  1. Fabricating for Tone Reduction • Tony Wickman R.T.(O,P) • freedom fabrication inc.

  2. What Is Tone? • Tone literally means activation of a muscle. • Spasticity is derived from the Greek word meaning to pull or draw.

  3. Cast Correction: • Cast may require greater than normal correction • Make sure to correct cast at the articulating surfaces

  4. Dorsiflexion Angle • Maximum dorsiflexion deviation should be no more than 20 degrees. • Watch for cavus arch !

  5. Plantarflexion Angle • Plantarflexion angle should be no more than forty degrees. • Watch for plantarflexed metatarsals

  6. Inversion/Eversion Angle • +/- 15 degrees • Cast corrections are difficult

  7. Mold Modification • The model must accurately mimic the patients physiology • You have to have intimate knowledge of skeletal structures!

  8. Maleoli Buildups • Buildups should be more “extreme” than usual • Take into consideration varus valgus tendencies

  9. Medial Maleoli/Navicular • Two apexes • Blend well into surrounding soft tissue

  10. Calcaneal Cuboid Buildup • Include achilles tendon extension • Be sensitive to prominent heels

  11. Heel Buildup • Heel should be rounded • Heel should be symmetrical

  12. S.T. Groove • Anatomy rules • Blend into longitudinal arch

  13. Medial/Lateral Arches • Smooth transition • Connect around to plantar surface of calcaneus

  14. Cuboid/ Lateral Fifth Met Head • Relieve 1.5-3.0 mm • Be careful to maintain radius of plantar lateral surfaces

  15. Metatarsal Relief • Proximal edge relief • Distal edge relief

  16. Padding Techniques • Bony prominences only • Blend edges smoothly • Colored foams

  17. Material Selection • Polypropylene • Polyethylene • Copolymer

  18. Pulling Plastic • Focused stretch • Proper temperature • Maximum vacuum

  19. Trimming Plastic • Establish trim lines • Poly posting is ground first • Trim lines must be smooth

  20. Finishing & Decorating • Colored Velcro • Foams • Ribbon • Transfers
