  • Research summary

    This research will assess whether low intensity vibration (LIV) therapy can increase bone-growth in length of the tibia and femur of the shorter leg in children aged 6-12 years with a documented history of leg length discrepancy, recruited via clinical musculoskeletal, orthopaedic, physiotherapy and podiatric practitioners.
    The aim is to assess the potential of this safe, non-invasive and potentially cost-effective method for levelling leg-length in children under clinical treatment for LLD to try to avoid epiphyseodesis surgery and minimise longterm musculoskeletal disability.

    All subjects will have accurate LL measurement at baseline and then LL measurement monthly over 13 months (4 months pre-treatment, 3 months intervention and 6 months follow-up). LL measurement is taken using a portable ultrasound and laser system, which is safe, accurate, reproducible and validated against standing digital x-ray measurement.

    At the fourth visit, the child will be randomised to one of the 2 intervention groups and will attend the clinic 3 times per week for treatment. All measurements will take place at the Sayer Clinic in London W8 outside school hours, at a time to suit the family.

    Randomisation
    Subjects will be randomised into one of 2 treatment groups with the following parameters:

    1. 0.4 g and 30 Hz
    2. 1.0 g and 30 Hz

    The randomisation schedule will be computer-generated with random permuted block sizes. Assignments will be kept in sealed opaque envelopes by a member of the study team who has no contact with subjects.

    The Intervention groups of children referred with pre-existing leg length difference, will receive LIV therapy for 15 minutes, 3 times per week over three months between months 4 and 7, standing with their shorter leg on a vibration platform at 30 Hz and low amplitude of 0.3 or 1.0g (less amplitude than experienced by a child walking or running)
