Vibration Intervention For Bone Enhancement In Childhood Cancer Survivors
This study is a two arm parallel allocation of participants to either the intervention or
control group will be utilized for a one year trial.
Participants will be randomly assigned to stand on a low magnitude, high frequency
mechanical stimulation device ("vibrating") platform for 10 minutes twice daily for one
year. Participants in the control arm will stand on a placebo device.
This study will evaluate the effects of low magnitude, high frequency stimulus on bone
mineral content(BMC), bone mineral density (BMD), and bone strength in childhood cancer
survivors who present with BMD values 1.0 or more standard deviations below the mean for
their age and gender for the lumbar or whole body. This study will evaluate the effects of
low magnitude, high frequency stimulus on markers of bone turnover in childhood cancer
survivors who present with BMD values 1.0 or more standard deviations below the mean for
their age and gender for the lumbar or whole body.
At baseline participants will have evaluations to determine bone mineral content and bone
mineral density (Dual X-ray Absorptiometry and Qualitative Computed Tomography) and a blood
sample collected to measure biomarkers of bone turnover, hormonal status and Vitamin D
metabolism. Anthropometrics and tanner stage will be obtained at baseline, 3 months, 6
months, 9 and 12 months. A physical activity monitor will be worn for a 7 day period and a
food frequency questionnaire will be completed. Tibial length will be measured. Participants
have a blood sample collected either at home or at St. Jude Children's Research Hospital
(SJCRH) every 3 months during the study to measure biomarkers of bone turnover, hormonal
status and Vitamin D metabolism, anthropometrics and tanner stage, physical activity monitor
and food frequency questionnaire. All measurements and evaluations required at baseline will
be repeated at the completion of study visit.
Interventional
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
The outcome measures for this study are bone mineral content (BMC), bone mineral density (BMD), and bone strength that will be measured at baseline and following the 12 month intervention.
