muscle mass and spasticity. Therefore, one of the major focuses of therapy in CP children is to increase muscle mass and power, decrease spasticity and consequently improve mobility, weight bearing and bone health. Unfortunately, there is a void in therapeutic interventions aimed at increasing muscle mass and function, bone mass in CP children. Vibration therapy (VT) has the potential to fill this therapeutic gap. A recent extensive study using vibration therapy in adolescents with CP has shown improvements in mobility, bone strength, and muscle mass. We assume that younger children may benefit similar or even more due to their growth and development period. There is however sparse information regarding the use of vibration therapy in younger individuals with CP and robust study designs and assessments are required. This study aims to identify the benefits of VT in children with CP aged 5-12 years old and identify the best protocol of the VT for this age group.
