Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the study will perform whole body vibration therapy (WBVT) four times a week for 20 weeks. Each training session consists of three 3 minute WBVT with three minute rest breaks between each WBVT. Participants will weight bear (stand with or without aid) on a vibration plate that moves rapidly ( 12-22Hz) up and down over a small distance ( up to 10 mm) generating vibration stimulus. The vibration causes the muscle in the leg and truck to contract. Training sessions performed at schools are supervised by a physiotherapist. Training sessions performed at home are supervised by parents/caregivers with orientation and weekly visits from physiotherapist.

Eligibility
Key inclusion criteria
adolescents with heterogeneous motor disability that is not cerebral palsy ( GMFCS II-IV) aged between 10-20 years. This would include patients with: mild to moderate spina bifida, genetic/disease motor disorders and injury related motor disorder. To be included in the study participants must be able to stand on the vibration plate ( with or without assistance) and be able to undertake evaluation assessments.
Minimum age
10 Years
Maximum age
20 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Participants will be excluded if:1)They have a fracture within 8 weeks of enrolment, pregnancy and acute thrombosis, muscle or tendon inflammation, renal stones, discopathy or arthritis. 2) There is a history of clinically significant organic disease or findings on physical examination, which in the opinion of the Investigator would prevent the patient from completing the study. 3)There is a history of using any of the following medications, regardless of dose, for at least 1 month, within 3 months of enrolment: anabolic agents, glucocorticoids (does not include inhaled glucocorticoids) or growth hormone. Participants will not receive Botulinium toxin injection throughout duration of the study.
