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

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

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

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

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

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

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

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

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

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

11 Heel Buildup n Heel should be rounded n Heel should be symmetrical

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

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

14 Cuboid/ Lateral Fifth Met Head n Relieve mm n Be careful to maintain radius of plantar lateral surfaces

15 Metatarsal Relief n Proximal edge relief n Distal edge relief

16 Padding Techniques n Bony prominences only n Blend edges smoothly n Colored foams

17 Material Selection n Polypropylene n Polyethylene n Copolymer

18 Pulling Plastic n Focused stretch n Proper temperature n Maximum vacuum

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

20 Finishing & Decorating n Colored Velcro n Foams n Ribbon n Transfers
