Improving Low Bone Mass With Vibration Therapy in Adolescent Idiopathic Scoliosis (AIS)
Improving Low Bone Mass With Vibration Therapy for Girls With Adolescent Idiopathic Scoliosis (AIS) - A Randomized Controlled Trial
This is a prospective randomized controlled trial investigating the effect of vibration therapy on bone mineral density (BMD) and bone quality in AIS subjects suffering from osteopenia (low bone mass).
Scoliosis is a three-dimensional spinal deformity and AIS is the commonest with a high prevalence of 2-4 % in the general population. As many as 30% of AIS subjects also suffer from osteopenia which can persist and result in serious health problems later in life including vertebral collapse, fragility fractures, decreased quality of life and even mortality. In spite of this, a safe, effective and evidence-based treatment protocol for AIS-related osteopenia is not available. It remains uncertain how effective dietary advices, physical activity, Calcium and Vitamin D supplements are in this regard. On the other hand, low-magnitude high-frequency vibration therapy was shown to be effective in increasing bone mass both in animal models and in clinical trials involving elderly subjects. AIS-related osteopenia may have a different clinical behaviour. In addition, the in-vivo effect on bone quality has never been studied. We plan to carry out a scientific clinical study on the effect of vibration therapy on skeletally mature female AIS subjects with osteopenia. They are randomly allocated to either the treatment or the control group. BMD, bone micro-architectures are assessed to delineate whether vibration therapy has any therapeutic effect on improving low bone mass in osteopenic AIS subjects.
Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)

The patients receive treatment by standing on the Vibration Platform 20 minutes a day, five days a week. The platform will deliver a vibration of 0.3g with a vertical displacement of 0.085mm at 35 Hz.
  • Experimental: Treatment Group
    This group will receive Vibration Therapy.
    Intervention: Device: Vibration Platform
  • No Intervention: Observation Group
    This group does not receive Vibration Therapy
