Tone Relieving Ankle Foot Orthoses (TRAFOs) have been used in the management of neurophysically impaired patients for some years within the United States and during the last few years they have been introduced in the UK. The main difference between a TRAFO and a standard polypropylene ankle foot orthosis (AFO) is that the TRAFO does not have a flat base beneath the foot, but one with various raised and hollowed areas. This unique base is designed to hold the foot in a neutral position and provide support and stability under the dynamic arches of the foot. The investigation aimed to determine any benefits of using TRAFOs in the management of children with cerebral palsy in comparison with those obtained using standard anide foot orthoses. Fifteen children were recruited into the investigation and assigned to one of two groups. Group 1 were monitored in standard AFOs for six months and group 2 were monitored in AFOs for three months and then in TRAFOs for a second three month period. The subjects were assessed at regular intervals during the six month period using EMG analysis to establish changes in the pattern of muscular activity during gait. Video analysis and force platform data was also used to determine general gait parameters and record ground reaction vectors. Results for EMG and the temporal and spatial parameters were unable to highlight any areas in which tone-relieving ankle-foot orthoses produced more favourable results than standard polypropylene ankle-foot orthoses. The results suggest that TRAFOs may not work in the neurological manner previously indicated and may have no greater benefit to a patient than a standard polypropylene AFO.
