Modern modular foot-orthoses systems allow an integration of the cost and efficiency benefits afforded by the use of pre-formed semi-rigid FOs components, while simultaneously allowing a high degree of individualisation of prescription. Such systems, while popular, still remain unproven. Recent studies in paediatric rheumatology have made a contribution in developing guidelines with regards to pharmacological intervention in arthritic children. In addition, specific drug therapy protocols have been published to effectively help general practitioners, physiotherapists and ophthalmologists to successfully treat children with JIA patients (BSPAR 2006; Hull 2001; NICE guidelines 2002). A Cochrane systematic review on treatment of pes planus, highlighted that children with JIA were excluded as a group from most of the studies (Ashford et al. 2005). At present little evidence exists for the podiatric management of children affected by this disabling pathology, especially for orthotic management. This research has provided evidence to support the use of readily available off-the-shelf FOs in treating JIA children.
