Elements and Performance Criteria

1. Select corrective orthoses materials
   • Materials are selected that reflect client condition requirements and requirements for durability and performance
   • Other health professionals are consulted if necessary, to clarify or provide additional information
2. Make initial 3D design on cast
   • Design is consistent with material characteristics
   • Design is consistent with client anatomical features and condition needs
3. Produce technical drawing of corrective orthoses
   • Drawing correctly specifies materials to be used in corrective orthoses construction
   • Drawing correctly specifies anatomical matching, key references and specific performance requirements of corrective orthoses
   • Dimensions and tolerances are correctly specified, including appropriate use of drawing symbols
4. Review the cast
   • Cast is reviewed for accuracy, material selection, three-dimensional design and consistency with technical drawing and prescription if present
   • Changes and refinements are made as necessary, including balancing aesthetic needs with condition and footwear requirements
5. Make diagnostic fitting if appropriate
   • Mock orthoses are made to specified dimensions and allowance made for final materials if necessary
   • Diagnostic fitting is made and results interpreted for possible changes to corrective orthoses design and materials
6. Produce and post basic form
   • Basic form is produced to fitting accuracy
   • Basic form reflects features that need to be checked for modification or refinement
   • Basic form is corrected and posted to corrective orthoses standard
7. Produce trial fitting corrective orthoses and conduct trial fitting
   • Trial fitting corrective orthoses are produced
   • Trial fitting corrective orthoses simulate key characteristics of corrective orthoses, including desired corrective action and dimensions
   • Diagnostic fitting is made and results interpreted for possible changes to corrective orthoses design and materials
   • Existing shoes, if provided, are modified for trial corrective orthoses
8. Produce corrective orthoses
   • Corrective orthoses are produced, taking into account original assessment of client needs and results of trial fitting, in accordance with OHS practices
   • Allowance is made for any variation between trial orthoses and final corrective orthoses for example temporary posting
   • Dimension and shape of corrective orthoses are checked against specifications in technical drawing
   • Lining closures and additional padding are fitted as required
   • Existing shoes, if provided, are checked against corrective orthoses and modified if necessary
   • Corrective orthoses are finished off to established quality standards
9. Deliver and fit corrective orthoses
   • A check is made of fitting and adjustments made if necessary
   • Client is informed of function, management and maintenance procedures for corrective orthoses
   • Arrangements for follow-up are explained to client
   • Other health professionals are informed of supply of corrective orthoses where appropriate
   • Supply of corrective orthoses is noted in client records
10. Follow up client
    • Client is followed up according to schedule set at time of corrective orthoses supply and appointments made if necessary
    • Function and state of corrective orthoses are checked
    • Client condition is assessed and further medical grade footwear treatment or other health professional treatment arranged if necessary
