10、The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-g
11、overnmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described
12、 in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the

17、ribing their products and for those reporting on the devices used in the treatment of their patients and their effects.This document proposes the adoption of the term “foot orthotics” for this field of orthotic practice. It also specifies the clinical objectives for the use of these devices and desc
18、ribes their functions and constituent components.Manufacturers trade names and details of materials and manufacturing processes have been avoided.

26、t orthotic devices may be used to achieve the following clinical objectives:a) to relieve pain;b) to promote balanced standing and walking;c) to manage deformities which are:1) reducible (flexible) (e.g. pes planus);2) irreducible (fixed) (e.g. fixed equinus);d) to control joint instability (e.g. an
27、kle ligament insufficiency);e) to compensate for abnormal limb length and/or foot length or shape;f) to protect tissues (e.g. diabetic neuropathy and inflammatory arthropathy);g) to promote healing (e.g. foot ulcer);h) to stimulate motor-sensory feedback.5 FunctionsThe function of the device may be:
28、a) for deformities:1) to reduce or correct a deformity (i.e. to move a reducible (flexible) deformity into an improved alignment and hold the correction obtained);2) to hold a deformity (i.e. to prevent a fixed deformity from increasing);b) to control the alignment of a joint;c) to control the motio
29、n of a joint;d) to compensate for abnormal limb length and/or foot shape and size;e) to reduce or redistribute the load on the foot;f) to apply increased pressure on a specific area(s) of the foot surface.6 Classification and description of devices6.1 ClassificationThree classes of device are recogn
